Startup Story

Born Out of Necessity

The idea for Blabu came in 2015 when Petr was looking for a native speaker to refresh his German. He found that using traditional language schools or private tutors were not convenient nor flexible options.

The second time the idea occurred to him was in 2017 while being CEO of Skrz.cz. He wanted his team leaders to improve their English as Skrz.cz became part of Secret Escapes, an UK company. The same story - there wasn’t a flexible online tool to meet his requirements. In the end, Petr asked his Canadian friend Jodi to have online lessons with his team 3 to 4 times a week for 15 to 30 minutes. The lessons happened online, via video calls, and the team’s improvement after 2 months was incredible. Petr realised what a fast, easy and effective tool online conversations can be!

 

Technology & Architecture

We are building highly available and scalable platform written in Node.js and run in kubernetes in AWS and Google Cloud with the frontend written in React.js/Next.js. After the MVP, we will begin working on the mobile application in a form of a progressive web app. For client-server API, we use GraphQL and our platform uses microservice oriented architecture. Backend is built on top of PostgreSQL/Redis databases.

The most complicated and demanding technical piece is an integrated solution for  real-time video call streaming with recording ability integrated within the platform. For MVP, we will either choose to use a third-party solution or develop an internal solution, as it’s a key component of the Blabu platform.
