How to Raise Money

There are now sites like AngelList, FundersClub, and WeFunder that can introduce you to investors. We recommend startups treat them as auxiliary sources of money. Raise money first from leads you get yourself. Those will on average be better investors. Plus you’ll have an easier time raising money on these sites once you can say you’ve already raised some from well-known investors.
