XBuild, a construction-tech startup with an AI-native estimating and proposal platform for contractors and insurers, has raised $19m in Series A funding.
The new funding will allow XBuild to expand into additional verticals, including HVAC, concrete, and window installation, while continuing to support insurers and insurance-focused contractors through its Insurance Estimation Copilot, which remains in active use across claims environments.
Matthew Cowan, general partner at N47, said, “Estimating and proposal generation remain major bottlenecks for contractors, yet legacy tools haven’t kept pace with AI capabilities or the realities of how the industry works today.” He added that legacy software has failed to adapt to modern workflows, whereas XBuild applies automation, which delivers measurable efficiency gains rather than abstract optimisation.
