Amazon

Retail flywheel + AWS cross-subsidy: low-margin commerce funded by high-margin cloud.

Amazon's $638B machine runs on a flywheel where each part feeds the next — and on cross-subsidy, where AWS ($108B) and ads ($56B) bankroll retail aggression. The lesson for founders: your margin engine and your growth engine can be different products. Example profile — reconstructed from public sources to show founders what a completed StartupKit showcase page looks like. Amazon is not a StartupKit customer.
