About the job
At Ello, our mission is both compelling and urgent: to maximize the potential of every child, everywhere.
We are pioneering the world’s first AI teacher, designed to bridge educational gaps by listening, speaking, adapting, and inspiring in the same way that exceptional human educators do.
Our inaugural product, Read with Ello, is already making a significant impact, helping tens of thousands of children each week to learn to read. It listens attentively as they read aloud, provides assistance when they encounter challenges, and crafts personalized, enchanting stories through generative AI. The results speak for themselves—children love it!
We are now scaling our success to create something even more transformative: a comprehensive AI teacher for all children. Our goal is to develop a real-time learning platform that integrates language, speech, and memory, delivering personalized, interactive education to children across the globe. We are a fast-paced team, shipping weekly, testing directly with children and families, and continuously pushing the boundaries of AI in education.
With the backing of top-tier investors and the heart of a public benefit corporation, we are on a mission to revolutionize global education. Featured in TIME’s Best Inventions and Fortune’s Change the World, Ello is a small, mission-driven team committed to addressing one of the most critical challenges of our time: democratizing education.
