Socii Capital

Socii Capital is a venture capital firm that makes lead investments in growth-stage businesses, with a stated focus on next-generation digital infrastructure companies. Its areas of interest span software, data and healthcare, and more specifically fintech, supply chain, digital infrastructure, urban planning and transportation, automation, autonomous vehicles, fraud and anti-money-laundering detection, payroll data, legal research, consumer finance and biopharmaceuticals. The firm partners with mission-driven entrepreneurs and positions itself as a lead investor at growth stage rather than a passive participant in syndicates.

The investment approach is deliberately concentrated: Socii Capital plans 12 or fewer lead investments, prioritising depth of engagement over portfolio breadth. That concentration is reflected in its record and its relationships with founders - 33% of its legacy portfolio has exited, and every growth-stage founder in the portfolio is now a limited partner in the firm. The structure places founders alongside the firm as LPs, aligning economic interests across successive investments.

Socii Capital operates from San Francisco, California and London, UK. Socii Capital LLP is authorised and regulated by the UK Financial Conduct Authority.
