ATHMOS

What ATHMOS does

ATHMOS Partners is a Marseille-based boutique operating partner founded in 2022 by Thomas Guyot that provides real estate investment sourcing, asset management, and disposition services to French and international institutional and private investors. The firm focuses on assets at pivotal points in their lifecycle with significant value-add potential — including offices, retail, hotels, logistics, and residential — and executes full business plans from sourcing and acquisition through financing, works delivery, and ultimate disposition. Active mandates disclosed include the 34NY hôtel particulier disposition on Avenue de New-York in Paris 16th, the 14REC office renovation near Place d'Italie, the HOR multi-asset portfolio (≈40 assets, €150M volume, 2026–2031 disposition horizon) for a private family, and the 87JDLF office conversion in the Auteuil district (delivery Q3 2026).

The core offering is a professional services model delivered through a four-person team: Thomas Guyot (Managing Director, ex-Schroder REIM, Morgan Stanley Real Estate, ICADE; €4bn+ career transaction volume), Valentin Ployet (Senior Investment Associate, ex-BNP Paribas Real Estate and Arkéa Real Estate), Damien Demonchy (Head of Finance, ex-Baker Tilly France CFO, EY, AXA Real Estate), and Mégane Pappalardo (Asset Manager, ex-CBRE Capital Markets). Revenue is generated through asset management fees, acquisition advisory, financing arrangement, and disposition fees, with pricing tailored to specific investor mandates and not publicly disclosed. Go-to-market is sales-led and relationship-driven, relying on direct professional networks, referrals, and LinkedIn presence rather than branded marketing.

Geographically, ATHMOS is headquartered at 31 Rue Rigaud in Marseille's 13007 arrondissement and serves French and international investors. Its named mandates span Paris (16th, 13th arrondissements) and cross-border assets, though the firm has no disclosed external institutional backing, no parent company, and no announced funding rounds to date. Technology integration, AI capability, or proprietary software platforms are not disclosed; the operating model is fundamentally human-capital-driven rather than technology-led.
