[Edaily Marketin Reporter Soyoung Park ] This week (September 14–18), startups in various fields—including medical artificial intelligence (AI), content solutions, and content tech—secured investments from venture capital (VC) firms and accelerators (ACs).

In particular, “Enhance,” the developer of the AI agent that arranged Lee Sedol 9-dan’s first Go match against an AI in a decade, drew attention by successfully securing a large-scale investment. Earlier this past March, Lee Sedol held a discussion with Lee Seung-hyun, CEO of Enhance, at the Ara Hall in the Four Seasons Hotel Seoul—the same venue where he faced AlphaGo in 2016—and declared the dawn of an era of AI collaboration.

With this investment, Enhance plans to strengthen its agent OS technology to enable companies to actively utilize AI for decision-making and other purposes. It also plans to develop “Industry Packs” tailored for specific sectors such as manufacturing, finance, and distribution.

AI Agent Developer “Enhance”

AI agent developer Enhance has secured 51.2 billion won in Series C funding. Participants in this funding round included POSCO Technology Investment, LG CNS, Lotte Ventures, Timefolio Asset Management, StoneBridge Ventures, IMM Investment, KT Investment, and Hyundai Technology Investment. With this, the company’s cumulative investment has reached 81 billion won.

Enhance was founded in 2021. The company develops AI agent software necessary for businesses to utilize AI and provides software that enables comprehensive management of these agents. The company’s “AgentOS” helps businesses connect and utilize various AI technologies and AI agents with existing enterprise software, such as enterprise resource planning (ERP) systems. Currently, affiliates of POSCO, LG, and Lotte Group are utilizing the company’s software.

Cardiovascular Imaging AI Startup ‘Corologic’

Cardiovascular imaging AI startup Corologic has secured seed funding from Kakao Ventures and Seoul National University Technology Holdings. Radiation exposure for patients and medical staff during coronary angiography has long been a challenge in the medical field. Kakao Ventures took note of Corologic’s founding team, which has extensive experience in clinical and medical AI. The team developed technology that uses generative AI to halve radiation exposure while maintaining image quality. Kakao Ventures assessed that, as an independent solution not tied to any specific equipment manufacturer, it has high global scalability. They also expect the company to grow into a leading firm that improves hospital care environments through generative AI.

Corologic is a medical AI company established last May by a team led by Professor Kang Si-hyuk of the Department of Cardiology at Seoul National University Bundang Hospital. The company is developing “Angio-FILM,” an AI solution designed to reduce radiation exposure for both patients and medical staff during coronary angiography. Angio-FILM utilizes AI-based Video Frame Interpolation (VFI) technology. It restores coronary angiography images captured at low frame rates to high-frame-rate quality in real time.

Corologic plans to use this investment to pursue multi-center clinical validation. In addition, the company plans to sequentially secure 510(k) clearance from the Ministry of Food and Drug Safety (MFDS) and the U.S. Food and Drug Administration (FDA), as well as global quality certification (ISO 13485). Through these steps, the company aims to demonstrate the product’s reliability. At the same time, the company plans to lay the groundwork for domestic and international medical institutions to immediately implement the system on-site or collaborate with the company.

"Metalogi," a company specializing in immersive 3D content solutions

Metalogi, which operates "ON:展," a platform for managing and exhibiting 3D contests based on proprietary AI and 3D Gaussian Splatting (3DGS) technologies, has secured investment from CNT Tech. This investment was made through CNT Tech’s proprietary account. The investment amount remains undisclosed per mutual agreement between the two companies. CNT Tech took note of Metalogi’s leadership in driving digital transformation (DX) in both the public and private competition markets. The company highly valued Metalogi’s potential for explosive growth—spanning digital twins and the global healthcare market—based on its accumulated 3D data.

Founded in February 2024, Metalogy has established its proprietary AI-plus 3DGS pipeline, which reconstructs real-world spaces in real-time 3D. Its core service, “Onjeon,” is an online exhibition platform that transforms 3D design competitions—which were previously conducted primarily offline—into a web-based service. By integrating a 3D spatial information API, it enables users to instantly visualize competition sites in 3D from anywhere in the country. It automatically places 3D models submitted by participants onto actual terrain, providing one-stop support from multi-faceted judging to exhibition.

MetaLog plans to use this investment and acceleration program from CNT Tech as a springboard to accelerate the Onjeon platform’s entry into the public sector (B2G) market and its standardization nationwide. The company also aspires to become a global digital platform company that connects and monetizes reality in 3D—from physical spaces to the human body.

“Damgara,” operator of a video pre-production automation platform

Damagara, which develops “STORYSYNC Pro,” an AI multi-model-based video pre-production automation platform, has secured investment from CNT Tech. This investment was made through CNT Tech’s proprietary account. The investment amount remains undisclosed per mutual agreement between the two companies.

This investment was directed at promising content companies identified and nurtured through the “2026 Scale-Up Accelerating” program, organized by the Chungnam Content Promotion Agency and operated by CNT Tech. CNT Tech highly valued the fact that Damgara is a team equipped with a unique system capable of managing the complex decision-making processes and workflows of actual video production sites, going beyond mere AI prompt generation.

Founded in 2025, Dangara is a content tech startup that combines AI technology with over 20 years of accumulated expertise in commercial video and media art production. Its core solution, “StorySync Pro,” is an AI pre-production agency platform that manages the entire video production process—from planning and scriptwriting to storyboarding, shot design, video generation, and post-production editing—through a single workflow.
