đź‘‹ Hello there!
I’m Justin Shelby. While no one can truly claim to be a “leader” in all of product marketing, I’ve spent 12+ years mastering my craft in hyper-growth AdTech, SaaS, and AI-led environments. As a tech geek with a deep passion for marketing, I’ve always approached it like a game, constantly striving for the highest score by refining strategies, driving adoption, and scaling growth with precision and impact.
Through proven GTM frameworks and years of hands-on experience, I help businesses tackle product marketing challenges with clarity and confidence. Whether it’s launching a new product, refining your positioning, or aligning teams and messaging for long-term success, I’ll bring the tools and expertise to help you win.
And if you’re just looking to chat, brainstorm ideas, or even discuss your career path, I’m here for that too. I’ve helped dozens of individuals kickstart their careers in product marketing, and I’d love to help you level up.
