Nataliya Limonova

Founder at Global Innovative Online School (GIOS)

We partnered with OneSource to build our platform. Their design was intuitive and in just a week, they showed us an MVP. They built a tool that truly meets our needs. Even if our students miss an event, they can watch videos later and get graded automatically. Since the platform's launch, we have seen a 35% increase in event participation and a 50% rise in the number of video lectures accessed by our students.

OneSource understood us perfectly. Thanks to them, over 1000 of our executors now benefit from this platform.
