Simpli.fi

Simpli.fi is an advertising automation platform designed to help you manage high-volume digital campaigns with precision. Unlike traditional tools that rely on pre-packaged audience segments, you can use unstructured data to target specific behaviors, locations, and interests at the individual keyword or GPS level. This gives you more control over who sees your ads and how your budget is spent across CTV, mobile, and desktop.

You can streamline your entire workflow from media planning and buying to automated reporting and invoicing. The platform is built to handle the complexity of localized advertising at scale, making it a go-to choice for agencies and multi-location brands. By consolidating your programmatic, social, and search efforts into one interface, you reduce manual tasks and gain a clearer view of your cross-channel performance.
