1. What is a Startup?
A startup is a newly formed business designed to solve a problem in a scalable and repeatable way. Unlike traditional small businesses, startups aim for rapid growth and often rely on innovation and technology.
According to Harvard Business Review, startups are defined more by their growth potential and uncertainty than by their size. [1]
Understanding what a startup truly is will help you build a business strategy that aligns with its inherent risk and reward structure.
2. Mindset: What it Takes to Build from Zero
Before you take any steps, the most important asset you need is a growth mindset. Successful entrepreneurs share certain traits:
Resilience and persistence
Creativity and problem-solving skills
Ability to learn quickly from setbacks
Strong communication and leadership skills

Pro Tip: Being comfortable with uncertainty isn’t optional — it’s essential.
3. Ideation: Finding and Validating Your Startup Idea

Here’s how to refine your idea:
Brainstorm Problems and Solutions
Compile a list of problems you encounter personally or in your industry.
Validate the Idea
Validation reduces risk. You can validate by:

Surveying your target market
Testing interest using pre-orders
The Lean Startup methodology emphasizes rapid iteration and early feedback. [2]
