DeNA AI Link Begins Japanese Launch of AI Software Engineer “Devin” — Concludes Strategic Partnership with Cognition AI to Redefine Conventional Norms in Development —

TOKYO, JAPAN - July 2, 2025 - DeNA AI Link Co., Ltd., a subsidiary of DeNA Co., Ltd., has entered into a strategic partnership with Cognition AI, Inc., a company that develops innovative AI products. DeNA AI Link will be responsible for supporting the Japan launch of "Devin," an AI software engineer developed by Cognition AI, aiming for AI to collaborate as a team member.

■Background of the Strategic Partnership

As the shortage of engineers continues to be a challenge in Japan, there is a growing demand to leverage AI technology to improve the productivity of individuals and teams. Amidst this, significant expectations are placed on AI software engineers capable of autonomously developing as part of a team. DeNA began using "Devin" internally in February 2025 and observed substantial productivity improvements. This led to the current strategic partnership, aiming for further acceleration of its adoption and broader utilization beyond internal use.

■Transformational impact of “Devin”

By implementing "Devin," each engineer can gain an autonomous development team, increasing daily output. Development periods will be dramatically streamlined and shortened, enabling the development of more features with the same resources. This will dramatically scale up a company's overall development capabilities. Furthermore, "Devin" can generate code that previously required an engineer, even when a non-engineer provides correct instructions, thus expanding the scope of monozukuri.

■ Features of "Devin"

"Devin" is an innovative, autonomous AI software engineer that automates the entire software development process. Unlike traditional AI tools that primarily assist with coding, "Devin" can autonomously execute multiple integrated tasks, from code creation, requirements definition, design, coding, testing, and deployment, with high efficiency and accuracy. It can also perform tests after code changes and finalize them into a format ready for human review.

“Devin” can join communication tools like Slack, acting as a team member to autonomously perform tasks. By running multiple 'Devins' simultaneously, tasks can be distributed on a large scale and with flexibility, dramatically boosting the overall productivity of the development team.

Specific Features of "Devin":

• Requirements Definition: Understand development goals clearly based on natural language instructions
• Design: Design necessary project architectures and data structures, etc.
• Coding: Generate code according to instructions and fix bugs
• Testing: Test developed code and identify issues
• Deployment: Deploy the developed software into production environments
• Devin Wiki: A feature that automatically analyzes code repositories and generates a Wiki including architecture diagrams and documentation.
• Ask Devin: A feature that automatically understands the entire codebase and supports code investigation and development planning through dialogue.
• Devin Playbook: A feature that allows users to save and share templates for routine development task procedures, enabling anyone to reproduce them.
• Devin Knowledge: A feature that accumulates project-specific knowledge and rules, allowing Devin to automatically reference and utilize them when needed.

[Work Efficiency More Than Doubles with "Devin" Implementation]
Within the DeNA Group, "Devin" has already been pre-introduced. Numerous cases have emerged where internal operational efficiency has more than doubled, for example, in new service development, technical research, improving code quality, and automating routine tasks and development workflows.

■Comments

Seiichiro Sumiyoshi, CEO of DeNA AI Link:
“DeNA has declared its commitment to 'all-in on AI,' continuously challenging itself not only to improve internal productivity through AI but also to strengthen the competitiveness of existing businesses and create AI-native new businesses.
Having personally experienced its profound impact firsthand, I am confident of 'Devin's' revolutionary potential.
I am confident that its introduction marks a major turning point in operational efficiency in Japan and will be a catalyst for widespread adoption of AI technologies. Together with Cognition AI, we aim to transform conventional norms in software development.”

Scott Wu, CEO of Cognition AI:
“We are excited to expand into the Japanese market with DeNA, who we consider as AI thought-leaders within Japan. Combining DeNA’s extensive know-how in applications of AI across industries, along with their robust engineering infrastructure and network, we believe we can dramatically enhance engineering productivity in Japan.”
