Very intriguing. Does espresso and brewed pressure (1bar) coffee. Will use capsules, fresh ground. Only $250 for launch earlybirds. And, as far as I know the first coffee brewing machine for consumers to use induction heating.
Reminds me a bit of the ZPM machine, especially at the price point it's coming out at. I don't think that's realistic. But regardless, I am in for two units - an early bird $250, and the limited edition $700 one, the copper and brass and fancy wood one.
I'm trying to contact the company for an interview.

Nice find. Induction offers a lot of promise if done correctly, it provides much faster heating than any other tec out there. Properly sized, a small induction heater coil can take a 1/4 inch bar to red heat (about 1600 F ) in seconds. With that kind of heating power, good temp control is going to be needed. Keeping a HX tube at temp will happen very quickly so the biggest lag I see will be in the thermocouple, for example maintaining a temp of say, 240 F will require a system that can respond in millaseconds. The heat potential is there for steaming too, an induction powered thermo block should be able to flash steam water for as long as you want to steam, again depending on sizing, it should have no problem with steam volume either.
The biggest down side of induction is that only materials that react to magnets is usable but that does include some SS so I suspect that SS will be the choice. Also, induction is power hungry when on, even small ones for working metal require 50 amp connections at 220v. That will be mitigated by the much lower power requirement in an espresso machine though.
Very interesting project, I am going to need to take a hard look at it, likely with a buy in too :D

There are recent adaptations to induction technology that allow us to heat up non-ferrous metals including copper too. They are mostly using much faster switching of the field to get this capability. One could also create a system that has a less or non-effected outer tubing with a core of stainless that would heat the water inside the tube, but not the tube directly.
My guess is that this will take no more power to heat than a normal plug in induction heat hotplate + a heating element for the group?
I'm watching this with curiosity as I've always thought induction will finally get tamed someday to work like this. You probably need to know your input and output temps and have a customized power scale that will heat the water to the right temps. Steam would be possible, but perhaps that would take more plumbing and $. Version 2 for steam perhaps?
