Klaxon is an audio advertising service that combines AI-driven content creation with media buying. It is designed for SMEs, marketing agencies, and service providers who want to reach audiences via radio, podcasts, and connected devices.
The platform offers two primary options: a DIY tool for advert creation and a fully managed service. The managed service supports script writing, voice talent selection, and the coordination of broadcasts across various media networks.
Buyers can target listeners using metrics including location by postcode, device type, and demographic interests. This is designed to allow more precise placement of audio ads compared to traditional broad radio broadcasts.
Before choosing Klaxon, buyers should determine if they prefer to manage their own broadcasting or if they require a managed campaign, as the pricing and workflows differ between these two options.
