startup
A young startup seeking a rapidly scalable business model with a new idea under high uncertainty, often using investor capital.
In plain terms
A startup is a young company that is not yet sure what will work: it experiments with a new product or service while searching for whom, at what price, and how to sell it. It is not its size or age that makes it a startup, but the fact that it prepares for rapid and large growth.
Analogy: a corner bakery and a startup are both businesses, but the bakery is like a carefully planted fruit tree that reliably bears fruit year after year. A startup is more like a rocket experiment: many of them never take off or crash early, but those that reach orbit go very far.
In the AI era, startups are particularly important because many new AI tools, chatbots, and agents originate from such companies, alongside the developments of large technology firms. Meanwhile, AI itself is changing them: a small team today can build a product with the help of agents that previously required dozens of people.
How it works
- Founders identify a problem that many people or companies want to solve and devise a novel solution for it.
- They quickly assemble a simple but usable first version and test it on real users to see if anyone actually needs it.
- They improve based on feedback, or if necessary, change direction; they repeat this until the product and the market find each other.
- At the beginning, they mostly operate from their own savings or initial revenues. For rapid growth, many raise external money from investors, who in return receive a share of the company; the money usually arrives in several rounds as the company proves itself.
- The story's ending can take several forms: the company ceases to exist, is acquired by a larger corporation, goes public, or matures into an independent, profitable large enterprise.
An everyday example
You download a new application where an AI agent handles your appointment scheduling or bill organization for you. The first month is free, the interface changes weekly, and in six months either everyone uses it, or you receive an email that the service is discontinued. You have likely encountered a startup product.
Who is affected
A common misconception
Limits and risks
- Most startups cease to exist within a few years, so do not make their product your only irreplaceable tool in your life or company.
- If the service goes down or the company is acquired, the fate of your data may become uncertain; check in advance whether you can back it up.
- The free or very low introductory price is often funded by investor money and may rise significantly later.
- Startups' confident promises and news about company valuations often reflect future hopes rather than proven results.
Similar, but not the same
- small and medium-sized enterprise (SME) – An SME is a size category (based on headcount and revenue) and typically runs a proven business model, aiming for predictable, slower growth. A startup searches for a new model and aims for explosive growth; by size, most startups are themselves small businesses.
- scaleup – A scaleup has found its working business model and is expanding rapidly, while a startup is still searching for it.
- unicorn – A unicorn is a startup not yet listed on a stock exchange, valued by investors at least at $1 billion; this is a rare, narrow group of startups, and the valuation is an estimate, not revenue or profit.

A brief history
The startup world formed around technology companies in California's Silicon Valley in the second half of the 20th century and became globally known with the late 1990s boom of internet companies (the dot-com bubble). The modern experimental approach was popularized widely by Eric Ries' 2011 book, The Lean Startup, building on the work of Steve Blank.
Where things stand
A startup is not a legal form of company but a long-established type of business and an everyday word. In late 2026, a large share of venture capital and investor attention is turning to AI-based startups. Very small teams that delegate much of their work to agents are becoming more common.
