In recent years, the strategies and programs of the Helsinki region have put a lot emphasis on the wellbeing of city residents. In order to support this, new innovative solutions, products and services related to well-being, exercise and health are needed. At the same time, companies developing these types of services and products have longed for concrete piloting opportunities in authentic urban environments and closer cooperation with cities. Traditionally, companies in these fields cooperate or seek cooperation with e.g. hospitals or health care organizations. However, no concrete opportunities for utilizing urban environments as a piloting platform for the companies’ solutions in this theme have been available thus far (even though cities have been active in developing testbed activities within other industry sectors, such as smart mobility). Now, in the KauKo project, new or planned new areas (Laurea's new campus area in Espoo's Kivenlahti as a pilot) and old urban environments (Helsinki's urban renewal areas) are combined in a new way as piloting platforms for solution developments that promote wellbeing, health and exercise. The aim is to enhance innovative solutions that, on the one hand, open new markets for companies and thus improve their competitiveness, and on the other hand, bring forward innovative new services, products and physical solutions to urban environments, increasing the wellbeing and health of locals in the long term. These solutions include, for example, urban spaces that promote exercising and spending time outdoors, solutions that encourage play, innovations related to safe walking and pleasant routes, mobile health measurement solutions, and solutions that help utilise the full potential of nature in well-being. The preparation of the project uncovered that regional-level, multi-stakeholder cooperation is necessary in the development of the piloting platform model of urban environments. There is a need for more cooperation both within cities and between divisions in different cities. The project focuses in particular on bringing together companies of different sizes, RDI operators, different city divisions and units, as well as the end users of services, i.e. residents. Therefore, an important part of the project is the development of a joint capital region ecosystem; ‘HYTE in urban environments’. The ecosystem will facilitate efficient cross-sectoral information transfer and synergies, boost innovative thinking, increase cities’ awareness of innovative solutions, and build valuable business momentum for companies. These activities will help achieve the core goal and long-term impact of the project: strengthening the competitiveness and vitality of companies working in the well-being sector. The project implements the Ecosystem Agreement of the capital region and its objective on wellbeing and health technology, as well as the ERDF Special Objective 1.3. by strengthening the competitiveness of companies in the region, developing an innovative piloting platform model and building a functioning, new ecosystem around the topic. The innovative solutions developed in the project are also aligned with the principles of sustainable development.
