Brennen Byrne is the CEO and co founder of Clef. At the age of 24, he is on Forbes 12 most impressive young entrepreneurs list. Clef is  Clef is a replacement for usernames and passwords. It recognize people by their phone instead of anything they need to remember or type. Walk up to any computer in the world, wave your phone, and you’re instantly logged in. They use the phone to do cryptography that makes logging in safer and easier. Essentially Brennen saw when LinkedIn had at the time the largest breach in history that there was a need for better online security. He and 2 college friends decided to try and make a difference to provide better security for everyone and make it easy. His company is currently booming out of Oakland California. What inspires me about this man, is that he on a whim, took 1 college course that essentially changed the rest of his life. He took a computer science class for a sense of what that actually entailed, and ended up liking it so much that he had the idea for Clef. What is inspiring in my eyes that it takes 1 thing to happen or 1 class in your life that really makes you ponder how you can make a difference and this is exactly what Brennen did.
