Some of the firm's clients are Minoa, lokalise, Dextego, Warmly, graph8 and BEAM. The company was co-founded by Nicolas Kopp (CEO as of 2026) and Stelios Modes. In August 2026, Rillet raised USD 100 million in series C funding led by ICONIQ Capital, with participation from Andreessen Horowitz, Creandum, Oak HC/FT, and Sequoia, Bain Capital Ventures, Battery Ventures, FirstMark Capital, Scale Venture Partners, Sequoia Global Equities. 

Rillet offers an ERP solution designed for SaaS and usage-based businesses, automating financial workflows such as invoicing, revenue recognition, and multi-entity consolidation. By integrating with platforms like Stripe and CRM systems, Rillet enables real-time financial reporting, customizable SaaS and GAAP metrics, and AI-powered analytics. The platform streamlines the contract-to-cash cycle, helping businesses close their books faster, improve accuracy, and enhance operational efficiency.

Rillet generates revenue by offering subscription-based pricing for its cloud-based platform, with different plans such as Starter Scale and Enterprise plans, designed to cater to the needs of various businesses.

The company plans to use the August 2026 funding to build and expand its agentic finance operating layer, where finance professionals and artificial intelligence agents work from the same general-ledger data, accounting policies and controls.
