Rillet Secures $25M to Rebuild ERP for the AI Era

Rillet just landed $25 million in fresh funding to shake up a part of the software world that hasn’t kept pace with modern tech: ERP systems. The round was led by Sequoia Capital and comes less than a year after Rillet's last raise, showing how quickly the AI-native platform is gaining traction. Existing backers First Round Capital, Creandum, and Susa Ventures joined in again, along with top angel investors, including former CFOs of NetSuite and Twilio.

Traditional ERP systems, like NetSuite, were built for a different time. They’re slow, heavily manual, and often weighed down by years of customization. Rillet is aiming to wipe that slate clean with a general ledger built from scratch for the AI age. The platform plugs directly into tools like Salesforce, Stripe, Ramp, Brex, and Rippling, then uses AI agents to handle everything from accruals to reconciliation and even board reporting.

"We're a team of accountants building for accountants. This means everything from the reports to the workflows is tailor-built for the challenges CFOs and controllers deal with on a daily basis," said Rillet CEO and founder, Nicolas Kopp.

The result is a system that can help accounting teams close books in hours, not weeks. Data is fully reconciled and available in real time, allowing companies to make quicker decisions and shift focus to more strategic initiatives. That’s a big deal in an industry where waiting weeks after month-end to get a financial snapshot is still the norm.

Julien Bek from Sequoia, who led the firm’s investment, pointed out that ERP has barely changed in over a decade, mainly because rebuilding it is hard. But Rillet’s blend of domain knowledge and AI-driven design made it stand out.

Since launching in 2024, the company has grown its revenue 5x year-over-year and now processes billions in transactions. About 200 companies, including fast-scaling names like Windsurf, Decagon, and Postscript, are already using Rillet to run their accounting.

Windsurf’s VP of Finance, Adam Strouss, said the platform feels custom-made:

“Rillet feels like it was tailor-built for Windsurf and our complex accounting needs. We have a unique blend of products and revenue models and are growing at lightning speed; Rillet handles all of it effortlessly.”

This funding will help Rillet push deeper into the market and speed up the development of new AI capabilities. In related news, Sequoia’s broader fintech portfolio, which includes companies like Stripe and Block, has seen a growing push toward real-time financial infrastructure—something Rillet is clearly tapping into.
