Brennan Dunn is a serial founder and product-minded software engineer with 18 years building web and SaaS businesses, from a Norfolk-based agency he scaled and exited to bootstrapping multiple successful products. He founded Planscope and RightMessage—bringing accessible automated segmentation and website personalization to market—and built Double Your Freelancing into a 50,000-strong community before hiring out its CEO. Hands-on technically, he contributed to open-source Rails tooling (improving Geokit’s test suite and multi-database support) and has a track record of shipping backend-heavy SaaS systems. Based in the UK, Brennan blends operator-level strategy with day-to-day engineering and an eye for products that help freelancers and agencies work smarter. His first book, This Is Personal, signals a move to codify his lessons on product, positioning, and customer-driven growth.
