From Swiitch to 


In 2018, we set out to solve the pain of updating our credit and debit card details with businesses who have it on file.


We’ve all been there. We lose a card, or it was stolen. Our current card expires, or maybe we change banks. Then, all that work begins to update everyone.

We've now solved for that, and that product is called Swiit.ch. 


On the way there, we realised we developed a revolutionary new platform for software.


So became the Unblocked Platform, which powers Swiit.ch and will a whole new generation of distributed applications.

Rapid delivery of secure smart, distributed applications.

Enabling cardholders to switch their recurring card payment details, in a snap.
