Founded in June 2021 by Oh Hyun-ung, Step Lab develops space-grade mechanism technology including a launch-vibration-reducing separation ring used to connect and detach satellites from launch vehicles. Its flagship products include the separation ring and STEP POD, a CubeSat deployer that integrates an in-house vibration isolation system and is slated to fly aboard DaejeonSAT-1, giving the company its first flight heritage. Step Lab has expanded into payload technology, building a 4-meter-class, three-stage deployable SAR mesh antenna and developing an AI-based zoom optical module for space domain awareness through Korea’s Scale-up TIPS program. The company has also developed full small-satellite systems-integration capability via its DaejeonSAT-1 work, which will carry a selfie camera to confirm on-orbit status. With the recent Series A, Step Lab plans to scale mass production of its flight-proven mechanisms and accelerate global commercialization.
