After barely changing at all for decades, the startup funding business is now in what could, at least by comparison, be called turmoil. At Y Combinator we've seen dramatic changes in the funding environment for startups. Fortunately one of them is much higher valuations.

The trends we've been seeing are probably not YC-specific. I wish I could say they were, but the main cause is probably just that we see trends first—partly because the startups we fund are very plugged into the Valley and are quick to take advantage of anything new, and partly because we fund so many that we have enough data points to see patterns clearly.

What we're seeing now, everyone's probably going to be seeing in the next couple years. So I'm going to explain what we're seeing, and what that will mean for you if you try to raise money.

Super-Angels

Let me start by describing what the world of startup funding used to look like. There used to be two sharply differentiated types of investors: angels and venture capitalists. Angels are individual rich people who invest small amounts of their own money, while VCs are employees of funds that invest large amounts of other people's.

For decades there were just those two types of investors, but now a third type has appeared halfway between them: the so-called super-angels. [1] And VCs have been provoked by their arrival into making a lot of angel-style investments themselves. So the previously sharp line between angels and VCs has become hopelessly blurred.

There used to be a no man's land between angels and VCs. Angels would invest $20k to $50k apiece, and VCs usually a million or more. So an angel round meant a collection of angel investments that combined to maybe $200k, and a VC round meant a series A round in which a single VC fund (or occasionally two) invested $1-5 million.

The no man's land between angels and VCs was a
