Signature 4 helps brands move from concept to completion. Through thoughtful design, precision engineering, and refined finishing, we create products built to perform and made to last.
Start a ProjectA blessed business with the spirit of a dedicated surfer — finding the hot waves, paddling out against the push, and riding every opportunity to the finish.
GO INTO THE WATER WITH NO FEAR. PADDLE OUT AGAINST THE RESISTANCE AND SURF THAT WANT TO PUSH US BACK TO SHORE.
We aren't surfers and don't claim to be. We're Designers, Engineers, and Finishers. We worry less about straight-edge perception and care more about following our passions.
Signature 4 started in Coldwater, Ohio as a custom badge shop tucked into a single warehouse rack. That was the whole operation. A few clients, a handful of people, and a lot of ambition.
“We’re all in this ride together. Ideas, leadership, creativity, exploration, innovation — all products of our people.”
Twenty-five years later the resume looks different. 750+ clients. 90+ employees. Four distinct manufacturing disciplines. But what hasn’t changed is the attitude — the small-town work ethic that shows up in every part we ship and every customer we answer for.
We treat each other like friends and neighbors. We think bigger, but we stay grounded. That tension is the whole thing.
