Leading in Connected Commerce

The way into the digital future comes with changes and new possibilities for you and your company. But the transformation also brings its challenges. It is therefore essential for us to know all the variables of connected commerce across all businesses, understand them, and network them in the best possible manner for the benefit of our customers. This requires holistic, flexible, and seamlessly integrated strategies and processes.


On the journey through the dense digital jungle we are accompanied by a reliable companion who keeps us on track: our customers' needs.

We are driven by our passion for using innovative ideas to help businesses, simplifying their business processes, reacting to changes flexibly, and making everyday life less complicated for people and more comfortable on a permanent basis. Customer-centricity is not just a buzzword for us, it is our top commandment. In all our strategy and concept considerations, we always place the needs of our customers ahead of everything else and keep them in mind during the implementation phase.


Networking people with one another: We bring people together – not to mention that never before have people been so closely connected to one another as they are today. This is clearly reflected in social communities. We can access the most diverse information whenever we want. This also means that never before have we been as closely connected to brands and companies as today.


Making good use of connections: We bring customers and companies together and generate added value for both sides. We understand what is important to our customers and orientate ourselves by their needs – we share this expertise with our partners and create intelligent solutions for business processes.


Accessibility: We create experiences – at any time, at any place and precisely then when the customer wants it. Our insight into human nature, empathy and professional expertise put us in a position to be able to develop a holistic strategy for unique experiences and implement these. We achieve this in a customer-focused approach and via all touchpoints.


Getting connected in a meaningful way: We reach people on their level and bring them aboard – thereby assisting them with improving their everyday life, simplifying it or embellishing it. Integrated solutions and interfaced devices allow us to facilitate seamless transitioning for an eventful customer journey. We will help you to take advantage of the synergies available on the “Internet of Things”.


Using information: We use information in the best interests of the customer and the business – because only someone who understands the data, can generate value. This pertains to user, as well as shopping behaviour, also to information obtained from industrial plants or buildings. Purchasing processes and internal business processes thus enter the next level.

Connected commerce is an ever-changing process. Both the type of communication and the employed technologies change more and more rapidly. Thus, we not only find the best combination of all digital possibilities individually for each company, but also ensure that we are able to react smoothly to future developments and quickly integrate innovative solutions. As digital lead agency, we provide a variety of services for this.

Interdisciplinary and agile - our connected teams

We benefit and learn from each other, every day and in direct exchange. For this reason, we work in interdisciplinary teams of strategists, designers and developers to unify all our knowledge and skills to a common goal: the best possible solution for our customers.

Facts & figures

We are equipped with a special capital - a strong team of highly motivated and qualified employees. With our entire competence we are always within reach - in Bremen, Hamburg, Berlin and Munich - and also directly at your place.

The picture shows three key figures of hmmh. 6 locations: Bremen, Hamburg, Berlin, Munich, Trivandrum and Wroclaw. Employees: More than 340 and 26 million euros in sales in fiscal year 2021/2022.
