XBuild

AI-native, chat-based estimating platform that turns measurement reports and jobsite photos into contractor-ready proposals

XBuild is an AI estimating platform for residential trade contractors — launched first for roofing — where users describe a project via an AI chat interface, or import measurement reports (EagleView, GAF QuickScope, Hover, Roofr) and jobsite photos, and the platform generates a standardized, editable estimate and a branded, shareable proposal (insurance-ready or retail Good/Better/Best options) with e-signature and Stripe-based deposit collection.

$19M Series A announced January 2026, led by N47 with participation from Rackhouse Ventures and Andreessen Horowitz (a16z) — consistent with seed_facts ("Series A $19M (a16z). Source: ENR") raisedEarly Stage
Founded 2022 per Crunchbase; however, vendor and press coverage describe 15,000+ projects run "in its first year" as of the January 2026 Series A announcement, suggesting the commercial product may have launched materially later than the 2022 company-founding date — flagged for human review · 15,000+ projects run to completion (~$250M in construction volume) in the platform's first year per the Series A announcement; contractors across roofing, siding, gutters, windows, and general contracting per vendor positioning; exact named-customer list not publicly disclosed

WHY IT EXISTS

Why This Tool Exists

The Problem

Residential trade contractors (starting with roofing) spend significant time manually building estimates and proposals from measurement reports and site photos using legacy template-driven tools, slowing down the sales cycle between a lead and a signed, priced proposal.

The Solution

Users describe the project via an AI chat interface, or the platform ingests measurement reports (EagleView, GAF QuickScope, Hover, Roofr) and jobsite photos; XBuild's AI analyzes the inputs, auto-writes photo-based inspection-report descriptions, and builds a standardized, editable estimate, producing insurance-ready or retail Good/Better/Best proposal options that homeowners can review and e-sign, with Stripe handling deposit collection — the vendor reports 15,000+ projects (~$250M in construction volume) run through the platform in its first year.
