The Problem
8.2 hrs
per week spent on marking alone
DfE Workload Survey 2025

of teachers have considered leaving due to marking workload

“Marking takes so much time. I’d rather spend that time planning personalised, fun lessons instead of just functional ones.”
Secondary School Teacher
Why Now
Government investment, teacher AI adoption, and an efficacy reckoning are converging to create the biggest opportunity in UK EdTech.
60%
teacher AI adoption
60% of UK teachers already use AI tools, up from 25% in 2023. But they rate generic tools at only 40% classroom-ready. The market needs purpose-built solutions.
£1M
DfE AI investment
The Department for Education announced £1M investment in AI tool development and expanded EdTech trials at BETT 2026. Government policy is actively backing AI in schools.
10%+
minimum learning lift expected
Investors and schools are shifting from growth-at-all-costs to proof of learning impact. EdTech tools must now demonstrate measurable outcomes to survive.
93
contracts expiring
93 EdTech contracts worth £70M are expiring within the next two years across UK schools and MATs. Incumbents are raising prices, creating an opening for alternatives.

“The post-quiz answer grids are brilliant. Being able to see % correct per question means I can spot gaps instantly.”
