With more startups winding down lately [1], I was wondering:
What are some of your favourite startups that unfortunately didn't work out? Whether your involvement was as a builder, user, or just a fan of their mission.
Bonus points if the founder has written a thoughtful retrospective / post mortem that documents the decision and explains why their idea was ultimately not viable as a business.
