Nell & Key is a children’s learning brand that helps students discover mathematics through the subjects and activities they already love. Designed for children roughly aged seven to thirteen, its personalized approach connects maths with interests such as drawing, skateboarding, Spanish, circuits and website building. Each child receives an individual mission, adapted to their interests and grade level, so learning feels relevant rather than one-size-fits-all.

The Nell & Key membership includes one-to-one tutoring, daily stories that develop critical thinking, problem-solving and decision-making, and a personal book documenting how a child sees the world. Families can follow progress through regular tutor updates and a growing record of the child’s work. Missions are supervised, and parents receive updates; sessions are scheduled with the family before payment. Enrollment begins with an introductory conversation with the founder to discuss the child’s needs and goals. The service requires an iPad or Mac, and children retain ownership of what they create.
