Louis Devaleix Net Worth: Estimate, Sources, and Verification Steps

Louis Devaleix is a behavioral health entrepreneur and co-founder of Dazos, a software company built specifically for the addiction treatment and behavioral health industry. His net worth is not publicly verified by any primary financial disclosure, but working from what we know about his career exits and company funding, a realistic estimate sits somewhere in the range of $10 million to $50 million. The widely circulated figures of $500 million (CineNetWorth) and $1.5 billion (MoonChildrenFilms) are almost certainly inflated and unsupported by any traceable methodology. Here is how to think about all of this carefully.

Who is Louis Devaleix, exactly?

This is genuinely the first thing to sort out, because the name appears in several different contexts and the spelling varies across sources ("Devaleix," "De Vaelix," "DeValeix"). The Louis Devaleix relevant to wealth searches is a U.S.-based entrepreneur with a finance and accounting background. His full legal name, as shown in corporate registry records, is Louis Charles Guy Devaleix. He holds a BS in Accounting and Finance from Tulane University and an Executive MBA from the University of Chicago Booth School of Business (completed around 2015). Those credentials place him firmly in the business and finance world, not entertainment or politics.

Before Dazos, Devaleix co-built Harmony Recovery Group alongside David Farache. That organization was sold to Thrive Healthcare, with the deal announced in November 2022. After that exit, the pair channeled their focus into Dazos, a behavioral health software platform they had been developing since 2018. Dazos now serves roughly 1,500 facilities across the United States, and in May 2025 closed a $25 million Series A round led by Radian Capital.

One thing worth noting: different pages on the Dazos website label Devaleix as both "Co-founder & COO" and "Co-founder & CEO" depending on which section you look at. The Behavioral Health Business press coverage from May 2025 calls him "President and co-founder." This kind of title inconsistency is common at founder-led startups and does not meaningfully change the wealth analysis, but it does explain why some sources describe him differently.

He also appears in a completely separate context: competitive polo. USA Polo Association records show his handicap was raised from 1.5 to 2 as of December 2025, and he plays under the Dazos La Fe team name. The Louis Devaleix polo net worth angle you sometimes see in searches simply reflects the fact that polo is an expensive sport associated with high-net-worth individuals, so his participation reinforces the wealth narrative. It is not a separate income source.

Why people search his net worth in the first place

Most people searching for the net worth of a business figure like Devaleix are trying to answer one of three questions: Is this person legitimately wealthy? How big is the company they run? And how did they build that wealth? Those are all fair questions. For entrepreneurs tied to private companies, the "net worth" figure is really a proxy for how much their ownership stake is worth if the company were sold or went public today.

The general framework works like this: take the estimated value of the company, multiply by the founder's ownership percentage, then add any liquid assets from prior exits, real estate, investments, and so on. The problem is that for private companies, every one of those inputs is either unknown or estimated. That is why you get such wild variation across wealth-estimate websites. They are essentially making up the inputs and presenting the result as fact.

If you are trying to understand how business-driven wealth gets built and tracked, the same principles apply whether you are looking at a startup founder or, say, tracing Louis François Cartier's net worth through generations of a luxury brand. The core question is always: what assets does this person control, and what are those assets worth today?

What the net worth estimates actually say (and what to trust)

Two sites circulate specific numbers for Devaleix. CineNetWorth puts the figure at around $500 million and includes a birthdate claim of October 12, 1980. MoonChildrenFilms goes further and claims $1.5 billion. Neither site shows a transparent methodology, cites primary financial documents, or links to verifiable business filings. These are secondary estimate sites, and for private-company subjects with no public disclosure obligations, they are essentially guessing.

A more grounded approach starts with what we actually know. Dazos raised $25 million in a Series A. Early-stage behavioral health software companies at the Series A stage are typically valued somewhere between 5x and 15x revenue, depending on growth rate and margins. Without knowing Dazos' revenue or Devaleix's ownership percentage, you cannot derive a precise figure, but you can set a ceiling. Even at a generous $100 million post-money valuation and a 50% founder stake (both probably high), Devaleix's paper equity in Dazos alone would be around $50 million. Add proceeds from the Harmony Recovery Group exit, which have not been disclosed publicly, and you might land in the $20 million to $60 million range for a realistic combined estimate.

That is a far cry from $500 million or $1.5 billion. The billion-dollar figures would require either undisclosed asset wealth, a company valuation multiple that is not supported by available data, or a simple fabrication. Until Dazos goes public or someone discloses cap table information, treat those large numbers as speculation.

Is Louis Devaleix on Forbes?

As of April 2026, Louis Devaleix does not appear on the Forbes Billionaires list or the Forbes 400. That is actually useful information, not a gap. Forbes tracks individuals with confirmed net worth above roughly $1 billion (for the billionaires list) or above approximately $400 million (for the Forbes 400). The absence of any Forbes profile is a strong signal that his wealth has not been independently verified at those thresholds.

When Forbes does profile a business figure, their pages display a "Real Time Net Worth" figure with a precise "as of" timestamp and a "Last Updated" line. That metadata is what makes Forbes data useful: you can see how current the estimate is and what methodology class it falls into (index-tracked vs. reported). For anyone in Devaleix's wealth tier, Forbes simply would not have enough primary evidence to publish a verified figure. That is not a slight; it just reflects that Series A startups do not generate the kind of public financial disclosure that Forbes indexes require.

By contrast, think about how Bloomberg's Billionaires Index works: it ties wealth estimates to specific, named assets in a defined index, with traceable price inputs. That level of rigor is what separates credible wealth reporting from the aggregate-and-publish approach used by the net-worth blog circuit. For figures like Devaleix, credible business press (such as Behavioral Health Business or industry funding databases like CB Insights) will always be more reliable than standalone wealth-estimate sites.

His business background and how the money was made

Devaleix's wealth path follows a classic operator-to-exit-to-reinvest model. He and David Farache built Harmony Recovery Group into a sizable behavioral health organization on the East Coast. The sale to Thrive Healthcare, announced in November 2022, was the probable primary liquidity event. Private behavioral health facility sales vary widely, but large multi-site operators have transacted at multiples in the 6x to 10x EBITDA range in recent years. Without knowing Harmony's financials or Devaleix's ownership stake, the exit proceeds remain unquantified but are likely meaningful.

After that exit, Dazos became the primary vehicle. The company was founded in 2018, so Devaleix was effectively running two things in parallel before the Harmony exit freed him to focus entirely on Dazos. The $25 million Series A, announced May 14, 2025, with Radian Capital as lead investor, confirms institutional validation of the business. Dazos sells software to behavioral health facilities, and with roughly 1,500 U.S. facilities already using the platform, there is a recurring revenue base that would support further fundraising or an eventual acquisition.

His finance background is directly relevant here. A Tulane accounting degree followed by a Booth Executive MBA is exactly the training you would expect from someone who built an operator business and then pivoted to a SaaS model. This is not someone who inherited a fortune or stumbled into wealth; the career arc is deliberate and sequential.

For context on how other founders with French-connected names have built wealth through a mix of entrepreneurship and exits, the profile of Louis Tetu's net worth offers a comparable case study in tech-driven founder wealth with similarly opaque private-company valuations.

How age and career timing affect the estimate

CineNetWorth lists Devaleix's birthdate as October 12, 1980, which would put him at 45 years old in April 2026. If that is accurate, his career timeline makes sense: Tulane graduation around 2003, Booth MBA completed around 2015, Harmony Recovery Group built and exited by late 2022, Dazos Series A in 2025. That is a mid-career arc, not a dynastic or inherited wealth story.

Age matters for net worth estimates because it tells you how much time a founder has had for equity to mature, exits to compound, and assets to diversify. At 45, Devaleix is old enough to have had one meaningful exit but likely not old enough to have accumulated multiple generational cycles of wealth. This is another reason why the $1.5 billion figure does not hold up: the timeline simply does not support that level of compounding for someone with one disclosed exit and one Series A company.

Compare this to someone like François Legault's net worth, where a longer career and political tenure provide a richer evidence base for estimating accumulated wealth. For younger or mid-career founders, the uncertainty bands around any estimate are simply wider.

One more timing note: Dazos is currently in a growth phase post-Series A. That means Devaleix's equity is still largely illiquid. His paper net worth will fluctuate significantly depending on whether Dazos raises further rounds, gets acquired, or continues to scale independently. Any estimate you see today is a snapshot of a moving target.

Comparing the main sources: which ones to use

How to verify and stay current

Here is a practical workflow you can repeat whenever you want to check whether Devaleix's estimated net worth has changed. Start with a Forbes search to confirm he still does not have a profile. Then search Behavioral Health Business, Crunchbase, and CB Insights for any new Dazos funding rounds, acquisitions, or IPO filings. A new funding round at a disclosed valuation would let you model his stake more accurately. An acquisition announcement would potentially give you a sale price to work with.

For corporate registry verification, The Company Check and Tofler both list "Louis Charles Guy Devaleix" as a director for Dazos Private Limited (CIN: U72200DL2021PTC384454, incorporated July 30, 2021 in India). This is a legal entity worth noting for disambiguation purposes, though it does not itself tell you his personal net worth. These registry sites confirm identity and corporate linkage but are not wealth sources.

If you are searching for SEC filings, you will not find personal wealth disclosures for Devaleix because Dazos is a private company with no public reporting obligations. SEC filings become relevant only if Dazos ever goes public or if Devaleix holds a significant stake in a publicly traded company. That is a key limitation of the private-company net worth problem.

Finally, cross-check any number you find against the career timeline. If a site claims $1.5 billion for someone with one private exit and a Series A company, that number needs an explanation. Where did the other $1.4 billion come from? If the site cannot answer that, discount it. The same critical lens applies whether you are looking at a behavioral health entrepreneur or checking the figures on someone like Louis Saha's net worth on Forbes, where sports career earnings and post-career ventures need to be traced separately.

Names that might be causing confusion

A quick note on disambiguation: searches for "Louis Devaleix" sometimes return results mixed with other people named Louis in business or public life. There is no meaningful connection between this Devaleix and, for example, Louis José Houde's net worth (the Quebec comedian) or Louis Morissette's net worth (the Quebec entertainer). If your search returns results about a French-Canadian public figure or a performer, you are looking at a different Louis entirely.

Similarly, Mervin Sidney Louque Jr.'s net worth sometimes appears in adjacent searches due to similar phonetic patterns in the name. These are unrelated individuals. The Louis Devaleix relevant to this article is specifically the behavioral health entrepreneur and Dazos co-founder based in the United States.

Bottom line on Louis Devaleix's net worth

The most defensible estimate for Louis Devaleix's net worth today is somewhere between $10 million and $50 million, built primarily from the Harmony Recovery Group exit and his equity stake in Dazos. That range is wide because the key inputs (exit proceeds, ownership percentage, and current Dazos valuation) are not publicly disclosed. The figures circulating on net-worth blogs ($500 million to $1.5 billion) are not supported by any traceable evidence and should be treated with skepticism.

He is not on Forbes. He runs a private company. His wealth is real but illiquid and tied almost entirely to Dazos' future performance. The best way to stay current is to monitor Dazos' funding news through VC databases and business press, and to revisit Forbes periodically in case a future exit or IPO pushes him into a trackable wealth tier. Until then, any precise number is an educated estimate, not a verified fact.
