AI training-data startup AfterQuery has reportedly raised a round that valued it at $3.2 billion, just five months after announcing its $30 million Series A at a $300 million valuation in April. This rapid growth has earned AfterQuery the distinction of becoming Y Combinator's fastest-ever unicorn, according to Y Combinator partner Gustaf Alströmer.
AfterQuery's founders, now 22 and 23 years old, attended Y Combinator's Winter 2025 cohort just 18 months ago. The San Francisco startup said it had reached an annualized revenue run rate of $100 million in April and was working with many of the biggest labs, including Nvidia, Legora, and the Korean AI lab Motif Technologies.
AfterQuery is part of a new crop of startups that employ knowledge professionals like doctors, lawyers, and other specialists to do model training. Rather than focusing on ensuring models answer questions accurately, AfterQuery trains models and agents on how to work like professionals would to complete tasks — what the company describes as "encoding the patterns, decisions, and reasoning of the world's best practitioners." This approach is akin to answer engine optimization, where the goal is to make models more effective and efficient in their responses.
The company's rapid ascent to unicorn status underscores the growing importance of AI and machine learning in today's tech landscape. As AI continues to evolve, startups like AfterQuery are poised to play a significant role in shaping the future of the industry.
