Excel & AI Financial-Modeling Sprint

Build a three-statement model, forecast with drivers, run a DCF, and pitch a company like a pro. In this 3-week sprint, GPT helps you work faster—so you can walk away with real valuation skills and a polished investor deck.

The project built a three-statement financial model for a public company, created driver-led forecasts, and ran a discounted cash flow valuation. Work included assembling source filings, structuring forecast drivers, and producing valuation outputs and presentation materials using Excel and GPT-assisted workflows.
