Deadstack

A public archive of failed startups and lessons

5 followers

Deadstack is a curated archive of real startup post-mortems that helps founders learn from failure before they build. Search and explore why products failed, what went wrong, and what founders learned. Instead of chasing success stories, Deadstack reveals repeatable mistake patterns in funding, growth, product, and execution so builders can make smarter decisions and avoid costly errors.
