Long ago, Jim Gleick is sort of an example. Was a well-known science writer in the early 1990s, mostly for an excellent book called Chaos. He jumped onto the nascent internet train, starting an Internet Service Provider in NYC called The Pipeline, with a custom hardware and software stack (I wrote some of his software). This was around the time a soon to be very famous browser company called Netscape was getting started. He was successful and sold for circa 8 figures (big money back then) a few years later. He went back to writing after that. The startup wasn't directly in a subject matter sense related to his book work, but his intensity and curiosity and need to understand and make something were consistent across both endeavors. Hope that helps.
