It’s well known that loneliness is increasing worldwide, but according to recent figures by the US Surgeon General, loneliness is as dangerous to health as smoking. We are living through a loneliness epidemic:
- A 2024 poll by the American Psychiatric Association found that 30% of U.S. adults have felt lonely at least once a week in the past year, with 10% reporting daily loneliness.
- The 2025 Pew Research Center survey highlights that one in six Americans feel lonely or isolated from those around them all or most of the time.
- 61% of people aged 18 to 25 report feeling “seriously lonely”.
- A quarter of Americans say they don’t have a single person they can confide in.
- Social isolation significantly increases the risk of premature death and is as harmful as smoking 15 cigarettes a day.
While technology is partly responsible for this decline in real-world friendships, it also offers a path forward for companionship. From AI girlfriends and boyfriends, online therapists, Our relationships are already largely digital, priming us for the age of companion AIs. Many meaningful friendships and romantic connections now take place entirely online, unbounded by geography.
A study published by Harvard Business Review in April 2025 confirmed that indeed AI companionship and therapy are now the number one use case of generative AI.
At Remagine Ventures, we’re investing in the technologies driving how consumers spend their time and money. Looking at the strong engagement in the AI companionship category we wanted to share the existing trends and were we see opportunities for startups.
From Niche to Mainstream: The Rapid Adoption
While AI companion apps don’t quite reach the levels of adoption of general AI assistants (Character AI has 10% of ChatGPT in terms of unique users), they significantly outperform general chatbots in terms of engagement.
According to figures published by WndrCo in April 2025, the average Character AI user has 25 sessions per day, spending about 1.5 hours daily in-app. The demographics reveal an even more compelling story. Of Character AI’s 233 million users, a majority (57%) are aged 18–24, and studies show that 80% of Gen Z would be open to marrying an AI. This generation, despite growing up more digitally connected than any before, also reports the highest levels of loneliness—making them the trailblazers of a new kind of relationship.
This exceptional engagement stems from the apps’ ability to fulfill basic psychological needs—to be heard, to converse freely, and to receive non-judgmental attention—needs that have grown more acute as traditional social connections have weakened across societies

There’s a growing number of AI companion apps, but the landscape is still relatively small:
While it’s already 1 year old, I also recommend this landscape map and thesis by A16Z:
What might have once felt “icky” is rapidly becoming commonplace. Companies like Replika, Snapchat’s My AI, and Xiaoice boast hundreds of millions of users:
- Snapchat’s My AI has over 150 million users who sent more than 10 billion messages in its first two months. This chatbot avoids romantic or NSFW topics, focusing on light-hearted entertainment.
- Replika has an estimated 25 million users.
- The term AI girlfriend has risen by 2,400% in the past2 years according to Google Trends
- Public interest is surging, with estimates suggesting over 70,000 monthly online searches for AI romantic partners and a dramatic rise in companion app downloads.
- A recent study found that almost one in five US adults (19%) have chatted with an AI system designed to simulate a romantic partner. This rate is even higher among young adults (18-30), with nearly one in three young adult men (31%) and one in four young adult women (23%) reporting such interactions.
These systems leverage LLMs and advanced natural language processing to create impromptu, free-flowing conversations that can sound indistinguishable from humans. They continuously learn from interactions, developing relationship “personas” that customize interactions to user preferences and create increasingly sophisticated simulated emotional connections. They are often designed to be emotionally validating, caring, and constantly interested in the user.
Diverse Use Cases Beyond Romance
While romantic applications are an early driver (and often the first consumer use case for new technologies, as the adult entertainment industry has often been at the driving edge of new tech), the potential of AI companions extends far wider. I agree with Hugo Amsellem’s view that AI has the potential to completely change the paradigm on social, travel, dating, education, etc, moving a way from a read-only feed into a more interactive, AI companion experience.
Here are a few use cases in that vain:
- General Friendship: Apps like Tolan provide “alien friends” for chatting, especially resonating with autistic, neurodivergent, or socially anxious users. For many, an attentive digital friend is preferable to social isolation.
- Mental Health: AI chatbots are showing demonstrable benefits. A Dartmouth study on “Therabot” found a 51% drop in depressive symptoms, 31% drop in anxiety, and 19% drop in body image concerns for eating disorder patients, with results comparable to gold-standard cognitive therapy. This addresses a significant access problem in mental healthcare. Some studies also indicate positive mental health impacts, including reduced depression and anxiety in users of AI companions.
- Grief and Legacy: Technologies already exist (e.g., HereAfter.ai) that allow users to chat with interactive avatars of deceased relatives, offering a compelling way to navigate grief or preserve someone’s legacy.
- Relationship Coaching: Users are already leveraging AI for relationship advice, with AI providing a non-judgmental ear for “trauma-dumping” or even nudging users to be “better” human friends.
- Kids + Learning: AI companions embedded in plush toys (e.g., Curio) offer a screen-free way for children to interact and learn. OpenAI has partnered with Mattel to explore IP agreements for popular characters like Barbie, potentially leading to interactive AI toys.
- Seniors: With 1 in 4 adults over 65 socially isolated, AI companions can provide engaging conversation, remember family names, and even prompt medication reminders. Companies like Zoog (disclaimer: Remagine Ventures is an investor) are offering grandparents ways to interact with their families using creative storytelling.
AI companions might become a new social layer, on top of major consumer use cases, like a friend/expert you can consult with while shopping, booking travel, dating or even while making big professional decisions.
Navigating the Nuances: Risks and Ethical Considerations
It’s important to mention that the rapid rise in AI companionship also has its risks and potential downsides. A mother of a 14 year old who tragically took his own life is suing Character ai that failed to introduce proper safety measures. There are examples of unethical companions, Replika has been hit an FTC complaint and so on.
The rapid adoption of AI companions is outpacing public discourse, raising critical questions:
- Privacy and Data Security: These platforms collect vast amounts of intimate user data, necessitating robust security measures and transparent practices. Many small startups currently lack minimum security standards, leading to potential security breaches.
- Dependency and Mental Health: While initial studies show positive short-term mental health impacts, concerns exist regarding emotional dependency and the erosion of human relational skills. The use of AI companion apps is strongly linked to a higher risk of depression and higher reported levels of loneliness. The causal link between AI use and social isolation is still being studied, with mixed evidence, though some users have reported improved social skills in human interactions after engaging with AI companions.
- Unrealistic Expectations & Societal Cohesion: AI companions are designed to be non-judgmental and sycophantic, always agreeable. This could hinder personal growth and, if widespread, potentially undermine societal cohesion by reinforcing individual opinions and biases, akin to social media “echo chambers”. This raises concerns about users preferring AI communication over engaging with real people, with 21% of users preferring AI communication and 42% finding AI programs easier to talk to.
- Extreme Cases: Tragic incidents, such as a would-be assassin allegedly encouraged by Replika or a Belgian man’s suicide linked to a chatbot, highlight the potential for severe harm when users lose touch with reality or are unchecked in their thoughts.
These concerns are serious, but for many, AI companions fill a void that real-world connections cannot or do not. The optimist’s view is that AI friends shouldn’t replace human connection but supplement it where it’s missing, making people feel noticed, cared for, and soothed – a net positive.
AI Companions are here to stay
The rise of AI companions signifies a seismic shift in human-computer interaction. We are entering a new “companion economy” that will span entertainment, utility, and deeply personal connections. While guardrails and continued research are crucial, the demand for meaningful connection in an increasingly isolated world makes AI companions an undeniable force.
We’re just at the beginning of this journey. The tools available today will seem rudimentary in a few years compared to the depth and complexity of future relationships. We anticipate innovations in:
- Multi-modal companions (live phone/video calls with avatars, AI avatars that travel with users in AR/VR headsets).
- AI adaptations of real people (influencers, experts, even personal AI clones for everyone).
- Incorporation into human interactions (AI relationship coaches in group chats, AI characters in virtual communities).
The market for AI companions is ripe for innovation and investment. We believe the biggest wins in consumer AI will emerge from this space, transforming how we connect, learn, and live.
