When Nicolas Kopp led German digital bank N26‘s U.S. operations, he learned that world-class finance teams were often slowed by outdated systems, forcing them to wait weeks for critical metrics despite working at high speed. That frustration planted the seed for Rillet, an AI-native enterprise resource planning platform built by accountants to modernize how companies handle their books.
Now, Rillet said it secured $70 million in Series B funding co-led by Andreessen Horowitz and ICONIQ, bringing total funding to over $100 million in less than a year.

The $70 million raise includes participation from Sequoia, Oak HC/FT, and earlier investors, arriving just 10 weeks after Rillet’s $25 million Series A. The company said the funding will accelerate Rillet’s push to rebuild enterprise accounting from the ground up, giving finance leaders the ability to scale multi-billion-dollar companies with smaller, more efficient teams.
As part of the round, Andreessen Horowitz General Partner Alex Rampell and ICONIQ General Partner Seth Pierrepont are joining Rillet’s board of directors.
“Finance teams deserve the same AI advantages that have revolutionized sales, engineering, and legal,” Rampell said in the company’s statement, while Pierrepont noted that the company’s AI-native approach “can give companies a clear edge: faster insights, leaner teams, and smarter decisions.”

Founded by Kopp and Stelios Modes, the technical architect who built N26’s payment infrastructure, Rillet was designed to eliminate the inefficiencies of legacy systems owned by large incumbents such as Oracle (NYSE:ORCL), Sage, and Microsoft (NASDAQ:MSFT). The company’s leadership team includes former executives and accountants from EY, PwC, and other major firms, embedding industry expertise into every workflow.
Rillet has signed more than 200 customers since launch, doubling its annual recurring revenue over the last 12 weeks and forming partnerships with top accounting firms like Armanino and Wiss. Clients such as Postscript, which generates over $100 million in annual recurring revenue, close their books in just three days using Rillet, while Windsurf manages its entire finance operation with a team of two people.
