I am the founder.  Sum was founded out of my own experience as a McKinsey partner and CEO.  It is fair to say that for two decades I operated as an insecure overachiever.  My mid life reflection around the It-We-I triangle showed a dramatic bias towards to the It, strategy, structure, M&A, achievement.  And a lot to explore about myself and the way how I relate to others.  I defined my purpose as ‘helping executive take their heart to work’ and started to create spaces where we can be ourselves, allow vulnerability to connect as a team and jointly address the challenging business topics.  My biggest reward is when I see client teams allow themselves to discuss the difficult questions and use our tools to pursue a compelling aspiration and purpose.  Business as a force for good with sum space inside!
