Could you make the call a CFO makes? Find out in five minutes. Run the money of a fictional company. Every decision moves its value live, and the Board grades you from A to F. No subscription. No ads. Free to start. WHAT YOU GET • Real CFO decisions: cash, debt, budgets, and which projects to fund or kill • Instant feedback: your grade, the Board Chair's verdict and the best call available • Your rank against a simulated field of CFOs • A report that explains the finance behind every call • Six visual mini-games instead of spreadsheets • Plain-English explanations, no finance degree required • Start playing in about 90 seconds, with no account GRADED ON YOUR DECISION, NOT YOUR LUCK Market shocks can hit any company. Your grade compares your call with the best one available in that exact situation, so a smart decision in a bad quarter still earns an A. PLAY WITH YOUR TEAM • Design the game: industry, company size, difficulty, and 3, 5 or 10 decisions. • Share one invite link. Players type a name and play in any browser, with no app and no account. • Watch a live dashboard: who joined, who finished, every decision, grade and value created. • Run the debrief with team analysis and ready discussion questions. • Export a results PDF, image or CSV. Results are recorded as players play and cannot be edited. • Team Pass is priced per player, in packs of 5, 10, 25 or 50. THE WEEKLY CFO CUP Every Monday brings a new free Cup: three decisions, one company and one set of market shocks, identical for everyone that week. Share your result card and keep your streak alive. PERFORMANCE CERTIFICATE Finish a full Pro run or a team game and get a certificate in your name with your grade, EVA score, career rank, date and a verification link. One tap adds it to LinkedIn.
