In 1837, Thierry Hermès opened a harness and bridle workshop in Paris. He made equipment for horses. Nobody called it a luxury brand. There was no brand — just craft, applied to a problem, done well.

Nearly 190 years later, the company that bears his name posted €15.2 billion in revenue in 2024, crossed €16 billion for the first time in 2025, and briefly surpassed LVMH in April 2025 to become the most valuable luxury company on earth — market capitalisation of €243 billion — operating with a 41 percent operating margin. The highest in the luxury sector. By a significant margin.

The family still controls it. The leather goods are still made in France. The horse is still on the logo.

Every week in this series, I study one entity — a musician, a company, a family, an institution — that has built something genuinely durable. Something that has survived trend cycles, recessions, and the permanent temptation to compromise. I pull apart how they did it. I extract the principles. And then I apply them — because every rule that built a harness workshop into the world's most profitable luxury empire applies equally to your newsletter, your product, and your business.

I'm calling it The Hermès Code. Six principles. The same discipline as the Sade Code, applied to leather and silk across 189 years.

Before the principles, the data. Because the data is what makes Hermès worth studying.

In 2025, Hermès reported revenue of €16 billion — up 9 percent at constant exchange rates, and the first time the company has crossed that threshold. Recurring operating income of €6.6 billion, up 7 percent year-on-year. An operating margin of 41 percent — the highest in the luxury sector, held above 40 percent for the fourth consecutive year. Cash reserves of approximately €10 billion. Zero net debt.

Over four years — from 2021 to 2025 — Hermès has nearly doubled its revenue, from €9 billion to €16 billion, while holding its operating margin above 40 percent throughout. In most industries, aggressive growth compresses margins. At Hermès, the two have moved in lockstep.

That is not coincidence. That is the product of a deliberate, almost unchanging strategic posture.

Hermès never allows supply to catch demand.

The gap between what the market wants and what the company provides is not a problem to be solved — it is the source of pricing power, brand desire, and cultural cachet. Every other element of the strategy depends on this one holding.

The most visible expression of this is the Birkin bag. The story is well known: in 1984, actress Jane Birkin sat next to Hermès CEO Jean-Louis Dumas on a flight, complained she could not find a leather weekend bag she liked, and the resulting collaboration produced the Birkin. It was conceived as a functional object. It became something else entirely.

Birkin and Kelly bags rose 15 percent in resale value year-on-year through 2025. Hermès now holds a 138 percent value retention rate across its flagship handbag categories. A standard Birkin purchased at boutique retails between $10,000 and $40,000 — and resells for multiples of that. The bag has outperformed the S&P 500 over the past 35 years.

Hermès does not have a formal waiting list. It eliminated waitlists in 2010, replacing them with a system that rewards existing client relationships and purchase history. New customers cannot simply walk in and buy a Birkin. The product is allocated, not sold. That distinction is everything.

The company is aggressively expanding its workshop capacity — 25 leather ateliers as of 2025, with three more planned through 2027 and a new site confirmed for 2030. It refuses to allow supply to catch up to demand. The gap is the product.

The lesson: scarcity is not a problem — it is a strategy. Make less than the market wants, and the market will always want more.

Hermès sells exclusively through its own stores and its own website. It has never licensed its brand to third-party manufacturers. It does not operate outlet stores. It does not participate in promotional sale events. It has no wholesale exposure to department stores or multi-brand retailers.

This is a meaningful sacrifice. Licensing the Hermès name — the way many luxury brands do — would generate substantial short-term revenue. The brand has enough recognition to command licensing fees across categories: fragrances, accessories, eyewear, homewares. Hermès said no to all of it.

The reason is simple: licensing transfers control. Once another company manufactures a product under your name, you no longer fully control the quality, the presentation, or the context in which that product appears. One badly positioned licensed product dilutes the entire brand. Hermès cannot afford dilution — dilution would destroy the very thing that makes the brand worth licensing in the first place.

Full-price sell-through is not an aspiration at Hermès. It is a rule. The company's disciplined distribution strategy meant it preserved full-price demand even when the broader luxury market normalised in 2024 and 2025. Competitors faced rising inventory concerns. Hermès had nothing left over.

The lesson: own the distribution. The moment you hand it to a third party, you hand them power over your brand, your pricing, and your customer relationship.

Most luxury companies outsource significant portions of their production. Hermès does not.

The company operates what it calls a vertically integrated artisanal model. One hundred percent of Hermès leather goods are made in France. Approximately 55 percent of all products — across all 16 categories — are made in the company's own exclusive workshops. Seventy-five percent are made in France overall.

Hermès trains more than 400 artisans per year through its own schools — the Écoles des savoir-faire. It added more than 1,300 employees in 2025, 800 of them in France. It opened its 24th leather atelier in 2025 and confirmed new sites through 2030.

CEO Axel Dumas has explained the logic: "If we launch a new leather workshop, it takes five years to open one. And if we launch a project in such an unstable world, it is because we are responding to a demand that shows no sign of falling."

By controlling production, Hermès controls quality. By controlling quality, it controls the brand. By controlling the brand, it controls pricing. Every link in that chain depends on the one before it.

The model also functions as a competitive moat that cannot be acquired. The savoir-faire — the knowledge, the technique, the culture — accumulates over generations. Competitors cannot simply buy their way into it. LVMH, with all its resources, cannot replicate what 189 years of artisanal continuity produces. The moat is time itself.

The lesson: whatever is at the core of your product or service — the thing that makes it yours — keep it in-house. Outsourcing the core is outsourcing the moat.

In 2010, Bernard Arnault — head of LVMH, the world's largest luxury conglomerate — disclosed that LVMH had quietly accumulated a 17.1 percent stake in Hermès through equity derivatives, without triggering regulatory disclosure requirements. The move was widely understood as a precursor to a hostile takeover bid. The luxury world was stunned.

Hermès was not.

The family responded by consolidating its shares into a holding company, H51, which controls more than 54 percent of shares and is bound by a 20-year lockup agreement. Family members who were previously individual shareholders became collective shareholders, making it structurally impossible for any outsider to acquire a controlling position. LVMH, under regulatory pressure from French authorities, disposed of its Hermès stake by 2014. Family ownership was restored above 67 percent by the end of 2022.

Dumas has reflected on it directly: "When LVMH aimed to take control of Hermès, I fought to guarantee its independence because I believed in the Hermès model. I am happy to say to those who listened to me that it was not a bad deal."

Family ownership insulates the company from quarterly earnings pressure. Decisions are made over five-year and ten-year horizons. Dumas can open a new atelier that will take five years to reach full productivity because he does not answer to a shareholder base demanding results next quarter.

Independence is not sentiment here. It is the structural precondition for every other principle on this list.

The lesson: long-term decisions require long-term ownership structures. If you answer to quarterly pressure, you will make quarterly decisions. The best long-term choices are almost always short-term sacrifices.

Hermès operates across sixteen business lines — what the company calls métiers: leather goods, silk, ready-to-wear, watches, jewellery, perfume, homewares, equestrian equipment, and more. Every category maintains the same aesthetic and quality commitments.

The brand does not chase category trends. It extends its identity into new categories, not the other way around. When Hermès enters a new product area, it does so on its own terms — with the same materials standard, the same craft standard, the same refusal to compromise on finish. A Hermès silk scarf and a Hermès saddle and a Hermès watch all feel, unmistakably, like Hermès objects. The brand is the signal. The product is the carrier.

This coherence runs all the way back to 1837. The aesthetic DNA of Hermès — precision, function elevated to beauty, respect for materials — was present in Thierry Hermès's harness workshop. It is present in the Birkin. It will be present in whatever Hermès makes in 2050.

That kind of coherence cannot be manufactured. It can only be protected — by refusing, generation after generation, to allow short-term opportunity to override long-term identity.

The lesson: every time you say no to the off-brand opportunity — the inconsistent collaboration, the quick-revenue licensing deal — you add to the credibility of the brand. That credibility is worth more than any single deal.

Hermès has not grown through acquisition. No bolt-on brands. No conglomerate roll-ups. No acquiring a competitor to gain market share. Every new capability — from equestrian equipment to perfumery — was developed internally, slowly, and only when the company was confident it could maintain the quality standard the brand demands.

This is a striking choice in the context of the luxury sector, which is increasingly dominated by conglomerates. LVMH owns more than 75 brands. Kering owns Gucci, Saint Laurent, Bottega Veneta, Balenciaga, and more. Hermès looked at that model and declined.

The reason is the same as with licensing. Every acquisition introduces a variable. A different culture, a different quality standard, a different history. Integrating that variable risks the coherence of the whole. For a brand whose entire value proposition rests on the integrity of every product it makes, one cultural compromise can undermine the credibility of everything else.

Better to grow slowly, from within, and control the quality absolutely, than to grow quickly through acquisition and risk the thing the brand actually sells: trust.

The lesson: acquisition is seductive and dilutive. Internal growth is slow and pure. Hermès has chosen slow and pure for 189 years.

Strip away the mythology and what remains is a strategy that is, in principle, simple. In practice, it is extraordinarily difficult to execute consistently — because it requires refusing things that look like opportunities.

Control supply: do not allow what you make to be everywhere. Make less than the market wants, and the market will always want more.

Own the distribution: sell through your own channels. The moment you hand distribution to a third party, you hand them power over your brand, your pricing, and your customer relationship.

Make it, do not outsource it: whatever is at the core of your product — the thing that makes it yours — keep it in-house. Outsourcing the core is outsourcing the moat.

Protect independence: long-term decisions require long-term ownership structures. If you answer to quarterly pressure, you will make quarterly decisions.

Hold the identity: coherence compounds. Every time you maintain your standard — every time you say no to the off-brand opportunity — you add to the credibility of the brand.

Grow from within: acquisition is seductive and dilutive. Internal growth is slow and pure. Hermès has chosen slow and pure for 189 years. The result is a company that cannot be easily replicated, acquired, or disrupted — because its moat is the accumulated result of thousands of individual refusals.

Hermès surpassed LVMH to become the most valuable luxury company on earth in April 2025. Then it continued growing. It crossed €16 billion in revenue for the first time. Its margin held above 40 percent. New ateliers opened. New artisans trained. The family retained control.

In an industry defined by aspiration, Hermès has achieved something rarer: it has made the aspiration outlast every trend, every recession, every acquisition attempt, and every competitor who has tried to replicate it.

That is what 189 years of refusals looks like.
