What Is a Startup? Core Vocabulary in Context
The word startup is everywhere in tech, but it is often used loosely. Not every new company is a startup, and the distinction matters in business English. This lesson defines the core startup vocabulary precisely, using real companies as examples, so you can talk about the startup world with confidence.
What makes a startup a startup
A startup is a young company designed to grow very fast. The defining feature is not size, age, or technology; it is the intent to scale. Paul Graham, co-founder of Y Combinator, put it simply: a startup is a company designed to grow fast.
This separates a startup from a small or medium business (SMB). A local bakery or a freelance design studio is a small business, but not a startup, because it is not built to scale to millions of users. A software company that aims to serve the whole world is a startup.
The vocabulary ladder
| Term | Meaning | Real example | | ---------------- | ---------------------------------------------- | -------------- | | Startup | Young company built to grow fast | Airbnb in 2008 | | Scale-up | A startup that has found growth and is scaling | Stripe in 2015 | | Unicorn | Private startup valued over $1 billion | Stripe, Canva | | Bootstrapped | Grown without outside investment | Mailchimp | | VC-backed | Funded by venture capital | Uber, Slack |
Notice the trajectory: a company is a startup, finds its growth and becomes a scale-up, and if its valuation passes $1 billion while still private, it becomes a unicorn.
Bootstrapped versus VC-backed
These two words describe how a company is funded.
- Bootstrapped means the founders grew the company using its own revenue, without selling shares to investors. Mailchimp famously bootstrapped for 17 years before being acquired for $12 billion. Bootstrapping means full ownership but slower growth.
- VC-backed means the company has taken investment from venture capital (VC) firms in exchange for ownership. VC-backed companies can grow faster but give up equity and control.
You will hear: We're bootstrapped or We just raised a VC round.
Exit, IPO, and acqui-hire
An exit is how founders and investors turn their shares into cash. Two common exits:
- IPO (Initial Public Offering) : the company sells shares to the public on a stock exchange. Airbnb had its IPO in 2020.
- Acquisition : another company buys the startup. Instagram was acquired by Facebook in 2012.
- Acqui-hire : a company is bought mainly to hire its team, often for its talent rather than its product.
Common mistakes
- Calling every new business a startup. A new restaurant is not a startup unless it is a chain designed to scale nationally.
- Confusing unicorn with monopoly. A unicorn is about valuation, not market dominance.
- Bootstrapped since versus for. Say bootstrapped for three years (duration), not bootstrapped since three years. Since takes a point: bootstrapped since 2020.
Practice
Write three sentences using three different terms from this lesson:
- A sentence using startup or scale-up: _
- A sentence using bootstrapped or VC-backed: _
- A sentence using unicorn, IPO, or acqui-hire: _
Example: Canva is an Australian design scale-up that became a unicorn.
You now have the core startup vocabulary. In the next lesson, you will go deeper into product-market fit, the concept that separates startups that succeed from those that stall.
