Maybern builds fund-management infrastructure that unifies fund, investor, and investment data into a single performance book of record. Its cloud platform replaces spreadsheets and manual workflows with automated controls, real-time analytics, and governance tools, enabling CFOs to shift from reactive reporting to strategic insight generation. Over the past year the company recorded 4.6× year-over-year growth and now supports more than $80 billion in assets under management across clients such as Madison Realty Capital, Gauge Capital, Town Lane, and Derby Lane Partners. Maybern positions its software as the data foundation that makes AI reliable for private-markets workflows. With the new financing, the company will expand R&D and roll out additional AI-driven tools to further automate fund operations, streamline audits, and enhance reporting. Founded in New York City, Maybern has raised $76 million in total funding to date.
