Walter

Walter is a San Francisco-based Y Combinator (Spring 2026) startup building an AI employee for the manufacturing back office. Founded in 2026 by Nikolas Keller (CEO) and Lukas Postulka (CTO), Walter logs into the enterprise systems a company already runs on — SAP, Oracle NetSuite, Microsoft Dynamics 365, Teams, Outlook and Gmail — the way a new hire would, and takes over manual paperwork: reading sales orders and purchase orders from emails and PDFs, capturing and validating the data, cross-checking it against the ERP, ordering from suppliers and catching pricing errors before they ship. It uses a purpose-built document-understanding model (rather than legacy template OCR) that supports 270+ languages and reaches 90%+ accuracy after minimal training, cutting an order that used to take 15 minutes down to about one. Walter requires no integration project and no rip-and-replace, operating the same screens the team already uses. It is an early-stage company with no public API, developer program, SDKs or documentation; this profile captures its public identity and security posture for the API Evangelist network.

Walter is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, AI Agent, Manufacturing, and ERP.
