What We Do

The American public sector is the world’s largest addressable market.

However, barriers to entry are high, favoring large scale operators. Barnaby Street provides portfolio companies with a headstart advantage, offering founders a platform for expediting market entry, sales, customer retention, and competitive advantage.

Barnaby Street is a hands-on, action-oriented investor focused on generating fundamental market value through a combination of capital and strategic support. Our investment model integrates targeted liquidity with a suite of go-to-market services designed to accelerate growth for portfolio companies.

Our Team

Barnaby Street was founded by a group of longtime friends and trusted colleagues who built distinguished careers as C-suite leaders, partners, and senior executives. After decades of navigating complex markets, scaling companies, leading large government agencies, and investing across industries, we came together to build a different kind of venture firm—one grounded in real operating experience.

We exist to bring together our collective successes, hard-earned lessons, and multidisciplinary expertise in service of a new generation of market makers. Our primary focus is early-stage technology companies—helping them achieve product-market traction and build the revenue foundation necessary to attract sustained investment. We work alongside founders to accelerate commercialization, sharpen go-to-market strategy, and convert early momentum into scalable growth.

We specialize in selling into government and core public-interest sectors, including healthcare, transportation, banking, education, legal services, and utilities. These industries are essential, highly regulated, and often underserved by modern innovation—yet they represent some of the largest and most durable markets in the world.

We are committed to bringing the best and brightest emerging talent to public- sector challenges, championing disruptive technologies that can be deployed quickly, implemented affordably, and deliver exceptional ROI for both customers and investors.
