In this episode of Chalk and Code, host Theron Davis sits down with Dr. Johannes Ziegler, CEO of Miaplaza, the company behind Miacademy, MiaPrep, and their accredited online high school.
Johannes shares how a small social networking project evolved into a full learner-centered ecosystem for homeschoolers and online high school students. What began as kids’ “edutainment” grew into a mastery-based K–12 model built around motivation, pacing, safety, and authentic engagement.
He also reflects on the entrepreneurial side of building Miaplaza, the role of the right team, and how AI and automation are reshaping the skills students will need next.
