POWW

Outdoor Holding Co

A creator of online marketplaces, this company runs GunBroker, an auction-style site where millions of registered users and federally licensed firearms dealers buy and sell guns and shooting gear — the platform itself holds no inventory. Entrepreneur Steven Urvan launched it in 1999 after eBay began restricting firearm sales online, and the company later sold off its ammunition-manufacturing business to focus purely on the marketplace.
