AfterQuery hits $3.2B valuation, YC's fastest unicorn ever
AI training-data startup AfterQuery has reportedly raised new funding valuing it at $3.2 billion, just five months after its $30 million Series A priced it at $300 million. Y Combinator partner Gustaf Alströmer called it the fastest launch-to-unicorn run in the accelerator's history, achieved by founders who are just 22 and 23 years old.

The jump reflects surging investor appetite for companies that supply specialized human expertise to train AI models on professional-grade reasoning, not just factual accuracy. It also signals intensifying competition among data-labeling startups like Mercor and Scale AI as major labs race to improve agentic and task-based model performance.
- AfterQuery's valuation rose more than 10x in under six months.
- The startup trains AI on professional reasoning patterns, not just correct answers.
- Its client roster reportedly includes Nvidia, Legora, and Motif Technologies.
