About maxime

After several years in CTO positions, I have acquired solid experience in entrepreneurship, innovation, management, and product development, while continuing to refine my technical skills.

I have served as CTO in startups like Frizbiz and EcoTa.co (which I co-founded), as well as in service companies such as theTribe and Ippon.

- I participated in the development of the Ippon Lille agency (ESN) and the Lille chapter of theTribe (a product/tech studio) as CTO.

- I joined Frizbiz 6 years after its launch, when the CTO position was created. I came on board for the design of a new product on the B2B and B2C model for partners, with the dual objective of a technical overhaul of the existing system.

- I also co-founded a startup, EcoTa.co, where I was CTO. It focused on innovation in the mobility and transport sector. This venture lasted 5 years and allowed me to focus on the overall product design, business model, strategy, client and partner needs, management...

Skills and experience that I would like to leverage in my future assignments.

In my free time (if any)? I love music and play the piano, I go climbing with a strong preference for bouldering, slacklining, sailing...

Always eager for new encounters, exchanges, and advice, feel free to contact me!
