My favorite lost companies are:
1.Sutter Marketing - Sure they still do fast food, but I loved their big age compliance routes
2.Ritter and Associates - They have some work, but started paying less and less for age compliance and seem to have lost their big client in my area.
3.Service Check - Had an epic fine dining client who seems to have fallen off the face of the earth
4.Anonymous Insights - I've done the clothing store for the company who picked it up from them, shame, AI did it much better.
