The following presentation mentions something called "Garvey Space", and something bigger named "Super Strypi".
there are a number of odd things about this project. to begin with, the radially segmented tank design for a pressurized tank would seem to weigh more than a conventional cylindrical tank and minimum weight is critical for achieving orbit with a pressure feed launcher. next, why use methane instead of alcohol or kerosine. its lower density requires larger heavier tanks for a small isp gain. finally, using differential throttle for attitude control i can see for yaw and pitch control, but what about roll?
thanks for your response ed, all your points make sense. one more question, does anyone know if this group has done any test flights ? it takes alot more than a reliable engine to achieve controlled supersonic flight. look at all the challenges armadillo has had with their stig vehicle.
Nanosats, not ASATs

It would also allow, in theory, a way to provide dedicated (not shared) capability in a crises.Be all of that as it may, my interest in this thing is the attempt to create a small, cheap launch vehicle. There are some off-the-wall ideas here being attempted by some non-standard players. That's terrific. Also, and I'll just come out and admit it, I like stainless steel. - Ed Kyle
Attitude only could be done with CMG's
