As of May 2026, Forbes puts Thierry Cruanes' real-time net worth at approximately $1. Thierry d'Ascanio's net worth is often discussed in the same context as high-profile tech founders and equity-driven fortunes thierry d'ascanio net worth. 2 billion, based on a snapshot dated April 16, 2026. That figure comes almost entirely from his founding equity stake in Snowflake, the cloud data platform he co-founded in 2012. It's a number that has moved around a lot since Snowflake's IPO in 2020, and it already dropped low enough in 2025 to push him off the Forbes billionaires list entirely before recovering.
Thierry Cruanes Net Worth: Estimate, Sources, and Method

Who Thierry Cruanes is and why you're searching for him
Thierry Cruanes is a French-born technologist and entrepreneur, currently listed by Forbes as a U.S. citizen aged 58 (born June 1967 per French business registry data). He is best known as one of the three co-founders of Snowflake, the cloud data warehousing company, alongside Benoit Dageville and Marcin Zukowski. The company was founded in 2012, went public in September 2020 in what became one of the largest software IPOs in history, and was valued at $12.4 billion in pre-IPO fundraising rounds before the listing pushed that figure far higher.
Within Snowflake, Cruanes has served as Chief Technology Officer (CTO). His technical focus has been on query optimization and parallel execution, which were core architectural features that differentiated Snowflake in its early years. SEC filings, proxy statements, and the company's own blog all confirm him in that CTO role. His name appears in Snowflake's S-1 prospectus, annual reports, and DEF 14A proxy filings alongside co-founder Benoit Dageville, which is how he first attracted serious net worth tracking.
Because this site covers French wealth and business figures, it's worth clarifying: Cruanes is French by origin, and French business directories including Pappers and Societe.com link him to several property-holding entities in France. But his primary wealth is tied to a U.S.-listed tech company, which makes him a somewhat different profile from luxury or fashion dynasty figures. Still, he is a genuine high-net-worth French national, and his name surfaces in the same searches as other French entrepreneurs and business figures.
Where his money comes from
Cruanes' wealth is almost entirely equity-based. As a Snowflake co-founder, he received a founding stake in the company that was subject to vesting and dilution through multiple fundraising rounds before the IPO. When Snowflake went public in September 2020, co-founders' equity translated directly into public-market wealth. His net worth has tracked Snowflake's stock price ever since.
On top of equity, SEC filings and Snowflake's annual reports confirm that Cruanes received executive compensation in his CTO role, including base salary and performance bonuses tied to company goals. That executive pay is real but relatively small compared to the equity picture. For someone at his level in a company that was valued in the tens of billions at IPO, the meaningful wealth figure is almost always the stock, not the salary.
There is also a French property dimension. Pappers and Societe.com list Cruanes as gérant and associé of several French SCI (société civile immobilière) entities: INOYB1, INOYB2, INOYB3, and TIMALAUNE. SCI structures in France are commonly used to hold real estate, often in a tax-efficient way for individuals with significant assets. INOYB1 was incorporated on September 21, 2021, and is associated with an address in Grasse, a town in the Alpes-Maritimes department known for its proximity to the Côte d'Azur. These entities suggest real estate holdings in France, likely in a high-value area, but no public valuations are available for those properties.
The net worth estimate: numbers, ranges, and how to think about them
Forbes' real-time tracker shows $1.2 billion as of April 16, 2026 (profile updated March 10, 2026). That is the most credible public estimate available. Forbes arrives at figures like this by multiplying known or estimated shareholding percentages by the current market capitalization of the relevant public company, then applying standard discounts for liquidity constraints or pledged shares where known.
The honest range for Cruanes' net worth as of May 2026 is roughly $900 million to $1. For the latest figures and context on Thierry Neuville net worth, check the same Forbes updates used for this estimate Cruanes' net worth. 4 billion, depending on when you check Snowflake's stock price. His wealth dropped below the billion-dollar threshold in 2025, which is why Forbes noted he dropped off the 2025 billionaires list in an article published April 2, 2025. Since then, the stock has recovered enough to bring him back to the $1.2B level. If Snowflake's stock falls 25–30% from current levels, he drops off again. If it rises, the number climbs accordingly.
One important methodological note: Forbes' wealth estimates for tech founders are based on publicly disclosed ownership stakes plus assumptions about unvested equity and any known share sales. SEC Schedule 13G filings confirm that Cruanes has had reportable beneficial ownership of Snowflake shares, and a later filing indicates his ownership fell below the 5% threshold that triggers ongoing Schedule 13G reporting. That's a signal that his direct stake has been diluted or reduced over time, which is typical for co-founders at a company that has grown through many equity rounds and issued stock-based compensation broadly.
What the evidence actually supports
Here is a clear breakdown of what is confirmed versus what is estimated or inferred.
| Claim | Evidence quality | Source type |
|---|---|---|
| Co-founder and CTO of Snowflake | Confirmed | SEC filings, Snowflake blog, Forbes reporting |
| Net worth approximately $1.2B (April 2026) | Confirmed by Forbes tracker | Forbes real-time profile |
| Dropped off 2025 billionaires list | Confirmed | Forbes article, April 2025 |
| Executive compensation from Snowflake | Confirmed | SEC proxy (DEF 14A), annual reports |
| French SCI real estate entities (Grasse area) | Confirmed | Pappers, Societe.com (BODACC filings) |
| Value of French property holdings | Not publicly available | No public valuation on record |
| Current Snowflake shareholding percentage | Estimated (below 5% threshold) | SEC Schedule 13G ceased-reporting filing |
The biggest unknown is his exact current Snowflake ownership percentage. Once a holder drops below 5% beneficial ownership, they stop filing Schedule 13G updates, so the most recent disclosed figure is a floor, not a current number. Forbes likely uses a combination of the last disclosed stake, known vesting schedules, and any reported share sales to estimate his current holding. That estimate is reasonable but not independently verifiable from public documents alone.
Assets, business ties, and lifestyle signals
The clearest lifestyle signal is the French property structure. The INOYB1 SCI is registered at an address in Grasse (12 chemin des paroirs, 06130 Grasse), and the creation of three separate SCI entities (INOYB1, 2, and 3) between 2021 and 2024 suggests an active approach to building a real estate portfolio in France. Grasse sits about 15 kilometers inland from Cannes and is surrounded by high-value residential areas on the Côte d'Azur. Using SCI structures in that region is consistent with high-net-worth property ownership.
Beyond real estate, his primary business tie is Snowflake. The company's market cap has fluctuated between roughly $20 billion and $100 billion since the IPO, so even a small ownership percentage translates to significant wealth. There is no public record of major investments in other companies, board roles at large firms, or luxury brand affiliations of the kind more typical of wealth profiles on this site. His profile is a tech-founder story more than a fashion or luxury dynasty story, though his French roots and Côte d'Azur property ties place him in a recognizable category of wealthy French nationals living at least part-time in the south of France.
How to verify and update his net worth today
If you want to check or update this figure yourself, here is exactly what to look at.
- Check Forbes' real-time billionaires tracker at forbes.com/real-time-billionaires and search for Cruanes. The page shows the last update date so you know how fresh the number is.
- Look up Snowflake's current stock price (ticker: SNOW on NYSE) and compare it to where it was when Forbes last updated the profile. If SNOW is up 10% since then, adjust the estimate up 10%. It's roughly that linear at this ownership level.
- Search the SEC EDGAR full-text search (efts.sec.gov) for 'Thierry Cruanes' to find the most recent Schedule 13G or proxy filings that disclose his ownership stake or compensation.
- Check Snowflake's most recent DEF 14A proxy statement on EDGAR. The executive compensation table will list Cruanes' base salary, bonus, and equity awards for the most recent fiscal year.
- For French assets, search Pappers.fr for 'Cruanes Thierry' to see if any new SCI entities have been incorporated or if existing ones have been modified.
- Cross-reference with Bloomberg Billionaires Index if you have access, as they sometimes carry different ownership assumptions than Forbes and can give you a useful second data point.
The most important thing to watch is Snowflake's stock. That is the single biggest lever on his net worth. If you are searching for Thierry Guibert net worth, this same approach to checking the underlying stock-driven value will be the most accurate way to estimate it over time. Everything else (executive comp, French property) is a rounding error compared to what happens when SNOW moves 20% in either direction. Anyone tracking his wealth seriously should have a standing alert on the stock price and revisit the Forbes tracker quarterly.
Where Cruanes fits among French wealth profiles
Most of the French wealth profiles tracked on this site are rooted in luxury goods, fashion, or long-established business dynasties. Cruanes is different: his fortune came from Silicon Valley-style technology entrepreneurship, which is less common among France's ultra-wealthy but not unprecedented. His profile is closer in structure to that of a tech-sector figure than to someone like a fashion executive or a Côte d'Azur property developer. That said, the combination of a U.S.-listed tech fortune with French SCI property structures in the south of France is actually a recognizable pattern among wealthy French nationals who built careers internationally and then diversified assets back home. Other French wealth profiles on this site, including figures in adjacent business sectors, often show similar patterns of international earnings paired with French real estate holdings. If you are comparing other French entrepreneurs' wealth figures, you may also want to review Thibaud Hug de Larauze net worth for a similar “net worth at a glance” benchmark.
The bottom line: Thierry Cruanes is a genuine billionaire (or very close to one depending on the day), his wealth is verifiable through public filings, and the $1.2 billion Forbes figure is the best publicly available estimate as of spring 2026. The number will keep moving with Snowflake's stock, so treat any specific figure as a snapshot rather than a permanent fact. This closely matches what you will see when searching for thibaud crivelli net worth as a related net-worth-tracking comparison point.
FAQ
Why does Thierry Cruanes net worth change so fast even if he has no new business deal?
For him, the main driver is Snowflake stock price. Even without new disclosures, a daily market move can shift the equity-based valuation by tens or hundreds of millions. That is why Forbes numbers are best treated as day-by-day snapshots rather than stable facts.
Is the Forbes “real-time” estimate for Thierry Cruanes net worth exactly what he owns today?
Not exactly. Forbes starts from publicly disclosed ownership and then uses assumptions for anything not continuously filed, such as updated holdings after dilution, pledged shares, or unreported sales. If the latest disclosed stake is older than the estimate’s date, the current percentage is inferred rather than directly verifiable.
How can his ownership be “unknown,” even though there are SEC filings?
Once a person’s beneficial ownership drops below certain reporting thresholds, they may stop filing the same recurring forms (like Schedule 13G). That creates a public record gap, so the most recent disclosed figure becomes a floor, not a current measurement.
Could Thierry Cruanes net worth be higher or lower than the $900 million to $1.0+ billion range?
Yes, depending on how much unobserved selling, dilution, or liquidity constraints occurred since the last filings. Forbes may also apply discounts when shares are pledged or when ownership percentages imply less liquid exposure. Small percentage differences matter a lot at Snowflake’s market caps.
Do his French SCI property entities mean he is not actually a billionaire from tech equity?
Not necessarily. The SCI listings point to real estate structure, but the article’s core valuation is tied to Snowflake equity. In practice, the real estate would usually act as a diversification layer, while the majority of “net worth headline” figures still come from public-market stock.
Are the SCI entities the same as personal ownership of property in France?
Not always. An SCI is typically a separate legal entity that can hold real estate, with value reflected through ownership in the SCI rather than directly through public property listings. Without published balance sheets or appraisals, it is hard to translate SCI involvement into a dollar estimate.
What stock move would have the biggest impact on Thierry Cruanes net worth estimates?
A sustained move in Snowflake (SNOW) around 25 to 30% is especially impactful because it can push his estimated holdings across major headline thresholds, including whether he appears on billionaire lists. The estimate is roughly proportional to the stock value of his remaining stake.
If Snowflake’s stock drops 25% one week, does that mean his net worth dropped the same amount?
Not perfectly, but it is a close approximation for equity-only wealth. Offsets could include partial hedging, share sales, or changes in the assumed discount/ownership model. Still, the stock price is the dominant lever, so short-term moves largely drive the headline change.
How should I interpret Thierry Cruanes executive compensation versus his net worth?
His salary and bonuses are real, but they are typically small compared with the value of founder-equity in a large IPO. For a CTO co-founder, compensation details matter mainly for understanding cash flow and confirmation of role, not for explaining the bulk of the net worth figure.
Where do unvested equity and prior vesting schedules fit into the estimate?
Founders often receive shares with vesting and dilution over time. Forbes-style estimates can incorporate vesting and dilution assumptions to approximate today’s vested holdings. If vesting schedules changed or if share sales occurred, the inferred current stake can differ from what any single filing might reveal.
What is a common mistake people make when estimating Thierry Cruanes net worth themselves?
Using an outdated ownership percentage without updating for dilution or threshold-based reporting changes. Even if you calculate a correct value from market cap, you can still be far off if the assumed shareholding is no longer current.
If I want to track Thierry Cruanes net worth, what practical routine should I follow?
Use Snowflake’s price as the primary signal, and then check Forbes’ updated snapshot periodically (quarterly is usually a reasonable cadence). Also review SEC filings only when new disclosures appear, since the latest filed stake can lag behind real-time ownership changes.
Does his Swiss or French citizenship affect how his net worth is reported?
Citizenship mainly affects how profiles are categorized, not how equity value is calculated. The valuation mechanics are driven by ownership stake in a U.S.-listed company plus any applied discounts, while the French SCI information is typically used to contextualize diversification rather than headline equity valuations.
