Funding will fuel product expansion, institutional growth, and real-time reporting capabilities for allocators NEW YORK, September 15, 2025-- Arch, the digital way to track all private market investments, today announced it has raised $52 million in Series B funding. The round was led by Oak HC/FT, with participation from Menlo Ventures, Craft Ventures, Quiet Capital and others. The funding will support Arch's ongoing expansion and development, with a particular focus on meeting the needs of institutional investors, large private wealth teams and established family offices. In an era of rapid technological advancement, private markets have emerged as the most dynamic arena in global finance. The global alternatives market is projected to reach $29.2 trillion by 2029, up from $16.8 trillion in 2023. Despite this growth and increasing investor interest, private market infrastructure is plagued by antiquated processes and massive information asymmetry. Investors must navigate hundreds of portals and thousands of emails, with little visibility or automation. In private markets, where illiquidity is inherent, the value of leverage and efficient cash management is even more pronounced. As regulatory pressure and client expectations rise, the need for real-time data, streamlined workflows and robust reporting capabilities has never been more critical. Arch is the AI-powered operating system purpose-built to eliminate the operational friction of private investing. It automatically collects and structures financial data from documents, including K-1s and statements, from various portals and emails into one secure place. New features like Arch Pay automate capital calls, making nearly every stage of alternative investing more seamless. By simplifying document collection and data extraction, Arch reduces manual administrative tasks and enhances portfolio visibility. For allocators managing complex alts exposure, Arch serves as a single source of truth, giving investors the clarity and confidence to unlock the full value of their alts business. “Investors in private markets have long been underserved – dealing with fragmented data, clunky workflows and high fees,” said Ryan Eisenman, Co-Founder and CEO of Arch. “With this new capital and the support of our partners, we're expanding our suite of CIO tools, developing new features within our client portal and enhancing reporting capabilities for LPs. We're continuing to build the product the industry needs – streamlining analysis, centralizing reporting and eliminating manual back-office work tied to alternative investments.” Over the last 14 months, Arch has grown from $100 billion to over $250 billion in private market assets on the platform. More than 50% of Arch's users have referred the platform to another client, reflecting the company's strong Realized Net Promoter Score (rNPS). Arch's key differentiator is winning and retaining the most complex clients of the firms it serves, which has fueled its expansion beyond family offices and RIAs to now serve over 450 allocators globally, including more than 100 new clients year-to-date. This growth includes four of the top private banks, seven out of the top 25 accounting firms, and some of the world's largest private wealth and institutional investment firms. All rely on Arch as their data management platform for all things alternatives. “In our diligence calls, Arch clearly stood out. We have LPs that use lots of solutions, but Arch clients showed a clear enthusiasm for the product and team that was lacking across any peer solutions. That, paired with their rollout across one of the nation's biggest banks, their traction in the institutional space, and the hundreds of family offices and RIAs that use the platform gave our team deep conviction in Arch — now and in the future,” said Matt Streisfeld, General Partner at Oak HC/FT.
