Worked with Xanthos for 2+ years with our construction business. Really noticed the increase in business. We are able to keep the pipeline full with the additional business that was drawn in, much of what led to high value contracts. It wasn’t a matter of monitoring hits/clicks but actually, what was the effect on the business.

I like to work with vendors who really bring something to the discussion, engaging fully in shaping the solution and challenging assumptions along the way if necessary. The team at Xanthos have always exemplified this approach.
