Powering every frontier AI research lab

Problem

AI researchers and enterprises are
hitting walls with suboptimal data solutions.

Today’s models can generate answers. But they struggle with real work. Because real work isn’t just outputs. It’s decisions, tradeoffs, and context. That knowledge doesn’t live on the internet. It lives inside experts.

Expertise has never been captured. Until now.

The most valuable knowledge isn’t written down. It exists in how professionals think. Not just answers, but reasoning. Decisions. Tradeoffs. Context. We work with domain experts to capture that thinking—then structure it into training data models can learn from.

Our solution

We turn real-world work into training data.

AfterQuery is an applied research lab curating data solutions for frontier foundation model development.

Models trained on outputs plateau. Models trained on reasoning improve.
We build datasets that reflect how experts actually solve problems— step by step, decision by decision.

Our data includes:
