About Andromede

Andromede is an early-stage RL data lab that programmatically generates RL environments, tasks, and verifiers from real-world data for post-training and evaluation of frontier agents, with an emphasis on long-horizon sequential reasoning tasks. As of mid-2026 it is in private beta, working with a small set of partners. It was co-founded by Guillaume Allegre (Founder & President) and Alexandre Sallinen (an EPFL-affiliated researcher who contributed to the Meditron medical-LLM project), and is backed by Unusual Ventures.
