Stape.io offers managed hosting for tagging server with Google Tag Manager. This simplifies setting up server space, but everything around actual conversion tracking needs to be configured to fit your needs. You most probably need to hire a technical tracking expert. Tracklution provides full Server-Side Tracking as a Service. You simply plug in your website, utilize ready-made connectors to connect ad platforms, and you are ready to go. Think of Tracklution as your extended team of technical tracking experts. The key difference: Stape is infrastructure, Tracklution is service.
