Rillet serves accounting and finance teams, the financial brains of their companies. Our job is to help them run the numbers with impossible speed, accuracy, and insight.
Rillet is the AI-native ERP built for modern finance teams. We help companies automate the most critical parts of finance, from closing the books and recognizing revenue to consolidating entities and reporting to investors. More than 600 companies run on Rillet, including Mercor, Scribe, and Function Health, and we partner with leading accounting firms including EY and KPMG.
This huge market is ours to take. We’ve raised $200M+ from Sequoia, a16z, ICONIQ, Bain Capital Ventures, Oak HC/FT, and other leading investors to build the financial infrastructure for the next generation of companies and help every business run its numbers at the speed of AI.
Who We AreRillet’s pace is not for everyone. Intelligence is table stakes. To succeed here, you need extreme speed, agency, and flexibility.
The people who thrive at Rillet do not wait for assignments. They internalize the mission, design a strategy, and bring back results that are better, faster, and more creative than a manager could have asked for.
Our work revolves around our customers. The people who succeed here are energized by delivering what matters most, even when it was not part of the original plan.
Rillet is built on deep accounting expertise, and it takes people from many disciplines to build a category-defining company. You do not need to be an accountant to thrive here. You do need to care deeply about the problems we solve and the impact our customers can create. Together, we combine the precision of accounting with the speed, creativity, and ambition of AI-native software to power the financial core of the world’s fastest-growing companies while redefining what finance teams should expect from their software.
