About DCI

John Sinisi, Founder & Principal

I’m an inventor at heart. Whether it’s a new idea I want to bring to market or a fresh challenge from a client, I focus on elegant solutions to complex problems. I don’t just want it to work — I want it to be amazing. At Design Circle Inc., we’ve produced two market-leading toothbrushes, the #1 heart retractor, and the #1 safety needle on the market.

Over more than two decades, I’ve worked on more than 3500 products in 15 different industries. And I’ve learned from each and every one. We’re looking forward to working with you.
