But Mr. Khosla, 55, who moved to the United States from India as a graduate student in 1976, has another motive, too. He wants to goad other rich Indians into giving away more of their wealth.

India’s torrid growth over the last decade has helped enrich many here  Forbes estimates that India now has 69 billionaires, up from seven in 2000  but only a few have set up large charities, endowments or venture capital funds.

“It surprises me that in India there is not a tradition of large-scale giving and helping to solve social problems and set a social model,” Mr. Khosla said.

Mr. Khosla is not alone in worrying about the state of Indian philanthropy. Bill Gates, the Microsoft co-founder, who was in China last week with the billionaire investor Warren E. Buffett, said Thursday that he and Mr. Buffett might go to India as part of their campaign to get the very rich to give away half their wealth.

Charitable activities and venture capital investing have been a mainstay for some Indian business families like the Tatas and for technology entrepreneurs like Aziz Premji of Wipro, the Bangalore outsourcing firm. But many others have given very little.

A recent Bain & Company study estimated that Indians give much less as a percentage of the country’s gross domestic product than Americans. Moreover, individual and corporate donations account for just 10 percent of the charitable giving in India, compared with 75 percent in the United States and 34 percent in Britain. The balance comes from the government and foreign organizations.
