In 2016, Brady Simpson founded Simtek to build reliable hardware and protect what people love. As a Virginia Tech alum, he understands the dangers of weapon misuse, but also the challenges of adopting restrictive technology. Simtek was created to offer technology-based products that monitor spaces without connectivity or power limitations and without infringing on usage or rights. Simtek supports the Second Amendment.
Simtek is a global team of 10+ people. We value engineering excellence, entrepreneuriship and the American dream.
We have decades of experience building hardware and software. We come from a diverse background and ultimately care about building the reliable products.
More than 2 years of research and development for our sensor. We've interviewed hundreds of people and built hundreds of prototypes, and tested with over 100 customers around the world. We always have more to do to make it better. It never stops!
