Seabird Ventures

What Seabird Ventures does

Seabird Ventures is an early-stage venture capital fund investing from Pre-Seed through Series A into ocean and climate technology startups. The fund targets six verticals — maritime decarbonization, minerals and chemicals, circular economy, ocean data, aquaculture tech, and coastal resilience — with a disclosed portfolio of 17 companies operating across 45+ countries and creating 1,000+ jobs, of which 60% are female-founded.

Seabird operates as the affiliated venture fund of the Sustainable Ocean Alliance (SOA), a 501(c)(3) nonprofit. This relationship provides proprietary deal flow from the SOA Ecopreneur Network spanning 165+ countries, alongside access to a 700+ investor co-investment pool and 360+ mentors that support portfolio companies with technical advice, investor introductions, and follow-on capital. A portion of Seabird's carried interest is returned to SOA to fund the next generation of ocean leadership and the Ecopreneur Network itself, operating as a venture-philanthropy hybrid rather than a conventional for-profit VC.

The fund is managed by a small team of 1–10 headquartered in San Francisco. The investment committee is chaired by Matthew Mulrennan (Head of Investments) and includes Anne Park (SOA CEO) and Kim Kolt, with Alicia Hernandez Arriaga leading investment and impact diligence. Seabird generates returns through standard VC fund mechanics — management fees on committed capital and carried interest on portfolio exits — with deal sourcing concentrated through the SOA network rather than outbound sales. The firm has been recognized as an ImpactAssets 50 Emerging Manager three times (2023, 2025, 2026).
