Between 2023 and now, loneliness stopped being treated as a personal problem and turned into a market. Not a metaphor, an actual market, with revenue projections, competing companies, and the same growth incentives you would find in any other tech sector. Understanding how that happened tells you something important about where AI products are headed next.

The numbers alone are startling. There are now over 128 AI companion apps in active distribution, up from just 16 three years ago, and the global market is projected to grow from roughly 49 billion dollars in 2026 to 552 billion dollars by 2035. With one in six people worldwide reporting loneliness according to the World Health Organisation, this has become one of the fastest-growing sectors in technology, and one of the most ethically complicated. 

The players are already familiar to anyone who has spent time online. Replika pioneered the space years ago and remains built around long-term emotional connection, with a memory system, mood tracking, and journaling designed to help users manage loneliness over time. Character. AI took a different path, leaning into roleplay and community-created characters, with more than twenty million characters built by users rather than the company itself. Newer entrants like Pi, Nomi, and Candy AI have carved out their own niches, from free casual conversation to more relationship-focused products. 

Who is actually using these apps might surprise you. Emotional support is the most cited reason people give, with forty per cent of users identifying as having mental health challenges, followed by entertainment and roleplay at thirty-five per cent, and loneliness or social connection specifically at thirty per cent. These are not fringe numbers. This is a mainstream behaviour now, and the embarrassment that used to surround it has faded fast. 

Here’s what deserves real scrutiny. Dating apps have long faced criticism for profiting when users keep coming back rather than when they find a lasting relationship. AI companions have arguably built something worse. The longer someone talks to an AI companion, the more they engage, the more likely they are to renew a subscription, meaning the company's incentive is built directly on deepening emotional attachment rather than resolving it. Researchers have started calling this dynamic intimacy capitalism, a term for business models that profit specifically from keeping people dependent on a paid substitute for real human connection. 

This is not a hypothetical concern anymore. Character.AI and Google have already reached settlements over lawsuits tied to teen mental health harms and suicides, and Replika faced a five million euro fine over GDPR violations. Lawmakers have taken notice too, with senators demanding information directly from AI companion companies. These are the kinds of consequences that usually arrive after a technology has already scaled past the point where anyone can easily rein it in. 

So what should someone actually do with this information? If you are a student or young professional who finds yourself reaching for one of these apps during a rough week, that is not something to feel ashamed about; plenty of research shows short-term relief is real. But it is worth treating these tools the way you would treat any product built to maximise your time inside it. Notice how you feel after using it, not just during. If you are a founder or product person building in this space, the uncomfortable question worth asking yourself is whether your product is designed to help people need it less over time, or more.

The loneliness economy is not going away. If anything, as AI models get better at sounding warm and remembering details about your life, the pull will only get stronger. The technology itself is not the problem. The problem is a business model where a company's revenue grows in direct proportion to how emotionally dependent you become, and very few of these apps have found a way around that structural pull yet.
