What Restb.ai does

Restb.ai (legal entity Mercurio Platform, S.L.) is a Barcelona-headquartered computer vision AI company founded in 2015 that builds image-recognition technology purpose-built for real estate. Its core product is a cloud-based RESTful image recognition API that analyzes property photos — individually and holistically — to classify rooms, identify interior/exterior features and architectural styles, score property condition and quality against UAD C1-C6/Q1-Q6 standards, flag compliance violations (watermarks, signs, duplicates), generate alt-text captions for SEO and ADA, and auto-write listing descriptions. Outputs are returned in standardized formats (RESO, PDR, PDC, and 1004/Form 70/1073/30), enabling direct integration into downstream real-estate software.

The company operates an API-first B2B model with hybrid subscription + usage-based pricing — a fixed monthly fee includes a set number of API calls with overage charges for additional usage, and batch pricing is available for datasets exceeding 1 million properties. Distribution runs through direct enterprise sales, channel partnerships with MLS software providers (Rapattoni, NAVICA, ICE/Black Knight), and integration partnerships with appraisal/valuation technology platforms (ACI/First American, Bradford Technologies, Stewart Valuation Intelligence, AssetVal, True Footage, Aivre) and capital-markets tools (Aperture, Restb Lens). Restb.ai serves five primary use-case segments — AVMs/iBuyers/investors, appraisals and inspections, MLSs, property search and marketing, and insurance — across more than 100 enterprise clients including 20+ publicly traded companies and unicorns, reaching 1M+ real estate agents via 100 MLSs in the U.S. and Canada as of April 2026.

The business model is anchored in long-cycle enterprise contracts with high renewal stickiness given deep workflow integration. On May 12, 2026, Restb.ai was acquired by Clear Capital (a Nevada-based real estate analytics and valuation technology company backed by GTCR) and continues to operate as a retained brand alongside CubiCasa within Clear Capital's portfolio. Pre-acquisition the company had raised approximately $3.3M in disclosed funding across a 2017 seed round and a 2018 Horizon 2020 grant, suggesting historically lean capital usage relative to the scale of its enterprise footprint.
