D1

What D1 does

D1 (디원, THE ONE CO.,LTD.) is a South Korea-based, privately-held Dassault Systèmes authorized partner specializing in product lifecycle management (PLM) and smart factory solutions. Headquartered in Busan with company registration number 375-86-01095, the company resells, implements, trains, and supports four core Dassault Systèmes products: CATIA (3D design and CAD/CAM/CAE), ENOVIA (PLM, BOM, and supplier collaboration), SIMULIA (multi-physics simulation including Abaqus, Isight, Fe-safe, Tosca), and DELMIA (digital manufacturing, production planning, and robotics simulation). Together these cover the full product lifecycle from concept through manufacturing and service. The company is led by Representative Director 최유진 (Choi Yujin).

D1 generates revenue through three streams: (1) software licensing and resale of Dassault Systèmes products on subscription/recurring terms; (2) professional services for implementation, structured training programs, and consulting; and (3) managed/technical support services delivered remotely with direct connection to Dassault Systèmes. Pricing is quote-based, billed annually, and targeted at enterprise customers. The go-to-market is direct enterprise field sales with four physical branches across Korea's principal industrial corridors — Seoul, Busan, Daejeon, and Changwon (the last doubling as a training academy) — supplemented by industry events such as the SIMULIA CST User Conference 2025. Customer segments are enterprise Korean manufacturers spanning automotive parts, automotive electrical components, construction machinery, aerospace, defense, and broader industrial equipment.

In July 2024, D1 announced a merger with EmaxTech (이맥테크), expanding capabilities in smart factory and digital transformation services and adding JAVA-based systems integration work. The company shows no external funding, no parent company, and no public listing. Operational evidence — active hiring of JAVA developers for smart factory projects, website launch in 2023, post-merger customer communications, and conference participation — indicates ongoing business activity, though financial scale (revenue, headcount, deal size) is not publicly disclosed.

Broad incumbents

• PTC: Vendor of Creo, Windchill PLM, and ThingWorx IoT platforms — a direct PLM/3D design competitor to the Dassault portfolio D1 implements. Relevant for understanding the competitive landscape D1 navigates in Korean enterprise deals.
• ANSYS: Engineering simulation software leader with multiphysics solvers directly competing against SIMULIA (Abaqus) in structural/FEA and CFD. Relevant incumbent in the simulation market D1 helps Korean enterprises adopt.
• HCLTech (Engineering & R&D Services): Large IT services firm with a dedicated engineering services practice covering PLM, CAD/CAE, and digital manufacturing implementations across Dassault, PTC, and Siemens stacks. Overlaps D1 in PLM implementation services but at much greater scale.
• Hexagon Manufacturing Intelligence: Provider of design, engineering, simulation, and metrology software (including MSC/Nastran, formerly MSC Software) competing against Dassault's SIMULIA. Adjacent incumbent in the manufacturing software space D1 addresses.
• Cadence Design Systems: Provider of EDA and system design software including thermal/structural simulation (via Numeca acquisition). Broadly comparable as an engineering software incumbent with simulation-heavy product portfolio intersecting SIMULIA's domain.
• Infosys Engineering Services: Global IT services major with engineering services arm delivering PLM, IoT, and digital factory implementations. Comparable to D1 in services scope (PLM/digital transformation) but operates at vastly larger scale across geographies.
• Siemens Digital Industries (DI Software): Vendor of competing PLM/MES suites (Teamcenter, Tecnomatix) that compete head-to-head with Dassault's 3DEXPERIENCE portfolio D1 resells. A relevant competitor/incumbent shaping enterprise software selection in Korean manufacturing.

Regional players

• LG CNS: Major Korean IT services firm delivering enterprise IT, manufacturing execution, and digital transformation to large Korean conglomerates. Comparable as a domestic Korean systems integrator competing for the same enterprise PLM and smart factory mandates.
• Samsung SDS: Korean IT services arm of Samsung Group with smart factory, PLM, and supply chain digitalization practices. Comparable to D1 as a Korea-based enterprise systems integrator addressing manufacturers' digital transformation needs.

Direct peers
