AfterQuery is a San Francisco applied research lab, backed by Y Combinator, that turns expert work into AI training data: fine-tuning examples, reasoning traces, grading rubrics, agent environments and computer-use demonstrations. It raised a $30 million Series A at a $300 million valuation in April 2026. Specialists and generalists join talent pools, and projects typically run two to three weeks, paid every Friday through Stripe.
