What Cranstoun does

Cranstoun is a UK-registered social justice charity (Registered Charity No. 1061582) operating for over 50 years across England, delivering person-centred harm reduction, substance use treatment, criminal justice, domestic abuse, housing and homelessness, and children and young people's services. In 2024/25 the organisation supported over 34,000 adults, children and young people across at least ten commissioned regions including Worcestershire, Sutton, Sandwell, Wokingham, the Royal Borough of Windsor and Maidenhead, Derby, Dudley, Oxfordshire, Warwickshire and Buckinghamshire, with outcomes reported at 94% Housing First accommodation, 94.5% care plan achievement for young people, and 97% of service users rating staff as friendly and approachable.

The core technology assets are Drugbot, an AI-powered NLP harm reduction chatbot co-developed with Substancy that served over 6,040 unique users in its first year, and WODDAS, a wearable overdose detection device pilot developed with Manchester Metropolitan University, St Paul's Hostel and Queen's University Belfast. Sub-brands include DIVERT (a registered pre-arrest drug diversion programme operating with Thames Valley Police), WiSE (women-only harm reduction spaces), Here4YOUth (young people's services), and an Individual Placement & Support (IPS) employment programme. The technology is enabled by AI modality limited to text and is integrated into, rather than central to, the human-delivered service model.

Revenue is generated through three streams: managed-service contracts commissioned by local authorities and statutory bodies (the primary income source), philanthropic donations including text-donation keyword campaigns and major-donor appeals, and fundraising through charity running events such as the London Marathon and regional half marathons. The go-to-market is direct service delivery via self-referral and professional referral pathways from GPs, probation, housing providers and police, supplemented by digital harm reduction access via Drugbot and B2B training and consultancy. Cranstoun holds UK GDPR, Charity Commission, Fundraising Regulator, Modern Day Slavery Act, and Investing in Volunteers accreditations, and employs between 251 and 500 staff.

Product overview

Cranstoun is a social justice charity providing a comprehensive portfolio of harm reduction, treatment, and support services rather than a traditional software product company.

The primary digital product is Drugbot, an AI-powered 24/7 harm reduction chatbot. Additional innovations include WODDAS (wearable overdose detection devices) and the pharmacy naloxone pilot. Services span harm reduction (needle exchange, naloxone), treatment (prescribing, detox), recovery support (IPS employment support, peer mentors), and broader social justice work (housing, domestic abuse, criminal justice). Breaking Free Online provides a smartphone companion app for recovery support.
