What RealEstateAPI does
RealEstateAPI is a U.S.-based property data API platform covering 159M+ U.S. properties, founded in 2016 by Vince Harris (CEO, former Director at a private placement fund that deployed $1B+ in capital) and Justin Winthers (CTO, formerly engineering lead at Marriott and NRECA and principal at a mortgage broker). The platform unifies assessor data, recorder data, MLS listings, and property imagery into a single REST API, replacing the 3-5 separate data file calls typically required by legacy providers. Core products include Property Search (100+ filter parameters), Property Detail, AutoComplete (free, unlimited), Property Comps, Property Mapper, AVM with confidence scoring, real-time MLS search, Skip Trace (237M+ people with Tier-1 demographics), Involuntary Liens, Bulk Endpoints, and a 2025-launched set of MCP servers exposing the full API natively to Claude, ChatGPT, Cursor, Windsurf, VS Code, and Claude Desktop.
The company operates a hybrid product-led and sales-led GTM: self-serve Developer Console with instant API key provisioning and a free trial, plus sales-assisted motion for Growth, Pro, and Enterprise tiers. Pricing is credit-based — Starter $599/month (30K credits), Growth $1,200/month (150K credits), Pro $2,500/month (400K credits), Enterprise custom, and Pay-As-You-Go $0.10/record — roughly half the cost of legacy bulk data providers. Premium add-ons (Lender-Grade AVM from $250/month, Involuntary Liens $0.50-$1/lookup, Skip Trace $0.05/match) generate incremental revenue. Customer base of 300+ enterprises spans PropTech, fintech/mortgage lending, real estate investing, solar/home services, and e-commerce, with named customers including Sunrun, Carrot, We Buy Houses, Housefolios, Investor Base, and Peakzi. Marketing centers on the Ground Truth podcast, G2 #1 ranking for Ease of Admin in Property Intelligence, and developer community channels.
The company was bootstrapped without institutional venture capital, scaled to multi-million-dollar ARR while remaining profitable, doubled its customer count in 2025, served 2B+ API calls cumulatively, and was acquired by Beacon Software Inc. (Toronto-based AI infrastructure company backed by General Catalyst and founders of Stripe, DoorDash, and Ramp) in an eight-figure transaction in early 2026. RealEstateAPI now operates as the core property intelligence layer within Beacon's AI software ecosystem targeting Main Street businesses. The 12-person team is concentrated in engineering, with active hiring for additional engineers as of the latest reporting.

RealEstateAPI competitors and assessment
Company assessmentDirect peers
- ATTOM Data Solutions: ATTOM is the closest direct competitor to RealEstateAPI — a property data API platform covering 155M+ US properties with assessor, recorder, MLS, AVM, and skip trace products sold via subscription tiers to PropTech, real estate investors, and lenders. Both compete head-to-head on price-per-record and unified property payloads.
- HouseCanary: HouseCanary offers residential property data and analytics APIs including AVMs, comps, and rental valuations targeting mortgage lenders and investors. Overlaps with RealEstateAPI on AVM add-on and property detail endpoints serving similar fintech/lending buyers.
- PropStream: PropStream is a leading software platform for real estate investors combining property data, comps, skip tracing, and lead lists. Competes with RealEstateAPI in the investor / PropTech segment with bundled workflow tools rather than a pure API, but draws from overlapping data sources and customer base.
- BatchLeads: BatchLeads provides skip tracing and list-building tools for real estate investors and acquisition teams. Direct overlap on Skip Trace functionality and investor-targeted workflows, though delivered as a SaaS application rather than a developer API.
Broad incumbents
- Black Knight (ICE): Black Knight, also now part of ICE, is a major mortgage and real estate technology incumbent offering property data, servicing, and origination platforms. Competes for the same fintech/mortgage lender buyers RealEstateAPI serves via bundled enterprise offerings.
- CoreLogic (ICE Mortgage Technology): CoreLogic, now part of Intercontinental Exchange, is the dominant legacy property data and mortgage technology vendor. RealEstateAPI explicitly positions against CoreLogic's "expensive, complex bulk licenses" and is winning switching deals like Carrot — making CoreLogic the primary incumbent being displaced.
- Zillow Group (Bridge API): Zillow Group operates one of the largest US property databases and offers data licensing through its Bridge API to MLSs and enterprises. Overlaps with RealEstateAPI on MLS listing data and address-level property intelligence but at very different scale and business model.
Emerging players
- Mashvisor: Mashvisor provides real estate investment analytics including property data, comps, and rental yield analysis. Overlaps with RealEstateAPI on investor-targeted analytics use cases but is more verticalized toward Airbnb/long-term rental analysis rather than general API access.
- Reonomy (Altus Group): Reonomy (acquired by Altus Group) provides commercial property intelligence and owner data via API and SaaS, overlapping with RealEstateAPI's corporate/owner data capabilities though focused on commercial rather than residential.
- RentCast: RentCast offers a property data API focused on rental market data — AVMs, rent estimates, and market analytics — with developer-friendly pricing. Smaller scale than RealEstateAPI but increasingly competes for PropTech developer budgets on API-based property intelligence.
