Nicolas Kopp was not trying to raise money. His accounting startup, Rillet, had closed a $70m round last year and was busy signing up finance teams who were sick of fighting their own software. Then the term sheets started landing, and by his own account on X the whole thing came together in “less than 48 hours.”
The upshot, confirmed on Tuesday 19 August, is a $100m Series C at a $1bn valuation, led by Iconiq, with Andreessen Horowitz and Sequoia both writing follow-on cheques. Rillet only came out of stealth in 2024. Two years later it is a unicorn, and the legacy accounting giants have a real reason to look over their shoulder. (Not investment advice.)
An accountant that never sleeps
Rillet sells an AI-native general ledger. Rather than treat the ledger as a dusty system of record, it wires AI agents into the core and lets them handle the grinding month-end work: pulling data continuously from tools like Salesforce and Brex, reconciling accounts, and closing the books in a fraction of the usual time.
The company calls the goal “accounting superintelligence,” which is the sort of phrase that makes a sensible controller wince. Strip the marketing off, though, and the pitch is concrete. Rillet claims more than 600 customers, including publicly listed companies, and says it doubled its annual recurring revenue in the past three months. In April it signed an alliance with EY, the kind of blue-chip stamp that gets finance chiefs to return your calls.
Why the money moved so fast
This is Rillet’s third raise in roughly 14 months. It took $25m from Sequoia in a Series A in May 2025, then $70m in a Series B led by Iconiq and Andreessen Horowitz, and now $100m more. Total funding sits north of $200m, and the valuation has gone from nothing to ten figures at a pace that would have looked reckless a couple of years ago.
The target is obvious: Oracle’s NetSuite and the other legacy enterprise resource planning systems that finance teams love to hate. Investors are betting that AI lets a young company rebuild the ledger from scratch and peel off customers who never wanted their existing software in the first place. Talk of a “SaaSpocalypse,” where AI-native tools gut incumbent vendors, may be overcooked, but there is genuine smoke here.
The bit worth questioning
A $1bn valuation on a two-year-old company is a statement of faith, not a verdict. Rillet has not published an absolute revenue figure, only that it doubled, so “doubled from what” remains the polite question. Handing autonomous agents the keys to a company’s books also raises real worries about errors, auditability and who carries the can when a machine miscodes a transaction. Accounting is one of the few trades where “roughly right” is a sackable offence.
None of that changes the direction of travel. Iconiq’s Seth Pierrepont said the firm backed “a bold vision” a year ago and that the vision is “now reality.” Reality in venture terms means a fresh $100m and a mandate to grab share before the incumbents wake up. If Rillet keeps doubling, the next round will make this one look cheap. If the growth stalls, a $1bn tag on modest revenue will look very different. (Not investment advice.)
Did you know: Oracle bought NetSuite, the cloud ERP pioneer Rillet is now chasing, for about $9.3bn back in 2016. Rillet is trying to unseat it with less than a fortieth of that in total funding.
