Founder of GUILD, Making aerospace parts faster and cheaper for defense

Company

Kaya Celebi is listed as a founder of GUILD. GUILD is making aerospace parts faster and cheaper than today’s defense supply chain. We win defense contracts, automate manufacturing, and deliver to the government's door. We’ve built an AI-native operating model for defense contracting: a company brain that connects requirements, pricing, supplier capability, compliance, manufacturing, finance, and delivery so each contract makes the next one faster and cheaper.
