Business cases smarter, faster, cheaper

Business Case Guru (BCG) is a software application that supports users to write business cases - documents that appraise the case for investment – following the UK Treasury Five-Case-Model.

Users input project information and interact with BCG app making strategic decisions, as they are guided through the preparation of a business case.

BCG was founded by business case experts Stefan Sanchez and Fiona Waters, who bring over 55 years of combined experience in business case preparation and review, business case training and investment appraisal.

BCG aligns with government and institutional requirements ensuring that every case is compliant, clear and fit for purpose. BCG software is compliant with UK public sector standards and data is not shared with any third party or used for learning.

BCG works in partnership with Cybix.ai, a UK-based AI specialist with a strong track record of delivering automated solutions to high-profile public and private sector organisations.

Smarter

Raise the quality, clarity and impact of every business case

BCG delivers smarter, clearer, fully Green Book-compliant business cases — consistent, evidence-based and rigorous across all five cases.

The logic is strengthened without taking over the thinking. Users retain full ownership of direction and judgement, while BCG replaces the subjective "sell" with transparent, defensible analysis — giving decision-makers what they need to compare options fairly and invest with confidence.

Faster

From idea to approval at rapid pace

Write business cases in hours, not weeks.

BCG cuts drafting time dramatically — generating structured, review-ready content from user inputs, organised around themes, evidence and logic, fully aligned with the Five-Case Model.

Teams interact with content from the outset, building and iterating section by section. Whether checking sources, refining tone or working through options in a live workshop, BCG keeps pace — producing high-quality drafts in real time, not days later.

BCG doesn't replace human expertise. It frees it.

Cheaper

Developing business cases is resource-intensive — demanding significant staff time and costly external consultancy.

BCG automates the labour-intensive drafting work, converting strategic inputs into structured, expert-quality documentation while keeping ownership of the thinking firmly with the user. The result is a dramatic reduction in time, cost and reliance on external resource.

Less consultancy dependency. Faster delivery. Teams freed to focus on the decisions and judgements that only they can make.

Reduce costs while increasing control, consistency and quality
