Nextchain

Nextchain is a multinational software development company founded in 2023, with offices in Yongin (South Korea), Ho Chi Minh City (Vietnam), Coquitlam (Canada) and Dover (USA). Projects are managed from Korea and delivered by our team in Vietnam, in English, Korean or Vietnamese.

We build functional products and operational systems, not template websites:

• SaaS platforms with subscriptions, permissions and analytics
• CRM, admin and business systems that replace spreadsheets and manual work
• Customer and partner portals connected to internal workflows
• iOS/Android apps (React Native, Flutter, Swift, Kotlin) with backend, admin and store release
• AI applications: RAG chatbots, AI image editing, AI analysis reports, multi-provider AI gateways
• API integrations, crawling and IT consulting (architecture, modernization, system takeover)

Our public portfolio includes 18 products, among them a government-support matching platform, an enterprise CRM with license management, an AI product-image editor for e-commerce, a survey operations platform, and our own AI products, NextAPI and 24hagent.chat.

How we work: understand the problem, design the right system, build and test in short iterations, then launch and operate. You get direct access to the delivery team, a visible backlog, regular demos and client-owned source code. Post-launch monitoring, fixes and feature work are available.
