Ark

Ark is a Boston-based software company that builds a cloud platform for running private capital funds. Founded in 2017, it combines fund accounting, an investor portal, LP reporting, and fundraising tools into one system used by venture capital, private equity, fund-of-funds, and real estate managers as well as the fund administrators who service them. By 2026 the platform supported more than 500 GPs and administrators overseeing roughly $185 billion in assets. In July 2026, AngelList acquired Ark to fold its fund-administration software into AngelList's banking, payments, and cap-table infrastructure.
