Startup = Growth
A startup is a company designed to grow fast. Being newly founded does not in itself make a company a startup. Nor is it necessary for a startup to work on technology, or take venture funding, or have some sort of “exit.” The only essential thing is growth.
Context & Ripple Effects
This essay compresses six years of Paul Graham's writing into a single definition. His 2006 case for dedicated startup centers and 2007's Future of Web Startups treated startups as an emerging institutional category; "Startup = Growth" strips that category to one test — designed, sustained growth — declaring newness, technology, venture funding, and exits all optional.
The pickup was unusually fast for an essay: Bill Gross, Chris Dixon, and Rob Go each pushed it through their feeds on publication day, meaning the definition reached the investor class immediately rather than diffusing slowly. That matters because whoever controls the definition controls who counts as fundable.
First-order effects
- Founders and investors gain a litmus test that reclassifies the whole field: any fast-growing company qualifies as a startup whether or not it takes venture money, builds technology, or plans an exit — and slow-growing new companies do not.
- For the YC-centered ecosystem Graham writes from, the essay states explicitly the bar his accelerator already selects on, giving the startup-hub model he argued for in 2007 a crisp admission criterion.
Second-order effects
- Investors who adopt the definition screen deals on measured growth rates, pulling attention and term sheets away from small businesses and lifestyle companies that had claimed the startup label on age or ambition alone.
- The boundary of the hub economy sharpens: companies outside the growth pattern have a weaker claim on accelerators, relocation-to-the-hub advice, and the service layer built around that world since Graham's 2006–2007 essays.
Third-order effects
- If growth-as-definition holds, the supporting institutions — accelerators, hubs, seed funds — increasingly orient around manufacturing compounding growth as their core product, narrowing what the word 'startup' covers industry-wide.
- A definitional claim this strong invites dissent over whether growth really is the only essential thing, and that running argument itself entrenches growth rate as the default yardstick even among critics.
The trend: Startup discourse is consolidating around a single measurable criterion — growth rate — with Graham's essays supplying the vocabulary that investors and accelerators adopt.
