Moving on to the next phase

After 4 amazing years building Phase Four, I have decided to leave to pursue the next stage of my career. I have enjoyed leveraging my passion for bringing hard technologies out of the lab and to life. I am incredibly proud of the team and our accomplishments to date. Some of my favorites:

  • Bringing a never-before built technology to life as a commercial product.
  • Building a product compatible with the broadest range of spacecraft.
  • Growing from a guy at a card table to a 20-person team with a scalable product starting down the road to full production.
  • Demonstrating that in-space propulsion systems can be both high-performance and affordable, reliable, and scalable.

This is an important inflection point, and I have decided to hand over the reins of Phase Four to the capable hands of Beau Jarvis, who will lead P4 going forward. I will continue to serve as a Member of the Board of Directors and support the company in my new role.

I would like to express my genuine thanks to Shane Kelly, Stewart Alsop, and our other investors. In addition, to our customers, suppliers, and of course our employees, thank you all for supporting us in taking an idea and turning it into a business. Thank you!

semper in motu,
