Who is Sridhar Vembu?

Sridhar Vembu is the co-founder of Zoho Corporation, a privately held Indian software company that sells business apps such as Zoho CRM, Zoho Mail and ManageEngine to customers worldwide. He was CEO until January 2025, when he became the company's Chief Scientist. He received the Padma Shri in 2021.

Where is Sridhar Vembu from?

He was born in 1968 in Umayalpuram, a village on the Kaveri in Thanjavur district, Tamil Nadu, and grew up mostly in Chennai, where his father worked at the Madras High Court. Since late 2019 he has lived in Mathalamparai village near Tenkasi.

What is Sridhar Vembu's education?

He earned a B.Tech in Electrical Engineering from IIT Madras in 1989 and a PhD in Electrical Engineering from Princeton University in 1994, with a thesis in information theory supervised by Sergio Verdu.

How did Sridhar Vembu start Zoho?

After about two years as an engineer at Qualcomm in San Diego, he co-founded AdventNet in 1996 with his brothers, Tony Thomas and other friends, selling network-management software to equipment makers such as Cisco. The company used no venture capital, survived the 2001-02 telecom bust, launched Zoho-branded web apps in 2005 and renamed itself Zoho Corporation in 2009.

What is Sridhar Vembu's net worth in 2026?

Forbes India's 2026 rich list put Sridhar Vembu and his siblings at No. 46 with a combined US$5.8 billion. Company filings reported in the press show Sridhar personally holds only about 5% of the Indian parent company; his sister Radha Vembu holds about 47.8% and brother Sekar about 35.2%.

What is the Sridhar Vembu divorce controversy?

In a divorce case in California, his estranged wife Pramila Srinivasan alleges he moved Zoho's ownership to his siblings without her consent; in January 2025 a court ordered him to post a US$1.7 billion bond. Vembu denies ever transferring his shares and his lawyer says the order is invalid and under appeal. The case was pending as of October 2026.

Since 27 January 2025, co-founder Shailesh Kumar Davey has been Group CEO, Mani Vembu leads Zoho.com, Rajesh Ganesan leads ManageEngine and Tony Thomas leads Zoho US. Sridhar Vembu is Chief Scientist, focused on research and development.

Will Zoho launch an IPO?

Vembu has said for over 15 years that Zoho will stay private. In September 2025 he wrote that a public company facing quarter-to-quarter pressure would very likely not have built a product like Arattai.

Where it began

Around the year 2000, a Silicon Valley venture capitalist slid a term sheet across the table to a soft-spoken engineer from Chennai. The offer, as Sridhar Vembu later recalled it to The Economic Times, valued his little network-software company at about US$200 million. There was one catch: a clause that required the company to list or otherwise give investors an exit within about eight years [19]. Other accounts of the episode put the valuation lower, but they agree on what happened next [23]. Vembu said no.

“They called me arrogant,” he told the newspaper [19]. Years later he gave Forbes India the simpler reason: “Why sacrifice freedom? That is the primary reason” [15].

That refusal explains almost everything about the man and the company. Zoho Corporation, the firm that grew out of that small business, now reports more than Rs 12,000 crore in annual revenue [33][34] and more than a million paying business customers [4]. It has never taken venture capital, never listed on a stock exchange, and is run, in spirit at least, from a village in the far south of Tamil Nadu where its founder cycles past paddy fields [71][87]. It has also given him one of the more complicated public lives in Indian business: celebrated as a model of self-reliance, criticised for his politics and some of his public statements, and caught in a long, bitter legal fight in a California divorce court.

A Kaveri childhood, a Chennai upbringing

Sridhar Vembu was born in 1968 in Umayalpuram, a village on the Kaveri in Thanjavur district. It was his mother’s village, and he was born in her parents’ home [15]. His father’s village, Chidambaranathapuram, lay about 30 km down the river, and the boy spent long stretches of his childhood there [15]. Both sides of the family came from small agricultural households [20][82].

His father, S. Vembu, moved to Chennai and spent more than 30 years working in the courts, mostly the Madras High Court. Forbes India reported that he retired as head of the section of private assistants [15][20]. His mother was a homemaker [20]. Sridhar was the eldest of five children: three younger brothers, Kumar, Sekar and Mani, and a younger sister, Radha [15][20]. All of them would later appear in the story of the company.

There was no internet in that Chennai home. Newspapers were the boy’s window on the world. Vembu has credited the investigative journalism of Arun Shourie in The Indian Express: “I was born in 1968, and in my formative years, I read The Indian Express and was shaped by his fearlessness” [15].

He studied at Anjugam Higher Secondary School in West Mambalam up to Class 9, then at Jaigopal Garodia National Higher Secondary School in East Tambaram, finishing Class 12 in 1985 [20]. Forbes India reported that he topped his class and cleared the IIT entrance exam with an all-India rank of 27 [15].

IIT Madras and Princeton

At IIT Madras he studied electrical engineering and graduated with a B.Tech in 1989 [7][16]. The same year he went to Princeton University for a PhD in electrical engineering. “I went to Madras IIT for my undergraduate and came to Princeton to do my PhD in 1989,” he told the entrepreneur-interviewer Sramana Mitra [17]. He completed the doctorate in 1994, with a thesis titled “Information Theory without Ergodicity Assumptions: Some New Results”, supervised by the information theorist Sergio Verdú [8]. A paper from that work, co-written with Verdú and Yossef Steinberg, appeared in the IEEE Transactions on Information Theory in 1995 [9].

By the end of the PhD, however, he had lost faith in academic research. He accepted a lecturer’s post at the Australian National University in Canberra and even paid for permanent residency, then pulled out. “I had the remorse and I thought ‘I actually don’t like what I am doing, I don’t like this work and research, I don’t believe in it anymore’,” he told the Sydney Morning Herald. “I was 26 and I called them up and apologised” [22].

The first break

Qualcomm and a brother’s conversation

In 1994 Vembu joined Qualcomm in San Diego, working on CDMA wireless systems, especially the algorithms that control the power of mobile signals [7][17]. “My PhD is in electrical engineering, so I really do not have a software background,” he said later [17]. At Qualcomm he was exposed to software for the first time and found he liked it [22]. His brother Kumar was also working at Qualcomm at the time [17][18].

The two brothers talked constantly about what to do next. “My brother Kumar and I were in the US together in 1995 and we constantly spoke about what we could do with our talent, about how we could make a difference in the lives of people back home in Chennai,” Vembu told The Economic Times [19]. The thought that nagged them was simple, as he put it to Forbes India: India had perfect talent but produced almost no software products [16].

Vembu left Qualcomm in 1996 after about two years [7][17] and moved to the Bay Area.

AdventNet: a bedroom in Chennai, a desk in New Jersey

In his own account the company was “born sometime between late 1995 and early 1996” [23]. Zoho’s official history dates it to 1996, when AdventNet Inc. was set up in New Jersey [1]. The full picture is a little messier. Tony Thomas, an engineer who had taken a buyout from AT&T Bell Labs, ran the New Jersey side; the Vembu brothers set up an Indian company in Tambaram, Chennai; and the two were brought together under the AdventNet name, which moved to San Jose in 1998 and to Pleasanton, California, in 2000 [1][15][18][20]. Accounts differ on exactly who counts as a co-founder. Forbes India named Sridhar, Kumar, Sekar and Tony Thomas [15]; other reports speak of two brothers and three friends [16][22].

“We had very humble beginnings, in a bedroom in Chennai,” Vembu said [19]. There was no outside money. “It was all bootstrapped. There was no investment money of any kind, only some family and friends,” he said in 2007 [17]. The founders’ savings, help from family and friends, Tony Thomas’s buyout money and the salary of Vembu’s then wife, an engineer, kept them going [15][17]. “The first two years was purely about survival, how do we put food on the table,” he recalled [19]. Tony Thomas was the first CEO; Vembu was the chief evangelist and, as the only founder in Silicon Valley, the de facto salesman, though he admitted, “I didn’t know how to ask for money” [15][18].

The first product was a Java toolkit for the SNMP protocol, which network equipment uses to report its status, introduced in 1996 [10][18]. A fuller network-management framework, WebNMS, followed [10]. The model was to license the software to equipment makers, who would build it into their own products. “I started selling it to customers in the Bay area, to Cisco and folks like that,” Vembu said [17]. Developers found the toolkit through Java newsgroups, and their employers paid perhaps US$5,000 to US$10,000 a licence [18].

The moment the founders knew they had a real company came from Japan. “We realized we had a viable company when Minolta in Japan wrote us our first big cheque for $200,000,” Vembu said. “That’s why I still have a soft corner for the Japanese” [19]. Revenue went from about US$350,000 in 1997 to US$1 million in 1998, roughly doubled again in 1999, and reached about US$10 million by 2000 [17][23][24]. By then AdventNet had about 115 engineers in India and just seven people in Silicon Valley [17].

That was when the VCs came calling. “In 1996-97, no Silicon Valley VC wanted to fund us. By 2000, VCs started chasing us,” he told ET [19]. He turned them down.

Building the empire

Surviving the bust (2001-2004)

The decision to stay independent was tested almost at once. Most of AdventNet’s customers were Silicon Valley start-ups building optical and telecom gear. When the dot-com and telecom bubble burst in 2001, followed by the 11 September attacks, two to three hundred of them disappeared, about 100 of them optical-networking firms [17][18]. “It was obvious to me that the telecom market was not going to come back and all our revenue was from that market,” Vembu wrote later [24].

His accounts of how deep the fall went vary. In 2007 he said software revenue still grew in 2001 and fell in 2002, “one tough year” [17]. In 2010 he described a drop of about 30% from around US$10 million [18]. “There were times when we thought maybe we’re not really cut out for all this,” he admitted, and the founders even considered selling [18]. What saved them was cash in the bank and a refusal to panic. They cut sales staff but kept the engineers. “We did not want to let anybody go,” he said [17][18]. Telecom growth in China and Japan, where AdventNet opened offices in 2001, softened the blow [1][18]. “When the industry collapsed we had to use our internal accruals,” he said. “Each time, in 2000 and in 2008, we had enough cash to work on new technology areas” [25].

The bigger answer was a pivot. Instead of selling toolkits to equipment makers, AdventNet would sell finished IT-management software directly to corporate IT departments. That business became ManageEngine, launched in 2003 according to Zoho’s own timeline [1][17]. Customers found it through Google search ads, which became the main source of sales leads around 2004 [17]. By 2007 ManageEngine made about 70% of revenue [17]. It still makes about 40% of Zoho’s revenue today [33].

Along the way the founding team changed. Kumar Vembu left in 2004 to start his own retail software company, GoFrugal. “Kumar was instrumental in the early part of Adventnet’s success, and he scaled it up before branching out on his own,” Sridhar said [83].

The Zoho bet (2005-2009)

In 2002 Vembu bought the domain zoho.com for about US$5,000 [23][24]. It was an odd, short name, chosen for a bigger idea: office and business software delivered through a web browser, at a time when most companies still installed it from CDs. After a first collaboration product, Zoho Virtual Office, in 2004, the company launched Zoho Writer, an online word processor, and Zoho CRM in 2005 [1]. The CRM was priced at US$12 per user per month, against roughly US$65 for the market leader Salesforce [17][18].

A stream of apps followed: Invoice, People and Mail in 2008, the year Zoho opened its Austin office [1]. In 2009 AdventNet renamed itself Zoho Corporation, after its best-known brand [1][19]. Zoho had 1 million users by 2008, according to the company [1].

A school instead of a campus hiring drive

Zoho’s other early bet was on people that the rest of Indian IT ignored. As a little-known start-up, AdventNet struggled to hire graduates from well-known colleges. So it stopped looking at degrees and marks altogether [20]. In 2004-05 it started what it then called Zoho University. The first batch had six students and two teachers [3][16]. Students paid nothing and later received a monthly stipend [3][84]. “Formal education only takes you so far, but most of the contextual knowledge comes from actually doing something,” Vembu said [15][84].

The idea scaled. Renamed Zoho Schools of Learning in 2020, it now gets about 20,000 applications a year, has more than 2,000 graduates, and those graduates make up more than 10% of Zoho’s workforce. In April 2025, its 20th year, it opened new campuses in Tharuvai and Kumbakonam [3]. “We are a talent creation business, we are a talent nurturing business, not merely a talent acquisition business,” Vembu said in 2023 [26].

From 1 million users to 150 million (2010-2026)

The 2010s were Zoho’s long climb. Users grew from 15 million in 2015 to 50 million in 2019 and past 100 million by 2023, according to the company [1]. Its most important single product was Zoho One, launched in 2017, which bundled dozens of its apps into one subscription for a small business [1]. In May 2023 it launched Ulaa, a privacy-focused web browser [13].

Vembu’s view of competition was patient. “Every single product that makes our $2 billion revenue was a failure when it launched,” he said at a Mumbai summit in 2026. “We simply outlasted the failure” [77].

The financials, drawn from Registrar of Companies filings and reported by Entrackr, Inc42, MediaNama and others, show a large and very profitable business [33][34][35][36]:

Financial year	Operating revenue	Net profit
FY22	Rs 6,711 crore	Rs 2,749 crore
FY23	Rs 8,703 crore	Rs 2,836 crore
FY24	Rs 10,456 crore	Rs 3,299 crore
FY25	Rs 12,313 crore	Rs 3,191 crore

In FY25 the Zoho suite brought in Rs 7,051 crore and ManageEngine Rs 4,863 crore. North America made up about 41% of revenue, Asia about 30% and Europe 23% [33][34]. Profit dipped slightly because expenses rose about 30%, including Rs 4,347 crore on staff and Rs 2,230 crore on advertising [33][34]. Reports described Zoho as the first bootstrapped Indian start-up to cross Rs 12,000 crore in revenue [34]. For context, CapitalVia’s analysis of the RBI’s software survey found that products made up just US$2.90 of every US$100 of India’s software exports, which makes a product company of Zoho’s size unusual.

By March 2026, its 30th anniversary, Zoho said it had more than 1 million paying organisations, about 150 million users, more than 19,000 employees and more than 60 apps, with offices in 28 countries [4]. Its headquarters is in Austin, Texas, with an international headquarters in Chennai [4].

Why no VC, why no IPO

Vembu has been consistent for 15 years. “As long as I have anything I can say about it, we are not going to go public,” he said in 2010 [18]. “I will never go to a VC,” he said in 2016 [21][25]. “I stay out of the VC ecosystem because I fundamentally don’t believe in it,” he said in 2022 [28]. His argument is that outside money changes what a company spends on. “Venture capital forces you to grow faster by investing more heavily in sales and marketing, as opposed to R&D,” he told Business Today in 2023, adding that even public companies “are subject to quarter to quarter pressure” [26]. “Valuations disappear all the time and I have stayed away from value bubbles,” he said in 2022 [27]. Compare that with the path of Nithin Kamath, another bootstrapped Indian founder, or with the listed IT giants built by N. R. Narayana Murthy and Shiv Nadar.

In September 2025 he made the point again, in the middle of his messaging app’s sudden popularity: “Arattai would very likely not have been built by a public company that faces quarter to quarter financial pressure. We essentially ignore short term profits, as long as we don’t lose money” [80].

How the wealth is held

Here the public picture surprises many readers. Forbes India lists the fortune as “Sridhar Vembu & Siblings”: No. 47 at US$6 billion in 2025, and No. 46 at US$5.8 billion in its 2026 list [11][12]. Hurun’s India lists have instead named his sister: the 2024 Hurun India Rich List put Radha Vembu at Rs 47,500 crore, then India’s richest self-made woman [86].

The reason is the shareholding. Company filings for FY22, reported by Inc42 and Forbes, show Radha Vembu holding about 47.8% of Zoho Corporation Pvt Ltd, the Indian parent, Sekar Vembu about 35.2%, Tony Thomas about 8% and Sridhar Vembu about 5% [14][37]. According to those reports, the Indian company was set up in December 2010; by late 2011 Radha held 49%, and Sridhar and Tony Thomas received their 5% and 8% stakes after AdventNet’s intellectual property was sold to the Indian company for US$50 million [14][37]. How those stakes came about is at the heart of his divorce litigation, described below. Vembu says the family is “merely a custodian of the wealth; we get to direct it to good causes” [26].

Going home: Tenkasi and the rural offices

In 2011 Zoho opened a small office in a thatched shed in Mathalamparai, a village near Tenkasi, with six people [1][73]. By late 2022 it had about 750 staff there, roughly 600 of them local [72]. The Week reported in 2025 that the campus had about 1,200 staff [73].

In November 2019 Vembu himself moved from the Bay Area to Mathalamparai [71][82]. He described an ordinary village day to Deccan Herald: morning and evening walks, hours with his gadgets switched off talking to neighbours, an electric autorickshaw. “After tasting this life in a village, it would be very hard for me to move to any major city anywhere now,” he said [71]. “I’m actually in a village. I’m happier than ever,” he said in 2026 [77].

His theory is that Indian cities drain talent from everywhere else. “What I call ‘top-soil’ erosion, with ‘talent’ as the ‘top-soil’, is not good for culture,” Zoho’s rural-revival page quotes him [5]. “For every job that we bring, there is 10-fold multiplier effect in the area,” he told Outlook Business, adding that Zoho was “cautious that we do not end up making Tenkasi into a giant metropolis” [72]. Zoho now has a network of small-town offices, from Renigunta in Andhra Pradesh to Kottarakkara in Kerala [1][73], and calls its wider approach “transnational localism”: global reach, but local offices, local hiring and local pricing, including in places like McAllen, Texas [74]. That approach is part of why CapitalVia’s data notes that India’s fastest-growing job market is not a metro.

Arattai, government email and the swadeshi moment (2025)

Zoho’s messaging app Arattai (Tamil for “chit-chat”) had been soft-launched in January 2021 [63]. In late September 2025 several Union ministers publicly endorsed it, and it went viral. Daily sign-ups jumped from about 3,000 to about 3.5 lakh in three days, which Vembu described as a 100-fold rise; the app “suddenly went vertical,” he said [63][65]. It topped the social-networking chart on India’s App Store [65]. Vembu said he wanted messaging to be interoperable “like UPI and email and not closed like WhatsApp today,” adding, “We do not want to be a monopoly ever” [63].

At almost the same time, the central government’s email moved to Zoho. Under a 2023 tender run for the National Informatics Centre, Zoho was chosen as the system integrator [57]. By October 2025 about 12 lakh accounts had been reported as migrated, and Home Minister Amit Shah publicly switched his own email to Zoho Mail [57]. In a 1 April 2026 Lok Sabha reply, the government said 16.68 lakh accounts had moved at a cost of Rs 180.10 crore, and that it retained ownership of the data [58].

The leadership handover and the AI bet (2025-2026)

On 27 January 2025 Vembu stepped down as CEO and became Chief Scientist. “In view of the various challenges and opportunities facing us, including recent major developments in AI, it has been decided that it is best that I should focus full time on R&D initiatives,” he wrote. “The future of our company entirely depends on how well we navigate the R&D challenge” [29][30]. Co-founder Shailesh Kumar Davey became Group CEO, his brother Mani Vembu took charge of Zoho.com, Rajesh Ganesan of ManageEngine, and Tony Thomas of Zoho US [29][30].

In July 2025 Zoho released its own large language models, called Zia, in 1.3, 2.6 and 7 billion-parameter sizes, hosted in its own data centres in the US, India and Europe [2]. Vembu has been sceptical of the money pouring into AI infrastructure. “As a rule, we have stayed away from monster-bets-on-other-people’s-money approach to business,” he wrote in October 2026, saying Zoho would invest in foundational AI research but “await a less bubblicious time to invest in infrastructure” [79]. At a Bengaluru conference that month he went further, saying that “as much as we think of China as adversaries, I actually look to them as gurus” on technology [78].

The setbacks and failures

The telecom bust

The 2001-02 collapse was the closest the company came to failing. Hundreds of its customers vanished, revenue fell and the founders considered selling [17][18]. The lesson Vembu took, keeping a large cash cushion and never depending on one market, shaped every decision after.

The chip plan that was shelved

In December 2024 the Karnataka government approved a Rs 3,425.6 crore silicon-carbide semiconductor unit near Mysuru proposed by Silectric Semiconductor Manufacturing, a Zoho venture, as part of a wider plan of about US$700 million [31][32]. In May 2025 Zoho shelved it. Reuters reported, citing two sources, that it could not find a technology partner [31]. Vembu wrote: “We wanted to be absolutely sure of the technology path before we take taxpayer money. We did not have that confidence in the tech so our board decided to shelve this idea for the time being” [32].

Arattai’s fade

The Arattai surge did not last. Industry data cited by Storyboard18 showed monthly active users of about 4.35 million in October 2025 and about 4.09 million in November, while new downloads fell sharply, and by early November the app had dropped out of the top 100 on both Google Play and the App Store [64]. The app was also criticised for launching without end-to-end encryption for text chats (see below) [61].

Failed experiments and a pay freeze

Not every rural bet worked. Diginomica reported that a rural office Zoho tried in Japan failed [74]. Vembu also repeats that most Zoho products failed at launch before eventually succeeding [77].

In October 2026 he announced that there would be “no usual pay increase this year” at Zoho, that it had cut marketing spending, and that it would “work hard to avoid mass layoffs.” He said headcount had been flat for 18 months while AI and server costs had risen four-fold [69][70]. Critics pointed out that he had urged Indians in the US to come home only days earlier [69]. It was a frank admission of pressure for a company that had grown for three decades. The wider data shows the squeeze: CapitalVia noted that AI jobs grew 20% while software jobs shrank 4% in September 2026.

Controversies and allegations

The divorce and the dispute over Zoho’s ownership

Allegation: In a divorce case in the Alameda County Superior Court in California, Vembu’s estranged wife Pramila Srinivasan alleges that he moved Zoho’s intellectual property to India and placed most of the Indian company’s shares with his siblings without her knowledge or consent, which she describes as “fictitious transfers” of community property that California law treats as jointly owned [14][38]. Vembu filed for divorce in August 2021 [14][37]. Her claims were first reported by Forbes in March 2023, based on a January 2023 filing. Forbes reported that the evidence cited included depositions, among them one from Vembu’s uncle Ram Srinivasan saying “Sridhar asked me to hold it”, and early cap tables of the Indian company [14]. In January 2025 the court ordered Vembu to post a bond of about US$1.7 billion, appointed a receiver over Zoho’s US entities and some personal assets, and halted a planned restructuring. The order said he had “acted without regard for respondent’s interests in community assets” [38][39]. The order was first reported in January 2026 [38].

Response: Vembu has denied the allegations. “I never ever transferred my shares in the company to anyone else,” he wrote in March 2023, and called it “complete fiction” that he had financially abandoned his wife [40]. He told Forbes that the proceeds from the 2011 IP sale were still held by the US company, and said a US tax audit had concluded the sale was an arm’s-length transaction [14]. In January 2026 his lawyer Christopher Melcher said the bond order was “invalid, cannot be complied with, and is on appeal”, that the receivership was stayed on appeal, that Vembu had always held about 5% of Zoho, and that he had offered his wife half of his shares [39]. Her lawyer, John Farley, said no court had found the bond order invalid and that it remained in force [39].

What happened next:

October 2025: the California court asked Indian courts, through Letters Rogatory, to help record evidence from witnesses in India [41].
February 2026: Pramila Srinivasan asked the Madras High Court to execute that request and record testimony from nine witnesses, including Vembu and his siblings; the court issued notice and later asked for counter-affidavits [41][42].
April 2026: Vembu had filed his counter-affidavit, Radha Vembu and Zoho sought dismissal of the plea, and the judge called the case “increasingly complex” [43].

Status: Pending. As of 24 October 2026 the California case has not gone to trial, the parties disagree about whether the bond order is in force, and no appellate ruling or final Madras High Court order on the evidence request has been reported. No court has made a final finding on the ownership allegations.

The RSS event and political alignment

Allegation: In January 2020, social-media users and critics attacked Vembu, and a #BoycottZoho hashtag trended, after he agreed to be a guest at “Resurgent Bharath”, an event organised by the RSS in Chennai [44]. A former employee had earlier written that Vembu reacted with hostility when he criticised the RSS on Zoho’s internal network; the employee later resigned [45]. Commentators, including a January 2026 Newslaundry profile, have described him as a “swadeshi mascot” of the Sangh parivar [81].

Response: “I don’t decide my views based on Twitter attacks… please do what your conscience dictates and I will do what mine dictates,” Vembu said [44]. Zoho did not respond publicly to the former employee’s account [45].

Status: A public and political debate. No legal or regulatory matter is involved. In February 2021 he was appointed to the National Security Advisory Board, which he said was about “technology led rural development” [46].

Public statements that drew criticism

Allegation: Several of Vembu’s posts on X have drawn wide criticism, each reported by multiple publications:

February 2025: he wrote that not knowing Hindi is “often a serious handicap” for Tamil Nadu’s tech workers, drawing criticism from DMK leaders in a state where Hindi is a sensitive subject [48][49].
October 2025: he shared a report claiming links between vaccines and autism and said children were being given too many vaccines. Doctors criticised the remarks, and a Scroll commentary called them “anti-science disinformation.” Large scientific studies have not found a link between vaccines and autism [50][51].
November 2025: he urged young people to marry and have children in their 20s as a “demographic duty”, and the entrepreneur Namita Thapar, among others, criticised the advice [52].
January 2026: he defended IIT Madras director V. Kamakoti’s remarks on research into cow urine, which the Congress party mocked [85].

Response: He clarified the Hindi post, saying that only poor students in government schools miss out on Hindi while private CBSE schools teach it [49]. On vaccines he stood by his view and criticised what he called a “maximalist” medical position [51]. No response to the criticism of the marriage post was reported [52].

Status: Public debate only; no legal proceedings.

His bribery claims against the former Tamil Nadu government

Allegation: In June 2026 Vembu alleged on X that approvals for his trust’s rural schools in Tenkasi and Theni had faced delays and money demands under the previous DMK government, and that they were cleared once the new TVK government took office [53][54]. He did not publish documents or amounts. DMK supporters called the claims a fabrication meant to help the new government [53][54].

Response: Vembu said he “will not be intimidated” and alleged that he had received verbal threats [53].

Status: Unproven allegations by Vembu; no complaint, investigation or legal action by either side has been reported.

Government email and Arattai’s privacy questions

Allegation: Critics questioned the move of central government email to a single private, proprietary vendor. A Wire op-ed called it “a dangerous outsourcing of national sovereignty,” and The Ken examined the risk of vendor lock-in [59][60]. Separately, privacy experts and users criticised Arattai in 2025 because text chats were not end-to-end encrypted [61].

Response: Zoho said NIC-appointed auditors empanelled by CERT-In audit its systems periodically [57]. On Arattai, Vembu said encryption based on the Signal protocol was being accelerated. He also wrote that “sovereign power always prevails over mere companies,” a remark that drew criticism [61]. In November 2025 he confirmed text encryption was rolling out [62].

Status: Policy debate; no legal or regulatory challenge to the email contract has been reported, and Arattai’s encryption gap was addressed with the rollout.

Company lawsuits: Freshworks, FlexyPe and a tax case

Allegation: In March 2020 Zoho sued Freshworks, a Chennai-born rival, in a US federal court in California, alleging misuse of trade secrets. An amended complaint alleged a Freshworks employee accessed Zoho’s systems and took about 4,000 sales leads [55]. In April 2026 Zoho filed a Rs 10 crore defamation suit in the Madras High Court against payments start-up FlexyPe and its co-founder over LinkedIn posts alleging “serious discrepancies in Zoho Books” [66]. Separately, the Income Tax Department rejected a Zoho refund claim of about Rs 57.1 crore relating to the equalisation levy [68].

Response: Freshworks said the access was by a sales employee acting “not … at the direction of Freshworks” and that it had remedied the harm [6]. FlexyPe’s posts remained up while the case continued [67].

What happened next:

December 2021: Freshworks and Zoho settled, and Zoho dismissed the lawsuit; terms were not disclosed [6][56].
April 2026: the Madras High Court refused to order FlexyPe’s posts taken down at the interim stage [67].
June 2026: the Madras High Court quashed the tax department’s rejection of Zoho’s refund claim and ordered it to reconsider [68].

Status: Freshworks case settled and dismissed (2021); FlexyPe suit pending; tax case decided in Zoho’s favour and sent back for reconsideration. No SEBI, ED, CBI, CCI or criminal proceedings against Vembu or Zoho have been reported as of 24 October 2026.

Giving back

Vembu’s giving is less about cheques than about institutions he runs himself.

The biggest is the Zoho Schools of Learning, which has trained more than 2,000 young people for free, many from small towns and Tamil-medium backgrounds, and paid them a stipend while doing so [3][20].

The most personal is a school in the villages around Tenkasi. It began in the 2020 lockdown as tuition for three children, which he called a “lockdown experiment.” By October 2020, about 254 children were attending free open-air classes with free meals, grouped by ability rather than age [76]. By February 2021 hired teachers had taken over. “I am no longer a teacher at the school,” he said, adding, “We plan to start a school in every rural centre” [71]. The school, Kalaivani Kalvi Maiyam, has since been joined by a second free school in Theni [54][81].

Zoho also funds a “Zoho Chair” in electrical engineering at his old college, IIT Madras, launched in 2018 [7]. And Zoho’s rural offices are, in Vembu’s framing, his main social project: jobs that let young people stay near home [5][72]. “Change, I believe, will not come from the middle class but from those in India’s hinterland,” he told The Better India [75].

He has received the Padma Shri (2021), which he dedicated “to our employees, my extended family, for keeping the faith” [47], as well as EY Entrepreneur of the Year (India) in 2019 [16].

Succession

Zoho’s succession is already in motion, and it is unusual. When Vembu stepped back in January 2025 he did not hire an outsider. He handed the CEO role to Shailesh Kumar Davey, a co-founder who had led engineering at ManageEngine, and kept the leadership within the founding group: his brother Mani Vembu, Rajesh Ganesan and Tony Thomas [29][30]. Vembu describes his own role as research-first: “Zoho is primarily an R&D-driven company. I’m chief scientist for a reason,” he said in 2026, adding that he spends about 70% of his time on deep technical work [77].

Ownership is a separate question. Most of the Indian parent’s shares are held by his siblings Radha and Sekar [37], and the structure is the subject of the California litigation, so its long-term shape may depend on how that case ends. Vembu has repeatedly said there will be no IPO [80].

What their journey teaches

Saying no to easy money can be a strategy, not stubbornness. Turning down a term sheet worth hundreds of millions of dollars in 2000 looked foolish to Silicon Valley. It let Vembu spend on research instead of marketing and survive two downturns on his own cash [19][25].

Keep enough in the bank to outlast a crash. AdventNet survived the 2001-02 telecom collapse not because it saw it coming but because it had cash reserves and was willing to pivot to a new set of customers [17][25].

Talent is everywhere; credentials are not. Zoho Schools of Learning started with six students nobody else was hiring, and its graduates now make up more than a tenth of a 19,000-person company [3][4].

Patience beats a perfect launch. By Vembu’s own account most Zoho products failed at first. Zoho priced CRM at a fraction of Salesforce’s price and kept improving for two decades [17][77].

Know when to stop. Shelving the chip project before taking public money, because the technology path was not certain, was a setback, but it was also discipline [32].

A founder’s voice is a company’s risk too. Vembu’s posts on politics, language and vaccines have drawn backlash, and his personal legal fight now runs through Zoho’s ownership structure. Founders who speak loudly and hold assets through family structures should expect both to be examined closely [14][44][50].
