    Growth: my areas of focus

    Frequently asked questions

    Growth Hacking is a process of rapid experimentation across the marketing funnel, product development, sales segments, analytics and other areas to identify the most efficient ways to grow and scale a business. 

    While personally I hate the term “Hacker” in the growth context (would be more suitable to use a term such as Growth Manager instead of Hacker), the function of a Growth Hacker the past 3-5 years has proven to be an effective skillset that covers a broad range of knowledge and has the executional capacity to deliver results autonomously or as part of a wider growth team.

    The answer is simple here. Is the channel actually trackable? If so, I can apply growth tactics.

    The differences are very slim despite the fact that both terms are widely abused recently. In general, growth hacking has less to do with traditional marketing functions such as brand or PR and is more focused in measurable, quantifiable channels that deliver predictive results. However, both together deliver the best results.

    Typically, I run various experiments for at least 2-3 months before I deliver a scalable and repeatable strategy. But initial results might show up as soon as 48h after kick-off – it all depends to the product, industry, level of previous optimisation and traffic, existing team resources etc.
