Toxic culture and poor leadership from the top down

Pros

None that I saw while there.

Cons

CEO is the worst human ever. He hates sales people and thinks you should be grateful to work there. Dungeon-like work environment, poor leadership, no marketing dept, leads are a joke, no systems to work with, homegrown CRM is a joke with nothing but a bunch of duplicates, clock in and out, toxic culture from the top down, the compensation plan is a joke - no way to make money. No opportunity to advance AT ALL.

Pros

Nothing at all. Do not work here.

Cons

Worst company I have ever worked for. Do not fall for it. I wish I could rate it zero stars.
