AI-Native Accounting Startup Rillet Raises $100M Series C at $1B Valuation Led by ICONIQ

Rillet, an AI-native accounting platform aimed at automating CFO workflows, closed a $100M Series C led by ICONIQ that values the company at $1B and takes total funding past $200M. CEO Nicolas Kopp framed the pitch to Fortune as augmenting rather than replacing finance teams; the round follows a wave of AI-in-finance rounds hitting unicorn status this cycle.
