Polymath: $1 Million Raised To Turn Kid-Focused App Into A Productive Experience

By Amit Chowdhry • Feb 21, 2025

Kid-tech startup Polymath announced it has secured $1 million in funding with notable investment from ClassDojo CTO Liam Don in their first angel round, followed by a venture-backed pre-seed raise co-led by Blackbird Ventures and GD1. This funding accelerates Polymath’s US market expansion, bringing exciting targeted math learning to 23+ million children.

Polymath is a learning game that kids want to play. Despite spending upwards of 4 hours a day on screens outside of school, kids only spend a few minutes minutes on average on educational apps. Instead, they spend time on games, watching videos, and using social media. Polymath aims to change this by merging an adaptive learning algorithm with a sandbox gaming world, keeping thousands of elementary-aged kids engaged for an average of 30 minutes per session. And data shows regular Polymath users learn up to twice as fast as non-users.

Liam Don, the CTO and co-founder of ClassDojo had first invested in Polymath during its angel round. And ClassDojo is an education technology unicorn with over 50 million users, namely teachers and families, whose app bridges the gap between home and school.

Polymath’s founders, Sophie and Christian Silver are obsessed with fighting the drop in math attainment that has been snowballing for the last 20 years. And Sophie’s passion for education started with inventing games for children she worked with while studying human learning at UCL. Christian (a Cambridge Computer Science graduate) helped turn those ideas into a dynamic learning app.

Polymath is used in the household and at schools, with the school version engaging students and serving as a gateway to the at-home experience, proving parents can trust Polymath with genuine educational endorsement.

Polymath is used both at home and in classrooms. And teachers can adopt it for free, making it easy to integrate into lesson plans. U.S. teachers in states like AZ, VA, SF, FL, TX, and CA are already raving about the app.

Kids take Polymath home because they enjoy it. And at home, they gain access to all game features, reinforcing learning through play.

With this funding, Polymath will expand in the U.S. and introduce collaborative play, enhancing the collaborative aspects of learning. Already played by tens of thousands of children worldwide, Polymath continues growing in the U.S., U.K., New Zealand, and Australia.
