If making money was the goal, then I would have invested my surplus in a VC fund or given it to a portfolio manager who would have put it in a mutual fund or whatever. But not in Angel investing because the risks of Angel Investing are far higher...of course the potential returns are also higher.
I don't think any good idea has ever been stopped because of lack of funds. There is always someone you should be able to convince.
When I started Dataquest it was the first B2B publication in India, and there were so many detractors who would say: in India sports magazine have not worked, children's magazines have not worked, and you are talking about a computer magazine! That was the sort of message that I was getting.
And if I couldn't convince my own Guru then where would I be? I did manage to convince him. He saw that this guy is making sense, and therefore he was willing to invest. Money was available.
So I think if you have the passion, you have the idea, if you believe in it, you should be able to convince the people who have that faith in you. And you bootstrap, you start downscale and keep on building up.
Other than investors, what are sources of cash for an entrepreneur?
