Become an Innovation Pavilion Partner

If you are an incubator, university, corporate venture fund, impact fund, accelerator, or SME network, you have the opportunity to become one of our Innovation Pavilion Partners.

The Innovation Pavilion Partners will be given an exhibition space within the Breakthrough Innovation Zone, with enough space for 6-8 ClimateTech Start-Ups in your network. This will provide the opportunity to position your brand as an incubator of new climate solutions and force for change, whilst connecting the start-ups in your network with the stakeholders that can help them reach scale.

If you are interested in becoming one of our Innovation Pavilion Partners, please get in touch with us at [email protected]
