Meet Billy Broas, the creator of The Five Lightbulbs

Billy got into marketing in 2010, when he left his career at an engineering company to start his own business on the internet.

Since then, Billy has been the marketing brains behind some of the top online entrepreneurs and course creators. His clients include David Perell, Tiago Forte, Kimberly Snyder, and Ryan Deiss.

An introverted intellectual, and definitely not a "natural marketer," Billy saw an opportunity to create a tool for anyone who wears a marketing hat. Read more about Billy's story here.
