Cross Bay Ventures

Cross Bay Ventures is a New York-based venture capital firm focused on early-stage B2B software and fintech companies. Founded by Mark B. Lazer and a team of former operators, Cross Bay has built a reputation for backing technical founders building essential infrastructure for financial services and enterprise operations.

What sets Cross Bay apart is their operator-first approach to venture investing. Unlike firms where partners come from finance backgrounds, Cross Bay's team includes former CTOs, product leaders, and founders who have actually built and scaled B2B companies. This operational depth means founders get genuine technical mentorship, not just capital.

The firm typically invests $250K to $5M in pre-seed through Series A rounds, with a focus on companies building foundational fintech infrastructure, B2B payments, and enterprise productivity tools. Cross Bay prefers to lead rounds and takes an active role in helping portfolio companies navigate technical and go-to-market challenges.

Cross Bay has developed particular expertise in fintech, with multiple portfolio companies building payment infrastructure, lending technology, and financial data platforms. This specialization has created a flywheel where fintech founders seek Cross Bay for their domain expertise.

For founders building in fintech or B2B software, Cross Bay Ventures offers a partner who has walked in their shoes—someone who can help navigate technical architecture decisions and enterprise sales simultaneously.

Cross Bay Ventures maintains a clear investment thesis focused on identifying and supporting exceptional technical founders building essential B2B infrastructure. The firm's approach combines rigorous market evaluation with genuine technical due diligence.
