Sean Johnson is an experienced CTO and technical co-founder who has led development at six tech startups over his career. He was the technical co-founder of Hexawise, where he and his team turned an idea sketched on a napkin into a working SaaS prototype in one week and attracted their first corporate client.
In his work, Sean focuses not so much on writing code but on engineering thinking and the quality of decision-making: understanding product goals, testing assumptions, managing uncertainty, and continuously educating the team.
In his materials, he teaches how to use AI consciously—not as magic or as a way to bypass difficult development stages, but as a tool for making better decisions and creating truly useful software.
