Company profile

researched Aug 2026

Restb.ai develops computer vision and AI software that analyzes real estate photography and converts it into structured property data. Its models classify images by room type, identify interior and exterior features and architectural styles, score property condition and quality, detect watermarks, logos and duplicate or near-duplicate images, generate image captions and listing descriptions, surface visually similar properties and comparables, flag images that violate listing or report guidelines, and assess appraisal complexity. The company states its technology extracts more than 1,000 data points per property.

The products are sold to organizations across the real estate value chain: automated valuation model providers, iBuyers and investors; appraisal and inspection firms; multiple listing services; property search portals and marketing teams; and insurance companies. Use cases include improving valuation accuracy, automating listing population and MLS photo compliance, enhancing property search and SEO, and supporting appraisal review workflows. Coverage of the company notes its technology was integrated into multiple appraisal software platforms in 2024 and that it offers white-label solutions to mortgage lenders.

In May 2026 Clear Capital, a US real estate analytics, data solutions and valuation technology company, acquired Restb.ai for an undisclosed amount. Clear Capital said it would integrate Restb.ai's technology across its platforms and those of CubiCasa, the floor plan company it acquired in 2021, while retaining the Restb.ai brand.

Founding story

Restb.ai was launched in 2015 in Barcelona after co-founder Angel Esteban, while searching for a home for his wife and newborn son, encountered inconsistent listing quality and difficulty finding suitable properties. He teamed up with fellow AI specialist Xavi Hernando to build solutions aimed specifically at real estate, focusing on the untapped data contained in property photographs.

Business model

B2B software and data enrichment sold to real estate companies, which submit property imagery for automated analysis and receive structured visual insights and property data used in valuation, listing, compliance and marketing workflows. Solutions are delivered directly and, in the mortgage segment, as white-label offerings.

Traction

The company reports processing more than 2 billion property photos monthly and serving clients across five continents from offices in the US and Barcelona. Published customer outcomes include a real estate portal reporting a 46% increase in Google web traffic from SEO image captions, a Blackstone subsidiary saving over $1 million annually through automated property descriptions, an AVM reducing error rate by 9.2% using property condition models, a 50% reduction in manual review time, a 50% drop in revision requests, and a 28% increase in home sale prices when used within the Revive Real Estate Vision AI platform.

Latest developments

On May 12, 2026, Clear Capital announced the acquisition of Restb.ai for an undisclosed amount. Clear Capital and CubiCasa plan to integrate Restb.ai's technology across their platforms while retaining the Restb.ai brand. Clear Capital said the deal builds on its 2025 strategic investment from GTCR, which supported platform expansion and acquisitions.
