The AI estimator that wants a contractor to inspect, quote, and close a job before leaving the driveway.
The NameplateA four-character web address, x.build, doing the work a whole brochure used to do. The logo travels light - which is roughly the pitch.
Here is a fact about the construction industry that is either boring or extraordinary depending on how you look at it: a large share of the money in the physical world - the roofs, the gutters, the drywall, the insurance claims that pay for all of it after a storm - gets estimated by hand. Someone climbs a ladder, takes some measurements, opens a spreadsheet or a piece of legacy software, and produces a number. The number matters enormously. It is the difference between a job won and a job lost, between a claim paid and a claim short. And it takes a while.
XBuild is a San Francisco company that looked at that process and concluded, reasonably, that an AI could do the tedious part. Founded in 2023 by Jahan Khanna and Rob Moran - who previously ran operations at Uber and Postmates - together with civil engineer Sharuk Khanna, the company builds what it calls an AI-native, agentic estimating platform. You give it site photos and a measurement report. It gives you a standardized, editable, code-compliant estimate in minutes.
The interesting thing about that description is what it does not require: no demos, no onboarding, no consultants configuring line items for six weeks. The AI was trained on the inputs contractors already produce, which is a polite way of saying XBuild tried to meet its customers where they already stood rather than asking them to move.
This is the sort of unglamorous, enormous market that venture capitalists have learned to like. In January 2026, XBuild raised a $19 million Series A led by N47, with participation from Rackhouse Ventures and Andreessen Horowitz. The money is meant to take a workflow that works in roofing and repeat it across the rest of the trades.
Construction and the cost of building remain largely untransformed by technology. XBuild will catalyze change through AI innovation.
The pitch is a loop. A contractor walks a property, snaps photos, and the AI writes descriptions, checks building codes, folds in weather data for insurance claims, and produces a proposal a homeowner can sign - with a Stripe deposit collected on the spot.
Generates insurance-ready estimates and supplements from measurement reports and labeled photos, with code checks and weather-data integration for restoration claims.
Produces a finished, branded residential roofing estimate in under 15 minutes, wired to real-time supplier pricing from ABC Supply with Good / Better / Best options.
A conversational, agentic estimator - the “vibe coding” of construction - that turns a job description, photos, and measurements into an editable line-item estimate.
Jahan Khanna, Rob Moran and Sharuk Khanna set out to point AI at construction estimating.
An insurance-focused point solution for restoration contractors goes live and finds early traction.
Raises $19M led by N47 with a16z and Rackhouse, and ships a residential roofing estimate built in under 15 minutes.
Estimating remains a major bottleneck; XBuild delivers compelling AI-driven efficiency gains.
It's an AI-native platform that turns site photos and measurement reports into standardized, code-compliant construction estimates - starting with roofing and insurance restoration.
