What Rillet does

Rillet (legal entity Gnau Inc.) is an AI-native ERP platform founded in 2021 and headquartered in New York, with additional offices in San Francisco and Barcelona. The company targets mid-market companies and high-growth startups that have outgrown legacy ERPs such as QuickBooks, NetSuite, Sage Intacct, and SAP, as well as accounting firms serving those segments. Its platform centers on a perpetual general-ledger-first architecture that automates journal entries, bank reconciliations, revenue recognition (including embedded ASC 606), multi-entity consolidation, and the month-end close — explicitly designed to enable a continuous or zero-day close.

The core product is a unified ERP suite organized around the Automated General Ledger, Accounts Receivable, Accounts Payable, Bank Reconciliation, Close Management, Native Integrations (covering Stripe, Brex, BILL, Ramp, ADP, Gusto, Salesforce, HubSpot, Snowflake, Avalara, and dozens more), Flexible GAAP Reporting, Advanced Revenue Recognition, Multi-Entity Consolidation, Security and Permissions, and SaaS Reporting. Layered on top is Aura AI, a proprietary AI layer comprising workflow-specific agents, natural-language Q&A, ASC 606 contract analysis, and Aura Flow for AI-driven workflow automation. The platform is exposed through a public versioned REST API (currently v4) and an MCP server for AI-agent integration, with a developer documentation portal at docs.api.rillet.com. Rillet holds AICPA SOC certification and Avalara certification.

Rillet operates a sales-led go-to-market with quote-based subscriptions and CPA-led implementations enabling go-live in weeks. It supplements direct sales with a partner program for accounting firms (e.g., Armanino, Wiss, QueBIT), investor/VAR partners (e.g., Raiz via Pine Services Group), a strategic alliance with EY, and a community-led motion (Vibe Academy, Close Club Community). The company has raised $108.5M+ across a $13.5M round in July 2024, a $25M Series A in May 2025 (Sequoia), and a $70M Series B in August 2025 (a16z + ICONIQ) at approximately $500M post-money valuation, and reports 200-400+ customers spanning AI/SaaS, fintech, e-commerce, consumer, and traditional mid-market companies.

Core offering

Rillet sells an AI-native, general-ledger-first ERP platform that automates accounting workflows for mid-market and high-growth companies. The platform bundles a perpetual general ledger, accounts payable, accounts receivable, bank reconciliation, close management, native integrations, GAAP reporting, multi-entity consolidation, ASC 606 revenue recognition, and SaaS reporting. It is sold via subscription with CPA-led implementation and targets replacements for NetSuite, Sage Intacct, SAP, and QuickBooks.

Product overview

Rillet is offered as a single unified AI-Native ERP platform (a general-ledger-first accounting system) rather than a stitched-together suite, and is sold primarily to high-growth startups, mid-market companies, accounting firms, and finance teams that have outgrown legacy ERPs like NetSuite, Sage Intacct, SAP, QuickBooks, and Xero. The core perpetual general ledger powers a set of tightly-integrated modules — Automated General Ledger, Accounts Receivable, Accounts Payable, Bank Reconciliation, Close Management, Native Integrations, Flexible GAAP Reporting, Advanced Revenue Recognition, Multi-Entity & Accounting Consolidation, Security and Permissions, and SaaS Reporting — that together deliver the Zero-Day / Continuous Close promise. Layered on top of the GL, Aura AI (along with its Aura Flow workflow automation and Aura AI Agents) injects generative AI, natural-language Q&A, contract analysis, ASC 606 analysis, and predictive cash-flow insights across the platform. The system is complemented by a public Rillet Accounting API (with an MCP server for AI agents), the Vibe Academy finance-engineer enablement program, and a CPA-led implementation model.
