So what do all these startups do that can not raise a series A? A subset sell as a team buy, a few go out of business, but an increasing number are going out for a bridge round. Basically, instead of raising $5 million, I am seeing post-seed startups raise anywhere from $500K to $1.5 millon, at a valuation somewhere between a series A and a seed valuation, with the hope that the additional capital will give them time to gain more traction or scale their business. A good option for bootstrapped companies that have exhausted their friends and family but aren't ready for gasoline on the fire.
