Value proposition
Uses a proprietary AI engine (trained on ~19M building public records + 8M exclusive-view data points) to analyze location and commercial district, identify undervalued retail properties, and calculate optimal purchase prices — then directly acquires and operates them, cutting out the complexity and time of traditional real estate transactions.
Products and solutions
Corner AI engine (property valuation/selection algorithm), Corner mobile app (direct purchase platform for retail property owners, 0% brokerage fee, 48-hour AI purchase-price offer, 1-week contract), Corner Space (premium shared offices at Yongsan Station, Konkuk Univ, Gwanggyo, Siheung), direct acquisition of undervalued commercial properties.
Unique value
AI-driven direct acquisition (i-buyer) model for commercial retail properties — AI selects undervalued assets and sets purchase prices, then the company buys and operates them itself, converting them into premium digital-first shared offices (Corner Space).
Target customer
Commercial retail property (상가) owners seeking fast, fee-free direct sale; startup founders and small businesses seeking premium shared office space (Corner Space).
Industries served
Commercial real estate / proptech, shared office / flexible workspace.
Technology advantage
Proprietary AI engine pre-trained on ~19M building public data and 8M exclusive-view data; AI analyzes location/commercial district to select optimal properties and compute purchase price; used successfully to win the Yongsan Central Park Tower bid from Seoul Transportation Corporation.
How they differentiate
Unlike pure brokerage/information platforms, Corner directly acquires undervalued commercial retail properties using its own AI valuation engine and operates them as premium shared offices — a vertically integrated AI i-buyer model rather than a marketplace.
