All Software Development Services in South Korea
HEYHICOMPANY
(0 review)At HeyHi Company, we design UX/UI that solves real business problems — not just screens that look good. Our process runs from user research and information architecture to wireframing, UI design, and developer handoff, with a separate planning (STEP 1) phase up front to reduce risk before design begins. We specialize in complex, high-stakes interfaces: B2B SaaS platforms, multi-tenant dashboards, and enterprise services. That depth comes from delivering for clients like CJ ENM and Deloitte, and it's why our work earned Korea's 2024 ICT Award Grand Prize (Minister's Award) and a 2025 GDWEB Gold. What you can expect: a research-backed rationale for every decision, clean Figma files ready for development, and a team that embeds with you from day one. With offices in Seoul and Bangkok, we work fluently with both Korean and international clients.Looking for work in Software DevelopmentLocated in Seoul, South Korea (+1)From €1,000 for Software DevelopmentWorks in multiple industriesSpeaks English, Japanese(+1)11-50 membersSnailSecret
(0 review)Verifiable by construction
SnailSecret is a Seoul-based studio that builds AI into the core of how a company operates. We take the manual, document-bound, judgment-heavy work that runs a business — reviewing, reconciling, reporting, deciding — and turn it into systems that run with AI. The hard part is not the demo. Most enterprise AI looks impressive in a pilot and then goes unused, because no one trusts its output enough to run real operations on it. We solve that at the root. Everything we build is verifiable by construction: you can trace why any result came out the way it did, so the system earns enough trust to actually be used rather than quietly shelved. We work across the full range of that shift — assessing where AI belongs and what it will return, automating document and reporting workflows, building prediction and scoring models, and standing up assistants over an organization's own rules and records. One standard holds throughout: if a result cannot be traced back to its source, it does not ship. For the figures that carry the most risk, every value is checked against the original before deployment, and a single mismatch fails the build. Our work spans mortgage underwriting, legal, semiconductors, logistics and our own quantitative research platform. We are a small team from psychology, mathematics and computer science, so the person who builds your system is on the first call. And we would rather prove it than pitch it: give us twenty pages of your hardest process, and in two weeks we return a working system built on it — for you to judge, not just read about. Verifiable by construction. https://snailsecret.kr/Looking for work in Software DevelopmentLocated in Gimpo-si, South KoreaFrom €10,000 for Software DevelopmentWorks in multiple industriesSpeaks English, Korean1-10 membersUnicom Marketing
