What Business Case Guru does
Expert guidance through every strategic decision.
Business Case Guru (BCG) is a software application that helps users write business cases—documents that appraise the case for investment—following HM Treasury’s Five Case Model.
Users input project information and interact with the BCG application, 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 more than 55 years of combined experience in business-case preparation and review, business-case training and investment appraisal.
BCG structures every case around HM Treasury’s Five Case Model, so what your team submits is complete, consistent and ready for review. The platform is hosted in UK AWS regions, aligned with the NCSC Cloud Security Principles, and compliant with UK and EU GDPR. Customer data is never shared with third parties or used to train AI models.

Transcript
Writing a public sector business case shouldn’t take months.
But for most teams, it still does.
The UK public sector spends over 1.7 billion pounds a year producing them.
Weeks of drafting.
Backlogs of approvals.
There has to be a better way.
Meet Business Case Guru.
It writes complete public sector business cases in days, not weeks.
First you provide project information.
Describe your project.
Add your budget, location, and sector.
The system searches gov.uk to flag which policy frameworks apply and which it can reference.
Upload your evidence.
Then save.
With project information complete, BCG generates the Strategic Case for you to review and edit.
Real citations, real funding numbers, real policy references.
The user approves each section until the Strategic Case is completed, then moves onto the other cases.
And the same for every other case—Economic, Commercial, Financial, Management.
BCG generates the strategic case, section by section.
You review and approve every step.
A complete business case, all Green Book aligned, built with you in control.
And you can export to share a draft whenever you like, at any stage.
Complete audit trail, ready when you need it.
Faster business cases, done in days.
Fully Green Book compliant.
Built on the Five Case Model, trusted by UK public sector teams.
