4.7(7 reviews)Raising Potentials
We cannot predict the future - but we make it possible. Future viability is the most important characteristic a company can have today. In an ever-changing world, the adaptable survive. Those who react nimbly and flexibly to new influences. Those who recognize and anticipate trends. Survival of the fittest. The Darwinism of companies. Today's "hot shit" is already yesterday's news tomorrow. That's why keeen orchestrates the disciplines of marketing, technology, and experience design into overarching added values. Of course, not everyone plays the same tune, but the result is more than the sum of its parts. This is how we unlock our clients' potential for the future and enrich the lives of millions of people with our work. We believe that truly good digital products can only be created when the user is addressed holistically. Three essential factors play a role here: The head decides rationally about performance. Technology must work, facts must be right. We build the technological platforms that carry brands. As a TYPO3 Gold Member and Shopware Business Partner, we are a reliable, competent contact for digital ecosystems, websites, and e-commerce development. Marketing stages the authentic appearance of a brand or product. We develop the emotional appeal, message, and tonality, and ensure consistent positioning in the market. A user experience that makes you want more is intuitive to use and visually appealing. We design the user experience that excites people.10 works in Web ApplicationLocated in Berlin, Germany (+2)From €20,000 for Web ApplicationWorked in Household Products (+9)Speaks German, English11-50 membersShopboostr
