Something I've seen recently is the founder thats willing to let a company die.

I suspect these founders find some way to extract as much as possible from their company after raising funds.

Without naming names, I've seen a startup go boom (raise huge money and be valued at 3x that huge money), then all the senior leadership disappear: moved out of state, only show up for pre-recorded town halls (that used to be live), no longer a part of engineering meetings, cancelling department meetings, etc.

That went on for a couple years until the founder minimized their position in the company.

I don't understand how that could happen unless that founder extracted what they wanted and were just riding the ride rather than marching towards IPO.
