On today’s episode of Pathfinder, we’re joined by Tim Ellis, the CEO and cofounder of Relativity Space. Tim was in his twenties when he started Relativity Space with cofounder Jordan Noone six and a half years ago.
Fast forward to today. Relativity’s 3D-printed Terran 1 rocket is at the pad in Cape Canaveral and an orbital launch is “weeks away,” Tim tells us.
Relativity also recently announced that it’s secured more than $1.2B+ worth of launch agreements for the forthcoming, fully reusable Terran R rocket. There are more customer contract announcements to come, Tim says. In fact, just since we recorded 12 days ago, Relativity announced a highly ambitious commercial Mars mission with Impulse Space.
Pathfinder is brought to you by SpiderOak Mission Systems, an industry leader in space cybersecurity.
What we cover in Pathfinder #fff9…a sneak peek
- Tim’s non-linear path into aerospace at USC, where he was part of the first student group to launch a rocket to space and interned back-to-back-to-back at Blue Origin
- Then, Tim and Jordan would go on to get accepted into Y Combinator, cold-email Mark Cuban, and successfully pitch their pre-revenue, pre-product startup to other big investors.
- Relativity is scaling headcount quickly. Relativity had 100 employees before Covid; it now has 850 and expects to hit 1,000 soon.
- The company is also ramping up production, having expanded into a 1M square foot facility in Long Beach, CA. “Our momentum towards Terran R is significant,” Tim says.
- We walk through the unique parts of Relativity’s rocket-making stack, from propulsion to reusability to additive manufacturing.
- 3D printing is “the holy grail of automation technologies for aerospace,” Tim opines, and Relativity’s 3D printing efforts span a few hundred employees. Eventually, the company’s 3D printers may be useful in other industries.
- We ask Tim how he’s navigating market turbulence and whether Relativity A) has taken a valuation haircut, B) will need to raise again soon, or C) if it ever considered going public via SPAC.
- Tim shares his thoughts on the economics of launch and where the market is saturated vs. undersupplied.
…and much more. Over the course of an hour, our conversation took us from writing novels and Fight Club to interplanetary travel and chilling on Mars with a Corona. We hope you’ll learn as much as we did.
