We are Blue21, starting a Blue Revolution

How? By realizing floating cities with a positive impact on the planet. Because we believe that this way we can solve the biggest challenges of the 21st century: land scarcity, climate change, urban growth, and deforestation.
 
Why?

 

We know it’s possible

But we can’t do this alone. That’s why we are a social enterprise and collaboration platform.
 
About us

ready to make waves?

Together we can start the Blue Revolution of the 21st century.
