Stormbreaker Ventures

Stormbreaker Ventures, based in San Francisco, California, is an early-stage venture fund established in January 2021. The firm positions itself as a partner to founders, aiming to support them through their entrepreneurial journey. True to its stated focus, Stormbreaker primarily targets pre-seed and seed-stage companies, investing in ambitious founders who are building the future. Their investment philosophy appears to be hands-on, emphasizing support beyond just capital.

The firm's portfolio, as evidenced by public data, includes a diverse set of early-stage companies across various sectors. For instance, Stormbreaker Ventures participated in the $3.5 million seed round for Replicate, a company focused on AI model deployment, and also contributed to the $1.5 million pre-seed round for Rivet, a platform designed for software development. While their core mandate is early-stage, the firm has also shown a willingness to participate in later-stage rounds, such as Series C and D investments in companies like Lark Health and The Athletic, likely as follow-on support for their portfolio companies or strategic co-investments.

Given its early-stage focus and the typical sizes of the rounds it participates in, Stormbreaker Ventures generally writes initial checks ranging from approximately $100,000 to $500,000. These investments are typically part of larger syndicated rounds, where Stormbreaker contributes alongside other venture firms and angel investors. The fund's relatively recent inception in 2021 and its growing portfolio of over 10 publicly disclosed investments underscore its active presence in the early-stage venture ecosystem.
