03Research

Rillet is the most technically ambitious of the AI-native US ledgers. It's explicitly an ERP — not just a bookkeeping tool — targeting hyper-growth SaaS with multi-entity consolidation, advanced ASC 606 revenue recognition, intercompany eliminations, and native usage-based billing. The August 2025 $70M Series B led by a16z and ICONIQ (just ~10 weeks after a $25M Sequoia-led Series A) took total raised past $100M at a reported ~$500M valuation, with named customers including Mercor, Windsurf, and Function Health.

The 2026 integrations story has become a real moat: the BILL × Rillet native two-way integration shipped in March 2026, and Zapier × Rillet opened an 8,000-app surface in the same month. For a post-Series-B SaaS company that's outgrown QuickBooks and isn't ready for NetSuite, Rillet is increasingly the default answer.

Price is the main limiter. Rillet isn't for companies with fewer than a dozen people in finance; it's for companies with a finance-and-accounting team that needs a purpose-built tool. The live duopoly is against Campfire, which has sharper revrec-first positioning and a similarly accelerating capital base.
