AfterQuery raised money at a three-point-two-billion-dollar valuation in September 2026, according to Forbes. That's five months after the company was worth three hundred million dollars. Ten times bigger in half a year.
Founders Spencer Mateega and Carlos Georgescu are 23 and 22. They joined Y Combinator in winter 2025 with no product. Eighteen months later, they're running Y Combinator's fastest trip from launch to unicorn, ever.
What they sell
AfterQuery doesn't label images or tag text. The company pays doctors, lawyers, engineers, and financial analysts to train AI models on expert reasoning. Not what the answer is. How an expert thinks through the problem.
Every major AI lab already scraped the open web. Now they need proprietary data that doesn't exist online. AfterQuery had a hundred million dollars in annual revenue by April 2026. Customers include Nvidia, OpenAI's former CTO Mira Murati, and Korean AI lab Motif.
Who owns the thinking
The valuation says one thing clearly: teaching AI how you think is worth more than most people earn in a thousand lifetimes. But the expert doing the teaching doesn't own the model. AfterQuery does. The lab that buys the data does. You sold the pattern. They keep it forever.
