What Cornerstone Interactive does

Cornerstone Interactive (코너스톤인터랙티브) is a South Korea-based B2B digital commerce agency founded in October 2002 that provides end-to-end digital services to large Korean enterprises. The firm's functional scope spans UI/UX consulting, brand identity design, e-commerce platform construction, e-learning system development, and mobile application development, with a customer base concentrated on major Korean conglomerates (Hyundai Motor Group, LG Electronics, Samsung, Lotte, Hyundai Department Store, SM Entertainment) and educational institutions (Sogang University, Chung-Ang University, Lotte Academy, visang Education). Its execution-oriented value proposition centers on sophisticated UX design, usability testing (heat map and eye tracking), W3C accessibility-compliant publishing, and multi-language global site capability demonstrated through engagements like LG Electronics Global Site and DN Solutions Global Homepage Renewal.

At its technical core, Cornerstone Interactive operates a proprietary commerce platform called CCS (Cornerstone Commerce Solution) Ver 1.0, iteratively built and validated through the firm's self-operated skincare brand Fimmm. CCS incorporates modular components including AMS (Admin Management System), ERP/DB integration, SSO/SCM authentication, and WMS modules. The technology stack is conventional web technology — jQuery, CSS3, HTML5, W3C accessibility standards — without disclosed AI/ML capabilities, public APIs, or developer portals. Notable technical capabilities demonstrated in client work include cashierless mobile payment via QR-code gating (Uncommon Store at The Hyundai Seoul), gamified e-learning with board-game progression mechanics (Sogang SLP), B2B pharmaceutical marketplace serving 17,700+ pharmacies (Ildong Shop), and same-day/dawn-delivery department-store grocery commerce (THE HYUNDAI SEOUL Food Hall to Home).

The business operates a project-based professional services model, deriving revenue from negotiated per-project engagements rather than disclosed pricing or recurring subscriptions. Customer acquisition relies on direct enterprise engagement via website inquiry forms, a downloadable company introduction PDF (CSI_CP_2026.pdf), and an extensive project portfolio showcase, with the firm offering Korean and English corporate websites. Pricing is not publicly disclosed. Cornerstone Interactive is wholly owned by Sogang University Technology Holdings (서강대학교 기술지주) since January 2010, an academic-affiliated holding entity, and maintains a wholly-owned subsidiary group comprising Pencil Co., Ltd., Design Stone, Marcus Alliance Co., Ltd., and Studio NOV. The firm does not disclose headcount beyond a "1-10 employees" firmographic range, has no public funding rounds, holds venture company and corporate research institute certifications, and has accumulated 20+ years of Web Award Korea recognition spanning 2012-2023 including multiple Grand Prix wins.
