I interviewed at a very successful startup last year that was basically doing the exact same thing as mighty. But they were selling it as primarily a security advantage (since its effectively an air gap computer) with additional advantages to performance.
The product itself was basically identical to Mighty. However, because it was marketed as a Security tool, they got customers from 9 of the 10 largest world banks, several government agencies, and so forth who bought licenses for every employee due to the security advantages that having an ephemeral server in the cloud provides. The companies enjoyed that there was also a performance benefit and they could skimp on physical workstations as a secondary benefit. But the product was selling licenses by the pallet load because of the security aspect, the performance was just a bonus.
Like I said, the product was effectively identical to what Mighty was doing. I think it was even younger than Mighty and was vastly more successful due to its market positioning.
