Sumeru Equity Partners has led a $175 million growth investment in K1x, a Morristown, New Jersey-based private markets tax data platform. The deal positions Sumeru as the majority shareholder, with existing investor Edison Partners also participating through its third investment in the company since 2022.

K1x provides tax data management solutions for private market investors, addressing the complex reporting requirements that arise from alternative investments. John LaMancuso serves as CEO of the company, which has attracted significant capital as demand grows for specialized financial technology in the private markets space. The investment comes amid increased institutional interest in private equity and alternative assets.

The funding round reflects confidence in K1x's ability to scale its platform and capture market share in the growing tax data management sector. With Sumeru's majority stake and Edison's continued support, K1x appears positioned to expand its product offerings and potentially pursue strategic acquisitions to strengthen its market position.
