Rillet Raises $70M to Rethink Finance Software from the Ground Up

Rillet has raised $70 million in Series B funding to replace legacy ERP systems with an AI-native platform built for modern finance teams. The round, co-led by Andreessen Horowitz and ICONIQ, brings its total funding to over $100 million in under a year. The company’s goal is simple: make accounting software faster, smarter, and actually usable by the people who rely on it every day.

In just a few months, Rillet has signed 200+ customers, doubled ARR, and partnered with top accounting firms. Fast-growing companies are using it to close books in days, not weeks, and run lean teams without sacrificing control. Unlike traditional ERPs that bolt AI on the side, Rillet bakes it in - automating workflows, syncing data from the start, and delivering real-time insights without the spreadsheet sprawl.

The platform’s architecture is its edge. Old systems store transactions and push the real work into Excel. Rillet flips that: structured data flows in, AI handles the grunt work, and teams focus on strategy. It’s built by accountants, not just engineers, and that shows up in how fast it’s implemented and how well it fits into daily workflows.

With finance talent shrinking and automation rising, Rillet is hitting a nerve. It’s not just updating old tools, it’s redefining what finance teams can do with fewer people and better systems.
