“Can an AI-native ERP replace legacy general ledger software (NetSuite, QuickBooks) for high-growth SaaS companies by automating the entire accounting workflow through deep native integrations?”
Founded in 2021 by Nicolas Kopp (former U.S. CEO of N26), Rillet set out to replace legacy ERP general ledger software with an AI-native accounting platform purpose-built for high-growth SaaS companies. Rather than layering AI onto an existing system, Rillet rebuilt the general ledger from scratch with native integrations to the modern finance stack (CRM, billing, AP, payroll, tax, banks). In 2025, rapid back-to-back funding rounds from Sequoia, a16z, and Iconiq signaled market conviction that AI could finally displace incumbents like NetSuite and QuickBooks for tech-forward CFO teams. The Ernst & Young alliance further positions Rillet as an enterprise-grade solution rather than a pure SMB product.
