Summary
$3.2 billion is the reported valuation in AfterQuery’s latest funding round, a leap from $300 million in April that made it Y Combinator’s fastest startup to reach unicorn status.
Five months ago, the AI training-data startup announced a $30 million Series A and said it had hit a $100 million annualized revenue run rate while working with major AI labs.
AfterQuery, founded by entrepreneurs now 22 and 23, came through Y Combinator’s Winter 2025 batch just 18 months ago and has named Nvidia, Legora and Motif Technologies as customers.
Its business sits in the fast-growing market for expert-led model training, using doctors, lawyers and other specialists to teach AI agents how professionals reason through tasks.
