SteelSeries makes high performance gaming gear used by the most demanding, professional gamers worldwide and peripherals that provide superior quality and a competitive edge to gamers of all skill levels. What originally began with two people who recognized the need for superior, high-quality/performance gaming gear that would give gamers a competitive edge, has grown into a global leader in gaming and entertainment gear sought after for their high performance capabilities. Fast-forward to today, and they’ve come a long way since their first glass mousepad. They have global offices in North America, Europe, and Asia, providing an integrated portfolio of products designed specifically for gaming. Fueling Their growth is you, the gamer. While they are proud of Their technology and product innovation, They are even more excited about how these products are developed to meet the needs of gamers. Many companies may claim to develop superior gaming products but few actually do. Instead, they spend countless hours with lab engineers trying to force fit a new technology with bells and whistles and mediocre functionality for the end-user. At SteelSeries, they develop their products with a small internal team and a vast network of technology partners, channel partners, game publishers, and gaming communities around the globe. They aren’t afraid of being challenged and implementing new ideas. Their main goal is to always to listen to the collective feedback of Their professional gaming community. They won’t bore you with cheeky slogans, trying to underline their authenticity as gamers. They fully acknowledge that the best professional gamers in the world know more about what they want and what will make them better, than they do. They are proud to be working with their partners, but They can’t take credit for their invaluable input and feedback. Instead They tell it like it is: they help us. They want to know what works and what doesn’t. For this reason, SteelSeries creates innovative solutions that provide a competitive advantage for all gamers. Critical to their company’s success is also their reinvestment in the gaming communities and the individuals who support them. As a result, their corporate philosophy is to take a substantial portion of their revenue and put it back into the gaming community to help spur industry growth. They support their community in numerous ways, ranging from co-hosting tournaments like Iron Lady and King of the Hill, and supporting gaming competitions of all sizes, to promoting the top and up-and-coming gaming teams/organizations.
