Letter acquires Pre-A investment from Stonebridge Ventures and KB Investment

Full-scale Entry into the Enterprise AI Market
Achieved 200% Year-on-Year Growth Last Year

Business AI transformation partner Letsur has secured Pre-A investment to strengthen its AI operations management capabilities and accelerate its entry into the enterprise AI market.

On the 2nd, Letsur announced, “Existing investor Stonebridge Ventures and new investor KB Investment jointly led this investment.” The investment amount was not disclosed.

Letsur has supported the adoption of AI by more than 100 companies across various industries, centered on its AI operations management platform Staix, which is a complete overhaul and advancement of the previous ‘LAMP’. Staix significantly lowers the technical and cost barriers companies face when adopting and operating AI. It is designed to enable stable AI operation and maintenance without professional developers, even in organizations handling large-scale data and complex processes. It also handles large-scale traffic.

The core competitiveness comes from a collaborative model focused on long-term operations management and continuous performance improvement, rather than a one-time solution. After adopting AI, companies may face difficulties in practical use due to staff shortages and increased maintenance costs, but through Letsur’s operations management service, they can operate AI services stably while reducing costs by more than 70% without AI specialists. Through ‘Able Campus’, companies can enhance their internal AI utilization capabilities and continue to benefit from the latest AI technologies with ongoing service updates.

Last year, Letsur achieved over 200% revenue growth compared to the previous year and secured a cumulative total of 150 customers. It has secured a customer base ranging from startups to large enterprises, achieving a high customer retention rate of over 70%. In the first quarter of this year, it already surpassed last year’s annual contract amount.

Existing investor Stonebridge Ventures proceeded with follow-up investment, highly valuing Letsur’s technology and business model proven in the market. New investor KB Investment also participated in this investment, focusing on high customer loyalty and the growth potential of the AI operations management market. Letsur plans to further strengthen its position as a specialized AI operations management company based on this investment. In particular, within the second quarter of this year, it plans to significantly enhance services that practically improve corporate business and expand AI consultant recruitment, extending its business areas to various industries such as finance, manufacturing, and distribution.

Shin Sang-rok, Senior at Stonebridge Ventures, explained the reason for the follow-up investment: “As AI technology rapidly advances, the biggest challenge companies face is shifting from simple AI adoption to continuous operation and management. Letsur has sufficient competitiveness in the AI operations management market, demonstrated by its technology verified by major domestic companies and high customer retention rates.”

Sim Kyu-hyun, CEO of Letsur, said, “The most difficult part for companies when adopting AI is continuous operation and performance maintenance. Letsur provides an integrated solution that takes responsibility for all stages from construction to operation and education. We will establish ourselves as a stable and reliable partner throughout the entire AI lifecycle of companies.”
