Rescale - Looking for insights

I got contacted by a company called Rescale, I don't have any clue about them, but they claim to be awesome and invested by Jeff Bezos among others. Does anyone have real insights about them? I have been researching about what they do (HPC), but I can't find anything telling me they are special or the next tech boom. It actually looks like another company trying to get a piece of a cloud market already canibilized by a few.#tech
