Planet First Partners

The management committee draws from Executive Chairman Frédéric de Mévius and Managing Partners Manu Gupta and Nathan Medlock. Gupta brings 20 years spanning Lakestar, Goldman Sachs, and Oracle; Medlock sourced exits at Zouk and worked at Warburg Pincus and Lehman Brothers. Partners Emil Mahjoub, Madeleine Hood, and others lead vertical sourcing, but material investment decisions are made collectively at the partnership level.

The firm runs a dedicated ecosystem approach combining direct executive networks from its partners and a set of aligned advisors — Kestrel, Lcap, Efeso — alongside fund commitments to Quantonation, Eka Ventures, and Obvious Ventures. Those LP positions provide early visibility into quantum, consumer health, and sustainable-consumption deal flow before companies scale to growth stage.

It operates as a regulated growth-equity asset manager, not a family office. The firm was founded in 2020 by Frédéric de Mévius after his exit from Verlinvest, but it raises and manages third-party capital rather than managing a single-family balance sheet.

It does both — direct growth-equity and venture-stage positions sit alongside fund commitments. Disclosed LP relationships include Quantonation II, Eka Ventures, and Obvious Ventures, ensuring exposure to seed and Series A climate, health, and inclusion startups that complement later-stage direct investments.

The firm publicly states that a material portion of its carried interest is contingent on achieving measurable social and environmental targets set at the portfolio-company level. Head of Sustainability Sergio de Carvalho embeds these KPIs during due diligence and negotiates them into investment terms, making sustainability performance an economic incentive, not just a reporting obligation.

The firm does not publish an exclusions list. Its investment mandate requires that portfolio companies deliver a substantial contribution to the transition to a sustainable economy, which implicitly screens out fossil-fuel extraction, conventional armaments, and other sectors inconsistent with a net-zero-aligned growth portfolio.

The firm often co-invests alongside other sustainability-focused managers. In May 2025 it co-led a Riverlane round with ETF Partners, and in 2024 it co-led Submer's $55.5 million raise with M&G Investments. It invites external co-investors on a deal-by-deal basis rather than syndicating through a formal club structure.
