Clement Cazalot, CEO Doctrakr

I had the luck to be coached by John Lewis.  He always gave us straight answers after careful thought.  I was able to ask a range of questions from problems we had to how we could move faster.  His coaching had a very positive impact as his guidance enabled  us to get our first client, SNCF, and quickly raise our first round of funding.

Building a business requires both an ability to supervise and attention to details. And for many aspects, experience counts.  As an advisor, John brought his unique experience and played a key role in providing us with actionable recommendations that pushed us to the next level

Joan Burkovic, Co-Founder Bankeen

From the start, John Lewis imbued us with the vision to think big and global.  He transmitted the DNA of an American entrepreneur.  John coached and guided us in the strategic decisions of our startup and is still helping us in each stage of our development.  Thanks John.

John has been a real mentor for me. He was the one I would talk to about anything and have the best advice. His main competences: push you to see big, help you define the business model and calm you when you are the most stressed.
