Someone built a directory of 5,700+ failed YC startups with post mortems, deep analysis, and rebuild plans so you can revive dead ideas and turn them into new projects.

failed startup post mortems are underrated. founders are way more honest when there's nothing left to protect.

Dead startups are basically open-source lessons.

Wait it’s like

thx for featuring, aman! I'm one of the creators of 👋 we built it bc we think it's worth learning from past startup attempts. just bc an idea didn't work before, doesn't a remix of it won't now or in the future. lmk if you have any product feedback!

actually, i'd just like my agent to go through each one and make a common denominator things to do/avoid.

Why lump 'acquired' and 'dead' together? Acquisition is not always a failure.

I'd imagine vibe coding a startup that died as being one of the lowest % returns in the industry they didn't die because of the product (which you can now build for free) they died because the market didn't want the product

this is actually genius. why come up with an original bad idea when you can adopt someone else's proven bad idea and do it slightly less bad

cool idea

This is so cooooolllll

Fr

really interesting

True failed startups are basically free case studies for the next founders.

exactly

how many Web3 projects are there?

@DeCharge not many yet most are web2 yc startups.

900+ failed startups graveyard Check it out

Definitely a usecase for an Agent to go and analyze the market, the reasons why it failed in the first place and do competitive analysis. There would definitely be so many opportunities here!

Oh wow

soo cool, i was gonna build smtg like this after seeing this post from @brycent : maybe this can help @brycent :)

@numberkash @anandsukumaran_ startup graveyard is real now.

@AmeliaDacine @redouanedz19

absolutely love the post mortem sections

Ideas that sounded good, got tested and invalidated? Seems like a better resource to identify dead ends.

use for search next time!

NFT projects don’t even deserve to be in this space.

@jacobi_torsten If you go to producthunt archive and browse top of the days 2 years ago, 95%+ websites are inactive by now

most ideas don't fail due to concept but execution the unsexy bit of actually building and distributing is what trips people up

This is great! I had this idea after my first startup failed. Where do the learnings go? Great idea anyway and I'll be sure to contribute my failures:

5700 post mortems is basically a free mba in what not to build

@itsthewealth4me bruh lots of these have been acquired for 9 figures+

Why is it good if we try creating something that has already failed? Yes, I can understand that we can learn from the mistakes, but any reason to recreate any of them? Please enlighten me

Because most startups don’t fail due to the idea they fail due to timing, execution, or market conditions. Fix those and the same idea can work.

Makes sense, thank you very much So on which idea are you working on?

there was a quote I think it was by APJ kalam, where he said if you want to be successful learn from others failure and not success. this is a good resource for all the future founders.

Unbelievably cool. Thanks for sharing.

@mannupaaji Cool site

I've seen 3 companies from that list get rebuilt by different teams and hit 8-figures. The graveyard is actually a goldmine of validated problems with proven market demand.

The only reason: no money.

Studying failed startups is underrated. Sometimes you learn more from what didn’t work than from success stories. A lot of great ideas fail because of timing, distribution, or execution not always because the idea was bad.

Great analysis

Productised FTW. Graveyard-as-a-service is a legit pivot strategy.
