Rillet hits $1B valuation with $100M Series C led by ICONIQ

The accounting platform is betting AI can end the manual monthly close that keeps finance teams working weekends.

• Rillet raised a $100 million Series C led by ICONIQ Capital, valuing the AI-native accounting startup at $1 billion and pushing it into unicorn status.
• Founded in 2021, Rillet builds an AI-native ERP that automates the general ledger, accounts receivable and payable, bank reconciliation, and revenue recognition for finance teams.
• The round is Rillet's third fundraise in the past year, pushing total funding past $200 million, and ICONIQ general partner Seth Pierrepont is joining the board.
• CEO Nicolas Kopp says the platform aims to spare CFOs from the manual data review and slideshow-building that often eats into their weekends.
• The deal reflects strong investor appetite for AI-native challengers aiming to replace decades-old enterprise finance software as accounting automation becomes a hot funding category.
