Client Success Stories + Our Track Record

Over the past 12 years, we have partnered with more than 2,000 entrepreneurs and companies across every stage of the business lifecycle. Each month, we work with an exceptionally diverse portfolio, ranging from self-employed professionals and microenterprises taking their first commercial steps, through to major corporations including National Rail, PwC, and the London Mayor's Office, which require strategic project consulting.

Our unique market position spans the entire UK business ecosystem. We've guided hundreds of entrepreneurs through the establishment of franchises with leading brands, including Costa Coffee, Subway, KFC, and Vodafone, while simultaneously supporting Cambridge University spin-outs in securing investment from top-tier venture capital firms such as Atomico, Balderton Capital, and Index Ventures. Our trusted partnerships with prestigious law firms, including Mishcon de Reya LLP, demonstrate the professional recognition of our expertise in complex business development.

Our client base encompasses every conceivable industry and cultural context, from cutting-edge drone technology and AI startups to authentic Afro-Caribbean restaurants and luxury fashion ateliers. Whether you're a sole trader seeking business formalisation, a growing SME preparing for international expansion, or an ambitious startup targeting institutional investment, we deliver the same rigorous approach to strategic planning and measurable outcomes that has earned the confidence of both Fortune 500 companies and first-time entrepreneurs.

The case studies below represent a curated selection from our extensive client portfolio, demonstrating not only the remarkable breadth of industries we serve but also the consistent delivery of tangible, measurable results. Our clients have successfully secured funding across the complete spectrum - from government-backed Start Up Loans through to multi-million-pound rounds from leading venture capital firms, alternative finance providers, and traditional high street banks.

From supporting Gambian entrepreneurs establishing cultural restaurants in Glasgow to guiding publicly listed companies through strategic expansion, these stories illustrate our ability to adapt institutional-grade expertise to diverse business contexts while maintaining consistently high standards of execution. Each engagement reflects our commitment to understanding unique market challenges and developing tailored strategies that drive sustainable growth, competitive advantage, and long-term success across the entire UK business landscape.

The companies named on this page represent a curated selection from twelve years of consulting work supporting more than 2,000 entrepreneurs, businesses, government bodies, and major corporations. Many client engagements involve confidentiality requirements or are subject to non-disclosure agreements, and many more are simply too numerous to detail individually.

The case studies, enterprise clients, franchise brands, and funding partners listed below have been selected because their outcomes are verifiable, their relationships with SGI are documented, and their stories illustrate the diversity of strategic work we deliver across business stages, sectors, and capital structures. The selection is representative rather than exhaustive.

Our consultancy expertise extends beyond startup development and franchise operations to encompass strategic project work and ongoing business consulting for major corporations, government bodies, and publicly listed companies. 

This enterprise-level experience provides valuable insights and proven methodologies that we apply across our entire client portfolio, regardless of business size.
