The most human of all emotions has become the most profitable. And the people selling you the cure are the ones who made you sick.
There is a man in Tokyo you can rent for the afternoon.
He is called an ossan — literally, a middle-aged man. He will walk with you through a park. He will listen. He will not judge you, rush you, or check his phone. When the hour is up, you pay him and you both go home. No strings. No follow-up. Just company, invoiced and delivered.
To a previous generation, this would have read like satire. To ours, it reads like a business opportunity. And that distinction between those two readings is perhaps the most quietly devastating thing about the world we have built.
Loneliness, for all of recorded human history, was a wound. Today, it is a market.
The Numbers That Should Keep Us Up at Night
Let us start with the scale of what we are dealing with, because the numbers have a way of making the abstract suddenly, viscerally real.
The World Health Organization, in a 2025 analysis, estimated that nearly one in six people globally experienced loneliness between 2014 and 2023 and linked that isolation to significant health risks and hundreds of thousands of deaths annually. The US Surgeon General, in a landmark 2023 advisory, did not merely call loneliness a social problem. He called it an epidemic and stated that its health consequences are comparable to smoking fifteen cigarettes a day.
Fifteen cigarettes. Every day. Just from being alone.
Cigna’s research, tracking American loneliness across multiple years, found the figure hit 61% in 2019. It has barely moved since. Among Gen Z — the generation that grew up with a supercomputer in their pocket and a social network in their palm — the rate climbs to 67% in the most recent surveys, making the most digitally connected generation in history also the loneliest. The OECD, in a 2025 report spanning 38 member countries, found that 8% of adults had no close friends at all. Not a few friends. None.
The generation that grew up with more ways to communicate than any in history is, by every measurable indicator, the loneliest generation ever recorded.
Enter the Entrepreneurs
Here is where the story takes its turn away from tragedy and toward something colder and more instructive.
In 2018, the United Kingdom did something no government had ever done before. It appointed a Minister for Loneliness a cabinet-level acknowledgment that isolation had become a genuine public health emergency. Prime Minister Theresa May gave the role to Tracey Crouch, a junior minister, with a mandate to build a government-wide strategy. It was a serious, sobering moment. Governments were beginning to understand the problem.
Venture capitalists understood it differently. They saw a gap in the market.
What followed has been one of the most remarkable quiet expansions in the history of consumer capitalism. The AI companion market apps and platforms that offer users a simulated relationship with an artificial intelligence was valued at approximately $28 billion in 2024. Analysts project it will reach somewhere in the region of $550 billion by 2035. To place that in context: the entire global video game industry was worth roughly $187 billion in 2024. We are building an industry nearly triple the size of gaming — out of loneliness.
Replika, one of the most prominent AI companion apps, has accumulated over ten million active users. People do not merely use it the way they use a weather app or a calculator. They name their companions. They confide in them. Some describe them as their closest relationship. Harvard Business School researchers who studied Replika users found that participants were measurably lonelier than average and felt a genuine sense of social support from the app. The product works, in the narrow sense that it makes people feel less alone in the short term. What it does to them in the long term is a question the industry would rather not study too closely, because the business model depends on people returning, not recovering.
The Architecture of Profitable Loneliness
To understand how we arrived here, you have to understand that loneliness was not simply discovered by the market. In important ways, it was manufactured by it.
The traditional structures of human community, the neighbourhood, the religious congregation, the extended family, and the third place have been quietly dismantled over the past fifty years, often by the very forces of convenience and individualisation that technology promised us. Remote work eliminated the accidental daily human contact of the office. Social media replaced the messy, reciprocal labour of friendship with the frictionless consumption of other people’s curated highlights. Urbanisation packed more people into smaller spaces and made them more strangers to each other than any rural community had ever managed. Streaming gave us the ability to never be bored alone and in doing so, removed the discomfort that might have pushed us toward other people.
We did not notice the cost, because each individual trade-off seemed reasonable. Why commute when you can work from home? Why call when you can text? Why go out when everything you want can arrive at your door in forty minutes?
And then, somewhere in the accumulated arithmetic of all those reasonable choices, we looked up and found ourselves alone.
The market noticed this before any of us did. Because what the market is extraordinarily good at is identifying unmet need and what it found, lurking beneath the convenience economy, was an ocean of unmet human need for connection. The loneliness economy did not create the wound. It simply arrived, swiftly and efficiently, with a product to sell into it.
What They Are Actually Selling You
Walk through the loneliness economy and you will find it is not a single industry. It is a layered system of solutions, each one targeting a different depth of the same void.
At the surface level, there are the dating apps, the most visible face of monetised loneliness, platforms that charge you for the chance to find connection while being deliberately engineered to keep you searching rather than finding. Then come the parasocial economy’s products: OnlyFans, Cameo, Patreon platforms where you pay for the feeling of a relationship with someone who does not know you exist. This sector has seen explosive growth since 2020, driven entirely by people seeking the sensation of being seen and known. Go deeper and you find the wellness economy: therapy apps, mindfulness subscriptions, emotional support platforms, digital mental health services that charge monthly fees to manage feelings that, in previous generations, would have been processed inside a community that was available for free. Go deeper still and you find the AI companion layer the Replikas and Character.AIs, the apps that simulate genuine relationships with algorithmic precision.
And beneath all of it, running quietly through every transaction, is the same implicit promise: you do not have to do the hard work of being known by another person. We will sell you something that feels close enough.
In Tokyo, restaurants now feature solo dining booths, elegant, private, designed for one so that people who eat alone do not have to feel the discomfort of eating alone in public. In Seoul, similar spaces are proliferating. In India, coworking chains have begun selling not desk space but community membership. The value proposition is not the Wi-Fi. It is the sense of belonging. Someone has looked at human beings who feel untethered and thought: I can charge a subscription for that.
The Ethical Problem Nobody Wants to Name
Here is what separates loneliness from other markets. When a pharmaceutical company sells you a painkiller, the ethical obligation is relatively simple: treat the pain, disclose the risks, do not create dependency. When a loneliness business sells you a companion app, the ethical obligation is far more complicated because the product works best when you keep needing it.
An app that genuinely solves loneliness would teach you how to build real relationships, help you develop the social confidence you lack, connect you with actual people and then lose you as a customer. That is not a viable business model. So instead, most of these platforms are optimised for engagement, not for healing. They are designed to be the destination, not the bridge to somewhere better.
Social scientists who study loneliness have been consistent on this point. Julianne Holt-Lunstad, one of the world’s leading researchers on social isolation and health, has long argued that chronic loneliness carries physical health risks on par with major chronic disease and that the interventions that actually work are ones that buildgenuine human connection, not ones that substitute for it. An AI that makes you feel heard does not give you the thing your body and mind are actually craving. It gives you the neurological shadow of it just convincing enough to reduce the urgency of seeking the real thing.
That is the darkest reading of the loneliness economy. Not that it is cynical plenty of the people building these products genuinely believe they are helping. But that it is structurally incapable of solving the problem it profits from. Every subscription renewed is, in some sense, a loneliness that persists.
The Deeper Question
Japan has led the world in deploying robot companions for its ageing population from Paro, a therapeutic robot shaped like a baby harp seal that responds to touch and provides measurable comfort to isolated patients, to humanoid companions that chat, dance, and recognise emotions. Japan’s government has actively subsidised these technologies for over a decade, driven by a crisis it can no longer ignore: the phenomenon the Japanese call kodokushi, the lonely death, where elderly people die alone and are not discovered for days, weeks, or in the most harrowing cases, months. In 2024 alone, more than 76,000 people died alone in Japan. That is roughly 208 solitary deaths every single day.
Japan is not an outlier. It is a preview.
Every society that has pursued maximum economic efficiency, maximum individual freedom, and maximum technological convenience has ended up here staring at a loneliness epidemic and trying to engineer its way out of a problem that engineering helped create. The United States leads the world in individual liberty and in loneliness statistics simultaneously. That is not a coincidence. It is a consequence.
What we have lost is the neighbourhood, the congregation, the third place, the slow unremarkable dailyity of being known by the people around you cannot be recovered through a subscription. It cannot be rebuilt by an app. It requires the one thing the loneliness economy is not selling and cannot sell: the willingness to be inconvenient for each other, to show up without being scheduled, to be present without being productive.
That is not a market. That is a civilisation.
There is nothing inherently wrong with building businesses that address human needs. The loneliness economy, at its best, offers genuine lifelines to people who have none, the elderly, the disabled, those in crisis at two in the morning with no one to call. These services matter. These services save lives.
But we should be honest about what we are doing when we allow loneliness to become a business model. We are accepting, implicitly, that the conditions which produce loneliness are permanent that isolation is an infrastructure problem to be managed, not a social failure to be corrected. We are paying companies to make solitude more comfortable, and in doing so, we are making it more acceptable. We are buying relief when what we need changes.
The loneliness economy will keep growing. The projections are unambiguous and the demand is vast and the venture capital is flowing. Somewhere right now, an engineer is building a better AI companion. A founder is pitching a new community membership product. An investor is approving a round of funding for an app that promises to make loneliness feel a little less like loneliness.
And somewhere else, a man in Tokyo is walking through a park with a stranger he is being paid to listen to.
Both of them are lonely. Only one of them is being paid for it.
The most sophisticated societies in human history are paying algorithms to remember their birthdays. That should tell us everything about where we went wrong.
