About
I am Nicolas, passionate about investment and wealth management.
I am the co-founder of Prosper Conseil, a leading independent wealth management consultancy firm with more than 1,200 clients, 34 employees and 20% of our expatriate/non-tax resident clients. We work 100% video, so our clients can be anywhere in the world and mobile.
I first had a military career (captain in charge of budget) with expatriation in Ivory Coast.
Passionate about investment since 2009, I ended up leaving the army. With Ludovic Chaput, I created the Avenue des investors site in 2018, which has become a reference in France and French-speaking countries (150,000 monthly visitors). We share everything on Avenue des Investor (ADI) to enable everyone to make the right financial decisions in their lives.
Then in 2022, we created Prosper Conseil, to provide personalized advice via video. Since then, the team has grown to include 34 employees. Always with the same DNA: pedagogy and objective advice. Prosper Conseil is also one of the rare 100% independent firms: our advice is independent, meaning that we are paid only by our clients (annual mission letter) and not by partners (we do not receive any retrocommission from partners so our advice is not biased).
Our advice is 360 degrees: investments and advice on financial and real estate investment, tax optimization of income and assets, retirement preparation and early retirement strategy, advice to entrepreneurs and liberal professions, Luxembourg life insurance, Lombard credit, etc. We are at ease with the problems and challenges of expatriates and non-residents (situation of 20% of our clients).
Contact Prosper Conseil, we will be delighted to discuss your projects.
