Korean Defense AI Startups

StepLab, a Korean space-mechanisms startup led by Korea Aerospace University professor Oh Hyun-ung, announced on September 22, 2026 that it will jointly develop a 16U cubesat optical payload for space domain awareness with the US research institute SRI under the Korea Research Institute for Defense Technology Planning and Advancement's defense innovation global cooperation program. The payload combines StepLab's micro-vibration isolation technology with optical sensors and onboard AI for detecting and tracking objects in orbit. StepLab, whose products include separation rings, the STEP POD cubesat deployer, and deployable SAR mesh antennas, closed an 11 billion won Series A on July 31, 2026.

Microsatellite startup Naraspace Technology signed an agreement with the Korea Research Institute for Defense Technology Planning and Advancement on September 21, 2026 to lead development of an autonomous proximity-operations microsatellite under the Defense Innovation Company proposal program. The satellite will use an onboard camera and artificial intelligence to recognize objects, plan approach paths, and control its own orbit for inspection and rendezvous missions. The program is worth 6.7 billion won in total, 5 billion won from the government and about 1.7 billion won from private sources, and runs 52 months from September 2026 to December 2030.

ADSYSTEM (AD System), a Cheonan-based drone maker founded in May 2019 by former Air Force maintenance warrant officer Kim Jung-ho, closed a 13 billion won (~$9.9 million) Series A round announced September 16, 2026. LB Investment led, with KDB, JB Investment, Smilegate Investment, Mirae Asset Venture Investment, Mirae Asset Capital, Flux Ventures, and Innopolis Partners participating, taking reported cumulative funding to about 18.4 billion won after a 300 million won seed in 2024 and a 3 billion won pre-A round in August 2025. The company builds low-observable vertical-takeoff reconnaissance drones (the 15 kg AD-3000 in service and the 35 kg armed AD-4000 due in 2027) that navigate without GPS using visual-inertial odometry and SLAM, with anti-jam datalinks and evasive terminal flight validated in Agency for Defense Development tests. On July 30, 2026 it signed an 8.7 billion won Army contract for 3,792 AD-ME1 training multicopters, due by December 27, 2026 under the 500,000 drone warriors program. Proceeds go to a larger automated plant in Hwaseong and completion of the AD-4000.

South Korea's government plans to establish a 50 billion won venture fund for startups developing security-critical technologies, including AI, semiconductors, space, and defense applications, Seoul Economic Daily reported on September 5, 2026. The Ministry of SMEs and Startups and the Defense Acquisition Program Administration will each contribute 25 billion won, with the fund to grow beyond 200 billion won by 2030. Modeled on In-Q-Tel, the CIA's venture arm, the new institution will sit under Korea Venture Investment Corp. and invest roughly 2-3 billion won per company in early-stage firms with strong technology but unproven commercialization, prioritizing strategic value over financial return. Launch is targeted for mid-2027 at the earliest, pending National Assembly passage of a special act this year. The plan follows the February 2026 MSS-DAPA pledge to nurture 100 defense-participating startups and 30 "defense venture 100-billion-won companies" by 2030.

Airvility, the Seoul-based developer of the AB-U60 drone-carrier and hard-kill interceptor drones, closed a 6.5 billion won Series A on September 1, 2026 led by Silicon Valley venture firm Sage Partners, with Stonebridge Ventures returning and IBK Industrial Bank joining as a new shareholder. Cumulative funding now stands at 10.5 billion won. The proceeds will fund completion of its interceptor line — net-gun, direct-strike, and launcher-type aircraft — targeted for the first half of 2027. The company says it is in supply talks with nine countries across the Middle East, Southeast Asia, and Latin America and is targeting 50 billion won in cumulative revenue by 2028.

EGCED Tech, operator of the D4D (Deploy for Defense) platform, announced on August 28, 2026 a partnership with Korea Investment Accelerator to run a roughly three-month Oregon Defense Tech Base Camp for Korean startups in unmanned aircraft, autonomous systems, and robotics. Participants gain access to overseas flight-test environments through the Oregon UAS Accelerator, local industry partners, and university and defense-ecosystem networks in the state. The program directly addresses the regulatory and airspace constraints that limit drone and robotics testing inside Korea and builds on the Oregon MOU signed in Seoul in July after the D4D Hackathon.

Counter-drone and attack-drone maker Nearthlab listed on KOSDAQ on August 24, 2026 after pricing its IPO at the top of the range at 41,200 won per share, with institutional demand of 743.5 to 1. The offering raised roughly 37.5 billion won at an implied market capitalization of about 238 billion won. First-half 2026 revenue reached 17.4 billion won, seven times the prior year, and the company posted its first-ever quarterly operating profit in the second quarter. Defense accounted for 86% of first-half revenue, driven by a roughly 14.9 billion won Middle East shipment of the Jaiden (XAiDEN) swarm kamikaze drone, described as Korea's largest single drone export to date. It is the first defense-sector drone company to go public in South Korea.

Satellite-imagery AI company SIA and Myongji University opened a Defense AI Center on the university's Natural Sciences Campus on August 21, 2026, an industry-academia platform that pairs university research space with SIA's equipment to field-test and validate defense AI, geospatial intelligence, ISR, and unmanned-systems technologies. Founding participant startups include Nearthlab, Seadronix, Pablo Air, Alice Group, Pebblous, and NSM. The center is framed explicitly as a demonstration ecosystem to help defense startups validate products faster, addressing the shortage of realistic test environments that Korean defense-tech founders routinely cite.
