In 2000 a venture investor offered his company US$10 million for 5%. He said no. Today Sridhar Vembu's Zoho serves more than 100 million users without a rupee of outside funding. This is the story of how a PhD from Thanjavur built it, and five lessons for founders.
From a Thanjavur village to Princeton
Sridhar Vembu was born in 1968 in a village in Thanjavur district, Tamil Nadu, into a middle-class family. He studied electrical engineering at IIT Madras (1989), then took an MS and PhD at Princeton. He worked at Qualcomm in San Diego as a wireless engineer.
1996: a trade show booth and a small team
In 1996, with Tony Thomas and his brothers, he started AdventNet. It began with personal savings and a small team in a 10 by 10 room near Chennai building network management software. Vembu has said the starting question was why India produced so much talent for export but no home-grown technology powerhouse. In the early days he joined to staff a booth at a trade show as a salesman. In 1997 the company made about US$350,000 in sales, and the founders put it all back into R&D instead of paying themselves.
The two big nos
Around 2000, a venture investor offered US$10 million for a 5% stake, valuing the company at about US$200 million, with an exit or IPO expected within seven to eight years. Vembu declined. During the 2001 dot-com crash, many venture-backed firms folded. AdventNet kept its headcount in line with revenue and held cash, and survived. A competitor then showed interest in buying it for about US$25 million. Vembu said no again.
How one product funded the next
Profits from its first product, WebNMS, funded ManageEngine, the IT management business. ManageEngine's profits funded Zoho, the online business apps suite. The company was renamed Zoho Corporation in 2009.
Moving to the village
- 2004: set up Zoho Schools of Learning to train high school graduates who could not afford college. Students get a stipend and often join the company. About a fifth of its engineers come from this programme.
- Zoho opened offices in small towns, including Mathalamparai in Tenkasi district.
- 2019: Vembu moved to Tenkasi himself.
- 2021: Padma Shri.
- Zoho has said it has more than 700,000 business customers in 150 countries. Financial Express reported FY23 operating revenue of Rs 8,703.6 crore and net profit of Rs 2,836 crore.
5 founder lessons
- Fund the next step with the last one. WebNMS paid for ManageEngine, which paid for Zoho.
- You can say no to money. Vembu turned down a US$10 million offer and a US$25 million buyout.
- Build slowly so a crash cannot kill you. Zoho kept costs in line with revenue before the 2001 crash.
- Hire for ability, not degrees. Zoho Schools trains school leavers to become engineers.
- Build where talent is. Small-town offices cut cost and kept people longer.
Takeaway
Vembu's path is slower than the venture route and not for every founder. But Zoho shows that a company can reach a very large scale with its own profits, and that rural India can be a base for global software.
