Non-sponsored businesses, Founder-driven growth, LP-proven performance.
Who We Are
Founded in 2008, Metropolitan Partners Group (Met) is a New York–based private investment firm. We provide non-controlling growth capital to non-sponsored, entrepreneur-led businesses predominantly across the U.S., designed to preserve ownership, honor the management team’s vision, and accelerate scale.
By the Numbers
The Non-Sponsored Advantage
Why non-sponsored matters —
For Owner-Operators
You built your business from the ground up and understand your market better than anyone. Non-sponsored means you maintain control and that entrepreneurial edge - partnering with Metropolitan provides the bespoke growth capital and operational expertise to accelerate your vision.
For Investors
Non-sponsored businesses often represent untapped alpha opportunities—companies built on genuine market needs with proven business models, led by founders with skin in the game and deep operational knowledge.
Beyond Capital
Our multidimensional Operating Network & Ecosystem (ONE) connects you with 600+ experienced operators and ecosystem partners across key business functions and service needs. Real expertise from people who’ve built, scaled, and optimized businesses—not textbook solutions.
