It wasn't so good for employees who would've wanted to sell and diversify when the valuation was, conservatively, about 2x what it is now. And maybe even 2.5x plus if you extrapolate what Stripe could've been worth at the height of the market.
For the long term company, it still could be a good, because if they can raise capital privately like they were just able to do, then they get the upside of access to money without the downside of share price fluctuations, scrutiny, more bureaucracy etcetera.
