Rillet Raises $25M Series A to Disrupt the Accounting Software Space

Welcome back to The SaaS CFO Podcast! In today’s episode, we’re diving deep into the next generation of accounting software with Nicolas Kopp, CEO and founder of Rillet. Nicolas shares his journey from building a fully regulated bank to launching Rillet—an AI-first ERP platform designed to take on industry staples like QuickBooks, Xero, NetSuite, and Sage Intacct. With a background grounded in finance and accounting, Nicolas brings a fresh perspective to a market that’s long been dominated by legacy solutions.

We’ll discuss how Rillet is shaking things up for asset-light businesses in SaaS, AI, professional services, and fintech, and why the platform’s robust multi-entity, multi-currency capabilities have attracted mid-market companies ready to graduate from more traditional tools. Nicolas also sheds light on the challenges of building highly regulated, mission-critical systems from scratch, what’s behind their rapid customer adoption, and how an AI-native approach is changing expectations for accounting software.

From funding milestones and his recent $25 million Series A, to lessons learned about product-market fit and the nuances of scaling go-to-market through channels and inbound demand, Nicolas gives us the behind-the-scenes look at Rillet’s rise. If you’re curious about the future of financial software—or when it’s really time to make the leap from QuickBooks to a next-gen ERP—this conversation is for you. Let’s get started!
