## About i-potentials

VC Fund · Berlin, Germany

i-potentials emerged from the nucleus of the German digital economy in 2009 – started out of an observation: a new form of recruitment consulting was needed for this new branch of industry. A consultancy that understood positions in innovative business models. A consultancy that could keep up with the dynamics of fast-growing organizations. Thathas been our mission ever since. We are driven by the ambition to shape tomorrow’s economy with our executive placements, and by the passion to bring people together who move the world forward. And as an executive search firm – just like any other company – we can only succeed at that as a team.
