IES alumnus, Guillaume Labbez founded CommStrat in 2017 with a clear conviction: leaders don’t need spin — they need strategy.
CommStrat is an independent consultancy in communications, public affairs, and executive advisory, working with business leaders and companies facing complex decisions.
We operate where clarity of thought, precision of message, and the ability to influence make the difference between reacting and leading.
Guillaume holds a Master’s degree in Constitutional Law and Civil Liberties (Panthéon-Sorbonne) and an Executive Master from Sciences Po Paris.
Affiliate Professor, he teaches Negotiation, Strategy, and Influence at the Sciences Po School of Public Affairs and at Sciences Po School of Public Affairs and Sciences Po Executive Education.
A former advisor to ministers, prime ministers, and presidential candidates, he now supports decision-makers who choose to lead with purpose and reason.
