Henri Seydoux Net Worth: How to Estimate and Verify It

Henri Seydoux's net worth as of April 2026 is best estimated in the range of 150 to 300 million euros, with the figure driven almost entirely by his controlling stake in Parrot SA, the French drone and wireless technology company he co-founded in 1994 and has led as Chairman and CEO ever since. That range isn't a guess pulled from thin air, it's a function of Parrot's market capitalization on Euronext Paris, Seydoux's disclosed ownership percentage through his holding vehicle Horizon SAS, and a set of reasonable assumptions about private assets and compensation. Here's exactly how to verify that estimate today, why different sites publish different numbers, and what to watch for when you check back later.

Who Henri Seydoux is and why people search his wealth

Henri Seydoux is a French entrepreneur best known as the founder of Parrot, a Paris-based technology company originally focused on wireless accessories and consumer electronics before pivoting heavily into professional and commercial drones. He co-founded Parrot in 1994 and has served continuously as its Chairman and CEO. Parrot was once a consumer darling, its AR.Drone quadcopter became one of the first mass-market consumer drones, but the company has since repositioned itself as a defense and professional-use drone manufacturer, a strategic shift that has significantly affected its valuation and, by extension, Seydoux's net worth.

People search for his net worth for a few distinct reasons. Business journalists and analysts tracking the French tech sector want a ballpark on key founder-shareholders. Investors or competitors researching Parrot's ownership structure end up on his profile. And frankly, a fair number of searches come from people who confuse him with other prominent French figures sharing similar surnames or first names, the French business world has several high-profile Henris, including Henri de Castries (former AXA chief) and Henri Giscard d'Estaing (Club Med). Some readers also search for Henri de Castries net worth, which is a different profile tied to a career in finance rather than Parrot. Seydoux is also a prominent French family name in media and film (the Seydoux-Pathé family), so disambiguation matters here: this article is specifically about Henri Seydoux the Parrot founder and tech entrepreneur. Many readers also search specifically for Henry Loubet net worth to compare how different wealth profiles are estimated.

What 'net worth' actually means, and why estimates vary

Net worth is total assets minus total liabilities. For a private individual, that includes the value of any business stakes, real estate, investment portfolios, cash, vehicles, art, and other holdings, minus debts like mortgages or business loans. Simple in theory, almost impossible to pin down precisely for someone who isn't required to publicly disclose their personal balance sheet.

The reason you see wildly different figures across wealth-tracking sites comes down to a few core problems. First, private assets are invisible unless someone discloses them. Second, even publicly traded stakes fluctuate daily with share prices. Third, different sites use different methodologies, some count gross equity value (the stake before any debt), some try to net out liabilities, and some just pull a number from another site that cited yet another site, creating a telephone-game problem with no original sourcing. For someone like Seydoux, whose primary identifiable asset is a controlling stake in a mid-cap publicly traded company, the estimate is more grounded than for a purely private operator, but it still carries meaningful uncertainty.

How to estimate his net worth: the methodology step by step

The most defensible approach starts with what's publicly disclosed and works outward from there. Here's the actual workflow to follow if you want to verify the estimate yourself today.

1. Look up Parrot SA's current market capitalization on Euronext Paris (ticker: PARRO). This is the public market's live valuation of the entire company.
2. Find Seydoux's disclosed ownership percentage. Parrot's Universal Registration Document (URD/Document de Référence), filed annually with the AMF (Autorité des marchés financiers), includes a shareholding table. Horizon SAS is the disclosed holding vehicle owned by Henri Seydoux — check the most recent filing for the exact percentage.
3. Multiply his ownership stake by the market cap to get his gross equity value in Parrot.
4. Apply a control premium or holding company discount where appropriate. Controlling shareholders can command a premium in a buyout scenario, but holding company structures often trade at a discount to NAV in practice. Analysts typically use a 10 to 25 percent discount for such structures.
5. Add reasonable estimates for private assets: executive compensation (salary plus bonuses disclosed in Parrot's governance report), dividends received from Horizon SAS, real estate, and other investment holdings — none of which are publicly verifiable but can be roughly modeled from disclosed compensation.
6. Cross-check against credible French financial press (Les Echos, Le Figaro Economie, Capital magazine) and any transaction filings on the AMF site that show share purchases or sales.

The AMF filings are particularly useful because French securities law requires disclosure of significant share transactions by major shareholders. Parrot's own corporate governance report for 2017 already showed this in practice: it documented that Horizon SAS acquired 283,000 Parrot shares on August 1, 2017, and a further 17,000 shares on August 2, 2017, with prices and AMF references cited. That kind of disclosure trail is exactly what gives you a verifiable paper record of ownership changes over time.

The net worth range and what's driving it

Pulling this together for April 2026: Parrot has undergone significant transformation since its consumer drone days. The company shed its consumer division and focused on professional and defense drones, a transition that compressed its market cap substantially from its peak years but has since given it a more defensible position in a growing sector, especially given European defense spending trends in 2025 and 2026. Based on Parrot's publicly traded valuation and Seydoux's disclosed controlling stake through Horizon SAS (historically above 50 percent of shares and voting rights), his gross equity value in Parrot alone is the anchor of any estimate.

Putting it together: a conservative base estimate anchored to Parrot's market cap and Seydoux's controlling stake, with a holding company discount applied, lands in the 100 to 200 million euro range for the Parrot stake alone. Adding probable private assets and accumulated compensation over a 30-year career as founder-CEO moves the total estimate to the 150 to 300 million euro range. The wide spread reflects genuine uncertainty about private holdings, not sloppiness in the methodology. Anyone quoting a precise single figure for a private individual's net worth is offering false precision.

Public holdings, filings, and income indicators to check

If you want to do this research yourself, these are the specific sources to check in priority order.

• Parrot's Universal Registration Document (Document d'Enregistrement Universel) filed with the AMF: this is the single most important document. It contains the shareholding structure table, identifies Horizon SAS and its ownership percentage, and discloses executive compensation packages including salary, bonus, and any stock options or free shares granted to Seydoux.
• AMF transaction disclosure database (declarations-amf.fr): search for 'Horizon SAS' or 'Henri Seydoux' to find any share transactions that have been declared. French law requires major shareholders to disclose purchases and sales above certain thresholds.
• Euronext Paris (euronext.com): check PARRO's live share price and market cap to anchor your equity calculation in real time.
• UK Companies House (companies house.gov.uk): a UK filing shows Seydoux was appointed director of Schlumberger N.V. on January 15, 2014, and resigned on April 6, 2022. This directorship would have carried board fees and is now closed, but it's a useful data point confirming his broader international corporate presence.
• Parrot investor relations page (parrot.com/investor-relations): annual reports, half-year results, and governance documents are hosted here and are the official corporate source.
• French financial press: Les Echos and Capital magazine periodically profile French tech founders and sometimes include wealth estimates or ownership context that can be cross-referenced.

One thing worth noting: Parrot's governance reports explicitly identify Seydoux as having 'controlling influence' over the company through Horizon SAS. That language matters legally and financially, it means he isn't just a large minority shareholder but holds decision-making control, which typically carries a valuation premium if the stake were ever sold.

Why the numbers change over time

If you checked a net worth estimate for Henri Seydoux two or three years ago and the number looks different today, that's not necessarily an error on either end. Several forces move the figure legitimately.

• Parrot's share price: as a publicly traded company, Parrot's market cap fluctuates with every trading session. A 20 percent swing in the stock moves Seydoux's paper wealth by tens of millions of euros.
• Strategic pivots and business results: Parrot's shift from consumer to professional drones compressed its valuation significantly in the 2017 to 2020 period. Subsequent defense contracts and the broader European defense spending surge have been tailwinds. Each quarterly earnings report can materially shift the market cap.
• Disclosed share transactions: if Horizon SAS buys additional shares (as it did in August 2017) or sells shares, Seydoux's ownership percentage and gross value change. These transactions are disclosed on the AMF site.
• Dividend distributions: if Parrot pays a dividend or Horizon SAS distributes capital, Seydoux's liquid wealth increases but his equity stake may decrease — the total net worth picture shifts even if the headline changes.
• New business stakes or divestments: if Seydoux invests in or exits other companies, that changes the private asset side of his balance sheet — though these moves are typically invisible unless disclosed in a governance document or press report.
• Currency and macro effects: Parrot reports in euros, so for anyone tracking in other currencies, exchange rate movements add another layer of variability.

The practical upshot: treat any net worth figure for Henri Seydoux as a snapshot tied to a specific date and market context, not a fixed number. A useful quick check is the article’s roundup of Henri Nestlé net worth to compare how wealth is estimated across different industries. A useful quick check is the article’s roundup of Henri Leconte net worth to compare how wealth is estimated across different industries, even though the drivers of net worth can differ by person. If you want the exact figure people cite most often, the latest reporting tends to summarize &lt;a data-article-id=&quot;2D3B42DA-C4B7-45EB-96B2-F1E68931D0B9&quot;&gt;Henri Seydoux net worth</a> as of 2026. The most current and defensible estimate will always be built from the latest AMF filings plus the current Parrot share price. If you're finding an estimate that hasn't been updated since 2022 or earlier, it almost certainly doesn't reflect Parrot's post-pivot valuation or any transactions since then. Re-running the calculation using the steps above takes about 20 minutes and will give you a more reliable figure than any static webpage.

For context within the broader French business world, Seydoux's estimated range puts him well below the ultra-high-net-worth tier occupied by industrial dynasty figures, but solidly in the territory of successful founder-operators who retain large controlling stakes in mid-cap listed companies. If you're researching other prominent French figures for comparison, the methodologies for estimating wealth are similar across the board: anchor to publicly disclosed equity stakes, layer in disclosed compensation, and flag private assets as structurally unknowable without insider information.
