Doesn’t Y Combinator get 7% of every business for only $125,000? How are they not flush with cash?
“Both investments happen at the same time; they are not contingent on any milestones.”
So from a founder perspective, that’s very friendly.
Either way, in the context of the top-level commenter's question, it's worth emphasizing that a change in valuation isn't a cash flow. YC doesn't get an influx of cash to invest when the value of its portfolio companies goes up, and it doesn't have to give up cash that it could otherwise invest when those companies' valuations go down.
