Business Case Guru (BCG): smarter, faster, cheaper business cases.

Writing a Five Case Model business case usually takes weeks, ties up your best people, and burns through consultancy budgets.

BCG is a secure SaaS platform for writing business cases, with full rigour and designed to support Five Case Model and HM Treasury Green Book compliance.

Here's how it works.

You bring the strategy and the judgement calls only a human can make. BCG does the heavy lifting: structured drafting, linking your evidence, and keeping everything aligned to HM Treasury Green Book guidance.

You stay in control and own every word, while cutting drafting time by up to 70–80%.

Built for the real world of government, the NHS, and the wider public and private sectors, BCG delivers:

•⁠  ⁠Business cases that are designed to support Five Case Model and Green Book compliance
•⁠  ⁠Evidence-based content built in real time, organised around the five cases: strategic, economic, commercial, financial and management
•⁠  ⁠Links to public sources, so you can question, refine and confidently defend every recommendation
•⁠  ⁠A workshop-ready approach where decisions are made in real time, so the business case is never held up
•⁠  ⁠A major saving in both staff time and external consultancy costs
•⁠  ⁠Security you can trust: UK data residency, UK and EU GDPR compliance, and your data is never used to train AI

BCG was founded by business case experts Stefan Sanchez and Fiona Waters, who bring more than 55 years of combined experience in preparing, reviewing, training and appraising business cases.
