A Startup's Initial Market Is Not Its Final TAM
Parekh argues that total addressable markets are not static. A company can enter through a narrow product or customer segment and later expand its offering, as Uber moved beyond the original black-car market through UberX and other services.
- Early-stage market sizing is an educated estimate rather than a fixed fact.
- Investors commonly underestimate markets that can expand through product evolution.
- A narrow initial use case can act as a Trojan horse into larger markets.
- Founder quality and pattern recognition matter when expansion cannot yet be measured.
