About Us

At ZeroKey we have one mission; to drive optimization through digital transformation. Our world is inherently analog, rendering most “things” invisible to the digital domain. ZeroKey is changing that, one factory, warehouse, and facility at a time.

Through our patented and breakthrough IIoT localization technology, Smart Space, ZeroKey is digitizing things that have never been digitized before. Driven by Smart Space’s millimetre-level 3D digitization accuracy, we’re bringing real-world workflows and processes into the digital realm like never before to power previously impossible digital solutions that redefine state-of-the-art.

ZeroKey is a venture-funded, high-growth tech company headquartered in Calgary, with regional offices opening soon in Toronto, Silicon Valley, and Stuttgart. Originally started in mid-2016, ZeroKey has experienced several consecutive years of tremendous growth on the order of 9,000% annually. Today, with 24+ core patents and products in use across an exponentially growing client list reaching over 15 different countries and 3 different continents, we are excited to be adding this new role to the team along with several others as part of our long-term growth plan.
