She is 837 podcast episodes into a conversation she started in March 2009, and she has not missed a Monday yet. Joanna Penn - also J.F. Penn when the lights go low - runs one of the world's most downloaded author-business podcasts from Bath, England. She does not work for a publisher. She does not wait to be chosen. She chose herself in 2006 and has been building the infrastructure ever since.
Penn publishes thriller novels under the darker pen name J.F. Penn - the ARKANE series, psychological crime novels, folk horror, dark fantasy - books where characters dig through catacombs and wrestle with mortality in ancient Jerusalem and modern London. She publishes practical author-business guides under her own name: how to self-publish, how to build an audience, how to use AI tools, how to make a living with your writing. Two brands. One woman. A dual identity she explains with a Plato metaphor: the white horse (outward, helpful, educational) and the dark horse (shadow, fiction, finally running free).
In September 2011, she walked out of her IT consulting job and never went back. That decision now has 14 years of compound interest on it: multi-six-figure annual income, a direct-sales bookstore, a Patreon with 1,400 paying members, and a podcast that has been downloaded in 229 countries. The number on the barbell at a British Powerlifting meet in 2024 was 190 kilograms.
She is not who you expect. She is quieter, more analytical, more strategic. She reads about death culture in her spare time - not as a morbid habit but as serious academic inquiry; she is currently completing a Masters in Death, Religion and Culture at the University of Winchester. She has two British Shorthair cats named Cashew and Noisette. She drinks gin and tonic and photographs cathedrals. When the AI writing debate erupted in 2022-23 and much of the author community chose outrage, she chose transparency: here are the tools I use, here is how I use them, here is what I call myself - an AI-Assisted Artisan Author.
The yellow card is still the origin story she returns to. An IT consultant in Brisbane, deeply unhappy, she wrote the affirmation on a card and put it where she would see it every morning. "I am creative. I am an author." She has published those six words more times than she can count - not as triumphant hindsight but as proof that you can begin from nothing true about yourself and work backwards into making it real.
