Aceso Plasma

Aceso Plasma, founded in 2016 and based in Virginia Beach, develops cold plasma technology for medical and decontamination purposes. The company is a subsidiary of MATBOCK. Aceso Plasma’s core product is the Aceso Plasma Device, a patented, portable, low-temperature device that generates oxygen plasma from ambient air to disinfect and accelerate the healing of wounds. This technology produces high concentrations of Reactive Oxygen Species (ROS) without harmful by-products like ozone or UV light. The firm's solutions also have applications for the decontamination of chemical and biological hazards from military equipment and personnel without requiring a water source. Another application is an air purification system designed to eliminate bacteria and viruses without replaceable filters.

The founding team includes President Zach Steinbock and CEO Sean Matson, both of whom are former Navy SEALs who graduated from BUD/S Class 258. Steinbock has a BS in Mechanical Engineering from the United States Naval Academy and attended Jefferson Medical School for three years. Matson holds a B.S. in Civil Engineering from Virginia Military Institute. Both are multi-time founders with previous successful exits. The leadership team also includes COO Brad Dumke, who has extensive experience in early-stage healthcare information systems, and CTO Dr. Spencer Kuo, a long-time professor at NYU Tandon School of Engineering with decades of experience in plasma research for DoD and NASA grants. The company's Chief Medical Officer is Dr. Greg S. Steinbock.

Aceso Plasma targets the wound healing and non-medical decontamination markets. Its technology is designed for both defense and civilian sectors. The company has been actively involved in securing government contracts, receiving SBIR Phase I and Phase II awards from the Air Force totaling over $1.5 million in 2020 to develop its Aceso Plasma Generator. In July 2025, the company closed an initial Series A funding round of $500,000 led by Stony Lonesome Group, a venture capital firm focused on veteran-led companies. This funding is intended to support clinical trials, regulatory processes, and production development.
