HeyHi Company is a Seoul-based creative design and development studio, with an additional office in Bangkok, serving B2B and enterprise clients across Korea and beyond.

We combine UX/UI design, design consulting, web and mobile app development, and B2B SaaS and CMS platform engineering in a single team. That structure lets us take a product from strategy and design through to production without the handoffs and misalignment that slow most projects down. We specialize in complex, high-stakes work multi-tenant SaaS architecture, OTA and payment integrations, analytics dashboards, and enterprise web systems as well as 3D motion graphics and advertising video production.

Our process starts with a dedicated planning and architecture phase to define scope and reduce risk before design or development begins. From there, we move through UX/UI, prototyping, iterative development, QA, and launch, with transparent communication at every stage. In the early phase of a project, we often embed directly with our clients to minimize miscommunication and keep delivery on track.

This approach has earned the trust of leading organizations, including CJ ENM and Deloitte, and national recognition: Korea's 2024 ICT Award Grand Prize (Minister's Award), a 2025 GDWEB Gold Prize, and a 2023 Good Design (GD) Award from the Korea Institute of Design Promotion.

Whether you're an enterprise modernizing a platform or a company launching a new digital product, HeyHi delivers work that is scalable, maintainable, and built to perform for both Korean and international audiences.
