Aptura AI | Full-Time | MTS (Applied AI), MTS (SWE / Product) | London | ONSITE / HYBRID

We build the evaluation datasets and RL environments that make AI reliable where mistakes are expensive: finance, healthcare, and legal.

We design expert-curated training data, calibrated rubrics, and RL environments for nearly every frontier AI lab as well as startups pushing the frontier of what models can do.

We're a small London-based team running multiple active projects, so what you ship gets used immediately by labs, startups and internal domain experts. We recently launched SpreadsheetBench v2 (Kimi k3 model card) and work on ultra long-horizon tasks.
