About Phase Four

Phase Four based in Hawthorne, California, is revolutionizing satellite propulsion with their innovative plasma propulsion system. The company, established in 2015, aims to address the most expensive challenge in satellite technology - propulsion systems. By eliminating common failure points in existing technologies, such as electrodes, high-voltage electronics, and complex fabrication, Phase Four offers a reliable, high-performance system that is also cost-effective and durable. Their propulsion systems provide Hall Effect Thruster performance at a fraction of the cost and delivery timeline, with nearly double the lifespan. Recently, the company secured a significant $6.25M in Debt Financing in an investment round led by LEONID on 13 March 2024. Phase Four's innovative approach to satellite propulsion presents an exciting opportunity for investors looking to support the exponential growth of satellite constellations. For professionals keen on contributing to this mission, Phase Four is actively hiring, with open positions available at www.phasefour.io/careers.
