MagicSchool is used by 6 million educators and counting — including at least one in every school in America — after just 2 years. Adeel Khan is one of the most inspiring and mission-oriented founders I know. Former teacher and Principal, he’s now focused on giving educators and their students the tools they need to be successful. My work with Adeel and other solo founders inspired the Solo Founders Program.
