Inhan is a startup developing an enterprise AI agent operating system (AgentOS). It structures data and business rules scattered across internal corporate systems such as Enterprise Resource Planning (ERP) and Customer Relationship Management (CRM) into "ontology," a technology that connects the meaning and relationships of fragmented data. Based on this, it supports AI agents in making judgments about situations and performing actual tasks.
This investment will be deployed to advance AgentOS's data, process, and execution infrastructure. The company plans to enhance its technology so that AI can understand and accumulate not only the data and documents stored in the system but also the decision-making criteria and work methods of industry experts.
Dental Robotics, a startup developing autonomous suction robots for dental use, has secured seed funding from AI Angel Club, CNT Tech, People Investment, and DHP (Digital Healthcare Partners).
Dental Robotics assists dentists by supporting suction tasks during treatment. It aligns data from 3D CBCT (dental CT) and intraoral scanners to map each patient's oral cavity with 100-micrometer accuracy, while vision AI recognizes the intraoral environment—including saliva, blood, teeth, and gums—in real time, enabling a six-axis robotic arm to autonomously locate and position the suction device.
The alignment accuracy of 3D CT, scan, and vision camera data is 0.25mm or less, with a 98.6% alignment success rate confirmed across 210 test cases. For safety, the robot's end-effector is equipped with a pressure sensor capable of detecting forces from 50g onward, enabling it to judge avoidance and retraction based on contact patterns, along with a triple-layer safety structure including current cutoff functionality.
Choi Sung-ho, chairman of the AI Club who led this investment, said, "Dental Robotics is a startup aimed at solving the shortage of auxiliary personnel that dentists face directly in clinical settings." He added, "Given that dental clinics have high adoption rates of CT scanners and intraoral scanners, enabling spatial coordinate mapping, physical AI can quickly take root. We highly evaluate Dental Robotics' organizational capabilities, which are composed of experts in clinical practice, robotics, and AI fields."
AD Systems, a defense company specializing in small stealth unmanned aerial vehicles, secured Series A investment totaling 13 billion won. This round was led by LB Investment. Participating investors included Korea Development Bank, an institutional investor under policy finance, as well as Smilegate Investment, Future Asset Venture Investment, Future Asset Capital, Flux Ventures, and Inopolis Partners. With this investment, the cumulative amount raised reached approximately 18.4 billion won.
Established in 2019, AD Systems is a defense company that independently handles the entire unmanned aerial vehicle (UAV) development process, from gas design and composite manufacturing to flight control and avionics software development, as well as system integration. The field AD Systems focuses on is UAVs designed to enhance battlefield survivability by countering counter-UAS (C-UAS) systems. The company has developed technologies including low-observability (stealth) design and materials, VIO/SLAM-based non-GPS navigation, anti-jamming data links, and terminal-phase evasion flight techniques.
Its ability to internalize the entire unmanned aerial vehicle (UAV) development process, from design to production, as well as its track record of supplying defense-related products, influenced this investment. AD Systems recently secured a 8.7 billion won contract for an educational drone supply project aimed at training personnel for army drone operations. Previously, in July, the company was selected as a supplier for this project alongside Preneu and Aerux. According to the contract, AD Systems will supply a total of 3,792 units of the educational drone "AD-ME1" to designated army delivery bases.
Kim Jeong-ho, CEO of AD System, stated, "In the current Daejeon context, survival capability to penetrate enemy large-drone systems is essential, but drones that are too expensive and can only be deployed in small numbers are not a solution," adding, "The goal of this investment is to secure low-cost detection and anti-jamming technologies while achieving unit prices and Yangsan capabilities that allow for sufficient supply volumes."
Cardiovascular imaging AI startup Corologic has secured seed funding from Kakao Ventures and Seoul National University Technology Holdings. Corologic is a medical AI company established in May by the Circulatory Medicine Team Kang Si-hyeok (Prof.) at Bundang Seoul National University Hospital. The company is developing an AI solution called 'Angio-FILM' to reduce radiation exposure for both patients and medical staff during cardiovascular interventional procedures such as coronary angiography.
Coronary angiography and other cardiovascular interventional procedures are performed while monitoring X-ray fluoroscopy images in real time. As a result, both patients and medical staff who repeatedly participate in these procedures are exposed to radiation. AngioFilm is a solution that uses AI-based video frame interpolation (VFI) technology to restore coronary angiography images captured at low frame rates into high-frame-rate-like videos in real time. The goal is to reduce the amount of X-ray exposure while enabling medical staff to continuously monitor blood vessel movements and the procedural process.
Corologics plans to use this investment to proceed with clinical trials for institutional investors. It will prepare for entry into overseas markets by pursuing expanded approvals from the Ministry of Food and Drug Safety, U.S. Food and Drug Administration (FDA) 510(k), and ISO 13485 certification, an international standard for medical device quality management systems.
Jung Ju-yeon, senior analyst at Kakao Ventures, said, "Radiation exposure to patients and medical staff during coronary angiography has long been a challenge in the medical field," adding that "Corologic is a founding team with extensive experience in clinical care and medical AI businesses that has developed technology using generative AI to reduce radiation dosage by half while maintaining image quality."
Golden Brain Care, an AI-based language rehabilitation solution company, has secured seed investment from Series Ventures. Golden Brain Care develops and operates "Brain Friends," an AI language rehabilitation platform designed for patients with communication difficulties caused by neurological disorders such as stroke, brain injury, and dementia. Brain Friends provides integrated rehabilitation management services ranging from language function assessment to customized rehabilitation training, performance data analysis, and caregiver report generation.
Golden Brain Care is developing technology to quantitatively analyze patient voice, facial movements, and response data using AI. To ensure training and management continue even outside the therapy room, the company is also integrating on-device AI technology that processes data directly on the device to protect sensitive information such as voice and video. The service development is being led by on-site experts including Lee Hyeon-song (CEO), a Level 1 speech-language pathologist, along with the company's own corporate research institute.
Kwak Seong-wook and Park Jun-sang, representatives of Series Ventures, stated that "Golden Brain Care is commercializing the actual rehabilitation process based on the representative's on-site expertise," adding that they judged it valid to first demonstrate initial business viability in the public voucher and institutional investor markets before building capabilities in clinical trials and regulatory approvals.
