What's more important than a deliverable? Nothing.


We love nothing more than to help innovators deliver what organizations need. We have a proven track record and enough craziness of making that happen, even under the most intense deadline pressure. We learn with you and help you when you need to develop ideas, validate with customers and scale-up with business partners.

From day 1, our main sponsor Pillar Project supports us and helps us develop a strong partners' network. Welcome Blockchain Israel, Blockchain HaSharon, Israeli Smart Cities Institute, 3iCampus and INT College!

Over the years, we served and work with dozens of cities in Europe and recently in Asia. Join us now, for developing citizen-centric services powered by the decentralized and open-source platform.
