A former real estate investment platform founder has secured $10 million to attack a new frontier: the chaotic back-office operations haunting private credit firms. Ryan Williams, who previously built Cadre into an $800 million company, revealed Thursday that his artificial intelligence startup Ellis has closed a seed round and exited stealth mode.
The funding round drew backing from heavyweight investors including First Round Capital, 645 Ventures, Harlem Capital, Khosla Ventures, Thrive Capital, Slow Capital, and Ariel Alternatives CEO Mellody Hobson. Williams launched the venture last year after spotting a persistent problem during his Cadre tenure.
While the visible side of private markets underwent a modernization wave, the machinery underneath remained stuck in the past. Spreadsheets, disconnected accounting tools, and document silos still dominate the daily workflow for many credit managers. Ellis deploys AI agents specifically designed to stitch these fragments together into a single, coherent platform.
The system plugs directly into software and documents a firm already uses. Rather than forcing organizations to abandon existing tools and rebuild from scratch, Ellis layers on top, centralizing information without the costly disruption of a full overhaul. Its agents can scan for data inconsistencies, monitor portfolios, prepare reports, and even close a fund’s books at month-end.
Williams described how many teams currently download files from multiple systems, manually reformat everything, cross-check balances, and re-enter numbers by hand. In that environment, he noted, Excel effectively becomes the operating system. Ellis aims to replace that drudgery with automation.
A human remains firmly in control. Williams stressed that consequential decisions stay with the experts. When pressed about the prospect of fully autonomous AI, he acknowledged the loop will likely shrink over time but won’t vanish. The core mission centers on accelerating judgment, not replacing it, by filtering out noise so that professionals can make sharper calls faster.
As private credit continues its explosive growth, the operational headaches that Ellis targets have become impossible to ignore. Williams bets that firms ready to modernize their backend without uprooting their entire tech stack will fuel demand for a smarter connective layer.
