About this list
How do you know these are really YC companies?
Every company is matched against YCombinator's public company directory and then verified one by one against the company's own site. A surprising number of unrelated companies share a name with a real YC startup, so name matching alone is not enough. Only confirmed YC-funded companies get a badge.
What does the badge year mean?
It is the YC batch the company went through, shown as YC 2016 and so on. Winter and Summer batches both count, and companies that later went public or were acquired still count as YC.
How is the list ranked?
The most recognized employers come first, then companies are ordered by how many AI roles they have open right now. Role counts come straight from company careers pages and refresh daily.
How do I apply?
Each company links to its profile on AI Job Signal with its live openings, and every role links out to the company's own application page. Nothing sits between you and the employer.
