M33 Growth Overview
M33 Growth is a private equity firm located in Boston, Massachusetts founded in 2017 by Brian Shortsleeve, Gabe Ling, and Mike Anello.
M33 Growth derived its name from Mach 33, the speed at which an object hits escape velocity and breaks free from the gravitational pull of the Earth.
Their name mirrors the firm’s approach: supporting ambitious bootstrapped founders and CEOs through capital funding and providing resources to propel growth and transform their already-great businesses into market leaders.
They accelerate the growth of their portfolio companies by:
- Applying experience in boosting sales and marketing engines
- Driving strategic acquisitions
- Building value through the creation of data assets
While many firms only provide capital, M33 Growth prides itself for bringing a differentiated hands-on experience to the entrepreneurs they partner with.
