@konstantimb Hi Konstantin, congrats on the launch. This is very useful, any plans to add other accels (techstars, a16z etc)
ExploreYC
@zolani_matebese would be interesting to do for sure. I plan to open source this project and let people contribute !
@konstantimb the startup idea validator is the killer feature here. most founders are terrified of finding out their 'unique' idea was actually attempted in the s16 batch and failed. being able to find those similar companies and actually see their outcomes is way more valuable than just a generic 'good idea' from an ai. supported
It would be useful to have an AI search for such companies. Is something like that planned? I would look into tourism with AI features, if such things even exist.
ExploreYC
@natalia_iankovych you can search between all of the almost 6k companies with your idea yo ee if there are similar companies and so on.
ExploreYC
@natalia_iankovych do you have anything more specific in mind?
@konstantimb I couldn’t find where on the website you can enter a custom prompt and discover similar startups. Maybe I was looking in the wrong place?

Update: ExploreYC is now open source 🚀
the Product Hunt launch was something else - thank you to everyone who upvoted, broke things, DM'd ideas, and pinged me at 2am about edge cases.
because of that response I'm doing something I'd been thinking about for a while: opening the entire codebase.
the full stack is now on GitHub - React + FastAPI, the idea validator, the success predictor, the hiring board, the email digest pipeline, the cron handlers, all of it.
same code that's running at exploreyc.com right now!
there are two ways to contribute:
- have an idea for a feature? Open an issue describing it. Even half-baked ones — I read everything.
- want to build it? Open a PR. First-time contributors very welcome — happy to review, pair on the hard bits, and ship anything good.
a few low-hanging fruits I'd love help with: better filters on the hiring board, batch-comparison views, plugging in non- YC data sources, and a proper CLI mode.

if you've been looking for an excuse to commit to a real, deployed product instead of another todo-app-final-v3.. this is it 🔥

@konstantimb Awesome, just made a PR! :)
5,773 YC companies as a structured data layer is exactly the kind of work that compounds — once the dataset is well-shaped, every downstream question gets cheaper to answer. Did the same thing on the finance side at Eloquens (https://www.eloquens.com/channel/samir-asadov-cfa) building project-finance / DCF / LBO templates as a structured catalogue (renewables-focused), and the lesson that surprised me was: volume isn't the moat, the schema is. Two well-shaped DCF templates with consistent assumption tables beat 200 sloppy ones every time. Curious how you're versioning the 20 years of YC history — do batches stay frozen, or do you re-derive metrics when YC's own definitions evolve (e.g. "AI" tag, "deep tech", etc.)?

Such a cool idea! I remember how you were manually checking startups that were being added to the new batches, but this website is much cooler. I made a PR with a couple of fixes and a new graph for the analytics so you can track industry focus through time 👀
Love the Wrapped feature--a great iteration on Spotify's idea. How far back does the history go? It would be epic to see the og 2005 YC graphic :)
ExploreYC
@joe_setpoint will add support for it 🔥
Congrats @konstantimb looking to play with it more in the coming days. Subscribed already. The interactive map is pretty cool :)

@ivaylo_sekoulitchki means a lot from you!
