Rillet

Rillet builds an AI-native ERP and general-ledger platform for finance teams, automating journal entries, reconciliations, and month-end close as a replacement for legacy systems, with native integrations to tools such as Salesforce, Stripe, Brex, and Ramp. Founded in 2021 by CEO Nicolas Kopp (former US CEO of the digital bank N26) and Stelios Modes, the company is headquartered in New York with offices in San Francisco and Barcelona. Customers include Windsurf, Bitwarden, and Decagon. Rillet raised a $70M Series B in August 2025 co-led by Andreessen Horowitz and ICONIQ, with Sequoia and Oak HC/FT, bringing total funding to more than $100M in under a year.
