Welcome 2023


2022 – The world is going back into recession, inflation is looming, interest rates are going up, “Nothing new under the sun, welcome back to the 70s !” one would say… I beg to defer.

The last fifty years have seen unprecedented, extraordinary changes in our world. The world population doubled while the post-second war world order was breaking down. We witnessed two financial and two natural resources crisis. We barely avoided two social revolutions and are now experiencing a full-blown war on the old continent.

Most noticeably, the digital revolution happened. It transformed the way we work, we learn, we communicate, we consume. It accelerated the pace for economy, competition, life even. In the process, we re-assessed our morals, ways of thinking and behaving. We entered a frenetic race for the “more”, the “fast” and the “easy” in every area of wealth and…life. Consequently, we created a new paradigm, and simply forgot we are dwellers of one fragile and limited planet. As evolved as we, Sapiens, are, still, we are merely part of an infinite whole in a finite environment.

The recent pandemic, tsunamis, heat or cold waves are subtle nudges that something is looming and needs to be addressed, before we truly are on the brink of collapse. A call for change, a call for transition.

Accept the past, protect the future.

It is time to innovate, serve and cater for energetic, food, health and social needs in ways that would ensure a sustainable future for humanity…and the world of finance must take a leading role in this transition process ! But not just any type of finance. A new breed of Venture-Capitalists free from hyper-growth and unrealistic return on investments mindset. The #humanistVC interested in re-kindling the raison d’être of finance: long term value creation geared towards building a prosperous economy, where people matter.

Let’s wish for 2023 to see the emergence of a thriving and….fairer society, even if money does make the world go round!
