Speaking from personal experience, I think a lot of them end up in the boat of having just enough paying customers that the idea looks viable but not getting enough long term traction to go from niche product surviving on raised capital to self-sustaining. Riding the initial public interest wave a bunch of people signup and the revenue projections look really good which lets the company go raise more capital to keep going, but over time, the company taps out their customer base and their revenue growth flatlines and ultimately they can't jump from niche product running on capital to self sustaining.

A lot of these postmortems, I think end up with CEOs looking at metrics, especially the early growth metrics, -- and they want to be successful, most of the time it's their baby -- and seeing enough interest to make them think they're close. Ergo, the "only if we had more time/money" postmortems.
