Growth hacking is an experiment-driven approach to rapid business growth, often used by startups and early-stage companies with limited budgets. It combines marketing, product, data, and creativity to identify scalable methods for acquiring and retaining users.

Core elements of growth hacking are:

• Hypothesis-driven testing (A/B tests, landing pages, onboarding flows)
• Viral loops and referral programs
• Product-led growth tactics (e.g., freemium, waitlists)
• Leveraging data and user behavior for optimization
• Speed > perfection
