A few words about Cobuilder


It’s all about data. Fit-for-purpose and accurate product data improves quality of service, time to market and reduces time, cost and environmental footprint


• A platform that can help you exploit the potential of your product data

• Solutions for structuring data according to applicable local and international standards

• i.e. standardizing product data currently stored in PDF-files, or internal systems like PIM, DAM and ERP’s

• The solutions integrates with your existing IT infrastructure (via API’s) and ensure future-proof data structures through the use of Data Templates

• A proven step-by-step implementation process

o assessing savings potential

o Setting up (or adjusting) a digital strategy

o Implementing a Proof of Concept

o Full implementation, country by country
