In this episode of the EdTech Startup Podcast, host Jeff Bradbury interviews Mike Cronley, co-founder and CEO of Class Composer and former third-grade teacher. Mike shares his journey from the classroom to entrepreneurship, sparked by a casual conversation with his school's music teacher about students being incorrectly placed together. This "aha moment" led him to develop Class Composer, a software solution that helps elementary schools create balanced, equitable classroom rosters. Over seven years, Mike transitioned from teaching while developing his idea as a side project to fully committing to his startup. The conversation explores the challenges of the traditional paper-based class placement process, the importance of listening to customers, and advice for educators considering entrepreneurship.
