Is your business under new ownership? These entrepreneurs who bought existing businesses share how they made updates while keeping loyalists happy.

Case study: Chris Baggott, new owner of The Mug, Greenfield, Ind.

Why buy? “We started Tyner Pond Farm [and were] selling out of pasture-raised pork chops, bacon and steak — but were left with a surplus of lesser cuts such as ground beef. The idea with The Mug was to give us an outlet for all that stockpiled hamburger.”

What was your vision? “It shifted from ‘How do we move our surplus hamburger?’ to a place where we captured the heritage of an Indiana drive-in, but with a modern farm-to-curb spin and recipes that are both familiar and special.”

How’d you approach changes? “People had so much nostalgia for the place, we wanted to keep the drive-in vibe. My mother-in-law and others volunteered to be carhops, like in the ’50s! The old restaurant had a Facebook page, so we explained what we were doing and why. The respect from fans translated into engagement.”

Can you please everyone? “Many think ‘local’ or ‘farm to table’ is just for wealthy people. But because we’re vertically integrated with our farm, we’re able to keep prices competitive. Our signature quarter-pound burger is only $4.75, comparable to $9 from a traditional outlet. About 40 percent of our customers don’t even live in Greenfield.”
