We didn't want to invest too much in infrastructure. We didn't want to maintain large server rooms, so we focused on developing our solutions to grow the business. In Poland alone, there are about five million students. However, we aim to transform education all around the globe, so the load can jump from hundreds to several million literally in minutes. How to handle that tide and a fluctuating number of users?

Solwit has extensive experience working with the world's biggest companies. In essence, I don't know how it works, but it does. Therefore, not having to worry about all that tech stuff is a huge comfort for me as a CEO. It is crucial to have someone in business that you can rely on 24/7.
