Rivvun AI builds an autonomous, agentic execution layer that sits on top of enterprise ERP, CRM and procurement systems such as SAP, Ariba and Salesforce. Its agents continuously sense commercial events, detect discrepancies between contracted terms and actual invoicing or spend, and write policy-backed corrective actions back into the source systems. The company targets enterprise revenue and margin leakage — money that is contractually owed but never collected or overpaid. It was founded by former Icertis executives and raised a $7.55M seed round from Sitara Capital and 3one4 Capital in 2026.
