"ReachFire Agency."- This is the secret phase you mention.
MediaMath, Turn, DataXu, X+1, TradeDesk are the popular vendors- sell DSP technology. As per my understanding you wish to enable few of the DSP vendors with your system and put the data into a dashboard or spreadsheet. This is the requirement.
As per my knowledge, MediaMath leverage a suite of third-party applications and internal databases to pull informations on platform usage, feature usage and performance. Here are few tools that I can use:
Google Analytics: Using this, I can track site-level data such as number of page-views, time spent on site, most popular browser, etc. Event traking is possible using this also. But this is not a plug and play tool- need development work for each and every event, you wish to track.
Heap Analytics: This is another option. It allows you to track all of a user’s click events (like clicks on buttons, mis-clicks, etc.) happening within your app by just adding a few lines of JavaScript to your app.
Even Internal database can be used. Mediamath internal database store data about campaigns, Client orgs and spend among other things. The problem is that a lack of a central, easily consumable repository for all of that data. But can be managed.
So this is all for Mediamath. I will take the most suitable- but you can also let me know if you have other preference.
Now I am curious to know exactly which DSP platforms you wish to enable with your required dashboard. Waiting here.
