## Summary

Raised $19M Series A (Jan 2026) led by N47 with a16z. Processed $250M in construction volume in year one. AI estimating for roofing, concrete, HVAC, plumbing, and glazing.

## Company Overview

XBuild is an AI construction estimating platform that automates the manual takeoff and bid preparation process for specialty trade contractors — one of the most time-intensive workflows in construction. The company raised $19 million in Series A financing in January 2026 led by N47 with Andreessen Horowitz participating, and processed $250 million in construction volume in its first year of operation.

Contractors using XBuild collectively saved 40,000+ hours on proposals in year one, compressing takeoff and estimate preparation from days to hours. The platform launched with roofing — a structurally complex calculation requiring slope, material quantities, and waste factors — and is expanding into concrete, HVAC, plumbing, and glazing through 2026, building toward a cross-trade estimating standard for the residential and light commercial construction segment.

The a16z backing and $250 million in year-one volume validate that AI estimating is ready for commercial deployment, not just demonstration. Construction estimating software is a large market with legacy players (PlanSwift, Bluebeam) that were not built for AI-native workflows. XBuild's multi-trade expansion roadmap positions it to capture the full specialty contractor workflow, not just a single trade vertical.
