We started with wire.
We built a standard.
“We believe in technology. We believe everyone should have access to good services.”
We started behind the walls. Now we set the standard in front of them.
In 2009, DeMarkuss Day started pulling low-voltage cable through commercial office towers and luxury hotels, the precision work behind the walls that nobody sees and everybody depends on. In 2012, that obsession with craft became Cognito Media Services.
Over 14+ years, Cognito has grown from a single toolbelt into a trusted installation partner for retail giants like Nebraska Furniture Mart (NFM) and Best Buy, delivering more than 2,847 white-glove installations with a flawless 5.0-star reputation.
“When you master how hardware, wiring, and software interconnect in the physical world, creating seamless experiences becomes second nature.”
We don’t cut corners.
No cords dangling, no technology treated as an afterthought. Every home we enter is treated like a showcase.
Accessible Excellence
Everyone deserves good services. Whether you need a single 55” TV mounted flush or a multi-zone Dolby Atmos home cinema, our standard never changes.
Commercial Rigor
We learned our trade wiring hotels and commercial facilities. We bring laser levels, stud-center anchoring, in-wall rated cabling, and clean thermal management directly to your living room.
Proprietary App & Speed
No phone tag. We engineered our own iOS and Android client applications so you can schedule instantly, track your technician live, and manage every installation in one verified place.
The path from wire to intelligence.
True craft isn’t built overnight. It’s forged over thousands of hours on ladders, in crawlspaces, inside commercial server closets, and building digital operating systems.
