Background

Greg Sands is the Founder and Managing Partner of Costanoa Ventures, an early-stage venture capital firm based in Palo Alto, California, which he launched in December 2012 with a $100 million fund 12. He holds a B.A. in Government from Harvard College and an M.B.A. from Stanford Graduate School of Business 3.

Before founding Costanoa, Sands was a Managing Director at Sutter Hill Ventures from September 1998 through December 2011, where he focused on early-stage enterprise technology investments including Merced Systems, AllBusiness, QuinStreet, FeedBurner, and Youku 34. He left Sutter Hill by negotiating a two-page agreement that allowed him to take portions of stakes in companies he had led as seed capital for Costanoa 5.

Earlier in his career, Sands was the first non-engineering hire at Netscape Communications in 1994, where he served as the company’s first Product Manager, wrote the initial business plan, and coined the name “Netscape” 46. He created and led the SuiteSpot Business Unit, growing it from zero to $140 million in revenue 4. The company went public 14 months after his start with an $8 billion market cap 6. He also served as Manager of Business Development at Cisco, where he architected a global channel management plan 4. Before entering technology, Sands worked at Mercer Management Consulting 3.

Sands serves as Senior Advisor to the Chairman at QuinStreet and was a member of its board of directors from July 1999 through October 2020 3.

Stated Thesis

Costanoa publicly describes its focus as backing “incredible founders building extraordinary companies that can solve big problems” at the seed and Series A stage 7. The firm positions itself as an “early-stage missing middle investor” between angel investors and larger lifecycle venture firms, taking concentrated 10-15%+ stakes in approximately 35 companies per fund with substantial hands-on support 8.

Sands has stated the firm’s current focus areas are AI-enabled SaaS, AI and data infrastructure, cybersecurity and national security, and fintech 7. He has described the firm’s approach as: “At Costanoa, we are not chasing momentum, but trying to create it” by identifying underserved sectors before saturation occurs 2.

On his personal investment philosophy, Sands has stated: “Our job is fundamentally to find extraordinary entrepreneurs working on important problems and then make an investment and support them” 9. He emphasizes a product-manager-like approach, personally going on sales calls with founders to assess product-market fit 510.

Inferred Thesis

Based on 27 verified investments below, the following patterns emerge. Note: this represents a fraction of Costanoa’s 218+ total investments 11; the analysis reflects Greg Sands’ personal investment activity where attribution is publicly confirmed.

Sector distribution (27 verified investments): Enterprise software/SaaS dominates with 10 of 27 investments (37%), followed by cybersecurity/security at 5 of 27 (19%), fintech at 4 of 27 (15%), data/analytics at 4 of 27 (15%), AI/ML applications at 3 of 27 (11%), and defense/national security at 1 of 27 (4%). Several companies span multiple categories.

Stage distribution: Predominantly seed and Series A investments. The firm’s check size ranges from $500,000 to $5 million with a sweet spot around $3.5 million 812. Fund V ($275 million, closed September 2024) targets approximately 35 companies with 10-15%+ ownership 710.

Geographic focus: Investments are concentrated in the San Francisco Bay Area and broader U.S. market, with occasional international investments (Aquabyte in Norway, Tensec with offices in Mexico City and Sao Paulo).

Notable exits pattern: Multiple nine-figure exits including Intacct (acquired by Sage for ~$850 million) 4, Roadster (acquired by CDK Global for $360 million in 2021) 13, Kenna Security (acquired by Cisco in 2021) 14, and VictorOps (acquired by Splunk in 2018) 15. Datalogix was acquired by Oracle 4. This pattern suggests a preference for category-defining B2B companies that become acquisition targets for large platform companies.

Founder profile patterns: Sands explicitly prioritizes people above product, market, and price at the seed stage 10. He looks for drive and tenacity, intellectual curiosity, and system-building ability in founders 6. Multiple portfolio companies were co-founded by repeat entrepreneurs.

Co-investor patterns: Frequent co-investors include DCVC, Fika Ventures, Uncork Capital, and Khosla Ventures based on verified rounds.

Notable gap: Despite the firm’s stated emphasis on fintech and AI, the verified portfolio shows enterprise SaaS and cybersecurity as the strongest categories by exit value. The defense tech focus appears to be a newer expansion driven primarily by partner John Cowgill rather than Sands personally 7.
