North Forty Ventures

North Forty Ventures targets early-stage companies in enterprise software, AI/ML, industrial technology, digital health, climate technology, and fintech. The firm writes first-check capital, typically at pre-seed through Series A stages, with a geographic emphasis on the Pacific Northwest — particularly founders emerging from Amazon and Microsoft. This concentration reflects a structural view that the region's hyperscalers produce technical talent and entrepreneurial density that is underserved by coastal venture capital.

The firm's sourcing model relies on embedded relationships within Seattle's Amazon and Microsoft engineering communities. By maintaining proximity to the senior technical talent departing these companies, North Forty Ventures accesses deal flow that often receives full subscription from local investors before broader institutional marketing begins. This network-based approach creates an information advantage that coastal funds struggle to replicate, particularly for companies founded by domain experts in cloud infrastructure and developer tools.

North Forty Ventures writes initial checks ranging from approximately $500,000 to $2 million and maintains reserve capital for follow-on investments through subsequent rounds. The firm's public record does not disclose whether it typically leads or participates as a co-investor, though its early-stage positioning and concentrated regional focus suggest a willingness to lead or co-lead seed rounds where local relationships provide diligence advantages. Allocators should confirm round leadership posture directly with the firm.

The firm has not publicly disclosed its fund structure, fund sizes, or limited-partner composition. North Forty Ventures maintains a deliberately low public profile, consistent with a boutique manager that prioritizes founder relationships over institutional marketing. This opacity means prospective co-investors or limited partners must rely on direct diligence to understand vehicle terms, management company economics, and LP concentration risk.

North Forty Ventures occupies a specific niche within Seattle's venture landscape — earlier-stage, more technically focused, and less institutionally visible than larger peers like Madrona Venture Group or Frazier Healthcare. Its deliberate absence from major venture databases and limited media presence suggest a strategy optimized for sourcing proprietary deal flow rather than building a public brand. For allocators, this implies a manager whose alpha generation depends almost entirely on local network quality rather than platform scale.
