ExploreYC - Open-source API for Y Combinator & a16z company data

This looks awesome! I love data viz/aggregation like this. What are some things people have built with this data?

are all the companies hiring + job listing included?

An open-source API across YC + a16z with a 30-second free key is exactly the data layer I would rather hit than scrape and babysit myself for founder/sourcing research. The one thing I would test first: how fresh is the funding/exit/hiring data, is it re-crawled on a schedule (and roughly how often), or is a chunk of it a static snapshot from launch that drifts over time? And what are the rate limits on the free key before I would need to self-host the open-source side?

going from web app to a real API is the right move, that was always going to be the limiting factor for anyone who wanted to build something on top of the data instead of just browsing it. adding a16z alongside YC is a nice bonus too, cross-referencing overlap between the two portfolios could surface some interesting patterns. how fresh is the data kept, is it a scheduled scrape or closer to real time when a company updates their info

I like that you exposed the same dataset as an API instead of only a UI — the `source=yc|a16z|all` filter is the bit I'd probably reach for first. Curious if rate limits are per key only, or also per endpoint when people build public dashboards?

Open-sourcing the API for YC and a16z data is an interesting positioning move, most tools in this space keep the data layer proprietary. Curious what the actual business model is if the API is free and open-source, does the web app and AI tools layer carry the monetization or is there something else going on?

The hiring insights and batch analytics stand out since most YC directories focus on basic company search. How often is the underlying data refreshed, and do you surface historical changes so users can spot trends over time rather than just a snapshot?

Congrats on the second launch. Merging both portfolios into one schema sounds like the unglamorous hard part — YC has batches and a public directory, a16z is scattered across press pages. Which fields refused to line up between the two?

How fresh is the data on hiring and funding, and does it pull directly from YC's API or are you scraping public sources to keep it updated?

Open-sourcing the YC and a16z dataset is handy. Where's the underlying data sourced from, and how often does it refresh? Trying to gauge how stale the funding and status fields get between updates.
