The team at sparrXOO are very professional, helpful & knowledgeable about all aspects of online business development for our clients (both small businesses as well large brands).
It's obvious that they really care to help their customers succeed! There were several times I called or emailed them with questions/concerns during my time working there - never felt like it was more than once every few months though :) They helped me build out some great campaigns across multiple channels which have been extremely successful so far!! We didn't work together long enough but when we did get started things went smoothly from start-to finish wtihout any issues along those lines either :D Highly recommend if you're looking into building your own paid media programmatic ad network!
