This simulation renders the innovation pipeline of a startup ecosystem as a literal 3D funnel. Ideas spawn continuously and travel toward four sequential gates — Validation, MVP Build, Product-Market Fit and Scale — each a probabilistic checkpoint whose pass rate you control directly. The funnel's own geometry narrows at every gate to match the shrinking survivor count, so the compounding effect of four independent Bernoulli trials (P = p₁·p₂²·p₄) becomes something you can watch happen rather than just calculate. Live readouts track total ideas spawned, how many reach product-market fit, how many ultimately scale, and the running survival rate against the slider-implied theoretical value — showing concretely how identifying real market needs, executing well, and securing funding compound into the small fraction of startups that succeed.
