Ask HN: Is There Any open source company data?

[ankit84]

From the user's email domain, i would like to get basic company info, industry, company size, geo, publicly known revenue, etc.

Tried checking, but couldn't find any free to use, open company data. Any suggestions?

(This is for GTM automation.)

The basic Dun & Bradstreet subscription is $50/mo, low enough that I think most just turn it on/off when they need to refresh their cached data. (i.e. turn subscription on, run api client with something like jcache enabled, set a long/infinite lifetime on the cache, hit the api with a list of 50 companies you’ll use for testing, turn off subscription)

For production, you use a subscription account, the $50/mo is worth it to have accurate/current entity data.
