Ask HN: Products that you loved but were shutdown

Most VC-backed businesses fail because they can't scale beyond a point.However they can be great ideas for a sustainable medium-sized business. I am trying to move away from BigTech to pivot into an SMB entrepreneur and acquire a company that needs a new home. If you have a favorite product that shut down in the recent past - I would love to get your idea and reach out to the company and get on rescue mode. Thanks!
