On today’s episode, we sit down with AJ Piplica, cofounder and CEO of Hermeus Corporation. The Atlanta startup aims to make hypersonic air travel a reality before the decade is out. AJ dialed into Pathfinder straight from the belly of the beast, i.e., Hermeus’s factory in Atlanta, which was abuzz with employees and machines whirling in the background. 

Today’s episode is brought to you by Altek Space.

What is Hermeus up to?

The Hermeus team is focused on shrinking the globe by developing the world’s fastest passenger aircraft. The timeline for that = 2029. In the meantime,  Hermeus recently selected Pratt & Whitney’s F100 turbofan for integration into its hypersonic engine, a move that the company claims will save it billions in R&D costs and years of schedule. 

Also in recent memory, Hermeus successfully demonstrated a turbojet to ramjet transition with its Chimera engine. Finally, Hermeus raised a $100M Series B last March to develop Quarterhorse and Darkhorse, its first and second hypersonic vehicles.

Among other things, AJ and Ryan covered:
— The startup’s origin story
— The roadmap: Chimera → Quarterhorse → Darkhorse → Halcyon
— What’s the state of hypersonics today?
— How the Halcyon passenger aircraft will be designed
— Derisking the business plan through iterative development and buying off the shelf
— Lowering the cost of aircraft certification
— Building in public and investing in marketing early on
— Atlanta’s talent density and Hermeus’s recruiting efforts
