About Us

Our purpose is to accelerate the digital energy transition​

At ENSEK, we're passionate about unlocking the greatest possible value for our customers, using our technology and operating principles. We've made it our mission to build the world's fastest evolving energy platform, so we can enable the mass adoption of new technologies to combat climate change and improve the customer experience.

Overcoming challenges together

Unlocking the potential of the energy industry with digital transformation


With ever-evolving consumer expectations, greater levels of competition, increasing regulatory pressure, and climate challenges, the need for energy retailers to continuously adapt to keep up with the pace of change is unprecedented.

Taken together, this has created a pressure cooker environment with several challenges: reducing cost to serve, delivering a step-change in the customer experience, and creating products that respond to consumer adoption and the energy transition.​

As a result, digital transformation is at the heart of every retail energy supplier's strategy. But the challenge is how to execute that strategy against the backdrop of such a complex market and often equally complex technology landscape – and fast.

ENSEK provides 100% cloud native software platforms that power digital first, customer-centric energy supply businesses.
