Small Business Spotlight: I Do Now I Don’t

Who: Josh Opperman, 35, founder, @IDoNowIDont

What: An online site for buying and selling pre-owned jewelry, mainly engagement rings

When: 2007

Where: New York City

How: Opperman’s own broken engagement is what got him thinking about the premise of his business.

“I had a lot of problems trying to sell my ring back,” he said. “The only thing I could get was a credit to the store, which wouldn’t do me any good with such a huge purchase. It wasn’t an option I wanted to take.”

Today, I Do Now I Don’t is a safe place for customers to buy and sell their pre-owned jewelry and engagement rings. Opperman said transactions are held in escrow until a certified gemologist checks out the jewelry.

Quote from the owner: “People definitely relate to what happened to me and I think that helps as well, knowing the founder of site went through the same thing,” he said.
