People worth working for

Bill Gates tweeted on May 15th career advice on Twitter: "Meanwhile, surround yourself with people who challenge you, teach you, and push you to be your best self. As @MelindaGates does for me."

As far as I know there is no platform or website that highlights great people who fall into this category at companies. It's a rough idea, but would you look on a job website that highlights the people that you would work with and the boss that you would work for?
