About US

We are deeply committed to preserving the legacy, culture, and relationships you've built, and we’ll ensure the business continues to thrive with integrity and care.

Derby Street Partners is a husband-and-wife-led search fund focused on acquiring, growing, and leading an exceptional business.
Named after the street where we first met, Derby Street symbolizes our shared vision and commitment to building something meaningful.
We are not a private equity firm. Leveraging the “Search Fund” model, we aim to bring a new perspective, operational expertise, and a firm commitment to building the legacy of the business we acquire.
We see the heart and dedication you've poured into this business, and we're committed to honoring that by leading with integrity, nurturing trust, and building on the strong foundation you’ve created.
Rooted in lessons from our immigrant entrepreneurial families, we value and practice hard work, resilience, and dedication—principles that guide our approach to entrepreneurship and business leadership. At Derby Street Partners, we believe the American Dream is alive, and we are living proof of its potential as we continue to pursue it.
