Investing in Rillet

Seema Amble, Marc Andrusko, and Alex Rampell Posted August 6, 2025

If you ask finance leaders what they think about their accounting system, odds are you’ll get a groan before you get an answer. And it’s no wonder — most finance teams today are still stuck in the 1990s. Their software stack is brittle, clunky, and deeply manual. Ten-plus days to close the books. Sprawling teams of AR and AP “specialists.” Tedious workflows duct-taped together across Excel, Netsuite, and niche point solutions.

In an era of real-time decision-making and AI copilots, why does the financial nervous system of a company still run on software built for Windows 95?

Enter Rillet.

Rillet is building the AI-native enterprise resource planning (ERP) system — a self-driving finance system designed from the ground up for speed, intelligence, and automation. The platform combines a modern ledger and streamlined accounting workflows with specialized AI agents that actively manage financial operations, rather than passively recording them.

Unlike legacy ERPs and accounting systems that rely on static systems of record, siloed data, and limited, rigid integrations, Rillet is built as a system of action. It provides finance teams with real-time visibility and AI-powered tools to close books instantly, reconcile accounts automatically, generate board decks, run forecasts, create visual reports and dashboards, and more. For these reasons and countless others, Rillet serves as the source of truth for both GAAP financials and investor metrics.

And it’s working. From CFOs to staff accountants, Rillet gets rave reviews across the board. The feedback is consistent: this is finally the ERP that just works.

Why now?

We believe ERP is one of the most overdue categories in enterprise software for reinvention. It is also one of the largest. Rillet is going after a half-trillion-dollar market. This includes not only software licenses, but also the massive services layer that surrounds ERP implementation and maintenance. It also encompasses the manual labor required to enter data into ERP systems and extract insights from them.

The timing has never been better to reinvent this space. Three powerful forces are converging:

  1. AI is finally enterprise-grade: The emergence of highly capable foundation models means ERP agents are now capable of reasoning over contracts, workflows, and data with more precision than ever before.
  2. CFOs are under pressure to do more with less: Headcount reductions, efficiency mandates, and accounting labor shortages are driving demand — not just for visibility, but for deep automation across middle- and back-office tooling.
  3. New architectures enable new workflows: A unified data model, composable agents, and integrated automations allow Rillet to provide real-time finance, not just monthly snapshots.

We’ve long believed that the next generation of great enterprise companies won’t just “add AI” to existing software, they’ll be re-architected around it. Rillet is exactly that. We’re thrilled to lead Rillet’s Series B and partner with Nicolas Kopp and his exceptional team as they build the financial infrastructure for the AI-native enterprise.

If you’re a finance leader rethinking your finance stack — or an engineer excited by the idea of automating one of the world’s most antiquated software categories — come join us. This is just the beginning.
