Business Structure

OpenBoxAI operates an integrated model spanning Technology R&D, Game Development and Global Publishing. The three functions form a closed loop within the company, keeping core technology, content quality and market performance aligned.

01 — R&D

Technology R&D

Develops the Character Memory System, Procedural Content Generation, engine toolchain and data platform in-house, providing core capabilities to every product line. These technologies are used exclusively in the company's own titles.

  • Character memory and personality consistency
  • Procedural level and event generation
  • Content production pipeline and automated testing
02 — STUDIO

Game Development

Three in-house project teams work in parallel across narrative, simulation, card strategy, character-raising and casual puzzle genres, balancing long-term content-driven titles with lighter games.

  • Small, self-contained teams of 5–8 people
  • Playable prototypes validated before greenlight
  • Main story and core levels finalized by human designers
03 — PUBLISHING

Global Publishing

Delivers localization in 12 languages, multi-region user acquisition and live operations, with a focus on Southeast Asia, Japan & Korea, North America, Europe and the Middle East. The team also builds player communities and the creator ecosystem.

  • In-depth localization, including cultural and payment adaptation
  • Budget allocation based on LTV and ROAS models
  • Player community and content creator programs
