Zalos builds computer agents that automate repetitive finance operations tasks such as reconciliation, categorization, billing, accounts payable and form-filling. The agents integrate with existing systems like ERPs and accounting software (including NetSuite, Sage and SAP S/4HANA) by logging in directly with credentials and executing rule-based processes without heavy integrations. The company converts screen recordings of finance workflows into agents that operate inside ERPs, Excel, email and internal tools. Zalos is based in London and San Francisco and is part of Y Combinator's Fall 2025 batch.
