About us

Who we are

CBproject was founded in September 2021, when two first-year students of a technical high school in Katowice joined the "Mini-enterprise for Teens" programme. Instead of opening a small online shop like most participants, they set out to build a real invention — a bottle able to both cool and heat liquids, later named CBkelvin. What started as a school project quickly grew into a team of young inventors turning ideas into working products.

Awards & recognition

Our work has been recognised at some of Europe's most prestigious invention fairs. CBkelvin won silver medals at both Concours Lépine 2023 in Paris and INTARG 2023 in Katowice, which also led to a feature on TVP3 Katowice television.

In 2026 our project ThU reached its MVP and was awarded a gold medal at INTARG 2026, together with the prestigious WIPO Award for innovation. Earlier inventions such as the CBmahlo eco-heater brought further successes, including a place in the e(x)plory finals and the main prize of the "Youth of the Future" contest.

Where we're heading

We are not ones to rest on past results. Our team keeps developing new projects — from software to everyday physical products — driven by the same curiosity that started it all. We won't stop until every one of our ideas becomes reality. Follow us to see what we build next.

Our history:

September 2021
The creation of CBproject

Two students of the Technical High School of Aviation in Katowice are taking part in the contest. The inventors' group is created as the result.

October 2021
CBkelvin prototyping

The first prototype of the CBkelvin bottle gets created.

May 2023
Debut of CBkelvin during the major European fairs

Two fairs, one in Paris and one in Katowice, made it possible for the inventors to introduce their solution to the public. Both fairs resulted in getting a silver medal. 

June 2023
CBmahlo: the ECO-heater

During the summer holidays, the heat exchange in thermoelectrical elements pushed the inventors to create a heater of compact size and low energy consumption.

October 2023
First TV interview

After winning the medals and refining CBkelvin, the inventors are invited to the TVP3 Katowice TV station.

May 2026
Gold & WIPO Award for ThU

Project ThU reaches its MVP and wins a gold medal at INTARG 2026 in Katowice, along with the prestigious WIPO Award for innovation.
