Arch, a private investment management platform modernizing K-1 workflows, automating operations and simplifying reporting for financial professionals, today announced that it has raised $20 million in Series A funding. This round was led by Menlo Ventures, with participation from existing investors Craft Ventures and Quiet Capital, as well as new investors Carta, Citi Ventures, GPS Investment Partners and Focus Financial Partners. Arch plans to use the new capital to expand its team and enhance its product, with a focus on streamlining the repetitive manual work traditionally associated with investing in and managing alternative investments.

The founders of Aduro Advisors, Altruist, Equi, Sydecar and Vanilla also invested, along with industry thought leaders Gary Cohn, Scott Prince and Marc Spilker. They were joined by members of Arch's client base that includes single- and multi-family offices and wealth management firms.
