Stamma

What Stamma does

STAMMA (legally The British Stammering Association) is a UK-registered charity founded in 1978 and rebranded under its current name in 2019. The organisation is the largest UK membership body representing people who stammer, serving 'thousands' of members nationally across England, Wales, and Scotland (charity numbers 1089967 and SC038866). Its service portfolio includes a free helpline, webchat and email support, an advocacy service for discrimination cases, family support, an employment support service, training programmes for organisations, speaking circles, and a biennial conference (STAMMAFest). The organisation also operates a Minecraft Club for children who stammer and a Your Voice storytelling platform, alongside a merchandise shop and award-winning awareness campaigns (Space To Stammer, Don't Jump In, It's How We Talk, Find The Right Words).

The organisation does not develop proprietary technology products; its offering is service-led and human-delivered. Technology is used to distribute information (website, email newsletters, social media) and to support fundraising (JustGiving pages, Run for Charity event registration), but the core value proposition rests on community, advocacy, and direct support rather than software.

STAMMA's revenue model is donations- and fundraising-led. Income is generated through individual and corporate donations, challenge events (running, cycling, walking), legacy gifts, merchandise shop sales, and an emerging Training Service for organisations. Membership is free and functions as a community engagement and donation pipeline rather than a paid subscription. The organisation operates from London with a very small staff (1-10 employees) and is governed by trustees, registered with the Fundraising Regulator, and supported by volunteers.
