* They IPOed and are still in business.

* If I had taken the offer, the stock would have been worth between 50k and 150k per year, depending on when I sold it. Their estimate of 100k per year was spot-on.

So they were being honest. Good to know! They were late enough stage when I was applying that they could do a fairly reasonable valuation. I think I would have been much more likely to take the offer if I had information like this in writing.

I still think I was right to value the equity much lower, since I had no way to know if they were being honest at the time.
