Who We Are

The First.
The Biggest.
The Boldest.

RØHM Media pioneered cartop digital billboards in South Africa — and we've never looked back. What started with a fleet of 50 screens has grown into a network of 200 active digital displays operating across the Johannesburg and Pretoria metropolitan areas.

We pair our cartop screens with in-car WiFi portals, programmatic ad buying, and full experiential campaign capabilities. Your brand doesn't just get seen — it travels with your audience, reaches them inside the vehicle, and collects real consumer data along the way.

Traditional billboards are static. We are not.

In-Car WiFi & Experiential

Inside the
Vehicle.
Inside
the Moment.

Our in-car WiFi portal creates a captive, one-on-one advertising environment that no outdoor screen can replicate. Passengers connect for free — and your brand is the first thing they see.

Branded WiFi portal — "WiFi powered by [Your Brand]" creates immediate brand association the moment passengers connect.
First-party data collection — gather demographics, preferences, and consumer insights directly through the portal.
In-ride surveys — run short surveys while passengers are connected, generating actionable market research.
App download campaigns — prompt passengers to download your app directly from the WiFi portal.

Experiential Add-Ons

Go beyond screens. Our experiential packages let brands create a full in-vehicle brand experience that passengers actually remember.

📦
Product Sampling
Distribute small consumables directly to passengers during their ride — snacks, sachets, sachets, or trial-size products.
🪑
Headrest Cover Branding
Branded headrest covers keep your message in the passenger's eyeline for the entire journey.
📲
Sign Up & Convert
Drive sign-ups, subscriptions, or registrations directly through the in-car WiFi portal while passengers have nothing but time.
📶
WiFi Powered by [You]
Sponsor the in-car WiFi itself — every passenger who connects sees your brand as the enabler of their connectivity.
