Our secret

01 - MarvelFoundation

During this process, we gather, structure, analyze and enrich internal and external data, which will become the foundation for data-based growth.

First, our data exploration engines will analyze your internal data, such as your historical marketing data, sales data and your audience behavior UX data. Furthermore, we’ll establish your marketing data infrastructure inside our DataHub, delivering real-time full-funnel insights.
Based on this overview, we are ready to enrich your data. What does this mean? We’ll profile your customers based on up to 52 variables, resulting in a precise understanding of your online target audience. Additionally, we’ll be giving you real-time insight into your competitor traffic, so that you’ll be able to stay on top of your market. Everything is available in one place: our Data Hub. Now, with the data-based opportunity package, you’re ready to move to the MarvelTest phase.

02 - MarvelTest

The MarvelTest algorithm tests carefully-planned audience profiles, marketing campaigns and landing pages on all relevant channels. Inductive findings from the MarvelFoundation stages are validated by conducting a substantial amount of experiments on the entire online funnel.

Based on our findings during the MarvelFoundation phase, new testing funnels will be established to validate our results through high-capacity testing.
Starting with a mix of channels, audiences, ad sets and landing pages that will go live. Our audience-proposition fitting algorithm will find funnels that perform at the maximum customer acquisition cost that your business model can bear. All real-time results will be available inside our Data Hub.

03 - MarvelLive

In this stage, the complete focus is on sustainable and repeatable revenue growth. This is the moment your business is able to scale with a mitigated risk.

Scaling is key during the MarvelLive phase. The funnels that performed at the maximum CAC level in the MarvelTest phase will be scaled, resulting in higher revenues.
Furthermore, during this phase, the focus will shift from new client acquisition towards full-funnel optimization, including conversion rate optimization and mailing automation. Continuous analysis and optimizations will not only result in a lower CAC, but also a higher customer lifetime value. The result? A business model that is more efficient. Based on this foundation, our clients continue with our inventive, advanced, high capacity testing methodology.

The influence of competitor knowledge on business decision making

In 2022, we’ve reached a time where the on- and offline competition is bigger than ever, a time when everyone can join the race. And so it is crucial to get an understanding of your competitors and the position your business holds within the industry. Because of that, the first step is choosing the right competitors based on a variety of elements that make them relevant to your business. It would be most obvious to look a the products or services they sell, right? However, the technology they use, their business model, target audience, and marketing channels are also relevant. Based on these criteria, you can conduct various analyses to study and compare your strategy.
