A startup is a newly established business designed to solve a problem with a scalable, innovative solution. Unlike traditional businesses, startups aim for rapid growth and often operate under high uncertainty with the goal of disrupting existing markets or creating new ones.
A startup is fundamentally different from a small business. While a small business (like a local restaurant) aims for stable, predictable revenue in a known market, a startup is an experiment designed to find a scalable, repeatable business model in uncertain conditions. Paul Graham defines it as "a company designed to grow fast." Key characteristics: (1) Scalability - can grow revenue without proportional cost increases (software scales better than restaurants), (2) Innovation - solves problems in new ways or creates new markets, (3) High risk/high reward - 90% fail but successful ones can become unicorns, (4) Temporary state - you're either growing into a company or failing, not staying a "startup" forever. Most startups follow a lifecycle: Idea → Validation → MVP → Product-Market Fit → Scale → Exit (acquisition/IPO) or failure. The term became popular in the dot-com era (late 1990s) and was refined by the Lean Startup movement (2010s). Today, "startup" often implies tech focus, venture funding aspirations, and exponential growth goals.
Airbnb: Started as 3 roommates renting air mattresses during a conference. Scaled to $100B+ valuation by solving travel accommodation differently.
WhatsApp: 55 employees when acquired for $19B. Demonstrated extreme scalability—millions of users with tiny team.
Zerodha: Bootstrapped Indian startup that became profitable unicorn without VC funding, disrupting traditional brokerage.
Startups aim for rapid, scalable growth and market disruption. Small businesses target stable, local revenue. A bakery is a small business; a food delivery app is a startup.
Until it finds product-market fit and achieves sustainable growth (typically 3-7 years) or until it fails. Once stable and profitable with proven model, it's just a "company."
No. 90% of startups are bootstrapped. VC funding is needed only if you need massive capital to scale fast before competitors do.
