Behind the scenes 03 | sofi stick
This week we want to share with you a few moments from the development of our sofi stick, including some early moments of the “sofi 0” or the “S0” - our very first concept of the sofi stick as well as the “S1” of which we are running a limited production for our Pioneers. Hope you like what you see! 
S0 | concept
The S0 concept sofi stick was a proof of concept that we can deliver a single formulation from a standard 10 ml bottle, count each press, and generate a data point that we capture through a bluetooth bridge. It was super basic in every way, hand made and 3D-printed parts, and we used existing standard electronics boards - but critically it proved that the sofi stick was doable (in principle, at least)!
S1 | development
Having proved the principles of the sofi stick with the concept S0, we then moved to creating a version that we could manufacture in the hundreds or even thousands to prove out the principles of sofi with Pioneers in the real world.
This required us to prepare sofi’s designs for manufacture, with the objective to create something iconic, simple and beautiful that we could see in every pocket, jacket or handbag, on the go. It was important to us for it to blend in well with other items (next to a mobile or set of keys), fit easily in a pocket or handbag, clearly display which formulation is in use without a Pioneer having to check the sofi app, and a number of other considerations. The other key requirement was that we wanted to move quickly in giving Pioneers a sofi stick they can use - so we had to think really hard about what was the minimum loveable product that could deliver our first formulation.
S1 | production
In order to manufacture and assemble our first 300 sofi sticks, a total of 3,494 individual parts are required, each with its own series of tests and validation processes!

Excitingly, our S2 sofi stick is already under planning. We will incorporate key learnings from our S1 Pioneer Program as well as some functional upgrades (such as rechargeable lithium cell) that we decided to roadmap to accelerate getting the S1 sofi stick as quickly as possible to you.
