Fast White Cat was quick to deliver on the online side of the campaign, only taking 6 weeks for the whole process. I'm not an IT person, but I knew exactly what I wanted to build.

When working online, we expect partners to be creative and active, identifying what our competition is doing and developing strategies based on that. I would expect Fast White Cat to be more active in some areas, but I'm very comfortable with how they approach our work.
