Rillet sets a new standard for AI-native financial ERPs
Rillet offers an AI-native financial ERP that enables zero-day closes and reduces reliance on consultants. It supports multi-entity setups and streamlines reporting for growing companies.

Partnering with Rillet: The Financial ERP for the AI Age
Over the last decade, fintech has transformed most parts of financial operations, yet the general ledger (GL) remains stuck with legacy ERP systems like NetSuite and Sage. These systems, built decades ago, struggle to meet the needs of growing businesses. Scaling companies often face a tough choice: move from basic tools to complex, specialist-heavy ERP setups that require extensive manual work to close each month.
Replacing the general ledger is risky and challenging, which explains why legacy ERPs have stayed dominant. But Rillet’s co-founders, Nicolas Kopp and Stelios Modes, took on this challenge head-on. They built an AI-native ERP from scratch, focused on helping CFOs achieve zero-day closes and eventually enable a “one-person Finance function.”
Why Rillet Stands Out
Rillet’s platform offers multi-entity support and advanced revenue recognition, making it ideal for companies outgrowing QuickBooks or struggling with outdated NetSuite systems. The founders’ experience scaling the neobank N26 gave them firsthand insight into the gap between legacy ERPs and modern user experiences.
The platform is designed to minimize reliance on consultants and reduce deployment times from months to weeks. Its user-friendly workflows and real-time reporting include pre-built metrics tailored for investors, streamlining what used to be a cumbersome process.
Early Success and Market Response
Rillet has quickly gained traction, attracting clients like Windsurf and Decagon. Customer feedback is overwhelmingly positive, with an NPS above 70 and perfect reviews on G2. The promise of zero-day closes is becoming a realistic goal rather than a rare achievement.
Looking Ahead
With a team spread across New York, Barcelona, and Menlo Park, Rillet is gearing up to introduce agentic automation features that will simplify auditing, accrual, and reconciliation. This next phase aims to further lighten the workload for finance teams, making CFOs’ lives easier and more efficient.
Thanks to the vision and execution by Nicolas, Stelios, and their team, finance leaders now have a modern foundation to build on for years to come.
