Josh Giegel founded Gambit in 2023 with the goal of

developing innovative, unique defensive capabilities at

unprecedented speeds at a fraction of today's cost.

Before founding Gambit, Josh served as a Co-Founder,

Board Member, CTO, and eventually CEO of Virgin

Hyperloop, a company developing a revolutionary new

mode of mass transportation. He co-founded the

company in his garage and built it to over 300 people

and raised ~500M during his tenure. He redefined what

was possible by rapidly developing, testing and

integrating over ten novel new systems into an integrated product, with a team generating

over 200 patents. He led the development and build of the first full scale Hyperloop system in

the world (DevLoop) integrating electro-magnetic (EM) propulsion, magnetic levitation,

control, vacuum, vehicle and tube systems.

Josh began his career at SpaceX as a Lead Analyst in the propulsion engineering group. He

successfully designed, developed and built the Merlin 1D family of engines, the first truly

reusable rocket engine ever built. He was the Lead Engineer on the microgravity fluidics for

the Dragon Cargo Spacecraft propellant tanks, ensuring mission success and first space

station docking. His novel engine design for the SuperDraco Dragon thrusters created a new

paradigm in design and pioneered the build and test of the first 3D printed thrust chambers

which are now common across the ‘new space’ industry.

After SpaceX, Josh served as the Lead R&D Engineer at Echogen Power Systems, building

and developing the first industrial scale (8 MW) waste heat recovery engine using a

supercritical CO2 power cycle in the world. This tool yielded the creation of 4 patent

disclosures for novel new power cycles which he developed into a variety of new applications

for CO2 heat recovery systems.

Josh holds an M.S. in Mechanical Engineering from Stanford University and a B.S. in

Mechanical Engineering from Penn State University
