Mission
Where your challenge is redefined
Letsur sets a new standard for problem solving for the AI era.Many companies still rely on external experts or solutions to adopt AI,Results beyond expectations can only be achieved by strengthening internal capabilities that can be directly utilized and operated.To make this possibility a reality, Letsur works together as a strategic partner for businesses rather than just a solution provider.
Establish a long-term AI roadmap through customized consulting, and develop practical application skills through field-centered training.The AI integrated management platform “Staix” is added to this to lower technical barriers from AI design to deployment and operation.As a result, companies can define their own problems, develop and operate customized AI, and internalize AI.
Companies without a dedicated AI team will also be able to focus on improving key performance and metrics by strengthening their expertise and capabilities.Let's work together to help companies establish new ways to solve problems and create sustainable results based on internal capabilities.

LG U+ Representative
A research lab at KAIST AI Graduate School faced challenges managing multiple LLM APIs — from key control and budgeting to security. After adopting Letsur’s AI Gateway, the team centralized API management, automated access recovery for graduates, and gained real-time visibility into usage and costs. This transformation allowed administrators to move beyond repetitive management tasks and focus on research support and performance improvement.
Professor Jaegul Choo, KAIST AI Graduate School
To ensure stable chatbot operations, we initially considered using the overseas OpenRouter service. However, we ultimately adopted Letsur’s AI Gateway for its strong Korean customer support, organizational and governance management features, and excellent tracking capabilities. Today, the solution is used not only for chatbot operations but also for internal research experiments, and we are highly satisfied with its performance.
Seunghwan Jung, CEO, LionRocket
It felt like witnessing the future of workflow efficiency through AX firsthand. Today’s seminar was more than just a training session—it was an inspiring moment that gave us confidence our company can take a significant leap forward.
