Mosaik Partners

Investment decisions are made by managing partners Miles Kilburn and Howard Mergelkamp alongside partners John Katzenmeyer and Eric Varney. The team combines operating, investment banking, and corporate law experience within financial technology, with each senior professional having spent decades in the sector before joining Mosaik.

Mosaik Partners is a private equity firm, not a family office. It was founded in 2013 as an independent asset manager and raises outside capital to invest in early-stage business-to-business fintech companies, with no disclosed connection to a single-family wealth source.

Mosaik's typical entry point is late seed and Series A rounds, targeting companies that have achieved or are close to achieving commercial traction. The firm reserves capital for follow-on investments in every portfolio company and takes a hands-on approach to governance.

The firm invests exclusively in enterprise financial technology. Its named sector focus areas include payments, capital markets technology, regulatory technology, big data and AI applied to financial services, financial SaaS, and bank technology. It has a stated preference for transactional and software-based revenue models.

Mosaik regularly participates in syndicated rounds. Its March 2026 follow-on investment in Sigma360's $17.3 million Series B joined a syndicate led by Moderne Ventures and included Vocap Partners, Orrick, and Contour Ventures. The firm also invested in MagicCube alongside e& capital.

Mosaik's deal flow derives from the practitioner networks of its partners, all of whom spent their prior careers in financial technology as operators, advisors, and investment bankers. The firm describes its sourcing model as relationship-driven, targeting experienced founders who are solving infrastructure friction points in business-to-business finance.

Mosaik is headquartered in San Francisco and invests predominantly in North American companies, but its portfolio companies serve global financial institutions. MagicCube's 2026 round included UAE-based e& capital, extending the firm's indirect exposure to Middle Eastern digital identity infrastructure.
