By combining the latest in AI and eye-tracking technology, our unique, paperless assessment can offer an entirely new insight into literacy, analysing a child’s skills across key reading components, determining their attainment, and highlighting potential difficulties in a matter of minutes. With immediate, fully objective and in-depth results, teachers can then work with our dedicated intervention package to support both emerging and fluent readers in their development. Following 30 years of academic research at the Karolinska Institute, which has selected the Nobel laureates in Physiology and Medicine since 1901, we first launched our unique method of measuring reading attainment in Sweden in 2015. After a successful entrance into the US in 2017, we then launched in the UK early in 2018. Our work across the globe is still driven by the same overarching commitment to education and literacy upon which Lexplore was founded many years ago. Literacy skills are fundamental to so much of school life and beyond, yet in the UK almost 148,000 children still leave primary school unable to read well. Our mission from the start was to provide teachers with the technology, resources and information needed to identify those struggling readers early and raise attainment for all pupils. Since 2015, our assessment has undergone much further development. Today, having conducted more than 200,000 tests across the UK, US, Sweden and internationally, we have featured heavily in the press, including on BBC News, been nominated for BETT, E-Assessment and ERA awards, and have been ranked 8th in Europe’s top 50 most innovative companies! We are also extremely proud that our assessment and interventions are helping to the bridge the literacy gap globally! Our partners at the LING Project are currently travelling Northern Ghana using our technology to raise reading attainment amongst the female population.

Energy leaders are ready to deliver flexibility, but outdated systems and a complex market slow progress. Fever removes those barriers. Its unified platform connects, qualifies, optimises, and monetises assets in real time—unlocking quick wins that are reliable, compliant, and scalable. The outcome: services customers trust and adopt, new recurring revenues, and a stronger position as a modern, resilient utility. As competitors move quickly, reputation and revenues are at risk. Fever helps utilities step confidently ahead—accelerating their role in the energy transition.
