FOC.uS History

That we have made, made us who we are



The world first consumer tDCS headset was made to scratch an itch and start the brain stimulation craze.



When you are new to hardware and think the obvious thing to do in the second generation is to add every possible function – welcome to V2.


When you realise that supporting a massive amount of features in firmware, software and support is an absolute nightmare, take a clean piece of paper from and start clean again.

Introducing Go Flow.


You want us to prove that stimulation works on the brain? Ok we’ll develop an EEG so we can measure and show it. We’ll get back to you with a date….


Product refresh? Yes, please. More power? OK. More modes? Great idea. Fix all known errors in the process? Better do!

Introducing V3 and Go Flow 4.

2019 & 2020

Can we make EEG fit in a space helmet, develop new passive electrodes and add LSL? Sure, why not?!



The best laid plans of Mice and Men. What to make of 2020? What to make in 2020.

Necessity is the mother of invention.


Lesson 1

Don’t make last minute firmware changes on your production line. If you must, then the amount of immediate testing will be inversely proportional to the amount of pain ahead.

Lesson 2

Stay on your production line from start to finish.  If a tree falls in the forest with nobody to hear it, does it make a sound? I don’t know, but a production line you are not monitoring categorically does not make a sound (or a product).

Lesson 3

Outsource with extreme caution. Just because a company claims to be a logistics expert does not mean they have the first clue about logistics or a second regard for your success.

Lesson 4

Customers do not like being ignored – there are no stupid questions. If you are so smart you should have explained it better in the first place.

Lesson 5

An online retailer should pay close attention to their online store. If something is not explained on the website it does not exist.

Lesson 6

If you have to make a mistake, try to make it a new mistake.
