Charlotte, NC — Electromechanical engineering

Hardware design, prototyping & small-run manufacturing.

Start a project See our work

From napkin sketch to production — design, analysis, prototyping, and manufacturing under one roof.

Services

From first sketch to final run

Have an idea? We turn concepts into real, working devices and prototypes — bridging the gap from napkin sketch to hardware, and enjoying every step.

We're engineers with deep mechanical and electrical knowledge — curious, hands-on, and always learning. We love building, refining, and perfecting electromechanical hardware.

About

Time is your most valuable resource. Our job is to give it back to you.

Think of us as your extra set of hands — and minds. Whether you're a budding inventor or an established manufacturing firm, hand us your short, medium, or long-term projects and we'll deliver a product you can make better, cheaper, or for the first time.

Launching something new, revising an existing design, or troubleshooting a stubborn problem — we'll get you to the next stage of the product lifecycle, from conception to delivery and beyond.
