The Blis platform allows you to geofence foot fall conversions and use custom polygons if you want to. I've done several campaigns using their self serve and it's pretty easy to work with. I'm pretty sure they built it on their own so it wouldn't be using simpli.fi based tech, based out of the UK I believe but they have a NYC office. Source: over 1 year ago

From what I found here they're just resellers. simpli.fi is basically the only company doing that goefence conversion zone tracking stuff that I know of in america. Source: over 1 year ago

One DSP that claims to specialize in hyper Geo targeting is simpli.fi. It says you can map out a geofence, but I'm not clear on the specifics on if they use 1P data or 3P, but worth checking into. Source: about 3 years ago

f5.com - there's tons of documentation to be found there, also "community" or whatever they call it there. So, lots of material one can well read and study ... And usefully a place to ask questions too. BIG-IP - see f5. Source: almost 2 years ago

I took the 101 and didn't like it; I have a lot of experience with LTM/GTM, but the test was so basic and non-technical, they ended up asking a lot of 'pointless filler questions' (like, what is the URL for f5.com website, where do you click on f5.com to access XYZ info, etc).
