Startup
A startup is a young company built to find and scale a repeatable, high-growth business model under conditions of high uncertainty. It is distinguished from a traditional small business by its pursuit of rapid growth rather than steady-state operation, defined by what it is searching for (a working, scalable model) rather than by its age, size, or industry.
The two most-cited definitions come from the founders of the modern startup playbook. Steve Blank: "A startup is a temporary organization designed to search for a repeatable and scalable business model." Paul Graham of Y Combinator: "A startup is a company designed to grow fast." Both definitions point to the same idea, that the defining feature of a startup is the search for and pursuit of high-growth scale, not the product, the founder, or the office. Most US startups are organized as Delaware C Corporations to enable venture investment, and most operate on outside capital (SAFEs, convertible notes, and priced rounds) for years before reaching profitability or an exit. Failure rates are high: CB Insights data has consistently shown that roughly 70 percent of venture-backed startups shut down or fail to return capital within their funding lifecycle, and surveys of startups generally put the long-term failure rate near 90 percent. A startup graduates out of "startup" status when growth becomes predictable, the business model is proven, and the company starts operating like a scaling business rather than a search experiment.
Ryan's Take
The most useful distinction is what you do with success. A small business owner who hits $5 million in revenue is winning. A startup that hits $5 million is usually told to get to $50 million or get out, because the investors, the equity, and the team incentives all assume a much larger outcome. Picking the wrong category isn't a personality flaw, it's a structural mistake that decides who you raise from, what you owe them, and what success even looks like. Be honest about which one you're building before you take the first check.
What founders get wrong: Calling any new business a "startup." The label carries real consequences: C Corp incorporation costs, venture investor expectations, equity grants instead of salary, and an exit-or-die endgame. If you're building a profitable lifestyle business, that's great, and it's not a startup.
