“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.
Rillet uses Tipalti for FX and cross-border payouts.
Rillet's payroll is powered by Finch.
Rillet integrates with Stripe, Salesforce, Brex, BILL, Tipalti, Anrok and Avalara.
The Embedded Finance Index 2026 maps 6 layers in Rillet's stack: Payroll (Finch); Unified APIs (Apideck and Finch); FX & payouts (Tipalti); Accounting (Stripe, Salesforce, Brex, BILL and 3 others); Spend / AP (Brex and BILL); Treasury (Brex Treasury and Atlar).
Rillet was founded by Nicolas Kopp and is founded in 2021, headquartered in Palo Alto, CA (also New York, NY).
Rillet has raised $108.5M+ in total (latest round: Series B, 2025; valuation: ~$500M post-money (2025)).
