Extantia Allstars

Extantia Allstars

Extantia Allstars operates as the fund-of-funds arm within the Extantia Capital platform, which was co-founded by Yair Reem and Sebastian Heitmann in Berlin. The core Extantia entity runs a direct investment strategy alongside this manager-of-managers vehicle, allowing the partnership to combine bottom-up company exposure with top-down manager selection across the climate technology and energy transition verticals. The dual structure reflects a deliberate architecture choice: one team picking startups, the other picking the VCs most likely to win those same deals. The vehicle commits capital to a concentrated portfolio of European early-stage climate venture funds. Sectors covered include carbon capture, alternative proteins, green hydrogen, sustainable mobility, and industrial decarbonization, with managers typically writing first checks at Seed and Series A. The fund-of-funds structure enables access to specialist managers that larger institutions often overlook, while the direct arm of Extantia co-invests alongside these same funds. This overlapping footprint creates an information loop between the manager selection team and the direct investment team, flagging winning syndicates and emerging managers faster than a standalone LP could. Extantia manages the platform from its Berlin headquarters, operating across the DACH region, the Nordics, and the broader European Union. The team size is not publicly disclosed. The dual-track model — direct venture capital and climate fund-of-funds — remains rare in Europe, where most climate platforms choose one path. Extantia's decision to pursue both creates a structural advantage in manager sourcing, though it also demands that the partnership allocate talent and time across two distinct investment processes. What distinguishes Extantia Allstars from a conventional climate fund-of-funds is the embedded direct investment capability. The same partnership that selects outside managers also deploys capital directly into companies, avoiding the agency problem that separates traditional LPs from the underlying assets. The governance sits with the founding partners, who maintain authority over both the fund-of-funds allocation and the direct portfolio, aligning incentives across the entire platform.
