Who's watching
A primarily male, working-age technology audience, with the U.S. as the largest market. Viewers come for straight talk on software development, AI, developer careers, technology, entrepreneurship and practical business/life advice.
Why brands partner with Stefan
- Earned credibility – building for the web since 1994 and teaching code since 2003. When Stefan recommends something, it comes from three decades of hands-on experience, not hype.
- An audience that builds things – developers, aspiring developers and tech entrepreneurs who evaluate and buy tools, courses and services.
- Educator first – founder of StudioWeb (used in schools across North America), long-time publisher of Killersites.com, and author of Web Design – Start Here.
- Trusted by tech brands – past collaborations include PayPal, Docker, JetBrains, Replit, Wix, BenQ, Lovable and Viktor.
- Long-form + short-form – in-depth YouTube videos backed by TikTok and Instagram reach.
Uncle Stef's Developers Bootcamp
Stefan also runs Uncle Stef's Developers Bootcamp at unclestef.com, a mentoring program with bi-weekly live coaching, a private developer club and one-on-one Elite Mentoring. Partners get more than views: they reach an engaged community of developers who are actively investing in their skills and careers.
