Brief

Rillet, as described by a16z (2026-06-09) and founder Nicolas Kopp, builds an AI-native ERP that makes traditional month-end closes obsolete by maintaining a "continuously closed" ledger that’s always accurate, complete, and reviewable. Automation posts most journal entries without human input, dramatically reducing month-end work while leaving humans to handle small reclasses and accrual corrections.

Source evidence

Rillet is making ERP AI-native:

  • A ledger that's always accurate, complete, and reviewable is "continuously closed."
  • That means no more month-end scramble. There's almost no manual work left at the end of the month.
  • The manual journal entry is nearly extinct. Entries are increasingly posted without a single human keystroke.
  • No business of a meaningful size will ever operate at 0% adjustments. Humans are still in the loop for small reclasses and accrual corrections.

We built Rillet on the idea that the centuries-old practice of "closing your books" should be obsolete.

Month-end, which used to be a scramble to reconcile everything and get the numbers to zero out, is now just another day.

Based on a sample of Rillet customers, we went deep with @a16z on how AI-native ERP is breaking the mold of traditional accounting.
