Alison Darcy

Alison Darcy is a research psychologist and technologist. She is the Founder and President of Woebot Health, a company which provides digital therapeutics and behavioural health products.

Early life and education Darcy was an undergraduate student in Ireland at the University College Dublin, where she specialised in psychology. After completing her studies, Darcy became interested in computer science, so moved to London to work in an investment bank as a software developer. In 2023, Darcy was named to the TIME100 AI List for her impactful work combining artificial intelligence and mental health through her company, Woebot Health. The investment bank was acquired by a larger bank during the dot com crash, leaving Darcy looking for new options. In particular, she was interested in combining her skills in technology with her talent for psychology, and worked with a charity to support people with eating disorders. At the time there was very little online support for people with mental health conditions, and accessing care was particularly difficult for people in rural communities. Working with one of her colleagues in software development, Darcy built an online support network, providing round-the-clock support to people who needed to talk. After a year in London, Darcy moved to the United States, where she joined Stanford University as a postdoctoral researcher in clinical psychology. At Stanford, she collaborated with Andrew Ng, and became interested in whether artificial intelligence can meaningfully help people with mental health conditions. In her clinical practise, Darcy was increasingly concerned that there was no continuity between leaving in patient care and entering the real world. an artificial intelligence powered chatbot that helps users monitor their moods and manage their mental health. More specifically, Woebot is a dynamic and individualized instrument via which patients can forge a therapeutic connection. It maintains the scalability and agency that define self-help techniques while enhancing (rather than replacing) human healthcare providers and unlocking the therapeutic power associated with guiding. This AI acts like an automatic therapist that has been found to reduce symptoms of anxiety and depression in two weeks. The board of Woebot is chaired by Ng.

In April 2020, Woebot added COVID-19 support, expanding its CBT support to include interpersonal psychotherapy. Following that additional support, Woebot has been suspected to reduce depression and anxiety symptoms within as little as the passage of two weeks. In the fall of 2023, Darcy was added to the 2023 Time100 AI List, which aims to highlight individuals that have made significant and impactful artificial intelligence advancements. By 2023, $123.5 million had already been made by Woebot, which already had over 1 million users. In late June 2025, Darcy decided to shut down Woebot's therapy chatbot due to regulatory challenges. The bot was unable to keep up with the rate of technological advancement in the AI space. While Darcy did decide to shut the chatbot down, she has found more ways to give back to the field. She has written many books when discussing the field, and she serves as a lecturer at Stanford University
