About us
We are a clean tech startup based in Amsterdam and Barcelona. We provide software solutions and advisory services to help companies achieve zero-carbon energy goals.

We are working to make 24/7 carbon-free energy procurement a widely adopted market practice among buyers in order to push for true, full decarbonization of the electrical grid.

This vision also includes 24/7 procurement certification, as well as the development of simpler solutions that any corporate buyer can use today to get started on the 24/7 journey without disrupting their existing sustainability agendas, which are frequently based on so-called "volumetric energy goals" ( percent renewables).

FlexiDAO is a founding partner of EnergyTag, to promote and build an energy market where energy users verify the source of their electricity and carbon emissions on an hourly basis.

We are supported by SET Ventures, a venture capital firm focused on innovative energy cleantech and accelerators like InnoEnergy and Rockstart.

We are also affiliate members of the Energy Web Foundation and are proud to be financed with EU funds by CDTI in the Beyond project in which we participate.


We are looking forward to hearing from you!
