About the job
At Ello, our mission is both clear and vital: to maximize the potential of every child, everywhere.
We are developing the world's first AI teacher, designed to bridge educational gaps by listening, responding, adapting, and inspiring just like the finest human educators.
Our inaugural product, Read with Ello, is already enabling tens of thousands of children each week to enhance their reading skills. It listens to them read aloud, provides assistance when they encounter difficulties, and crafts enchanting, personalized stories using generative AI. It works—and children adore it.
We are now expanding this success into a more comprehensive offering: a fully functioning AI teacher for all children. Our goal is to create a real-time learning platform that integrates language, speech, and memory to deliver personalized, interactive education to kids around the globe. We operate at an impressive pace: deploying updates weekly, engaging directly with children and families for testing, and pushing the limits of AI in education.
Supported by some of the world's leading investors and driven by the heart of a public benefit corporation, we are dedicated to transforming the global education landscape. Recognized in TIME’s Best Inventions and Fortune’s Change the World, Ello is a small, mission-focused team tackling one of the most significant challenges of our time: democratizing education.
