About Us
What started with a frustration, became a solution.
Dark Line was founded in 2019 by a small team who kept seeing the same problem: large sites, running expensive infrastructure, with no real visibility into what was happening or why. Bills arrived. Nobody knew what drove them. Faults developed. Nobody saw them coming. The instinct was simple. If you can measure it, you can control it. If you can control it, you can optimise it. That instinct became a platform.
Over 30+ business trust us
What we've become
What started as a focus on energy has grown into something broader. We now build intelligent infrastructure management systems for large-scale operators across South Africa, connecting geysers, air conditioning, lighting, electrical loads, and any other system that can be measured, to a single platform that gives operators real control.
150+ Sites
Measured, controlled and optimised using Dark Line products and solutions
2000+ Geysers
Connected, monitored and intelligently managed through the Gecko Hub platform.
Our Values
What we stand for
Four things guide every decision we make, every system we design, and every site we deploy. Not as words on a wall.
As the standard we hold ourselves to.
Driving Innovation Forward
We build technology for environments that don't stand still. Every product we design starts with a real problem, and every solution is measured by whether it actually works in the field, not just on a spec sheet.
Committed to Excellence
Uncompromising standards in everything we engineer, deploy, and support. We don't cut corners on the systems our clients depend on.
Ingenuity
Real-world problem solving through purposeful technology. We build for the environments our systems actually operate in, not the ones on a spec sheet.
Why us
Built for this market
Most infrastructure technology is designed for stable grids, predictable tariffs, and markets where loadshedding isn't a daily operational reality. We know different.
What others miss
An unstable grid as a daily operational reality
Infrastructure running across large sites with no central visibility
Solar that underperforms because nobody manages the load
The value of local presence when something goes wrong
What we know
How to design systems that perform through grid instability
How to give operators a single view of everything on their site
Where the waste is hiding, and how to act on it
That when something needs fixing, we can be there
