Perkins Cove Partners

Founder Sean Marshall leads investment decisions, supported by operating partners Lou Orfanos and Steve Wietrecki. All three come from senior operating roles at enterprise-software companies including Klaviyo, HubSpot, and Toast. The firm describes the group as a cross-functional team of executives who invest their own capital and time directly into portfolio companies.

The firm writes initial checks ranging from $100,000 to $500,000 or more, targeting pre-seed and seed-stage B2B SaaS companies. Perkins Cove states a preference for being the first or one of the first institutional investors in a company. It concentrates capital into a small number of opportunities rather than running a high-volume seed portfolio.

Sean Marshall previously served as a scout for Craft Ventures, focused on pre-seed B2B SaaS investments, building a sourcing network within that ecosystem. The broader team's ongoing executive roles and advisory relationships at growth-stage software companies generate additional deal flow. The firm's website also captures inbound interest through a subscription form for periodic updates.

No separate fund structure is publicly disclosed. The firm appears to operate on a principal-capital basis, with the three named partners investing their own capital directly. This operator-syndicate model avoids the deployment timelines and LP-relationship overhead of a conventional venture fund.

The firm's three partners work as hands-on operating partners across go-to-market strategy, product-market-fit refinement, business operations, fundraising readiness, and hiring. The team collectively has experience scaling companies such as Klaviyo, HubSpot, Toast, Yammer, and SuccessFactors, and they describe their model as embedding themselves as extensions of the founding team.

The firm focuses on B2B SaaS — specifically enterprise software companies. No other sectors appear in its public materials. The partners' operating backgrounds are concentrated in CRM, marketing automation, restaurant technology, and collaboration software, which aligns with this narrow focus.

Perkins Cove is an independent entity, not a corporate venture capital arm of Klaviyo, Toast, or any other firm where the partners previously worked. Sean Marshall founded the firm separately after departing Klaviyo, and the capital deployed is the partners' own, not a strategic initiative of their former companies.
