Rillet is building the next-generation, AI-native enterprise resource planning (ERP) platform designed specifically for finance teams at fast-growing and complex businesses. Its core product is a modern, intelligent accounting system that replaces legacy ERPs and outdated accounting software by automating workflows, streamlining close processes, and delivering real-time financial insights. Rillet serves companies with multi-entity structures, complex revenue models, and high transaction volumes—helping them close their books in hours instead of days, automate reconciliations, and generate investor-ready reporting with minimal manual intervention.
The company has experienced rapid growth since emerging from stealth in 2024, serving over 200 customers—including high-growth startups and mid-market enterprises—and doubling its annual recurring revenue (ARR) quarter-over-quarter. Backed by leading investors like Andreessen Horowitz and ICONIQ Growth, Rillet is positioned at the forefront of a major shift in enterprise finance, where automation, AI, and real-time data are redefining what finance teams can achieve.

Rillet was founded in 2021 by Nicolas Kopp, former US CEO of N26 and ex-Morgan Stanley executive, and Stelios Modes, a technology leader with experience at ThoughtWorks and Shazam. Both founders were deeply familiar with the pain points of legacy accounting systems, having navigated complex migrations and manual processes at scale. Their frustration with the inefficiencies of traditional ERPs—lengthy implementations, brittle workflows, and the reliance on spreadsheets—led them to build a new kind of financial infrastructure from the ground up.
The idea crystallized around the belief that finance teams should not be bogged down by manual data entry and reconciliation. Instead, they should be empowered by a system that automates routine tasks and surfaces actionable insights in real time. Early traction came from companies outgrowing QuickBooks and Xero, as well as larger organizations seeking to replace entrenched ERPs like NetSuite and Sage. Rillet’s ability to onboard customers in weeks—not months—became a key differentiator, fueling rapid adoption and word-of-mouth growth.

Rillet is riding the convergence of three powerful trends: the AI revolution, the talent crunch in accounting, and the demand for real-time financial decision-making. The accounting industry faces a looming retirement wave—75% of accountants are expected to retire in the next 15 years—while 80% of routine financial work is ripe for automation. At the same time, businesses are increasingly data-driven, requiring faster, more accurate financial insights to stay competitive.
By reimagining ERP as a “system of action” rather than a static “system of record,” Rillet is helping to modernize the financial backbone of enterprises. Its platform is not just automating tasks but enabling a new way of working where AI agents and human expertise collaborate to drive strategic outcomes. This shift is influencing the broader ecosystem by setting a new standard for what finance software can—and should—deliver.

Rillet is poised to become the foundational infrastructure for the next generation of finance teams. As AI continues to evolve, the company is moving beyond automation toward agentic workflows, where AI agents proactively manage accruals, audit prep, and financial analysis. The future will likely see deeper integrations with business intelligence tools, expanded use cases for predictive analytics, and broader adoption across industries.
The timing is critical: as legacy ERPs struggle to keep pace with modern business needs, Rillet’s AI-native approach offers a compelling alternative. Its influence will extend beyond accounting, shaping how companies think about financial operations, data governance, and strategic decision-making. Just as cloud computing and SaaS transformed enterprise software, Rillet is leading the charge to make finance systems as agile, intelligent, and user-friendly as the rest of the modern tech stack.
