Company-wide program empowers employees to build, experiment with, and apply AI in their daily work
More than 500 hands-on AI clubs launched across Toss affiliates, uncovering practical use cases from workflow automation to AI agents
Toss has successfully completed AI Surf Day, a company-wide initiative designed to help employees build, experiment with, and apply AI in their day-to-day work. Running from April through June, the program reflects Toss' broader vision of becoming an AI-native organization, where every employee, not just AI specialists,can confidently use AI to solve real business problems.
Rather than treating this as conventional training, Toss focused on applying AI to real work and scaling it quickly across the entire organization. To that end,  employees organized their own “AI Surf Clubs” every Friday, where they ran hands-on sessions building workflow automation, vibe coding, and various AI-powered tools. Over the 12-week program, employees across all Toss affiliates launched 509 AI Surf Clubs, and the initiative earned an average satisfaction score of 4.9 out of 5.
Moreover the program emphasized peer-driven learning over classroom instruction. Employees proposed topics, organized workshops, shared their own experiments, and introduced successful approaches to colleagues, creating a culture where AI knowledge spread organically across teams. As employees from different functions collaborated, practical AI applications quickly moved from experimentation into everyday work.
One standout project was an AI agent designed for junior account managers that applies game-like progression mechanics to employee development. The agent guides users through role-specific tasks while automating repetitive work such as drafting emails and searching sales materials. The project was recognized as one of the top entries in the Business Chapter AI Competition Workshop.
To further support AI adoption, Toss also appointed AI Surf Evangelists. A total of 142 employees were selected to champion AI within their teams by identifying new use cases, organizing workshops and meetups, and helping colleagues integrate AI into their daily workflows. The initiative enables each team to adopt AI in ways that best fit its unique responsibilities and ways of working.
"AI Surf Day marks an important step toward becoming a truly AI-native organization," a Toss representative said. "We will continue empowering every employee to use AI as a natural part of their work and foster a culture where AI helps us build better products and experiences for our users."

Toss partnered with OpenAI to host a day of hands-on AI learning, bringing together OpenAI experts and Toss employees to explore practical ways of applying AI to everyday work. Held as a special edition of Toss' weekly AI Surf Day program, the event combined expert-led workshops with a company-wide mini hackathon focused on building real business solutions with AI.
Hosted at Toss headquarters in Seoul on May 15, the event drew approximately 400 employees participating both in person and online, earning an average satisfaction score of 4.7 out of 5.
The morning workshops featured separate tracks for technical and non-technical employees. Developers explored how to automate software development workflows using Codex, while non-technical teams learned how to build AI-powered workflows with ChatGPT Workspace agents to streamline repetitive tasks. Both sessions emphasized live demonstrations, interactive Q&A, and hands-on exercises that employees could immediately apply in their own work.
The afternoon mini hackathon challenged participants to build practical AI solutions across two tracks: one focused on developing AI tools themselves, and another on applying AI to existing business workflows. Employees from engineering, business, and operations collaborated in cross-functional teams, spending two and a half hours building AI solutions designed to solve real workplace challenges.
Among the winning projects was an AI-powered menu classification tool for Toss Place that automatically categorizes thousands of merchant menu items each day, enabling richer analysis of industry trends and individual merchant characteristics. Another winning project introduced a developer tool that uses AI agents to automate coding and software validation, streamlining parts of the software development process.
OpenAI praised the quality of the projects produced during the hackathon, highlighting how participants quickly translated AI capabilities into practical business applications. In recognition of their work, OpenAI awarded ChatGPT Pro subscriptions to all participants, in addition to the winning teams.
The collaboration reflects Toss' broader commitment to building an AI-native workplace where employees are encouraged to experiment with AI and apply it directly to their work. The company plans to continue expanding hands-on AI programs and explore additional hackathon-style collaborations with OpenAI.
"Toss is committed to creating an environment where every employee can experiment with AI freely and apply it to meaningful work," a Toss representative said. "We'll continue investing in learning opportunities and collaborative programs that help turn employees' AI innovations into better products and experiences for our users."
