Investor Serhii Tokarev: EdEra and the Tokarev Foundation have launched BigMat, a maths platform for school pupils

EdEra, an online learning studio, with the support of the Tokarev Foundation, launched the free digital product BigMat. This online product provides simple answers to complex mathematical problems and engages children in practical and interactive exercises and real-life examples as they study the topics. Serhii Tokarev, an investor, IT entrepreneur and founder of the Tokarev Foundation, shared details of a project for schoolchildren, teachers and parents.
Why the BigMat platform is essential today
The outcomes of the 2025 National Multi-Subject Test revealed that 12% of graduates failed the mathematics part of the test. To determine the reasons for learning losses, the online education studio EdEra, together with the Tokarev Foundation, conducted research. It found that most knowledge gaps appear to occur in secondary school.
EdEra also drew attention to the phenomenon of maths anxiety — a state in which a pupil develops a fear of the subject that hinders their learning. The digital product was developed specifically to overcome these obstacles.
“One of the key prerequisites for accessing the modern tech economy is mathematical literacy. If we do not solve this problem today, we will face a shortage of specialists in engineering, product development and AI technologies as early as tomorrow. This will inevitably affect the ability of Ukraine’s next generation to compete in the global market,” says Serhii Tokarev.
How the BigMat platform works
The BigMat digital product takes the form of an app featuring interactive levels for pupils, guidance for parents and ready-to-use teaching resources for teachers. Abstract and complex maths topics are explained using examples from everyday life — calculating costs, making everyday decisions, and so on. The main idea is to bridge the gap between pupils who find maths easy and those for whom the subject is a real hurdle.
“Together with the Tokarev Foundation, we have developed a maths platform that will help pupils understand complex topics through real-life examples. The app is currently at the MVP stage. Launching the pilot will allow us to test it with students, teachers and parents,” says Illia Filipov, CEO of EdEra.
What stage is BigMat at right now?
The team has prepared eight lessons, materials for eight topics on fractions and created eight interactive levels. The product is already being tested by 60 teachers with their classes. In total, more than 500 teachers have applied.
In the second stage, which will begin in the autumn, revisions will be made and the list of topics expanded. Additionally, guidance is being prepared for parents so that they can help their children without needing to hire tutors.
