During that time, the Tritium team has deployed over $625 million of capital and produced several, notable “wins” for investors, founders and employees alike.The careers of Tritium’s founders began at a global management consulting firm and continued at a well-established venture capital firm, where they shared responsibility for managing several billion dollars of capital.

In 2013, Tritium Partners was launched as an independent firm that could focus exclusively on lower middle market growth buyouts.
