low confidence
andromede.ai ↗ · Status: active confirmed · Founded 2025

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.

Buyer analysis

Best fit: Buyers needing custom RL environments and verifiers derived from real-world data for post-training/evaluating long-horizon agentic models.

How we verified this

Confirmed this is the correct entity: Andromede / andromede.ai, an early-stage RL data lab (Lausanne, founded 2025) that programmatically generates RL environments, tasks, and verifiers for long-horizon agentic tasks, matching the directory note on 'long-horizon sequential reasoning.' Not confused with the unrelated 'Andromeda AI' (GPU/compute startup) or 'AndromedAI' on PitchBook. Official site and LinkedIn snippet corroborate private-beta status, ~2-10 headcount, and 'small set of partners' (no named customers; notable_customers correctly left empty). PitchBook returns HTTP 403, so founded-year and HQ rest on a search snippet plus the Unusual Ventures portfolio corroboration (kept 'reported'). KEY CORRECTION: the draft missed that Andromede is in Unusual Ventures' published portfolio, a credible first-party investor source, so notable_investors now lists Unusual Ventures (reported); however no round amount or valuation is disclosed anywhere, so total_raised/last_round/valuation remain unknown. Also surfaced two co-founders via LinkedIn/Scholar: Alexandre Sallinen (EPFL, Meditron medical-LLM contributor, a genuine researcher) and Guillaume Allegre (ex-BCG X, MIT, NY-based, Founder & President), enabling researcher_backgrounds, researcher_count (~1 researcher), and a likely Lausanne/NY distributed setup. No SOC 2, trust page, certifications, papers, or named customers were found; those stay unknown/empty. Overall confidence remains low given paywalled financials and absence of a public team page.
