Rillet Raises $70M to Redesign Enterprise Accounting with AI-Native ERP Built for Modern Finance Teams

Rillet, the AI-native ERP (Enterprise Resource Planning) platform designed specifically for finance teams, today announced a $70 million Series B round co‑led by Andreessen Horowitz and ICONIQ Capital, bringing its total funding to over $100 million in under a year. New board members Alex Rampell (Andreessen) and Seth Pierrepont (ICONIQ) join the board as Rillet accelerates its mission to disrupt century-old accounting systems.

This raise comes just ten weeks after a $25M Series A led by Sequoia — a reflection of skyrocketing traction. Since launch in 2024, Rillet has signed over 200 customers and doubled its annual recurring revenue in the past 12 weeks. Strategic partnerships with top U.S. accounting firms like Armanino and Wiss further validate its market credibility.

From Pain Points to Smart Ledger Architecture

Traditional ERPs are essentially “dumb databases”: they accumulate transaction data, but leave analytics and reconciliation to spreadsheets and external tools. Rillet reinvents this model by embedding machine learning and AI at the core. Native integrations ingest structured data—invoices, payments, CRM, banking—into a smart general ledger that automates workflows, journal entries, reconciliations, revenue recognition, and investor reporting, all within one unified system.

By bringing automation into the system’s fabric rather than layering it on, Rillet achieves real‑time processing: finance teams collaborate live, close books in days instead of weeks, and obtain instant insights as events occur—not in retrospect. Customers like PostScript close their books in just three days, and Windsurf runs its finance ops with a two-person team—demonstrating scale, speed, and lean operations.

Rillet was built with deep industry expertise at its core. It was co‑founded by Nicolas Kopp, former U.S. CEO of N26, and Stelios Modes, the technical architect behind N26's payment infrastructure, bringing together finance and engineering at the outset. The broader team combines experienced software engineers with seasoned finance and accounting professionals. This accounting-driven foundation ensures every workflow, feature, and implementation reflects the real-world discipline, rigor, and compliance that modern finance teams demand.

Why Timing—and Vision—Matter

The global accounting software market exceeds $500 billion, but remains dominated by slow-moving incumbents—Oracle’s NetSuite, Sage Intacct, Microsoft Dynamics, and private equity-rolled platforms like Acumatica. Meanwhile, finance is facing a talent crisis: an estimated 75% of accountants are expected to retire in the next 15 years, and up to 80% of routine financial tasks could be automated. Rillet arrives at this inflection point with a solution built to scale smartly with lean teams.

“As finance talent thins, every company needs smarter systems,” says Seth Pierrepont of ICONIQ. “Their AI-native approach gives companies faster insights, leaner teams, and smarter decisions—foundational infrastructure for next-generation growth.” Alex Rampell adds: “Finance teams deserve the same AI advantages that revolutionized sales, engineering, and legal.”

The Future of Finance: AI-Native Accounting as the New Infrastructure Layer

The enterprise finance function is undergoing a fundamental transformation. As businesses scale faster and operate leaner, the need for real-time, intelligent financial systems has become mission-critical. Traditional ERP software, built for a slower, manual world, is giving way to a new class of platforms—AI-native, collaborative, and deeply integrated into the broader fintech ecosystem.

This shift is about more than automation. AI-native ERP enables adaptive close processes, multi-entity consolidation, dynamic revenue recognition, and continuous reporting—capabilities that align with how modern companies operate across borders, time zones, and systems. By embedding machine learning into the system’s core, finance teams are freed from transactional bottlenecks and empowered to focus on strategic, data-driven decisions.

The long-term trajectory points to finance infrastructure that functions not as a backend tool but as a real-time operating layer—where human expertise is amplified by AI agents, and insights surface instantly. With several high-growth companies preparing to go public using this model, it’s increasingly clear: the future of enterprise accounting is intelligent, automated, and built to scale—and Rillet is helping lead the way.
