Move fast

We break things and iterate

No status quo

Think first principles and be creative

Own it

Excuses don’t drive innovation–actions do

Our journey

TRL 3 & 4: Lab-scale prototype working

First run in the lab. We produced hydrogen and made first measurements on efficiency.

First team off-site at Hydrogen Expo

We visited Hamburg, Germany to learn about the industry and gain valuable contacts.

TRL 1 & 2: First concepts drafted

Patent filed in the Netherlands

After months of hard work, we filed the patent for our technological breakthrough.

Public announcement

As the engineering team keeps working on the prototype, we start sharing our progress publicly.

Innovation Grant

The Estonian Business and Innovation Agency awarded us a grant to cover patenting costs.

Baltic Impact Accelerator

In partnership with Estonian Cleantech Association, we got granted trainings and support for growth.
