Social Impact Capital

Founder and Managing Partner Sarah Cone is the sole General Partner and makes all investment decisions. She is supported by a network of 40 Venture Partners who contribute to sourcing, due diligence, and portfolio support, but the firm does not operate with an investment committee beyond Cone herself.

The firm employs a research-driven approach, using data analysis to identify the 'best ideas in impact' before founders are on the radar of larger firms. It leverages its 40-person Venture Partner network — which includes repeat founders, subject-matter experts, and former portfolio company executives — to surface and diligence opportunities across climate, health, and AI sectors.

Social Impact Capital is structured as a venture capital firm, not a family office. It raises external capital from limited partners, including Peter Thiel, and manages commingled funds rather than a single-family balance sheet. It is helmed by a solo General Partner, Sarah Cone.

The firm invests at the earliest possible stages — typically pre-seed and seed — and aims to be the first institutional capital into a company. It supports founders until they are positioned for Series A and later rounds led by top-tier venture firms. Fund I reports a 69% rate of follow-on investment by top-tier firms.

Peter Thiel is a disclosed limited partner in Fund I. The firm also cites relationships with general partners at Andreessen Horowitz and DCVC, including Peter Levine and Jason Pontin, who have served in the firm's Venture Partner network or commented on its work, though it does not disclose a full LP list.

The firm focuses on global challenges it can address through venture-scale technology, explicitly citing climate crisis solutions, novel therapeutics, and food system resilience. It avoids what it describes as 'backyard problems' and consumer internet software, instead concentrating on deep tech, bio, and industrial transformation.

The firm operates with a single General Partner, Sarah Cone, and a decentralized network of 40 Venture Partners. These Venture Partners are not employees but a global group of operators, founders, and investors who assist with sourcing, due diligence, and portfolio company support. The model is designed to provide broad expertise without the management layers of a traditional multi-partner firm.
