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.

Why XBuild is interesting

$250M+ in projects estimated in year one — Uber/Postmates alumni applying AI to roofing and restoration workflows insurers also use.

Product & use cases

XBuild uses AI to generate accurate construction estimates from photos, plans, and job parameters — outputting insurer-ready proposals and contractor bids faster than manual takeoff processes.

  • Roofing contractors producing insurance restoration estimates from drone or mobile photos
  • Restoration companies accelerating storm-response bid volume
  • Insurers and adjusters validating contractor estimates via XBuild workflows

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.

  • Hover direct

    Property measurements and estimates from photos; overlapping roofing/restoration use cases.

  • ProEst / Sage estimating incumbent

    Traditional construction estimating software; less AI-native.

  • Xactimate (Verisk) incumbent

    Insurance industry standard for claims estimating; XBuild targets contractor-side acceleration.

Notable stories

  • XBuild founders applied marketplace logistics experience from Uber and Postmates to construction — where estimating bottlenecks cost contractors storm-season revenue (PR Newswire, 2026).
