About Jonas

After two initial experiences in corporate finance - first in investment banking at Natixis Partners, then within the private equity fund Sagard Newgen, specializing in tech and health - I moved into strategy consulting. I joined CMI Stratégies, a firm specializing in strategic due diligence for private equity funds. There, I completed over 20 due diligence missions before venturing into entrepreneurship.

I founded Kinkai, a marketplace dedicated to the pop culture universe, which reached 20,000 users almost organically. In this context, I developed a wide range of skills and managed product, commercial strategy, operations, and finance.

Furthermore, I designed and tested my own method for sourcing experts, both during my consulting assignments and in the context of my entrepreneurial adventure.

Today, I also offer my services to support consulting firms in their due diligence missions. I also work with consulting firms and investment funds on expert sourcing issues, as well as with startups on product and growth-related topics.
