Startup finance review: runway and unit economics lessons

Our course "Brojevi koji vode startap" teaches founders the numbers behind a startup. Before students rely on it, we want someone who has actually run these numbers to check the first chapter. You will review the lessons, the worked examples and the exercise answers for correct formulas, realistic assumptions and clear explanations of runway, burn and unit economics. You will also flag anything that reads as financial advice rather than education. Deliverable: a review table with lesson, claim, problem, suggested fix and source, plus one worked example you would add. Done means: every number and formula in the chapter has been checked and every error has a proposed correction. Must know (mandatory): native Serbian; hands-on startup finance as a founder, CFO or analyst; CAC, LTV, burn and runway modeling; Excel or Google Sheets. Nice to have: investor or accelerator experience; teaching.
