In a world where stress and anxiety often go unaddressed due to the high costs and stigma associated with therapy, Sonia emerges as a beacon of hope. Imagine having access to a supportive therapist anytime, anywhere, and at a fraction of the cost.

This is the vision that drives Sonia, an AI-powered cognitive behavioral therapist (CBT) that offers therapy sessions through a convenient app on your phone.

Founding story:

Sonia was founded in 2023 by three friends, Chris Aeberli, Dustin Klebe, and Lukas Wolf, who shared a background in computer science from ETH Zurich and AI research from MIT.

Their journey began during their graduate studies, where they realized the importance of mental health support but found traditional therapy inaccessible and expensive. (Source: Y Combinator)

Determined to make a change, they combined their expertise to create Sonia, named after the comforting voice that guides users through their therapy sessions.

Mission and approach:

One of the key challenges Sonia addresses is the accessibility of mental health care. With over 100 million Americans living in areas with limited access to therapists, traveling for hours for a therapy session is often not feasible.

Sonia breaks down these barriers by offering voice and text-based therapy sessions, allowing individuals to seek help from the comfort of their own homes or even on the go. (Source: Sonia Website)

Affordability and accessibility:

Moreover, Sonia's affordability is a game-changer. While traditional therapy sessions can cost upwards of $100 per session and involve long wait times, Sonia offers therapy for just 1% of the current costs, making it accessible to a wider population.

Whether it's a crisis at 2 am or the need for a quick emotional release after a tough day, Sonia is available 24/7, ensuring that support is always just a tap away. (Source: Y Combinator)

Range of interventions:

Sonia's commitment to making mental health care accessible to all is evident in their approach. The app offers various types of interventions, including structured CBT sessions and short, 5-minute sessions for quick emotional relief.

Users can choose the format that best suits their needs, whether it's a deep dive into cognitive restructuring or a moment of mindfulness to calm the mind. (Source: Y Combinator)


As Sonia continues to evolve, it remains rooted in its founders' philosophy: that everyone should have someone to lean on when they are willing to fall for something big and worthy.

By leveraging AI technology, Sonia is not just a therapy app; it's a lifeline for those seeking support in their mental health journey.
