Phase Four Secures $10 Million in Seed Funding to Revolutionize Satellite Propulsion Technology

We are thrilled to announce that Phase Four, headquartered in Hawthorne, California, has successfully raised $10 million in new funding to further revolutionize satellite propulsion technology. As a pivotal player in the burgeoning satellite industry, Phase Four is dedicated to facilitating the rapid expansion of satellite constellations by addressing the propulsion system’s most significant challenges—the cost and reliability issues associated with legacy technologies. By innovating beyond conventional designs, Phase Four has developed a propulsion system that eliminates common failure points, such as electrodes and high-voltage electronics, while simplifying the fabrication process. The result is a cutting-edge solution that provides Hall Effect Thruster performance at a dramatically reduced cost and with a significantly accelerated delivery timeline—nearly doubling the lifespan of traditional systems. This new round of funding will enable us to scale our manufacturing capabilities, expand our research and development efforts, and enhance our product offerings to meet the growing demands of the space industry. We are excited about the potential impact of our technology and are committed to making satellite launches more efficient and accessible. With this funding, we look forward to continuing our mission to enable the future of satellite operations. Interested in joining us on this journey?
