Mounir Laggoune is best known for his YouTube videos on investment and for founding Finary, a wealth management app. When you type his name into a search engine, questions about his fortune often arise. However, estimating the wealth of a founder of an unlisted startup is much more complex than it seems.
Wealth in unlisted shares: why Mounir Laggoune’s fortune remains theoretical
Have you ever noticed that wealth rankings assign specific amounts to startup founders? These figures are based on a simple calculation: the percentage of shares owned multiplied by the company’s valuation during the last funding round. The result gives an impressive but misleading amount.
Let’s take a concrete example. Imagine a founder owns a significant share of a company valued at several tens of millions of euros. On paper, his fortune seems substantial. In practice, these shares cannot be freely sold on a market. There is no stock exchange for shares of private startups.
This is exactly the situation of Mounir Laggoune. The bulk of his wealth consists of unlisted shares of Finary. Several recently published financial analyses highlight that the liquid portion of his wealth remains unknown due to a lack of detailed public disclosure. By consulting Mounir Laggoune’s fortune on Libre Finance, one can see this distinction between theoretical value and actually available wealth.
This nuance is fundamental. A wealth primarily composed of unlisted securities can vary from simple to triple depending on market conditions, shareholder agreement clauses, or the possibility of selling during a secondary funding round.
Finary’s Series B funding: what 25 million euros really changes
In September 2025, Finary announced a Series B funding round of 25 million euros. The investors involved are not insignificant: PayPal Ventures, Hedosophia, Y Combinator, and Speedinvest participated in this round.
Why does this funding matter so much? Because it sets a new price for Finary’s shares. Each funding round re-evaluates the company, and this re-evaluation mechanically changes the theoretical value of the founder’s shares.
How a post-funding valuation works
When an investor injects millions into a startup, they buy a percentage of the company at a given price. This price serves as a reference to estimate the total value. If a fund buys 10% for 25 million, the company is theoretically valued at 250 million.
This calculation does not reflect what a real sale of the entire company would yield. Investors often benefit from liquidation preference clauses, which guarantee them priority repayment in case of resale. The founder, on the other hand, comes after.
In practical terms, the Series B increases the paper value of Mounir Laggoune’s shares. But it does not put a single cent more in his bank account, unless he sold part of his shares during this round (which has not been made public).
Finary and YouTube revenues: the real flows behind the wealth
To understand the real fortune of an entrepreneur, one must distinguish two things: the value of their shares (theoretical) and their current income (tangible). Mounir Laggoune has several identifiable sources of income.
- Income related to Finary as a manager: salary and possible bonuses, the amount of which is not public but exists like for any funded startup CEO
- Advertising revenue and partnerships from his YouTube channel, which attracts a broad audience in the personal finance niche
- The growth of Finary itself, which has over 500,000 users and whose model relies on a premium subscription generating recurring revenue
The ARR (annual recurring revenue) of Finary is a key indicator for estimating the economic strength of the company. A startup with rapidly growing ARR and renowned investors is more likely to see its valuation confirmed during a potential acquisition or IPO.
The trap of estimating by YouTube revenue
Some sites estimate the wealth of content creators solely based on their YouTube views. This calculation is very approximate. CPM (cost per thousand impressions) varies greatly depending on the theme and seasonality.
In the case of Mounir Laggoune, YouTube is an acquisition channel for Finary, not its main source of revenue. The goal of his videos is to attract users to the app. Reducing his fortune to his YouTube earnings would be like evaluating a restaurateur solely on their tips.
Finary SAS in the commercial register: what public data shows
A often overlooked source for estimating a company’s financial health is the accounts filed with the registry. Finary is registered under the SIREN number 892357724. The annual accounts filed allow for consultation of revenue, losses or profits, and share capital.
- The SAS (simplified joint-stock company) status is the standard choice for French startups funded by venture capital
- The filed accounts do not directly reveal the personal wealth of the founder but provide clues about the company’s profitability
- The capital structure after several funding rounds shows how much the founders have been diluted, meaning what share of the company they still own
Dilution is the most underestimated factor in evaluating founders’ fortunes. After a Series A and then a Series B, a founder may own only a fraction of the company they created. Without knowing this exact percentage, any estimate remains speculative.
The public data available on societe.com confirms the existence and activity of the structure but does not allow for a precise determination of personal wealth. Anyone announcing an exact figure for Mounir Laggoune’s fortune is making an extrapolation, not a statement of fact.
