ABOUT US

In the 1800s Thomas Edison invented the light bulb.

Before that, it was dark. But with a flick of a switch, people could see, understand and begin to innovate in ways that would forever change the way we live. Think LED lights monitoring our health, Artificial Intelligence moving into the workforce, microwaves heating up your dinner…even space travel. And – yes – the internet. 

Since the invention of the light bulb, things have been less gloomy, but we’ve also picked up the pace.
We’re moving really fast: There are over 1 trillion photos taken every year and more content gets uploaded to the web in a day than was generated in the past decade. Intense. The internet of a million, billion, trillion things can be a scary, dark place for brands.
That’s where we come in. 

“Lumen” is the measure of visible light emitted from some source. Think of LUMEN Digital Marketing as your own personal internet light bulb, illuminating all things digital. We take data and simplify it to connect you to the most relevant prospects online.
We help you maximise your ROI and grow your business. Simple.

Within the digital environment, the more you dig the more you will find. We’ll help you understand these intricacies and the finite detail where the devil lives. The smaller the area the brighter the light, and the higher the Lumens. 

At LUMEN we’re inspired by the potential of digital.
Let us switch on your online presence so you can shine.
Edison would want it that way.
