Definition (canonical)
A startup is a temporary organization searching for a scalable, repeatable business model — not a small version of a big company. The definition (Steve Blank's) carries the whole distinction: a bakery executes a known model from day one; a startup doesn't yet know what exactly it will profitably sell to whom, and its job is to find out fast.
Search mode changes everything
Because the model is unknown, startup practice inverts corporate logic: hypotheses instead of plans, MVPs instead of finished products, iteration and pivots instead of roadmap fidelity, learning speed as the core KPI. The milestone that ends the search is product-market fit — demand that pulls instead of being pushed. Before PMF, scaling anything (sales teams, marketing budgets) industrializes a mistake; after PMF, the company flips into execution mode and the startup playbook gradually retires.
The economics: growth first, profit later — deliberately
Startups accept losses BY DESIGN: capital buys speed toward a market position whose value dwarfs the burn. That trade only makes sense with (a) a market big enough to justify it, (b) improving unit economics underneath the losses, and (c) runway managed like oxygen. Funding stages map to proof: pre-seed/seed buy the search, Series A buys scaling a found model, later rounds buy market capture — each round priced on evidence, not narrative alone (how VC thinks).
When a startup stops being one
Three honest exits from the category: found and scaled — the model works, growth is operational, the company is simply a growth business now; lifestyle plateau — a fine, profitable niche business emerges (a great outcome VC economics just isn't built for); death — the default outcome, since most searches fail. The label matters less than the mode: teams that keep "acting like a startup" (perpetual pivots, burn as identity) after the search is over destroy exactly the value the search created.
FAQ
Is every new tech company a startup? No — a dev agency executes a known model. Technology is common in startups because software scales; it is not the definition.
Does a startup require venture capital? No — bootstrapped searches exist and keep full ownership; VC compresses time at the price of dilution and a growth mandate.
How long can the "startup" phase last? Typically years, not decades — searches that never converge are answered by the market, and runway enforces the deadline.
