The Ownership Illusion: A New Architecture for Portfolio Resilience

This article is an editorial account of the June 8 event at Decentral House. It is not a commercial communication and does not constitute investment advice.

There is a category of risk that does not appear in a standard investment prospectus. It is not volatility, not liquidity, not even counterparty default in the conventional sense. It is the risk that the assets you believe you own are not, in any meaningful sense, yours. They exist on paper, recorded in a ledger administered by an institution whose interests do not perfectly align with yours, accessible only through channels that can be closed, restricted, or reorganized without your consent. You are, in the language of finance, long the asset but short the access. The financial world has a word for this structural gap, though it rarely applies it with precision: counterparty risk. Most investors carry far more of it than they realize, across a wider range of asset classes than they have considered.

On the evening of June 8, Decentral House hosted TBSO, the Euronext Paris-listed AI and fintech ecosystem co-founded by Éric Larchevêque and Nathan B. Pissaro, for an exclusive keynote and conversation with our Geneva community. The room brought together entrepreneurs and investors who came to hear a framework that most financial advisors do not raise: genuine portfolio resilience requires not just diversification across asset classes, but diversification across the modalities of ownership itself. The question worth asking is not only what you hold, but how it is held, under what legal conditions, and by whose permission.

That framing is harder to dismiss when it comes from people who had to learn it at personal cost.

When the Asset Is Yours but the Access Is Not

Éric Larchevêque took the stage first. As co-founder of Ledger and founder of Coinhouse, he is one of the most prominent figures to have emerged from the European crypto and fintech ecosystem, having helped build the world's leading hardware wallet company and brought genuine self-custody within reach of millions. Wider French audiences know him from “Qui veut être mon associé”, the French version of “Shark Tank” television program, where he sits across founders as an investor.

Today, as founder and CEO of TBSO, he is deep into his next entrepreneurial chapter, and he opened the room with two stories from his own experience:

The first one took place in Luxembourg, where Éric Larchevêque had opened an account, purchased physical gold, and arranged for it to be stored with his private bank. When he later arrived to retrieve his bars, he was informed that he was no longer a welcome client at the institution. The gold was technically his, and the bank's systems confirmed the holding, but the physical asset could not be returned to him without the cooperation of an institution that had decided, unilaterally, that his custom was no longer desired. The eventual resolution required selling at terms he did not choose, on a timeline he did not control, and the lesson was not that gold was a poor investment, it was that gold stored under someone else's roof is, in functional terms, their gold.

The second story strikes even harder: Éric had a relatively substantial sum of funds held with a Latvian bank. He discovered the failure the most ordinary way imaginable: standing at an ATM, attempting a withdrawal that kept declining, repeatedly, without explanation. Later that same day, he learned what had happened: the bank had collapsed, not through market forces but through its own fraudulent misconduct. Over the years that followed, he managed to recover roughly a third of that sum through deposit insurance schemes and protracted legal proceedings, but the rest was gone…

This experience served as a visceral, real-world lesson in the ordinary structural fragility of the banking system: the realization that a depositor’s claim is merely a promise, one that vanishes instantly when the institution behind it fails.

These memories of institutional collapse—the broken promises, the frozen access, the realization that an asset is only as secure as its gatekeeper—were the exact forces that drove Satoshi Nakamoto to create Bitcoin. The genesis block’s permanent timestamp, "Chancellor on brink of second bailout for banks," was a direct indictment of the very fragility Éric had just witnessed. When he encountered Bitcoin on a French online forum in 2013, it was not merely a new technology he was discovering; it was the structural solution to the counterparty risk problem he had lived through. Driven by this understanding, he converted the majority of his holdings into the asset in the following years.

His reasoning was not speculative in the conventional sense, but rather a fundamental property of the asset: Bitcoin, held in self-custody with one's own private keys, is the first asset in the history of finance with no counterparty dependency.

It cannot be frozen, rehypothecated, or withheld by an institution experiencing difficulties. It cannot be made inaccessible by a regulator's instruction or a banker's discretion. "The real value proposition of Bitcoin," he said, "is to give you back ultimate possession of your assets." This was the reason to take the asset class seriously.

This framing matters because it redefines what diversification is actually trying to accomplish:

For most investors, diversification means owning assets that do not move in the same direction at the same time, but if all of those assets are held through the same institutional infrastructure, subject to the same legal jurisdictions and the same counterparty relationships, they are diversified inreturn profile, but not inownership structure.

The distinction becomes visible only in extremis like Éric’s case, when the infrastructure itself comes under stress. By then, the moment to restructure has already passed.

Why Your Portfolio Is Less Diversified Than You Think

Nathan B. Pissaro, co-founder of TBSO and former private banker, approached the same problem from a different analytical angle. His argument was empirical before it was prescriptive: many portfolios that appear diversified are, on closer inspection, exposed to a narrower set of risk factors than their owners assume.

The traditional recommendation for private investors has been a portfolio anchored in equities and bonds, with some real estate exposure. But Nathan drew attention to something the data has made increasingly difficult to ignore.

The MSCI World Index, widely used as a benchmark for developed-market global equity exposure, carries a United States weighting that has exceeded 70% in recent years. Within that US exposure, a disproportionate share is concentrated in a small number of large-cap technology companies. Apple, Microsoft, Nvidia, Amazon, Alphabet, Meta, and Tesla, the group of stocks analysts have come to call the "Magnificent Seven," represented at their peak more than 30% of S&P 500 market capitalization. An investor who believes they hold a broadly diversified equity portfolio is, in practice, significantly long US technology valuations. The geographical breadth appears genuine on the surface, but it masks a deep underlying concentration in a small number of US mega-cap equities.

The bond component of the classic 60/40 portfolio also came under scrutiny. In 2022, government bonds in most major markets fell simultaneously with equities for the first time in decades, weakening one of the key assumptions that had made bonds such an effective portfolio stabilizer. Investors who had constructed their portfolios around that historical relationship discovered that the protection they believed they had purchased had disappeared precisely when they needed it most.

Source: Vanguard analysis, based on Bloomberg monthly total returns in USD from January 1990 to April 2023. Global equities are represented by the MSCI ACWI Index and global bonds by the Bloomberg Global Aggregate Index Value USD Hedged.

The chart makes the 2022 exception visible. In most major equity drawdowns since 1990, global bonds still delivered positive cumulative returns, even when short-term equity/bond correlations were positive. The 2007-08 global financial crisis is the clearest example: global equities fell by roughly 54%, while global bonds gained more than 6%. By contrast, during the 2022 global slowdown, equities and bonds both declined, leaving the traditional 60/40 portfolio without the stabilizing bond cushion investors had come to expect.

The model was not wrong in theory, and the historical data supported it well for a long period. But that period was characterized by generally declining interest rates. When inflation returned, central banks tightened policy, and the macro environment shifted, the stock-bond relationship changed. Portfolios designed for one regime found themselves exposed in another.

Against this background, Nathan introduced what he called the "fourth diversification": the inclusion of asset classes that do not merely have different return profiles, but that operate on genuinely independent logic, outside the cycles of public equity and bond markets. The criterion was not simply low correlation, though low correlation is part of it.

The deeper criterion wasindependence: assets whose value is determined by factors less directly tied to central-bank policy, the earnings trajectory of large-cap technology companies, or the risk appetite of institutional investors managing public-market portfolios. The goal, as he framed it, is to own flows that the market cannot switch off.

Alternative Investment Classes: A Framework for Direct Ownership

The evening moved through a series of asset classes in some detail, with each examined not as a simple investment opportunity but as a distinct ownership structure with its own mechanics, its own relationship to the counterparty question, and its own position in a resilient portfolio.

Physical gold was the first. Nathan's framing echoed what Éric mentioned previously: gold as a concept and gold as a physical asset held in your own possession are fundamentally different instruments. The former is a paper claim on gold, subject to all the counterparty risks of any financial instrument. The latter eliminates those risks, at the cost of requiring genuine custody responsibility. The premium for self-custody is not merely financial. It is the price of sovereignty over the holding itself.

Trading card games, specifically the Pokémon TCG market, represented a more unexpected inclusion that the room received with genuine curiosity. Nathan's argument was demographic before it was financial. The generation that grew up with Pokémon in the 1990s has now reached its peak earning years, and it carries a deep cultural relationship with the cards that is distinct from the nostalgia of any previous collecting wave. The global collectible card market has grown substantially as a result; PSA, the leading grading authority, now authenticates millions of card submissions annually, and the graded-card market has developed the price transparency and liquidity infrastructure that are prerequisites for treating an asset class seriously.

Nathan highlighted a structural feature that informed buyers can use to their advantage: bulk lots of ungraded cards typically trade at discounts of approximately 30% to the sum of their individually graded values. For investors willing to absorb the friction of the grading process, he argued, that discount represents a systematically accessible source of return, distinct from broader price appreciation.

Music royalties occupied a larger portion of the evening, in part because the mechanics are less widely understood than the asset class's reputation might suggest. Nathan's core proposition was that music streaming has transformed what was once a cyclical and unpredictable revenue stream into something resembling a predictable cash flow. Musical tastes, he argued, tend to solidify by our late twenties, making listening habits remarkably stable over time and creating a durable foundation for royalty flows that more closely resemble recurring income than speculative return. A consistent position on a major streaming playlist, in his framing, is more stable than most equity dividends: the songs are played millions of times daily, and the royalty flow reflects that regularity with a reliability that fixed-income investors would recognize immediately.

Nathan described two principal instruments for accessing this market. The first resembles a fixed-income structure, where royalty bonds are secured against catalog revenues and deliver coupon-like yields. The second offers equity-like participation in the upside when a catalog appreciates in cultural and commercial value over time. He cited expected returns on well-managed catalog acquisitions in the range of 25% to 30%, reflecting both the yield and the capital appreciation of catalogs that gain resonance as their underlying songs accumulate cultural longevity. Goldman Sachs, in its analysis of the recorded music sector, has projected global industry revenues approaching $130 billion by 2030, driven by the continued expansion of streaming platforms across emerging markets.

Private debt was presented as the most accessible alternative class for investors already comfortable with fixed-income logic. Nathan described the risk-return spectrum as running from approximately 5% at the conservative end, in structures secured against Swiss real estate collateral, to 12% and above for higher-yielding private loans, with risk scaling accordingly. The key distinction from public bond markets, in his analysis, is the negotiated nature of the terms and the direct relationship between lender and borrower. The global private credit market has grown to approximately $1.7 trillion in assets under management, according to Preqin estimates, as institutional capital has shifted toward the asset class for reasons that are essentially the same as those Nathan described: yields materially above public markets, with documentation providing structural protections unavailable in liquid bond instruments.

Staking on blockchain networks, specifically stablecoins, was addressed with the same measured register as the other classes: yields between 6% and 10% for investors willing to engage with the technical requirements. The risk profile differs from fiat fixed income, but so does the counterparty structure. Staking returns are generated by protocol mechanics rather than institutional promises, which positions the asset class within the evening's broader framework of reducing dependence on intermediary-controlled access.

Pre-IPO secondary markets received the most cautionary treatment of the evening. The opportunity is genuine: accessing shares in late-stage private companies before public listing can generate significant returns, and the secondary market for these positions has matured considerably over the past decade. But Nathan identified a structural problem in how most investors gain access to it: the proliferation of intermediary platforms, feeder funds, and special purpose vehicles has created a fee architecture that can consume a substantial portion of the underlying return before it reaches the investor. He cited the example of Anthropic, a company that has attracted significant investor interest and whose secondary market valuations have moved dramatically in a short time. Investors accessing that position through multi-layer intermediary structures would need the business to perform exceptionally well simply to recover the fee drag embedded in their entry point. The asset class rewards direct access and punishes delegated access through multiple layers of intermediation.

The throughline across all six categories, as Nathan framed it, was ownership of the flow directly. Each of these asset classes generates returns through mechanisms that operate independently of the public market cycle, and each can be structured to reduce or eliminate the counterparty layer. Taken together, they offer what the conventional portfolio does not: diversification not just in what you own, but in how ownership itself functions across the portfolio's constituent parts.

TBSO: Business Model, Financial Architecture, and the Public Markets Case

The structure of the TBSO business reflects a precise observation about where the gap in current financial services lies. Entrepreneurs build income. Investors deploy it.

In the conventional model of financial services, these are addressed by separate institutions serving separate market segments, but they describe the same person at different stages of a single journey: someone who is building a business today will eventually need to allocate the wealth that business creates.

TBSO is built on the premise that the same individual deserves coherent, integrated support across both phases of that trajectory, rather than the fragmented experience of navigating different institutions with separate mandates, separate incentives, and no shared view of the whole.

The project operates two product brands that correspond to the two sides of this journey.

SKL (skl.live) is the entrepreneur-facing platform:an AI-powered coaching and decision-support environment built around a community of hundreds of active members, access to more than 40 domain experts across 30 thematic areas, and daily live sessions covering the operational challenges of growing a business. TBSO reports that the platform recorded €2.4 million in billed subscription revenue in 2025, with approximately €2.3 million to be recognized as revenue in 2026.

Its technology foundation is OPENSKL, a proprietary agentic AI orchestration system that integrates across enterprise SaaS tools and provides a unified management interface for business operations. OPENSKL is currently deployed within SKL as an AI copilot; the broader platform, which will integrate and orchestrate all of an enterprise's systems through a single cockpit, is in development for wider deployment in 2027.

NVST (nvst.fr) addresses the investment side of the same journey: a multi-asset alternative investment platform covering private equity, music catalogs, crypto, and other alternative asset classes, built around a community focused on financial education and the kind of direct ownership philosophy that structured the evening's presentations.

TBSO reports that NVST recorded €3.6 million in billed subscriptions in 2025, with approximately €1.7 million to be recognized as revenue in 2026. The platform's full multi-asset interface, offering access to more than ten alternative asset classes through a single product rather than through the dispersed ecosystem of separate platforms that currently serves this market, is targeted for MVP launch in H1 2027.

TBSO is listed on Euronext Paris, where it operates as a publicly traded AI and fintech ecosystem.

The capital raise, structured as a public offering on Euronext Paris to fund the continued development of OPENSKL and the NVST multi-asset platform, closed 1.2x oversubscribed, with continuous trading opened since June 15. Full documentation is available at euronext.tbso.com.

A European Choice, Made on Principle

The decision to list on Euronext Paris rather than pursue a US exchange generated the most revealing exchange of the evening's Q&A. Éric did not frame the choice as a compromise imposed by circumstances, he framed it as a deliberate values alignment, made with full awareness of its financial consequences.

With Ledger, the hardware wallet company he co-founded and scaled to a multi-billion-dollar valuation, he had made the same choice. US capital markets would have valued the business at terms numerically superior. They would also have required a strategic orientation, a cultural gravity, and ultimately a form of alignment with US institutional capital that he was not willing to accept. Europe was the deliberate choice. His phrase for the financial consequence of that choice was precise and unhesitating: "It cost us billions." He said it without apparent regret, and the room understood that the constraint was self-imposed.

Nathan extended the argument to address a framing risk that TBSO's origin story creates. The company was originally announced as a Bitcoin treasury vehicle before the strategy was abandoned and the business pivoted to its two operating products mentioned above. That history nonetheless generates a gravitational pull in how investors might categorize the equity: the standard lens for Bitcoin-adjacent listed companies is mNAV, where the share price trades as a function of cryptocurrency holdings per share.

Nathan’s objection was precise: SKL and NVST are subscription businesses with their own operating economics, their own product roadmaps, and their own customer relationships. They deserve to be valued on those terms. Collapsing them into a cryptocurrency net asset value calculation is, in his view, a category error that misrepresents the investment thesis and structurally undervalues what has actually been built. A listed structure on Euronext, with proper financial reporting, continuous trading, and an active investor relations posture, creates the conditions for the market to understand and price the operating businesses on their own merits. That legibility was worth the valuation discount inherent in choosing a European listing.

Synthesis: The Path Toward Operational Resilience

The evening at Decentral House included something that financial conferences rarely manage: a demonstration of the thesis in the room itself. Chloe Ashton, Managing Director at 1275 SA, had arranged a tasting of three wines for the close of the session.

The name 1275 encodes a precise philosophy: 12 degrees Celsius and 75% humidity, the parameters under which investable wine must be stored to preserve both its character and its value. That specificity is the point. Fine wine is not uniformly investable; only a very narrow portion of global production holds and appreciates in value over time, and even within that portion, storage conditions determine whether the asset retains what makes it worth owning.

What the evening illustrated, across all of its components, is that the conversation about alternative assets has matured considerably. The question has moved from whether these asset classes are legitimate to how they work mechanically, what the ownership structures look like in practice, and how a sophisticated investor constructs a portfolio that is genuinely resilient rather than superficially diversified. These are precise, operational questions. They require practitioners who have done the work, not commentators who have read the prospectus.

Decentral House exists precisely to host these conversations: to create the conditions under which serious practitioners share frameworks and evidence with the community of entrepreneurs and investors who are prepared to act on them. What made June 8 worth attending was not the subject matter alone, but the quality of the people presenting it: founders who had built for decades at scale, lost money through institutional failure, and constructed a coherent worldview from both experiences. That combination of firsthand credibility and analytical rigor is what separates a genuinely useful conversation from a panel discussion.
