Our mission is simple

create the finest products on the planet.

I started Prometheus alone in 2011, designing gear I actually used. As demand grew, so did the pressure—and by 2017, I brought on my first two full-time teammates, Joy and Gilbert. We're now a focused team of eight, still small but committed to excellence.

We don’t just make products—we rely on them. I don't trust any product made by someone who doesn't use it. That’s the difference. I’ve visited top brands where not even the owner uses their own gear. Around here, if it’s not in our pockets, it doesn’t go out the door. With 14 years of industry experience and customer feedback, we don't guess at what works, we know.

“The FourSevens Mini is still my favorite. It can put out up to 900 lumens in a package that’s not much larger than a chapstick.”

“The beta magnetic is an amazing light and in the role of a keychain light you won’t find better.”

“If you’re looking to step up your game and ditch the cheap earplugs you’ve been carrying around so far, the Prometheus Psi is a good place to start.”
