Themis is one of the smartest and more capable people I know.
Themis has amazing credentials combined with an entrepreneurial spirit - she went to two of the top engineering schools in Brazil, got her MBA at Insead, started and ran several companies as an entrepreneur. She is also a mother of two children. No small feat.
She is a master at execution - has the "engineering level" capacity to organize matters, share her vision with her staff, investors and people around her and to get things done. She is very strategic in the path she wants to take in the companies she runs. All of this with tremendous energy, calmness and understanding of the forces that drive each and everyone around her.
She has great confidence in her ability to think through situations but is humble enough to seek guidance when needed.
I cannot recommend anyone more highly than Themis - one of these rare combinations of entrepreneurial spirit with adult strategic thinking and mastery at execution.
