Growth hacking is a marketing approach that focuses on fast and cost-effective growth, especially for start-ups and online businesses. Unlike traditional marketing methods, which often rely on long-term strategies and larger budgets, growth hacking uses creative, innovative and experimental tactics to quickly gain users, customers and sales.

Growth hackers often use data-driven techniques and analyses to identify which measures have the greatest impact on growth. Some examples of growth hacking strategies include viral campaigns, the use of social media and influencers, optimisation of customer acquisition and retention, and continuous improvements to the user experience.

The main aim of growth hacking is to accelerate a company's growth quickly and with minimal use of resources in order to gain a competitive advantage over the competition.
