AI Agent Startup Era: At Ralphton, co-hosted by Kakao Ventures and Team Attention, participants won first place without touching their keyboards as AI agents wrote 100,000 lines of code. "The scale-up barrier for solo developers has completely collapsed," said Dongwook Jang, director at Kakao Ventures. "We are entering an era where we must meet founders with new profiles."

AI Infrastructure Cost War: SK Telecom signed a tripartite MOU with Supermicro and Schneider Electric at MWC 2026 to shorten AI data center construction timelines. Japan's NTT presented a vision to reduce data center power consumption to one-hundredth of current levels by 2032, signaling intensifying competition over AI infrastructure costs.

Startup IPO Acceleration: Electric vehicle charging infrastructure operator Chaevi filed a securities registration statement and initiated IPO procedures for Kosdaq listing. Genome-based drug developer Canap Therapeutics recorded a 962.1-to-1 subscription ratio in its demand forecast, setting its offering price at 20,000 won, the upper end of the desired range.

1. Humans Sleep While AI Codes Through the Night: 'Ralphton' Arrives in Korea

Developer community Team Attention and Kakao Ventures hosted "Ralphton" in Seoul, a hackathon where participants provide only ideas and blueprints while AI agents code overnight. The winning team never touched their keyboards throughout the competition, having AI agents write 100,000 lines of code. Before development, they conducted 133 rounds of Q&A between AI agents to minimize design errors and ambiguities. OpenAI sponsored the event, and developers from Singapore attended in person. "How deeply companies internalize AI agent utilization will become their true moat," emphasized Gubong Jung, developer at Team Attention.

2. "Anyone Can Easily Build AI Agents": KT Unveils 'Agent Builder'

KT unveiled "Agent Builder" at MWC 2026, a platform enabling AI agent creation through drag-and-drop without development knowledge or coding. Users can combine pre-built work templates and conversation modules to handle everything from defining use cases to data connection, response configuration, and deployment. Real-time log analysis and performance monitoring are also available after completion. KT is preparing industry-specific templates based on agent scenarios validated in finance, manufacturing, and public sectors. "Traditional AI agent adoption required significant development burden, but Agent Builder enables business process automation without complex development," KT stated.

3. 'God's Eye' 500km Above: Identifying Your Car's Color from Space

Domestic ventures' satellite image analysis technology can now identify vehicle types and colors from hundreds of kilometers in altitude, with AI integration rapidly lowering barriers to use. Korean companies including Telepix, Hancom InSpace, and SIA are embedding AI agents into satellite image analysis platforms, enabling analysis through simple commands without complex functions. This expansion is expected to extend satellite image applications across climate change response, agriculture, fisheries, energy resources, real estate, and logistics. "AI innovation is essential for processing satellite images that increase by thousands daily," emphasized Taegyun Jeon, CEO of SIA.

4. From Expansion to Cost Reduction: Shifting AI Infrastructure Competition

The AI industry's data center competition is shifting from expansion to cost reduction. SK Telecom signed a tripartite MOU at MWC 2026 with Supermicro and Schneider Electric to adopt "prefab modular" methods that pre-manufacture power, cooling, and IT infrastructure in modular units. SKT also partnered with domestic fabless startup Panesia to improve GPU connectivity. Japan's NTT announced a vision to reduce data center power consumption to one-hundredth of current levels by 2032 through "IOWN," a next-generation optical communication technology that processes data using light. AI infrastructure operational efficiency is emerging as a critical challenge across industries.

5. Chaevi Files Securities Registration, Ready for Kosdaq Debut

Electric vehicle charging infrastructure operator Chaevi filed a securities registration statement and initiated formal IPO procedures for Kosdaq listing. The company is offering 10 million shares at a target price range of 12,300 to 15,300 won per share, with maximum proceeds of 153 billion won. Chaevi directly owns and operates approximately 5,900 fast-charging stations, the highest among domestic private operators, and has maintained about 60% market share in government-led public fast charger construction projects since 2017. IPO proceeds will fund charging technology advancement including "5-minute charging," expansion of multi-purpose charging cultural spaces "Chaevi Station," and global market entry.

6. Canap Therapeutics Sets IPO Price at Upper Band of 20,000 Won with 962.1:1 Subscription Ratio

Human genome-based innovative drug developer Canap Therapeutics recorded a 962.1-to-1 subscription ratio in its demand forecast, setting its offering price at 20,000 won, the upper end of the desired range. Among 2,327 domestic and international institutions participating, 99.88% of total requested volume indicated prices at or above the upper band. Final offering proceeds total 40 billion won, with market capitalization of 259.1 billion won at the offering price. Notably, 76.1% of total requested volume committed to mandatory holding periods of 15 days or longer, the highest level since last year's revision of "Regulations on Securities Underwriting Business." Canap Therapeutics plans to conduct public subscription on March 5-6 and list on Kosdaq on March 16.
