Company profile
researched Sep 2026Affiniti AI is a conversational AI company serving the mental health and wellbeing sector. Its offering consists of two components: the Affiniti Platform, used by therapists, and the Affiniti Co-Therapist, a client-facing tool that provides AI-based therapeutic support between scheduled sessions. The company positions the product as an augmentation of talking therapy rather than a substitute for clinicians, stating that the Co-Therapist operates under the direction of a qualified therapist and helps clients rehearse and internalise coping strategies learned in session.
For therapists, the platform offers analysis of client interactions and pre-session insights intended to inform session planning, along with the ability to assign specific evidence-based exercises such as cognitive restructuring or worry management. The system supports a range of psychotherapy approaches with particular emphasis on Cognitive Behavioural Therapy. The company states that it applies encryption to data in transit and at rest and that the platform is designed for compliance with applicable healthcare and data protection requirements. The UK registered entity, AFFINITI AI LIMITED, was incorporated on 20 March 2020 and files under SIC codes for software development, IT consultancy, and data processing and hosting.
Business model
Affiniti AI sells a software platform to therapists and mental health practices, who in turn assign the Affiniti Co-Therapist tool to their clients for use between sessions. The website's primary conversion routes are a demo booking and a sign-up flow, indicating a direct commercial motion aimed at practitioners rather than a purely consumer product.
Traction
Public evidence of traction is limited to practitioner and client testimonials on the company's own website, including accounts from a consultant clinical and forensic psychologist and a chartered clinical psychologist describing use of the Co-Therapist with clients between sessions.
