Junior Einstein

Junior Einstein is an educational publisher focused on primary-school children. They run an online platform where kids can practise across multiple subjects, and they publish physical workbooks alongside it. More than 100,000 children use Junior Einstein's exercises every week.

Digital challenge

Modernise the frontend stack of a platform that thousands of children rely on every day, without slowing down the in-house team.

We started working with Junior Einstein in September 2025. Since then we've helped with:

• Modernising the frontend stack
• Setting up AI-assisted workflows to improve developer experience — Junior Einstein leans in hard on AI within development, which made this as much an experiment as a delivery
• Building a reusable component library that gives a uniform look and feel across their many applications
• Coaching and standing in as fallback capacity for the in-house development team
