Why build financial models with AI instead of from a blank spreadsheet?
The short answer
Because the AI already knows the structure, how an income statement links to a balance sheet and cash flow, what assumptions a SaaS or D2C model needs, so you skip hours of formula plumbing and go straight to the decisions: your pricing, hiring plan and growth assumptions. Describe your business in plain English and tools like Claude in Excel or ChatGPT will draft a linked, working model in minutes that you then sanity-check and adjust. Founders who tried it report finishing in under an hour what used to take days, and the model is easier to change when an investor asks "what if growth is half that?"
