AI-Native ERP Rillet Raises $70 Million in Series B

Rillet, an AI-powered ERP platform led by Nicolas Kopp (CEO & Co-Founder) and Stelios Modes (CTO & Co-Founder), has raised $70 million in Series B funding, co-led by Andreessen Horowitz and ICONIQ, with participation from Sequoia, Oak HC/FT, and earlier investors. Andreessen Horowitz General Partner Alex Rampell and ICONIQ General Partner Seth Pierrepont are joining the board.

Just 10 weeks after its $25M Series A from Sequoia, Rillet has now raised over $100M in under a year. With 200+ customers and ARR doubling in 12 weeks, Rillet has also partnered with top accounting firms like Armanino and Wiss. The new funding fuels its mission to reinvent enterprise accounting, enabling finance teams to scale billion-dollar companies with leaner teams.

Rillet is reinventing enterprise accounting for the modern era. In under a year, the company has raised over $100 million, doubled its ARR in just 12 weeks, and signed over 200 customers — including top firms like Postscript and Windsurf. Unlike legacy ERPs that rely on clunky workflows and bolt-on tools, Rillet is built from the ground up with AI, native integrations, and a smart general ledger that enables real-time collaboration, automation, and instant insights. In a $500B+ category dominated by slow-moving incumbents, Rillet stands out by being built by accountants, for accountants — and it's already setting a new standard for how finance teams operate at scale.

Rillet is building the AI-native financial platform for the next generation of businesses. With the accounting industry facing a looming talent shortage and 80% of financial operations ripe for automation, Rillet sits at a pivotal moment — enabling leaner teams to do more, faster. The platform doesn’t just automate; it redefines how AI and humans collaborate in finance. As customers prepare to go public on Rillet, the company is proving that modern businesses can scale from startup to IPO on intelligent, real-time infrastructure — ushering in a new era of finance.
