BuildZoom

What BuildZoom does

BuildZoom, founded in 2013 and headquartered in San Francisco, operates a data-driven construction marketplace that connects property owners with vetted contractors for residential and small commercial projects. The platform's foundation is a proprietary database aggregating 175+ million building permits, 3.5–4+ million contractor profiles, 7.5 million contractor licenses, and 135,000+ property owner reviews, enriched with state licensing board and Better Business Bureau data. At the core of the product is the BuildZoom Score, a composite metric that ranks contractors on license status, insurance, work history, consumer reviews, and consumer interest group standing. The platform facilitates 8,000+ projects per month with average project sizes exceeding $120,000 and serves 1M+ monthly users.

BuildZoom monetizes primarily through a success-fee model of 2.5–5% of project value, charged only when a contractor wins a job, aligning incentives across homeowners, contractors, and the platform. Additional revenue streams include a premium advisory service providing dedicated construction consultants for complex residential and commercial projects, and a data monetization business selling permit intelligence to construction suppliers, insurance carriers, real estate firms, and marketers. The go-to-market is hybrid: a free, self-serve marketplace for property owners and contractors paired with a sales-led enterprise motion for franchise brands managing multi-location buildouts. Customers include Cold Stone Creamery, Nekter Juice Bar, Prime IV Hydration, and individual homeowners and contractors documented in case studies showing $45K–$200K in savings.

In November 2025, BuildZoom Marketplace was acquired by Block Renovation to form what the acquirer describes as the nation's largest AI-driven renovation and construction platform, targeting the $700+ billion residential and small commercial construction market. BuildZoom is venture-backed with approximately $23.7 million raised across multiple rounds from 2013 to 2021, including a $10.6M Series A led by Formation 8 (2015) and a $9M round led by 8VC (2017), with prior participation from Founders Fund, Cota Capital, and Y Combinator. The company has 101–250 employees.

Direct peers

• Block Renovation: AI-driven renovation platform and BuildZoom's parent company following the November 2025 acquisition. Operates an overlapping marketplace connecting homeowners with contractors for renovation projects, with similar success-fee economics and contractor matching workflows.
• Angi: Public home services marketplace (formerly Angie's List, merged with HomeAdvisor) connecting homeowners with local service professionals. Directly comparable in lead generation, contractor matching, and consumer marketplace model, but at significantly larger scale with broader service categories beyond construction.
• Houzz Pro: Home renovation platform offering contractor directory, lead generation, project management software, and marketplace services. Competes directly with BuildZoom's contractor matching and premium advisory services, with a deeper design content and e-commerce moat.
• Thumbtack: Online marketplace connecting consumers with local professionals across more than 1,000 categories including home remodeling. Directly comparable marketplace and lead generation model, with broader service breadth but less construction-specialized data infrastructure than BuildZoom.
• Porch: Home services platform connecting homeowners with contractors and home improvement professionals, with built-in permit data and moving services. Comparable in contractor matching and home improvement marketplace focus, with overlapping permit intelligence capabilities.
• Sweeten: Renovation-focused marketplace offering free matching between homeowners and vetted general contractors with a hands-on concierge service model. Closely aligned with BuildZoom Premium's consultant-driven approach, though smaller scale and more concentrated geographically.

Broad incumbents

• Procore: Public construction management platform serving general contractors, owners, and specialty contractors with project management, financial, and quality/safety tools. Broader incumbent in construction software; complementary rather than directly competitive with BuildZoom's pre-construction homeowner-facing marketplace.
• ServiceTitan: Public software platform for home and commercial service businesses including plumbing, HVAC, electrical, and construction. Comparable in serving contractors with CRM and lead management tools, with broader trade coverage but less pre-construction marketplace focus than BuildZoom.

Emerging players

• BuildBook: Construction project management software focused on custom home builders and remodelers, offering client portals, scheduling, and change order management. Comparable in serving residential contractors and remodeling professionals, though positioned as project management rather than lead generation.
• CoConstruct: Construction project management and client portal software for custom home builders and remodelers. Comparable in serving residential contractors and providing client-facing tools, though primarily a software platform rather than a marketplace.
