Colossus Academy

Financial modeling and valuation, from first principles.

A complete, plain-language path from no finance background to professional fluency. Learn to read the three financial statements, build a working model, and value a company with a discounted cash flow and comparable companies. Every concept is anchored in one real fiscal year of Apple, so the numbers reconcile as you move from module to module.

The approach

Built the way an analyst actually learns.

01

Plain language, defined inline

No assumed background. Every term, like accrual accounting or deferred revenue, is explained the first time it appears.

02

Real numbers, real filings

One fiscal year of Apple and Microsoft, every figure reconciled line by line to the company's own 10-K on SEC EDGAR.

03

Work it yourself

No auto-calculators. You compute each answer by hand; the page checks it and walks through the full solution when you are wrong.

04

Excel, the analyst's way

Follow-along spreadsheets that teach the convention the profession uses: blue font for inputs, black for formulas.

Curriculum

Sixteen modules, foundation to valuation.

Work through them in order. Each builds on the last, and earlier ideas resurface in later practice so they stay fresh.
