Rillet Raises $100 Million Series C at $1 Billion Valuation, Becomes AI Accounting Unicorn

Rillet, an AI-native accounting and ERP startup, has raised a $100 million Series C at a $1 billion valuation, making it a unicorn about two years after emerging from stealth. The round was led by ICONIQ, with returning investors including Sequoia and Andreessen Horowitz, and it brings the company’s total funding to more than $200 million. The funding highlights continued investor appetite for AI software that automates finance work, and it gives Rillet more capital to expand its accounting platform for modern finance teams.
