Vol. 1 Ventures

Managing Partner Sean Cantwell leads all investment decisions. He founded the firm in 2021 after ten years at Volition Capital, where he sourced growth-equity deals in software and technology. Cantwell works with a small team of venture partners who bring operating experience to diligence and portfolio support.

Vol. 1 Ventures operates as an independent seed-stage firm, but it has a structured partnership with Volition Capital. Companies that graduate from Vol. 1's seed portfolio and reach Series B stage have a direct path to growth financing from Volition's funds. This arrangement gives seed founders continuity of sponsor without re-shopping a new lead investor.

Vol. 1 writes initial checks between $500,000 and $2 million, typically leading or co-leading pre-seed and seed rounds. The firm reserves significant follow-on capital to maintain its ownership position through subsequent financing rounds. Portfolio companies have averaged one to two follow-on investments each.

Vol. 1 has not made investments in hardware-intensive businesses, biotech, or consumer packaged goods. The partnership's edge lies in enterprise-facing models with recurring revenue characteristics—a discipline carried over from Cantwell's growth-equity background. The firm also stays away from capital-intensive infrastructure plays.

Sean Cantwell sources a substantial portion of Vol. 1's pipeline through the alumni network of Volition Capital and through his own decade-long relationships with operators and founders in Boston and San Francisco. The firm does not rely on a scout program or an advisor network, preferring direct founder referrals and repeat entrepreneurs who previously worked with Cantwell.

Vol. 1 Ventures invests exclusively through direct equity positions in startups. The firm does not commit capital to external venture funds, nor does it operate as a fund of funds. All capital is deployed into individual portfolio companies at the pre-seed and seed stages.

Vol. 1 maintains an active pro-rata strategy through Series B rounds. The firm's partnership with Volition Capital means that companies reaching growth-stage metrics can receive expansion checks from Volition's dedicated growth funds—effectively giving Vol. 1 portfolio founders a single-relationship bridge from formation to scale.
