Goblins is revolutionizing education by providing AI-driven one-on-one support in classrooms. Students can draw math on any device, and the AI provides instant feedback to build conceptual foundations. Goblins launched a private beta in March with 15 schools and 300 students, and now has a waitlist of 2,300 teachers, with paid school and district customers across the US and Mexico. The company has raised funds from angels and received a grant from the Gates Foundation.
