Who we are
Kara McMaster built it. The MDL team runs it every day.
I’m Kara McMaster, founder of MDL. Before MDL, I worked at Lamassu, where we ran 2.5 million dials a week.
My team starts the conversations and books the calls. You run the sales call and close it. I make my money when you close, through a revenue share.
