Senior Associate - Enterprise

Our Company

Arch is a Series B financial technology company that automates the management of private investments, improving access, understanding, and the human experience of investing across asset classes.

Private investments such as venture capital, hedge funds, and private equity, make up roughly 25% of the investment universe. Traditionally, investors, advisors, banks, families, and managers track hundreds of investments in complicated spreadsheets, file folders, and busy inboxes. Not only is this tedious and time‑consuming, but it is rife with opportunity for manual data entry errors, inconsistent reporting, and lost information.

Enter, Arch.

Our purpose is to save investors’ time while empowering them to make more informed investment decisions, leading to better financial outcomes.
