Thirty years of companies, one unicorn, a €22 million exit, a liquidated school and a group going public at fifty-two. His method fits in one sentence: spot a technological shift very early, then put all his capital and all his energy into it.
That €375 million figure needs an immediate caveat, and he asks for it himself: it is an estimate by Challenges, picked up by RTL in September 2025, matching the assumed value of his holdings — Ledger above all — and not a sum sitting anywhere. Éric Larchevêque does not really dispute the calculation, but insists this wealth is largely “virtual”. So we keep the figure while presenting it for what it is: an estimated value of illiquid assets.
Born on 30 September 1973, French. The civil details appearing in his companies' official filings are consistent with one another, which is far from the case on every profile on this site.
He grows up in Vierzon, in the Cher. His family owned a porcelain business there, which eventually disappeared. He has explained that the collapse marked him deeply — and thirty years later, that is precisely the town he chooses to reinvest in.
He leaves ESIEE Paris with training in electronics, microelectronics and information architecture. His internships in large companies mostly convince him of one thing: he does not want to be an employee. He sees the internet arriving around 1995 and starts his first web venture in 1996, practically as he graduates.
He founds Montorgueil SAS, built around dating sites, adult content, affiliate marketing and internet payment and monetisation systems. Not a prestigious sector, and he owns it openly today: what he saw was an extremely profitable market opportunity in the early web.
The company reaches around twenty million euros in revenue, self-funded and profitable. He sells it in 2007 to Rentabiliweb, for an amount documented by Le Monde at twenty-two million euros.
His path turns distinctly unusual. He moves to Romania, where he sets up offshore software development, then to Latvia, to Riga. There he takes part in developing the Dodo Hotel, around a hundred rooms. Before Bitcoin, then, he has already touched the internet, affiliate marketing, payments, property and hospitality.
With the capital and freedom the sale gives him, he goes and does something else entirely: the international poker circuit, seriously, for two years. He stops in 2009, finding poker too emotionally expensive and preferring to spend his energy building a lasting asset.
An app that scans a barcode and compares prices across retailers. The service reaches around two million users according to his professional biographies, raises money, then is bought by HighCo in 2013-2014. The French government itself lists Montorgueil and Prixing among the companies he created and sold.
He reads everything he can find and quickly becomes convinced that Bitcoin is both a technological and a monetary innovation. But he does not yet know what business to build around it. His answer is unusual: rather than shipping a product, open a place where the community can meet.
With Thomas France, he opens 220 square metres at 35 rue du Caire in Paris: buying and selling bitcoin, talks, coworking, training, meet-ups. One of the very first physical venues in Europe entirely devoted to Bitcoin, at a time when most people still treat the subject as an obscure curiosity.
Several French teams working on securing Bitcoin pool their technologies. Éric Larchevêque becomes one of Ledger's eight co-founders and takes charge of the company. He recalls himself having launched it with seven other co-founders.
Pascal Gauthier becomes chief executive of Ledger. Éric Larchevêque takes the Executive Chairman role to focus on strategy. French registers show he ceases to be a legal officer of the company in 2021.
He joins the very first French season of the show and becomes one of its long-standing investors. He is still taking part in the 2026 season, alongside Marc Simoncini, Anthony Bourbon, Kelly Massol, Alice Lhabouz, Jean-Michel Karam and Jonathan Anguelov.
Ledger raises 380 million dollars in June at a valuation above 1.5 billion. That same year, he confirms a liquidity event, selling part of his shares, and says he paid close to ten million euros in tax on the capital gain.
The computing school he helped create in Vierzon fails to find its economic balance. The company is put into court-ordered liquidation, with the date of insolvency set at 16 June 2025.
With Nathan B. Pissaro, and with Tony Parker's backing, he launches a new ecosystem originally presented as The Bitcoin Society. In October 2025 he also creates FINANCIÈRE LARCHEVÊQUE, his holding company, of which he is president.
Euronext makes the deal official. TBSO raises around eight million euros and starts with a market capitalisation of about 30.2 million euros, under the TBSO ticker in Paris.
Physical devices holding the private keys that let you own bitcoin and other crypto assets. The keys sit neither on an exchange nor simply on the owner's computer.
A first round of 1.3 million euros as early as 2015, around 7 million dollars in 2017, then 75 million in 2018. And in June 2021, the tipping point: 380 million dollars at a valuation above 1.5 billion. In 2023 the company raises roughly another hundred million euros while holding a valuation of about 1.3 billion.
More than seven million devices sold, across 180 countries. This is clearly the business that created most of his current wealth, and by far the largest asset on this page.
Co-founder and long-standing shareholder — not chief executive. Pascal Gauthier runs the company and also chairs the group. The exact share of capital held by Éric Larchevêque is not public, and that is precisely why his wealth cannot be recalculated from the outside.
By the time he creates Ledger, he already has nearly twenty years of entrepreneurship behind him. That is what most portraits forget to mention.
Online dating, adult content, affiliate marketing and payment systems. Around twenty million euros in revenue, with no outside funding, before a sale to Rentabiliweb. Le Monde documents the price at twenty-two million euros; some biographies say twenty-five, and we keep the figure from the strongest source.
€22M exitThis is not a Sunday game with friends: the Hendon Mob database records $587,307 in live tournament winnings across twenty-five recorded results, with a single biggest cash of $144,376 and final tables at major European tournaments. He says what he kept from it was risk management, emotional control, probability and decision-making on incomplete information.
$587,307 in winningsA barcode-scanning price comparison app, around two million users, a funding round, then an acquisition by HighCo. The sale is confirmed — it appears even in official French government communications — but its amount has never been reliably made public.
Amount not publicThe buying and selling side of La Maison du Bitcoin grows and becomes Coinhouse from 2018 onwards, the first French company registered as a PSAN with the AMF. He no longer runs it: Nicolas Louvet has led it for a long time. TBSO today puts forward a valuation above 100 million euros — a figure communicated by his own ecosystem, not a guaranteed value.
First PSANIt is one of the rare places where you can measure the gap between what gets said on television and what gets signed afterwards.
In February 2026 he states that he actually put in around 2.4 million euros across some twenty companies from the show. That is the figure to keep, because it matches money genuinely paid out.
He had initially committed to thirty-two deals; twelve did not happen, after checks or after the entrepreneur withdrew. A deal on television is not money invested: after the show, his teams review the trademark, the legal side, the accounts, the terms of sale, the shareholding and the tax position.
He acknowledges that a significant share of the funded start-ups no longer exists: asked by Le Parisien in 2026, he estimates that around a third of his closed deals were still active. That is the reality of angel investing — many failures, and a few wins that have to pay for everything.
Unlike almost everything else on this site, this group is listed: anyone can buy shares in it.
With Nathan B. Pissaro and Tony Parker's backing, they buy control of an old listed company, Société de Tayninh, then use it to carry out a reverse takeover. The shell is turned into TBSO. On 30 June 2026, Euronext makes it official: around eight million euros raised, 30.2 million in opening market capitalisation.
Euronext ParisThe project has moved beyond the initial Bitcoin Society concept: TBSO now presents itself as an ecosystem combining artificial intelligence, fintech, entrepreneurship and investment. Its remit also allows it to hold bitcoin directly on its own account, preserving the original Bitcoin treasury dimension.
AI, fintech, BitcoinAimed at company leaders: more than forty experts, daily live sessions, a community and coaching, covering marketing, finance, sales, AI, recruitment, legal, branding, productivity, fundraising and leadership. The product includes Kate, a conversational agent that knows the member's business — model, goals, past decisions, numbers — and is trained on the content produced by the experts. On the audience side: 719 active members announced on 31 December 2025, and a free event held in March 2026 said to have gathered more than 15,000 entrepreneurs online in a single day.
719 members at end 2025A private club co-founded with Nathan B. Pissaro, combining financial education, experts, private opportunities and analysis across several asset classes: Bitcoin and crypto, start-ups, private equity, public markets, real assets. Its stated promise is to take no commission on the amounts members invest.
Private clubTwo figures circulate about this group, and they do not say the same thing. The first: close to four million euros of revenue already secured through SKL and NVST, to be recognised in the 2026 accounts — that is the most interesting data point today. The second: a 2025 net loss of about 1.49 million euros. That second figure does not describe the ongoing business: the structure comes from an old listed company taken over and transformed, and operations only really begin at the very end of 2025. Writing “TBSO loses one and a half million a year” would be wrong.
This is not public relations: he chose to reinvest in the town where he grew up, and one of those projects has just failed publicly.
A Ledger manufacturing site, the ALGOSUP school, the B3 Village by CA Vierzon incubator, and NEST, a science and technology space. Alongside them, the Éric & Iveta Larchevêque endowment fund, devoted in particular to scientific culture for young people.
A computing school training developers over roughly a five-year course. It did not find its economic balance: court-ordered liquidation on 8 July 2025, with insolvency dated 16 June 2025. It is his most recent public entrepreneurial failure, and there is no reason to present it any other way.
Even after the school closed, the goal of creating a small technology ecosystem outside Paris remains a constant in his career. It is one of the rare places where his personal history — a family business collapsing in that same town — meets his strategy as an investor.
It is one of the rare profiles on this site where a serious estimate genuinely exists — and where the person concerned has commented on it himself.
Thirty years of work does not reduce to “he created Ledger and got rich”. The detail teaches more than the summary.
Two books, a podcast, and one professional network far above the rest. Figures recorded in September 2026.
Published on 17 January 2024. Part autobiography, part entrepreneurial philosophy, part field advice: he covers Montorgueil, Romania, Latvia, poker, Ledger and Qui veut être mon associé.
January 2024Published on 5 February 2026, with a foreword by Tony Parker. The book explains Bitcoin, self-custody, the risks, buying and holding long term. Its release obviously accompanies the launch of TBSO and NVST.
February 2026Launched in 2026 with Nathan Pissaro and Tony Parker. The show mixes entrepreneurship, investment, personal journeys, artificial intelligence, media and society. The channel sits at around 17,200 subscribers for 1.53 million views, growing fast.
1.53M viewsLinkedIn is by far his main channel, with around 450,000 followers and near-daily posting on entrepreneurship, AI, Bitcoin, investment, TBSO, SKL and QVEMA. Then come Instagram, @elarch, at around 188,000 followers, and X, @EricLarch, between 94,000 and 95,000. His personal YouTube channel showed around 79,000 subscribers in spring 2026.
≈ 450,000 on LinkedInOne thing sets him apart from the other profiles on this site, and it is about method rather than amount. Marc Lou builds many small software products, Aurélien Amacker built a large SaaS without ever raising, Lucien Cupif turns an audience into an industrial group, Taylor Chiche builds his deals through his network. He spots a technological shift very early, then puts everything into it: the internet in 1996, web monetisation in 1998, mobile and price comparison in 2011, Bitcoin in 2013, crypto hardware in 2014, and today agentic AI, fintech and paid communities. At fifty-two, with wealth estimated in the hundreds of millions, he objectively no longer needs to work — and he is starting again.
It is estimated at around 375 million euros in 2025 by Challenges, a figure picked up by RTL. That estimate matches the assumed value of his holdings, mainly in Ledger, rather than cash: he describes the wealth himself as largely virtual. In 2021, the same source put him at around 300 million.
No. He stepped back from day-to-day leadership in April 2019, when Pascal Gauthier became chief executive, then took the Executive Chairman role. French registers show he ceased to be a legal officer in 2021. He remains a co-founder and long-standing shareholder, and Pascal Gauthier runs the company today.
Twenty-two million euros, an amount documented by Le Monde at the time of the 2007 sale to Rentabiliweb. Some biographies say twenty-five million. Read it carefully: that is the price paid for the company, not necessarily the sum personally banked by its founders.
Yes, roughly between 2007 and 2009, on the international circuit. The Hendon Mob database records $587,307 in live tournament winnings across twenty-five results, with a single biggest cash of $144,376. He stopped in 2009, finding poker too emotionally expensive.
Around 2.4 million euros actually paid out, across some twenty companies, according to what he said in February 2026. He had committed to thirty-two deals on air, but twelve did not close after checks. He estimates around a third of the signed deals were still active in early 2026.
It was placed into court-ordered liquidation on 8 July 2025, with insolvency dated 16 June 2025. The school, based in Vierzon, did not find its economic balance. It is closed: he no longer runs it.
A group listed on Euronext Paris since 30 June 2026, launched in late 2025 with Nathan B. Pissaro and Tony Parker's backing. It came out of the purchase of an old listed company, Société de Tayninh, transformed through a reverse takeover. The group raised around eight million euros for an opening capitalisation of 30.2 million, and brings together two brands: SKL for entrepreneurs and NVST for investment.
He was born on 30 September 1973 in Boulogne-Billancourt, making him 52 years old, and 53 from 30 September 2026. He grew up in Vierzon, in the Cher, and graduated as an engineer from ESIEE Paris in 1996.
