GreenCrowdFunder believes in, stands by and stays with Btsun.

The Fundraising campaign continues but in a different way.

Our platform GreenCrowdFunder has decided to continue supporting BTsun, the dynamic and innovative company that is developing its solar business by capitalizing on the opportunities created by the new Swiss Energy Law.

BTsun is currently reviewing microgrid applications operational in other countries to offer similar solutions very soon in Switzerland. 

We will come back to you to tell you about this quality project and the alternative solutions being put in place to accompany its success. 

See you very soon,

The GreenCrowdFunder team, 

Investing sustainably together


Who we are

GreenCrowdFunder is a crowdfunding platform which supports innovative environmental projects.

In 2016, Pierre Biraben and Alan Tawil-Kummerman, both passionate about entrepreneurship, took up the challenge of alternative economics and created GreenCrowdFunder, a digital platform for CrowdFunding (shares and bonds) to support the development of quality projects in the environmental field. These "senior entrepreneurs" identify “green” projects, help structure them, assess their various risks, and then invite investors to finance them. Veronique Sala joined Pierre and Alan to broaden the scope of GreenCrowdFunder’s communication strategy.
