Overview
XBuild provides AI-powered construction estimating and proposal software for contractors — especially roofing, restoration, and insurance-adjacent trades — automating takeoffs, pricing, and customer proposals. Founded by alumni of Uber and Postmates, XBuild reported estimating $250M+ in project value within its first year. The company raised a $19M Series A in January 2026 led by N47 with Andreessen Horowitz and Addition participating, following a16z seed participation in 2023.

Competitive landscape
Edge: Founders scaled logistics at Uber/Postmates — operational DNA for high-volume field workflows — applied to construction estimating bottleneck (speed + accuracy on insurance jobs).
Construction estimating is ripe for AI — manual takeoffs slow storm response and lose bids. XBuild competes with Hover on vision-based estimates and must integrate with Xactimate-heavy insurance workflows. $250M estimated year-one volume validates demand; Series A funds vertical expansion beyond roofing.
