The Problem

Homeowners struggle to get comparable quotes from contractors. Existing platforms like Angi and Thumbtack sell leads to contractors who then overwhelm homeowners with calls. There's no structured way to compare bids apples-to-apples, verify contractor quality, or ensure fair pricing.

The Solution

A reverse-auction platform where homeowners describe their project (with AI-assisted scoping and photo upload), and vetted contractors submit structured bids with itemized pricing, timelines, and references. AI provides price benchmarking against local market rates so homeowners know if bids are fair.

Executive Summary

The construction bid management software market is $1.08B in 2025 growing at 12% CAGR. Angi, Thumbtack, and Houzz dominate home services but homeowners still report frustration with lead-gen models that prioritize contractor volume over quality. A bidding-first platform that lets homeowners post projects and receive structured, comparable bids could differentiate. However, the marketplace cold-start problem is brutal in local services, and incumbents have raised billions.
