His philosophy of continuous learning drives him to explore new ventures, including his latest project, Poka Snack, a banana skewer product designed to simplify freezing and eating fruit. ## Poka Snack’s Kickstarter Success Launched on Kickstarter earlier this year, Poka Snack has already raised over 90% of its $4,000 goal. Brown’s innovative skewer design, featuring patent-pending semi-helical geometry, aims to solve the challenges of existing frozen fruit products. The project has also garnered over 14,000 TikTok followers, showcasing its growing popularity. ## From Medicine to Entrepreneurship Brown’s career spans decades, from graduating from the University of Michigan’s medical school in 1980 to serving as a professor and director of clinical nuclear medicine. After retiring in 2020, he joined the University of Utah School of Medicine and later a health-tech startup, Covera Health, as chief health strategy officer. ## Embracing Risk and Failure Brown’s entrepreneurial journey began during the dot-com boom, where he launched several internet ventures, including websites for textbook sales and cancer patient education. Despite some failures, he learned to embrace risk and not fear looking foolish, a mindset he applies to Poka Snack. ## AI-Powered Solopreneurship Brown leveraged AI throughout Poka Snack’s development, from product design to marketing and business planning. This technology enabled him to operate as a solopreneur, managing nearly every aspect of the business independently. AI-generated concept renderings played a key role in the product’s branding and launch. ## Prototyping and Production After testing approximately 40 prototypes, Brown finalized Poka Snack’s design. He is now collaborating with a U.S. manufacturer to produce the skewers while finalizing packaging. The product’s unique geometry ensures ease of use and durability, addressing common issues with frozen fruit products. ## The Adrenaline of Starting Over Brown compares launching Poka Snack to being in college again, fueled by the adrenaline of starting something new. He emphasizes the importance of stepping outside one’s comfort zone and pursuing passions, regardless of age or career stage. ## A Lesson in Career Fulfillment Brown’s career exemplifies the importance of pursuing what excites you rather than following a predefined path. He advises others to focus on their genuine interests and embrace continuous learning, proving that reinvention is possible at any age. ## Sources covering this story - https://fortune.com/2026/09/20/retired-professor-radiologist-richard-brown-turning-to-entreprenuership-career-success-starting-over-poka-snack/ — --- _Summary written by Brifing from the original reporting.
