What Six Sigma does
Pentagon Training Ltd, operating commercially as Six Sigma, is a UK-based private professional training organization headquartered in Maidenhead that delivers Lean Six Sigma, Six Sigma, Lean, and Kaizen certifications. The company has been operating for approximately 21-28 years (sources internally vary between 2004 incorporation and a current '28 years' brand banner) and operates from 90+ UK classroom venues spanning England, Scotland, Wales, Northern Ireland, and the Republic of Ireland. Course content is built around the DMAIC methodology and a belt-tiered certification structure (Yellow, Green, Black, Master Black Belt) delivered through four channels: in-person classroom, virtual instructor-led, self-paced 90-day eLearning, and bespoke onsite corporate delivery. The catalog of 45+ courses extends into adjacent methodologies (Lean 5S, Value Stream Mapping, Kaizen Foundation/Practitioner, Kanban), agile frameworks (Scrum Master, Product Owner, CPAPM), compliance (GDPR Foundation/Practitioner/CDPO, Business Continuity), and data analytics tools (Minitab, Power BI, Tableau). The company reports training 120,981+ professionals globally and claims a 95% satisfaction rating; a network of 95+ accredited trainers delivers the curriculum.
The business operates a hybrid go-to-market combining B2B enterprise sales — onsite group training with bespoke content development for corporate clients — with direct-to-consumer self-service booking for individual professionals through sixsigma.co.uk. Revenue is generated primarily through one-time course fees (published prices range from £995 for 5S virtual training to £8,995 for Black Belt classroom courses), supplemented by Knowledge Pass (12-month prepaid) and FlexiPass (6-month prepaid) subscription-style contracts that lock corporate buyers into multi-attendee training commitments. Marketing is predominantly organic, anchored by SEO-focused blog content (e.g., Six Sigma Control Chart, CTQ, 5S methodology articles), email campaigns with up to 40% discount offers, and social media presence on LinkedIn, Facebook, and Twitter. Customer segments span Corporate Enterprises (primary), individual professionals seeking career credentials, SMEs requiring cost-effective team training, and vertical-specific buyers in healthcare (NHS), financial services, universities, charities, and transportation. The company is privately held under UK company registration (No: 3011290), appears founder/management-controlled, and has no disclosed external investment, M&A, or leadership transitions.
