§ Funding Round
AfterQuery - Series A: $30M funding round led by Altos Ventures at a $300M valuation for the AI training data company with $100M+ annual run rate.
AfterQuery raised a $30 million Series A at a $300 million post-money valuation in April 2026, led by Altos Ventures with participation from The Raine Group, Y Combinator, and BoxGroup. Angels from Anthropic, OpenAI, DeepMind, Meta, and Microsoft also participated in the round.
The funding comes as AfterQuery surpassed a $100 million annual revenue run rate, just 14 months after launch. The company has built a network of nearly 100,000 verified professionals across finance, software engineering, medicine, and law who provide expert reasoning data that AI labs use to train frontier models.
AfterQuery plans to use the funds to expand its expert network, deepen domain coverage across more industries, and build out its enterprise solutions business. The round brings total funding to approximately $30.5 million following a $500K seed round in early 2025.
