XBuild, a construction-tech startup that provides an AI-native estimating and proposal platform for contractors and insurers, with an initial focus on residential roofing and insurance restoration work, has raised $19 mn in Series A funding to expand its AI-native estimating platform serving contractors and insurers.
The round was led by N47, with participation from Rackhouse Ventures and Andreessen Horowitz.
Launched in 2025, XBuild entered the market with an insurance-focused estimating product designed to generate carrier-aligned repair estimates.
Since launch, the platform has processed more than 15,000 completed projects representing roughly $250 mn in construction volume.
Adoption has been strongest in property insurance claims, particularly residential roofing, where XBuild says customers avoided more than 40,000 hours of manual estimating work.
According to Beinsure, estimating accuracy and speed remain persistent friction points in claims workflows, especially in trades where pricing volatility and documentation standards continue to rise. XBuild’s early traction reflects that pressure.
Building on that usage, XBuild introduced Roofing Proposals, a product aimed at residential contractors that generates detailed, editable estimates in under 15 minutes.
The platform ingests PDF measurement reports from EagleView, Hover, Roofr, and similar providers, alongside standard job-site photography, translating that input into structured proposals ready for client delivery.
The system connects directly with ABC Supply to pull real-time material pricing and includes homeowner-facing tools such as digital proposals, tiered Good Better Best pricing, e-signatures, and embedded payments via Stripe. The objective stays practical. Reduce turnaround time without forcing contractors into rigid templates.
Matthew Cowan, general partner at N47, said estimating and proposal generation remain core operational bottlenecks across construction.

He said legacy software failed to adapt to modern workflows or AI capabilities, while XBuild applies automation where it produces measurable efficiency gains rather than abstract optimisation.
XBuild was founded by Jahan Khanna and Rob Moran, both former executives at Uber and Postmates, alongside civil engineer Sharuk Khanna.
The founding team blends marketplace scale experience with trade-specific engineering, a mix investors continue to favour in construction technology.
XBuild leverages deep industry expertise to deliver compelling automation and efficiency gains in construction, representing a cutting-edge application of AI to real-world problems.

The company plans to expand into additional verticals including HVAC, concrete, and window installation. At the same time, it continues to support insurers and insurance-focused contractors through its Insurance Estimation Copilot, which remains in active production use across claims environments.
Jahan Khanna said construction costs remain one of the few areas where technology adoption lags materially behind other sectors.
He framed faster, cheaper building as part of a broader response to cost-of-living pressure, with AI-driven estimating positioned as a lever rather than a silver bullet.
XBuild positions itself at the intersection of contractor productivity and insurer requirements, offering standardised, carrier-ready estimates designed to reduce dispute cycles and improve clarity across claims workflows.
According to Beinsure, tools that sit between contractors and insurers, rather than forcing either side to adapt, are gaining traction as claims volumes rise and skilled labour remains constrained.
