Nexkey is a multiple award-winning IoT tech startup company in Silicon Valley focused on designing access control devices for the SMB market and beyond. How we access physical spaces hasn’t changed or significantly improved for hundreds of years – we still use keys. Nexkey is the first company on the market to resolve the issue of providing “keyless” access to ANY physical space (not just doors!) with the advent of their three industry-changing wireless products that have completely revolutionized the access control space. What makes the company a unique differentiator in the market? Other companies focus on designing “smart locks” for homes and apartments in the consumer market, while others focus on wireless devices specifically for large enterprises that are cost-prohibitive, have a lengthy install-time and require traditional hard-wiring. Nexkey has designed commercial-grade access control solutions that install in minutes, are wireless (no costly hard-wiring required) and are highly-affordable at only 30% cost of other comparable products. Nexkey is at the forefront of a massive market opportunity to improve how people around the world access any kind of physical space beyond just doors.
