Maybern
Maybern is a New York-based fintech building the operating system for private fund finance. Its platform unifies fund accounting, waterfall and fee calculations, capital calls, distributions, and LP reporting into a single 'Performance Book of Record', replacing the spreadsheet sprawl that has long defined the back office of private equity, private credit, and real estate funds. Founded by former Cadre engineers Ross Mechanic and Ashwin Raghu, the company raised a $50M Series B led by Battery Ventures in November 2025 and supports over $80 billion in assets under management.
