This is really cool. BUT, I think most HN readers would be most interested in the founding stories, and the hustle / hurdles overcome / pivots that these founders showcased.

For instance, there's no mention that Slack came out of a failed game company or that Uber was originally supposed to just be on-demand limos for a small group of friends! These are the key parts of the stories that are missing.

Nice project but the content doesn't match your headline. This is a collection of 30,000ft facts that would be more suited to a boilerplate "our company history" on a corporate website. There's no insight or learning to be had here about how each company reached these milestones.

Collecting genuine insights in one place could be pretty useful!

I clicked on a couple of the stories I know well from first-hand experience and found a lot of mistakes. This is a neat idea but if it's just assembling headlines it will miss the insights that would actually help founders.

hm, isn't trying to learn from success stories a mistake called "survivor bias" ? https://en.wikipedia.org/wiki/Survivorship_bias
