South Korea’s Naver and Kakao Embrace Dual-Stack AI Strategy

In a significant move for enterprise artificial intelligence, South Korea's leading tech giants Naver and Kakao have announced the integration of both OpenAI's ChatGPT and Anthropic's Claude Code into their internal tools. This dual-stack approach aims to utilize the unique strengths of each platform, providing employees with tailored AI solutions for various tasks. The shift highlights a growing trend in enterprise AI strategy, not just in South Korea but potentially across the Asia-Pacific region.

A Strategic Shift in AI Deployment

Naver confirmed its deployment of both AI tools within its operational framework, while Kakao plans to complete the rollout of Claude Code to all employees by the end of May. This deployment marks a clear division in AI responsibilities: ChatGPT will serve as the primary assistant for general tasks, whereas Claude Code is designated for software development. By adopting both, the companies aim to enhance productivity and allow employees to choose the most suitable AI tool for their specific needs.

This dual-strategy comes at a critical moment. Recent data from April 2026 revealed that Claude Code has surpassed ChatGPT in South Korea's paid generative AI market, indicating a shift toward more specialized AI applications in enterprise settings. With South Korea housing the highest number of paying ChatGPT users outside the U.S., its enterprise decisions could set a precedent for the broader market.

The Rise of Claude Code and Its Market Implications

The decision to employ Claude Code for coding tasks is supported by compelling statistics. According to Menlo Ventures, Claude Code captures approximately 42% of enterprise coding use cases, compared to ChatGPT’s 21%. This distinction has led enterprises to categorize coding as a separate procurement area, rather than merely a feature of general-purpose AI tools. An executive from a major Korean platform noted a significant increase in requests for Claude Code, attributed to its stable coding capabilities.

Claude Code's growth is remarkable, having experienced more than tenfold expansion within three months of its full launch in May 2025. Its appeal extends beyond engineering teams. Both Naver and Kakao view coding proficiency as essential for employees across various roles, including research and marketing, thus integrating coding fluency into the broader workforce.

Navigating the Dual-Tool Landscape

While the dual-stack strategy offers numerous advantages, it also introduces complexities in management, such as licensing costs and governance. To address these challenges, the companies are structuring AI tool deployments by role and task. This approach makes sure that employees are not left to navigate the use of two overlapping tools without guidance.

Both ChatGPT and Claude Code have been designed to meet strict data security standards, preventing sensitive internal data from entering model training processes. This compliance is critical, especially given findings from LayerX Security indicating that 77% of employees using unmanaged AI tools unknowingly share sensitive company information. Transitioning to enterprise-licensed versions of these tools reduces this risk while using the unique strengths of each AI offering.

The Broader Impact of Multi-Model Adoption

The dual-stack approach is not exclusive to Naver and Kakao. Other Korean companies, including travel platform Yanolja and ride-hailing service Kakao Mobility, have also begun integrating Claude Code into their operations. This trend aligns with a global analysis showing that 43% of employees worldwide now utilize multiple large language models for various tasks, with only 18% relying on a single model.

The implementation of both ChatGPT and Claude Code reflects a strategic response to the evolving AI landscape. By combining the strengths of distinct AI models, these companies aim to maintain flexibility and adaptability in a competitive market characterized by rapid technological changes and vendor offerings.

As AI tools become increasingly prevalent across industries, knowledge workers, regardless of their technical background, are expected to utilize tools like Claude Code to automate tasks and improve productivity. This shift may redefine the role of non-technical employees, equipping them with essential digital skills to thrive in an AI-driven economy.

Naver and Kakao's dual-stack AI strategy showcases a forward-thinking approach to technology integration and positions South Korea as a key player in the enterprise AI sector. Organizations worldwide are likely to monitor these developments closely as they shape their own AI adoption strategies in the years ahead.
