Walter on the record

What they shipped

  • From its YC profile: Walter is an AI employee for manufacturing operations. (source)
  • Its own site describes it as: "Walter - document work automation that handles your paperwork. Read documents, capture and validate data, route approvals, and write to your ERP." (source)
  • From the Launch YC post "Walter: AI Employee for the Manufacturing Back Office": Walter is an AI employee for the manufacturing back office. Instead of building yet another integration, we gave Walter a login. He signs into SAP, Microsoft Dynamics 365, or Oracle the way a new hire would, works out of Teams and email like the rest of the team, and takes over the manual work no one wanted: entering purchase orders, ordering from suppliers, catching pricing errors before they ship. (source)

Who is behind it

  • Nikolas Keller, Founder/CEO: First hire at GC-backed AI Manufacturing Startup, Prev. cooking in French, Italian and German Fine Dining Kitchens. CDTM, Z Fellows. (source)
  • Lukas Postulka, Founder/CTO: ex Quant Trader / TUM, Z Fellows. (source)

Timeline
