If you’ve ever inherited a financial model that made you want to pull your hair out, you know exactly what this means. We all build models in ways we've grown comfortable with—methods shaped by experience and what we've seen around us. But financial models aren’t just for us. They need to be shared with teams, investors, banks, and stakeholders. That’s where the FAST Standard comes in. Using FAST means models become easier to use, more accurate, consistent, and better for collaboration. It’s not about losing your style—it’s about speaking a common language everyone can read. Ready to stop wrestling messy models? What’s the biggest spreadsheet nightmare you’ve faced? #WeAreGridlines #FASTStandard #FinancialModelling #ModelAudit
