CooperBuild

AI-native operating system for general contractors: estimates, takeoff, bids, pay apps. CooperBuild is built around one idea: the estimate is the company. Approving a proposal clones the estimate into the live project, and takeoff, vendor quotes, pay apps, payroll and the general ledger hang off the same deliverables. Agents can sign up on their own via OAuth dynamic client registration and an email-code bootstrap.
