San Fran Sim - a startup tycoon game built on real SaaS unit economics

Founders learn unit economics from spreadsheets and blog posts that never punish a bad call. This one does. Free in the browser, no signup: found a startup in a garage and grow MRR to IPO while burn rate, churn and bug outbreaks fight back.

- MRR, churn, LTV and CAC are the actual mechanics - a pricing pivot instantly recalculates your growth curve, not some abstract score
- Shared seed challenges: run the exact same starting parameters as another founder and compare where your decisions diverged
- Free, no signup, one browser tab - "just one more run" pacing

Strongest as a gut-check for unit-economics intuition, not a strategy manual; the $25k starting runway makes the early garage phase too forgiving, so the real pain only shows up once you scale.
