The world’s leading trade fair for HVAC + Water puts the industry's newcomers in the spotlight.

Pioneering spirit meets experience: the Start-up@ISH 2023 programme

Hotspot Energy

For the third time in a row, the VdZ – the German Association for Energy Efficiency in Building Services, will present its Start-up@ISH Area in the exhibition halls of the Main metropolis.

From 13 to 17 March, the Start-up Area in Hall 11 will be a meeting place for undisguised pioneering spirit and entrepreneurial experience. At the start-ups' exhibition stands or during entertaining networking events, ideas will be exchanged and new approaches discussed, potentials for possible cooperation explored and the course set for breaking new ground together in the fields of building technology, sanitation and digital services for skilled trades businesses.

At the Start-up@ISH Area in Hall 11, up to 20 start-ups will present their new innovations during the entire duration of the fair. Some of them will be present on all five days of the fair, others will exhibit exclusively for one day.

The Start-up@ISH Area is the hub for promising building technology start-ups. Here, young founders can inspire established companies with their ideas. At the same time, our area serves as a meeting and inspiration space for industry players who – in line with the Building New Energy approach – are in search of new energy. At the Area, varied, short event formats will ensure optimal exchange and networking. In addition, we will bring the topic of start-ups and innovations to the large associations' stage "Hotspot Energy" in the foyer of Hall 12, where start-ups will present their innovations in the form of pitches – always at lunchtime (except on Thursdays). Start-up impulses are another item on the programme. Each day, experts will illuminate a start-up trend topic in entertaining lectures.
