Growth hacking is a subfield of marketing focused on the rapid growth of a company. It is referred to as both a process and a set of cross-disciplinary (digital) skills. The goal is to regularly conduct experiments, which can include A/B testing, that will lead to improving the customer journey, and replicate and scale the ideas that work and modify or abandon the ones that do not, before investing a lot of resources. It started in relation to early-stage startups that need rapid growth within a short time on tight budgets, and also reached bigger corporate companies.
