My bullshit meter is through the roof. They talk about going to space, roasting there, how they'll do it, but they don't say why. They say:

To demonstrate the power of space technology and revolutionize the coffee roasting process

How does it revolutionize coffee roasting ? It's still a heat-based roaster. Nothing revolutionary.

Also IMO it won't taste good. They cool the beans, but how will they get rid of the gas? Right after you roast, the beans must be aerated so they lose their gas. The gas appears while the beans are roasted and it's why every roaster has a chimney. It's why coffee bags have air valves.

It all looks like a stupid cash grab.

edit: both founders seem to have no work experience related to coffee...
