Sergio Ducoulombier Net Worth: Estimated Range and How It’s Derived

Sergio Ducoulombier's net worth is not publicly disclosed, and no verified figure exists in any regulatory filing, court record, or official financial disclosure. If you are specifically looking for Sergio Danguillecourt’s net worth, this article’s verified-methods and evidence thresholds can help you sanity-check any figures you see elsewhere. Based on what can be pieced together from public records, his career as founder and CEO of Slip Cash, his patent inventorship, and his involvement in earlier financial services ventures, a reasonable estimated range sits somewhere between $1 million and $10 million, with the upper end depending heavily on the current valuation of Slip Cash and any equity he retains. That range should be treated as a working estimate, not a confirmed figure, for reasons this article will walk through in detail.

Who Sergio Ducoulombier is and why people search his wealth

Sergio Nicolas Ducoulombier became a recognizable name largely because of his relationship with Alexandra Jarvis, a real estate agent featured on the Netflix reality series 'Selling the OC.' That connection put him in front of a large audience that had no prior reason to know who he was, and the natural follow-up question for many viewers was: what does this guy actually do, and how much is he worth?

Beyond the reality TV context, Ducoulombier has a traceable professional identity. He is the founder and CEO of Slip Cash, a fintech company that produces hardware and software enabling cashless peer-to-peer payments from mobile devices. A patent assigned to Slip Cash Holdings LLC names him as inventor, which confirms his technical and operational involvement in the business rather than just a nominal leadership title. Entertainment profiles sourced from outlets like Yahoo and AOL describe his background through references to his LinkedIn profile, noting education and a period of military service, though those biographical details have not been independently verified through primary records.

There is also a regulatory layer to his history that any honest net worth discussion has to acknowledge. The California Department of Financial Protection and Innovation (DFPI) issued a Desist and Refrain Order dated September 21, 2020, directed to Sergio Nicolas Ducoulombier and entities listed as My Liquid Hedge Fund, Liquid Hedge, and Liquid Currencies. The BBB lists My Liquid Hedge Fund / Liquid Currencies as a sole proprietorship with Ducoulombier as principal, also starting on the same date. That enforcement action is a matter of public record and is relevant both to his professional history and to any assessment of financial exposure or liabilities.

Income sources worth considering

When building a net worth estimate for someone like Ducoulombier, you have to think through each plausible income source separately, because lumping them together without distinguishing verified from speculative produces a useless number.

Slip Cash: the primary business

Slip Cash is the most concrete income and asset driver on the table. As founder and CEO, Ducoulombier would typically hold an equity stake in the company, draw a salary, and potentially receive other compensation tied to the company's performance. The company has at least one granted US patent (US12260390B2, assigned to Slip Cash Holdings LLC), which signals meaningful investment in intellectual property. However, Slip Cash does not appear to be publicly traded, which means its valuation is entirely private. Without a disclosed revenue figure, funding round announcement, or acquisition event, any estimate of the company's value and therefore Ducoulombier's equity stake requires assumptions based on comparable fintech startups, which can vary enormously.

Patent and IP ownership

The patent assigned to Slip Cash Holdings LLC is a real, verifiable asset, but it doesn't translate directly into a dollar figure. Patents have value only when they generate licensing revenue, protect a product generating sales, or become part of a transaction. Until any of those events are disclosed, patent ownership is a qualitative signal of technical depth rather than a quantifiable wealth component.

The Liquid Currencies / My Liquid Hedge Fund chapter

The earlier financial services venture adds complexity rather than value to the picture. The DFPI enforcement action indicates that Ducoulombier was operating or associated with investment advisory activity without proper authorization. A Reddit thread (not a primary source) mentions a '$2.7 million damages judgment' involving a 'Sergio Nicholas Ducoulombier' and an entity called Liquid Equity Inc, but this has not been corroborated against actual court dockets and should not be treated as fact until verified. If any such judgment is real and unpaid, it would reduce net worth, not inflate it. This is exactly the kind of claim that requires primary-source verification before it gets incorporated into any estimate.

Other potential income and assets

A SLIP trademark filing (serial 88573871) on Justia lists 'Ducoulombier, Karina' as the employee name for a mark related to NFC-based credit card payment processing. This suggests family involvement in the business ecosystem, but it doesn't provide direct insight into Sergio's personal income. Real estate holdings, personal investments, or other business interests are not documented in any public record reviewed here.

How net worth is actually calculated for private individuals

For public company executives, net worth estimation is relatively straightforward: you look at disclosed stock holdings, add any known real estate from property records, and layer in salary data from proxy filings. For private business owners like Ducoulombier, the process is much messier.

The standard method for valuing a private company, as described in methodologies used by publications like Forbes for their private wealth estimates, is to apply a revenue or earnings multiple derived from comparable public companies, then apply a liquidity discount, typically ranging from 20 to 40 percent, to account for the fact that private equity can't be sold instantly. The problem is that this method requires knowing the company's revenue or earnings, which are not publicly disclosed for private firms. That means any estimate of Slip Cash's value is essentially a proxy built on assumptions: assumed revenue tier, assumed growth stage, assumed comparable peer group.

Sites like Net Worth Spot acknowledge they use a combination of publicly available data and a proprietary algorithm. Bloomberg's Billionaires Index relies on disclosed holdings and stock prices. Neither approach maps cleanly onto someone like Ducoulombier, whose wealth is tied to a private company with no disclosed financials. The result is that celebrity-oriented net worth aggregator sites will often produce wildly different numbers, some claiming 'over $50 million USD' without any disclosed methodology. That kind of figure is not verifiable and should not be repeated as fact.

A range-based estimate and the assumptions behind it

Given what is publicly verifiable, here is how to think about Ducoulombier's estimated net worth range as of April 2026:

The wide range reflects genuine uncertainty, not a lack of effort. For comparison, other figures in the French and international business and entertainment space, such as those profiled elsewhere on this site, often have more traceable income streams through disclosed television contracts, public company affiliations, or long-form media careers that generate documented royalties. Ducoulombier's profile is predominantly tied to a single private company at an early stage, which makes precision impossible without insider data.

The upper end of the range ($8-10M) would only apply if Slip Cash has achieved meaningful revenue scale and Ducoulombier retains a majority equity stake, neither of which is confirmed. The lower end ($1M or below) becomes more plausible if the DFPI enforcement action resulted in significant financial penalties or if the Reddit-referenced judgment is real and has reduced net assets. Until those facts are clarified via court records, the honest answer is a midpoint scenario of roughly $1 million to $5 million. If you are also trying to understand silvestre dangond net worth, use the same discipline: look for primary-source documentation and treat gaps as uncertainty rather than proof.

Common claims vs. what the evidence actually supports

Several entertainment and celebrity net worth sites have published specific figures for Ducoulombier, including one claiming 'over $50 million USD. If you are specifically searching for Gregorio Duvivier net worth, be skeptical of similar high numbers unless you can trace them to primary documentation 'over $50 million USD. ' There is no publicly available evidence to support that number. No funding announcement, no acquisition, no IPO, no SEC filing, and no court record places his verified assets anywhere near that range. These sites typically generate estimates algorithmically from social media signals, brand associations, and name recognition, none of which are reliable proxies for actual wealth.

It is also worth noting the name confusion risk. A document surfaced during research references an 'Eric Ducoulombier' in a completely unrelated European banking context. When searching for records tied to a relatively uncommon surname, false matches are a real hazard. Any record you find should be verified to include the full name 'Sergio Nicolas Ducoulombier' and, where possible, a corroborating detail like a business name, address, or date before being treated as relevant.

The most verifiable claim about Ducoulombier's financial life is actually a negative one: the DFPI Desist and Refrain Order is a documented regulatory action that any serious due-diligence review of his financial history must include. It does not prove he is broke, but it does indicate that his earlier financial services venture ended under regulatory pressure, which is material context.

How to verify and update this estimate yourself

If you need a more current or more precise picture, here is a practical checklist of what to check and where:

1. Search the USPTO patent database (patents.google.com or USPTO.gov) for 'Ducoulombier' to identify any new patent filings or grants tied to Slip Cash Holdings LLC, which would signal ongoing R&D investment and business activity.
2. Check the DFPI enforcement actions page (dfpi.ca.gov) directly for any updates to the Sergio Nicolas Ducoulombier / My Liquid Hedge Fund / Liquid Currencies record, including whether the desist and refrain order has been resolved, escalated, or supplemented.
3. Search PACER (the federal court records system) or Justia's court database for 'Sergio Ducoulombier' or 'Liquid Equity Inc' to verify or refute the Reddit-referenced judgment claim. A real judgment would appear as a docketed case with a damages amount.
4. Look up Slip Cash on Crunchbase, PitchBook, or LinkedIn for any disclosed funding rounds, investor names, or revenue signals. A seed or Series A announcement would dramatically change the valuation basis.
5. Search California's Secretary of State business registry (bizfileonline.sos.ca.gov) for Slip Cash Holdings LLC to confirm active status, registered agents, and any ownership filings.
6. Search the USPTO Trademark database (tmsearch.uspto.gov) for the SLIP trademark (serial 88573871) to check current status, owner of record, and any assignments that might signal business changes.
7. If Ducoulombier or Slip Cash has appeared in any SEC filing (e.g., as a named investor or party in a disclosure), the SEC EDGAR full-text search (efts.sec.gov) can surface those connections.
8. Treat any celebrity net worth site figure as a starting hypothesis, not a conclusion. Cross-reference it against at least two primary sources (patent records, court records, regulatory filings, or funding announcements) before accepting it.

One practical note on timing: net worth estimates for private business owners can shift significantly based on business events that happen in a single quarter. A funding round, a licensing deal, or an acquisition could move Ducoulombier's real net worth by millions in either direction without any public announcement. The estimate in this article reflects the state of publicly available information as of April 2026 and should be revisited if any of the above sources produce new data.

For context, this site covers a range of French and international figures whose wealth is equally difficult to pin down precisely. Figures in entertainment and media often have more traceable income through public contracts and royalties, while business founders like Ducoulombier sit in a more opaque category where the honest answer is always a range with explicit caveats, not a single confident number. If you are trying to verify michel sardou net worth specifically, the same emphasis on primary-source documentation and uncertainty will help you avoid inflated or untraceable claims. That transparency is more useful than a false precision that gives you confidence without giving you accuracy.
