About us

Perpetual Next is powered by an international team of extremely driven professionals. Being it C-level or researcher, we have a few things in common: we are highly experienced, entrepreneurial in nature and devoted to making a change.

Each and every one of us has made it his or her mission to solve fossil-resource reliance and a culture of depletion and waste – by transforming these into renewable and valuable cycles.

Our future is Perpetual.
