Growth: my areas of focus

Increase Customer Acquisition

Starting from acquisition channel and tactics up to onboarding funnels, successful companies should have a continuous flow of new customers and not waste marketing dollars.

Things I can help you with:

  • Increase your traffic and / or leads
  • Optimise your marketing channels & campaigns. I cover all things PPC, Display & Retargeting.

  • Discover new acquisition channels
  • Create viral loops and network effects within your product that brings organic customers
  • Improve conversion rates across your funnel

Optimise Customer Activation

Attracting users is great, but not very useful if you ‘re struggling to activate them to start using your product. Nurturing and guiding your customers through your product’s happy paths is crucial for success. I will help your customers discover your “Aha!” moment and enjoy fully the benefits of your product.

Things I can help you with:

  • Improve your onboarding experience; Funnel, CX, UI and CRM
  • Automate your onboarding communications
  • Remove onboarding friction
  • Reduce your onboarding customers and improve unit economics

Improve Customer Retention

Solving Acquisition and Activation issues is solving half of the problem. If customers don’t stick to the product or service, it probably means that you don’t have a sustainable funnel or even business, and you will struggle to achieve sustainable growth. Retention is the core of growth hacking.

Things I can help you with:

  • Accurate retention analysis
  • Advanced techniques for retaining users, as well as reactivating churned cohorts.
  • Retention loops within your product and your communications
  • Improvements of LTV

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.
