Atmos Capital

Atmos Capital

Atmos Capital was established in 2016 by brothers David and Andrew Carpentier. The firm operates as a multi-family office based in New York, deploying capital on behalf of a small circle of private families. David Carpentier previously spent a decade at Goldman Sachs in principal investing and merchant banking roles, a background that shaped the firm's early transactional DNA before it narrowed toward structured growth investing. The firm targets minority and control growth-equity opportunities across the technology and business-services landscape. Active subsectors include enterprise software, financial technology, and applied AI. Atmos typically structures investments as direct co-investments using special-purpose vehicles, pooling its own capital alongside the families it advises. The group has previously engaged across a range of company stages, from Series B through pre-IPO, and has participated in rounds led by established venture and crossover funds. Its geographic focus centers on North America, with selective exposure in Western Europe. Atmos maintains a lean structure consistent with a multi-family office that prioritizes deal-by-deal alignment over gathering permanent institutional AUM. The firm lists a New York headquarters and does not disclose total deployment. In recent reporting cycles, it has been observed actively participating in late-stage venture rounds, with an operational cadence governed by the two founders directly. No dedicated philanthropic arm or separately branded real-asset vehicle is publicly associated with the group. A structural differentiator for Atmos is its merchant-banking lineage: most multi-family offices emerge from wealth management, while Atmos evolved from opportunistic principal investing. This shapes a posture closer to a partner-owned deal shop than an allocator-driven family office, with investment decisions resting in a concentrated partnership rather than a broad investment committee.
