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?
ExploreYC
@bidavkubra60771 pulled daily
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.

@chielephant you can check the open source GH repo to see what we do - pulling data daily from the YC web pages
Merging YC and a16z into one dataset, the part I'd want documented before building on it is entity resolution. Last time I stitched company data across two sources, matching 'same company, different record' ate most of the effort: OpenAI vs OpenAI Inc vs matching on domain, then deciding which source wins when the funding stage disagrees. Do you expose a stable canonical company ID across both, and when YC and a16z conflict on a field, is there a documented precedence?
ExploreYC
@dipankar_sarkar this will be a challenge, there isn't conflict a the two don't have much conflicting companies... but will be big challenge once we start adding more sources
are all the companies hiring + job listing included?
ExploreYC
@loup_wang yes
Is it free?

@ethan_lee8 open source == free
Congrats on the launch! 👏
Love the idea of making YC data much more searchable and actionable.
Curious.....what's been the most unexpected way early users are using ExploreYC?
ExploreYC
@worksforme very happy you like it!!
I come from the investing side, where structured data on private companies usually sits behind expensive paywalls, so open-sourcing this is a real gift. How fresh is the data, and what's the source when a company hasn't announced anything publicly?
ExploreYC
@henry_s_jung the data is freshly polled every single day man!
