Alison Darcy is an Irish research psychologist and technologist. She is the founder and president of Woebot Health, a company that developed digital therapeutics and behavioral health products, including an AI-powered chatbot for mental health support. Darcy's work sits at the intersection of clinical psychology and artificial intelligence, and she has been recognized for her contributions to the field, notably through her inclusion in the TIME100 AI list in 2023.
Darcy's career spans academia, technology, and entrepreneurship. She trained as a clinical psychologist, conducted postdoctoral research at Stanford University, and later founded Woebot Health in 2017. Her work has focused on making evidence-based mental health interventions, particularly cognitive behavioral therapy (CBT), more accessible through scalable digital tools.
Early Life and Education
Darcy grew up in Ireland and pursued undergraduate studies in psychology at University College Dublin. After completing her degree, she developed an interest in computer science and moved to London, where she worked as a software developer at an investment bank. During the dot-com crash, the bank was acquired by a larger financial institution, prompting Darcy to reconsider her career path. She sought to combine her technical skills with her background in psychology, and she began working with a charity that supported people with eating disorders.
Darcy identified a gap in online mental health support, particularly for individuals in rural communities who had limited access to care. Collaborating with a colleague from her software development days, she built an online support network that provided round-the-clock assistance to people in need. This early experience sparked her interest in using technology to deliver mental health services.
Darcy eventually returned to University College Dublin for graduate studies, completing a doctoral research program in clinical psychology. Her doctoral research examined the effectiveness of group cognitive behavioral therapy. After a year in London, she moved to the United States, where she joined Stanford University as a postdoctoral researcher in clinical psychology. At Stanford, she collaborated with Andrew Ng, a prominent figure in machine learning, and became interested in whether artificial intelligence could meaningfully support people with mental health conditions.
During her clinical practice, Darcy grew concerned about the lack of continuity between inpatient care and the transition back to everyday life. This concern, combined with her interest in AI, laid the groundwork for her later entrepreneurial work.
Research and Career
Darcy continued to research eating disorders, with a particular focus on anorexia nervosa. She observed that few clinicians had adequate training to treat patients with this condition, and she pioneered the use of online learning methods to train clinicians. However, she became increasingly convinced that to effectively combine technology and psychology, she would need to work outside academia. This realization led her to leave Stanford and start her own company.
In 2017, Darcy founded Woebot Health, a company that developed an AI-powered chatbot designed to help users monitor their moods and manage their mental health. Woebot is a dynamic, individualized tool that allows patients to forge a therapeutic connection. It maintains the scalability and agency of self-help techniques while enhancing, rather than replacing, human healthcare providers. The chatbot delivers cognitive behavioral therapy techniques through conversational interactions, and it has been shown in clinical trials to reduce symptoms of anxiety and depression within two weeks.
The board of Woebot Health is chaired by Andrew Ng, reflecting the company's deep ties to the AI community. Darcy's vision was to make mental health services and CBT training accessible to all, regardless of geographic or economic barriers.
In April 2020, Woebot added COVID-19 support, expanding its CBT-based offerings to include interpersonal psychotherapy. This addition was particularly timely given the global mental health challenges posed by the pandemic. Subsequent research suggested that Woebot could reduce depression and anxiety symptoms in as little as two weeks.
By 2023, Woebot Health had raised $123.5 million and served over 1 million users. In the fall of 2023, Darcy was named to the TIME100 AI List, which highlights individuals who have made significant and impactful advancements in artificial intelligence.
In late June 2025, Darcy decided to shut down Woebot's therapy chatbot due to regulatory challenges. The bot struggled to keep pace with the rapid rate of technological advancement in the AI space. Despite this setback, Darcy has continued to contribute to the field through writing and teaching. She serves as a lecturer at Stanford University and has authored numerous publications discussing the intersection of AI and mental health.
Contributions to AI and Mental Health
Darcy's work is notable for its early integration of artificial intelligence into mental health care. At a time when online mental health support was scarce, she recognized the potential of AI to provide scalable, evidence-based interventions. Her research demonstrated that a fully automated conversational agent could deliver CBT effectively, a finding that has influenced subsequent developments in digital therapeutics.
Darcy's approach emphasized the importance of safety and efficacy in AI-driven healthcare. She advocated for rigorous clinical validation of digital tools, ensuring that they meet the same standards as traditional therapies. Her work has also highlighted the potential of AI to address disparities in mental health care access, particularly for rural and underserved populations.
The shutdown of Woebot's chatbot in 2025 underscored the challenges of navigating regulatory frameworks in the rapidly evolving AI landscape. However, Darcy's broader contributions to the field, including her publications and teaching, continue to shape the conversation around AI and mental health.
Selected Publications
Darcy has co-authored several influential papers. Notable among them:
- Fitzpatrick, Kathleen Kara; Darcy, Alison; Vierhile, Molly (2017). "Delivering Cognitive Behavior Therapy to Young Adults With Symptoms of Depression and Anxiety Using a Fully Automated Conversational Agent (Woebot): A Randomized Controlled Trial". JMIR Mental Health.
- Darcy, Alison M.; Louie, Alan K.; Roberts, Laura Weiss (2016). "Machine Learning and the Profession of Medicine". JAMA.
- Aspen, Vandana; Darcy, Alison M.; Lock, James (2013). "A review of attention biases in women with eating disorders". Cognition and Emotion.
These publications reflect Darcy's dual expertise in psychology and technology, and they have been widely cited in the fields of digital health and AI.
Awards and Recognition
Darcy's work has earned her recognition beyond the TIME100 AI List. Her inclusion in that list in 2023 highlighted her as a leader in the application of AI to mental health. She has also been a sought-after speaker and lecturer, sharing her insights on the responsible development of AI in healthcare.
Legacy and Impact
Darcy's legacy lies in her pioneering efforts to bring AI into mental health care. While the Woebot chatbot was discontinued, the company's research and products have informed a generation of digital therapeutics. Darcy's emphasis on clinical validation and user-centered design has set a standard for AI-driven health interventions. Her work continues to inspire researchers and entrepreneurs who seek to harness technology for social good.
Darcy's career also illustrates the importance of interdisciplinary approaches, combining psychology, computer science, and entrepreneurship. Her journey from a psychology student in Dublin to a leader in AI-driven mental health underscores the potential for innovation at the intersection of fields.
