Hey Product Hunt — we built Reef to take the grunt work out of building financial models. Tell us your use case (projection, forecast, ROI analysis, fundraising deck) and we’ll show you a generated downloadable Excel with formulas, polished styling, and everything wired up. We’d love to hear: what’s the one spreadsheet task you dread the most? Reply with your scenario and we’ll share a quick example — or walk you through how Reef would build it step-by-step. Excited to get your feedback and see what models you want automated. Ask us anything — we’re listening!

I have a use-case idea… curious if it would work for it. It’s an excel task I deal with often & so do many others across the industry I work in… would be a game-changer if it could handle it effectively. Please dm me!
