GIANTY

GIANTY was founded in 2000 in Yokohama, Japan as GNT, Inc., originally a mobile internet company focused on mobile content and e-commerce. It rebranded to GIANTY in 2017 and has since grown to over 350 employees across offices in Tokyo, Ho Chi Minh City, Da Nang, and Reston, Virginia. The company has delivered nearly 20 game IPs, collaborated with Square Enix on Final Fantasy XV and ENGI for Netflix anime content, and completed 690+ projects for 69+ clients. It positions itself on Japanese-standard quality checks and the ability to work across multiple time zones—teams in Vietnam and the US allow clients to receive project updates by the next day.

Services and capabilities

GIANTY operates across four main service lines: game development, art production, software development, and AI solutions.

For game development, the studio works across mobile, PC, console (including Switch), and web platforms. It uses Unity and Unreal as primary engines and also offers Roblox and game adaptation services. Clients cite "timely deliverables, stays within budget, and professional and responsive project management." One testimonial notes that after outsourcing app development and front-end tasks to GIANTY's Vietnam team, the client witnessed "a significant increase in the development need and growth."

Art production covers 2D design, 3D design, concept art, animation/VFX, UI/UX design, and graphic design. The team includes dedicated 2D and 3D design managers.

Software development services include app development, web development, maintenance and support, and DevOps implementation. The company also offers AI development through proof-of-concept R&D, custom AI development, and AI integration and optimization. A notable case study, GIANTY AI Tax, reduced document processing time by 70% for CPA firms by automating extraction of 14 IRS forms with 90%+ accuracy. The system used AWS Textract, Google Vertex AI with LLMs, AWS Lambda, SQS/SNS, S3, and RDS—processing documents through a seven-step pipeline: form detection, splitting, field mapping, extraction, normalization, validation, and Excel generation. Another project, Doraverse, is described as an all-in-one AI workspace that automates repetitive tasks. A third, the AI Classroom Analysis System, uses video analysis to track student engagement.

Notable work

Kioomon Origins was delivered to Kiooverse as a scalable Unity MVP in 90 days. Built with Unity 6000.0.40f1 and C#, it proved core gameplay mechanics and gathered community feedback. The project was a WebGL-based roguelike action-survival game available on PC and browsers, with iOS/Android ports in progress.

Ayakashi Tamashi, a mobile RPG, launched on iOS and Android. The company's earlier game Ayakashi (released 2012) achieved over 2 million downloads and localization in Korea and Taiwan.

Gokko World was a localization of Gokko Land, a Japanese educational game, adapted for Vietnamese audiences. The project launched in 2023 for iOS/Android and has been ongoing for one year, involving market research, translation, and cultural adaptation.

GIANTY also co-developed Lunar Pulse, a roguelite card game, with Fahrenheit 213 (launching on Steam in 2027).

How they work

The company operates across five time zones with cores in Japan and Vietnam. Clients consistently report strong communication and workflow despite the geographic spread, citing "the flexibility of our members in Vietnam" as a key factor. Project management includes real-time dashboard visibility (as evidenced by the AI Tax case study), centralized portals organized by client and tax year, and escalation protocols to the Japan office for issue resolution. The AI Tax MVP was developed with a single engineer and AI-assisted development tools within one month, suggesting a lean, tool-augmented approach. Pricing is described on the website as "accessible" relative to Japanese-standard quality.
