Costanoa Ventures

Costanoa Ventures Research Document Investment Thesis Costanoa Ventures is an early-stage venture capital firm founded on the belief that building transformational companies requires more than capital—it demands deep operational expertise, consistent partnership, and genuine commitment to founders' success. The firm backs visionaries solving big, hard problems across data infrastructure, applied AI, cybersecurity, fintech, and emerging security domains. Founded in 2012 by Greg Sands (former Managing Director at legendary Sutter Hill Ventures and first product manager at Netscape), Costanoa brings decades of operational experience to early-stage investing. Sands' background—having written Netscape's initial business plan, coined the company name, and built SuiteSpot from $0 to $140M—deeply informs the firm's approach to supporting founders through every phase of company building. The core thesis centers on the "missing middle" of early-stage investing: providing unusually intensive, hands-on support to founder teams during their most critical growth phases. Costanoa believes that the best guidance is hard-earned and shared humbly, taking a long-term partnership view that extends far beyond the initial term sheet. Investment Stage & Check Size Costanoa leads investments from formation through Series A: Pre-Seed/Formation : Supporting founders from Day One with initial capital Seed : $1M-$5M (building product-market fit, early customer traction) Series A : $5M-$10M+ (scaling proven concepts, expanding go-to-market) Typical check size range: $2M-$5M for early-stage deployment. Lead tendency: Strong tendency to lead rounds, with proven follow-on commitment through Opportunity Funds for exceptional portfolio companies. Stage Preferences & Investment Approach Costanoa explicitly focuses on: Seed-stage founders with vision and early product traction Series A companies with proven product-market fit ready to scale Concentrated stakes (10-15%+ ownership target, indicating deep commitment) The firm targets fewer, larger investments per fund than typical early-stage VCs—approximately 35-40 companies across the portfolio. This "boutique by design" approach enables the firm to provide the operational depth and partnership intensity Costanoa believes transforms early-stage companies into enduring market leaders. Sector & Model Focus Primary Sectors: AI & Data Infrastructure, Applied AI / SaaS, Cybersecurity, National Security, Fintech, Enterprise Software, Developer Tools & Infrastructure Investment Focus Areas (2025-2026): Applied AI with real enterprise/operational use cases AI infrastructure and model deployment systems Cybersecurity automation and zero-trust architectures Regulatory automation (SOX testing, compliance) Fintech and cross-border payments innovation Therapeutic/healthcare AI applications Infrastructure for emergent AI workforce automation Model Preferences: B2B SaaS targeting enterprise customers, Developer tools and infrastructure solving tangible pain points, Vertical software applications in specialized domains, Infrastructure powering AI/ML at scale The firm shows particular enthusiasm for founders building tools that solve real problems for knowledge workers and technical teams, with recent investments spanning regulatory compliance (Midship - SOX automation), legal AI (Ivo), API security (StackHawk), satellite data infrastructure (Muon Spaces), and healthcare innovation (Marble Health).

Lead Tendency & Investment Philosophy Lead Tendency: Strong lead investor in seed rounds, co-lead/participant in series A expansion rounds. The firm's philosophy emphasizes conviction and early commitment ("show up early, commit with conviction"), resulting in: Leading seed rounds for new investments, Deep follow-on reserves (50%+ of fund) for exceptional portfolio companies, Multi-stage partnership through Series B+ for winners, Monthly board involvement indicating seat-taking and operational commitment. Founder testimonials consistently emphasize that Costanoa engagement increases post-investment rather than decreasing. As Alation CEO Satyen Sangani states: "I think of Greg as a co-founder. Every time I needed input, he's been my first call."
