Every company a data company!


Digitalization of markets and the individualisation of consumer behaviour increase the need for marketing automation. Effective use of customer data is key to structurally adapt to changing customer expectations in a digitalized and individualized market. That’s why our motto states: Every company a data company!

We focus primarily on marketing organizations in the consumer market and cooperate with independent experts. The relationship with customers prevails short term results. Our objective is to structurally improve data use with strategic advice and operational support. Our data maturity model defines current data maturity. Based on this starting point and in the context of the objectives of your organization we develop strategies and achieve operational results.

Organizational objectives and priorities related to the collection, storage, control, management, sharing and use of data are at the hart of what we do. Results are structurally improved when the data landscape, data technology, analytical techniques, capabilities, compliance and governance are balanced effectively.  A data strategy assures this balance and sets priorities.

Data Strategy

A data strategy explains how your organization realizes its objectives through effective data usage. You receive well-founded advice and prioritized activities with regard to the availability and usability of data sources, the quality of customer data, insights from data analysis and the use of data in marketing programs. The output can be used to prioritize marketing plans and can be translated into an operational plan of action. The data maturity model developed by The Data Agency forms the structural basis for an optimal balance between objectives and activities.

The inspiration workshop, the maturity audit and data landscape scan are part of the data strategy. In addition to the strategic advice, you will receive a visualization of the data landscape, a profiling of your customers and website visitors and a report of the data quality.

Inspirational workshops

Workshop to collect ideas, ambitions and bottlenecks related to data application from involved stakeholders. The output of this workshop provides insights of the current situation with our advised next steps and serves as starting point for structural improvement.

 The workshop is ideal for sharing ideas, creating organisational support and exploring improvement potential and ambitions. 

Data landscape quick scan

The data scan quick scan offers insight into which relevant data sources are available, how these can be deployed, which skills are required, which technology and infrastructure is needed and clarifies the coherence of these elements. You receive a visualization of the data landscape, an explanation of the relevant elements and an analysis of bottlenecks and possibilities. This scan answers the question whether data is available and can be used, it sets goal and clarifies data technology, ICT and organizational dependencies that should be taken into account.

The data landscape quick scan output is very useful as a pre-project to develop business cases and validate business assumptions in new marketing investment plans.
