They also made a manual expresso machine, although I don't know if they continued production after the initial kickstarter run.

Their “Fulcrum” design looks quite similar to a Flair espresso. I mean, it isn’t a complicated concept (just a press), but the resemblance is noticeable.

And the "Helix" design looks just like the Aram espresso, a bit less obvious concept (a screw), but very similar.
