Rillet Raises $25M to Cut Financial Close Time from Weeks to Hours

Rillet, an AI-native enterprise resource planning (ERP) platform, announced that it has raised $25 million in Series A funding led by Sequoia Capital. The round comes just 10 months after the company's previous fundraise and includes participation from existing investors First Round Capital, Creandum, and Susa Ventures, along with notable angel investors including former NetSuite CFO Ron Gill and former Twilio CFO Lee Kirkpatrick.

The San Francisco-based startup is tackling one of enterprise software's most entrenched problems: outdated financial systems that prevent companies from fully leveraging artificial intelligence. Many accounting teams today still rely on legacy ERP systems and tools dating back to the 1990s, including products like NetSuite that have become slow, manual, and bloated through years of customization.

Rebuilding Financial Infrastructure

Rather than attempting to modernize existing systems, Rillet has taken the ambitious approach of rebuilding the general ledger entirely. The platform integrates directly with modern business tools including Salesforce, Stripe, Ramp, Brex, and Rippling, while deploying AI agents to automate critical accounting workflows spanning accruals, reconciliation, and board reporting.

"We're a team of accountants building for accountants. This means everything from the reports to the workflows is tailor-built for the challenges CFOs and controllers deal with on a daily basis," said Nicolas Kopp, CEO and co-founder of Rillet.
