# Sigma Advisory LTD
Sigma Advisory is an operational advisory firm based in London that helps growing businesses build scalable systems and capable leadership. They work with UK and international SMEs with turnover between £200k–£10m and 10–150 employees who are experiencing growth-related operational strain.
The firm's core insight is straightforward: businesses stall not from lack of ambition, but because operational structure fails to evolve with scale. Sigma replaces the chaos of founder-dependent organisations with structured systems, clear accountability, and distributed leadership capability.
Their approach is distinctive in treating systems and leadership development as inseparable. Rather than implementing processes in isolation, they strengthen both simultaneously across four defined phases: diagnosis of actual issues, design of solutions, execution support, and transition to independence.
Sigma serves founders and directors ready for structural improvement rather than cosmetic fixes—those who understand that professionalising operations requires parallel investment in people and processes. Their client base includes rapidly scaling tech companies and businesses entering transition phases where founder-led management no longer works.
The firm's case studies (Sabre56, Solstice Data) demonstrate tangible outcomes: moving companies from startup chaos to scale-ready operations with empowered teams and standardised global processes. Engagements are clearly scoped and delivered in defined phases, ensuring predictable outcomes rather than open-ended consulting relationships.
