AfterQuery

AfterQuery is an applied research lab that curates data solutions to accelerate foundation model development. It focuses on building datasets and training data techniques that improve models by modeling expert reasoning and real-world workflows.

The product builds datasets that reflect how experts solve problems, including high-quality prompt–response pairs, chain-of-thought reasoning traces, and reinforcement learning rubrics. It offers expert-designed prompts with grading frameworks, agent environments across APIs/tools/services for training and evaluation in real workflows, and human-demonstrated trajectories across browser and desktop use to teach models to navigate software end-to-end.

Who it’s for: Enterprises and AI researchers needing domain-specific, expert-curated training data to improve foundation models and agent performance across real-world tasks.
