  1. Hi Kalnins,

    Have you seen the Allianz – Smart Fire Protection Contest?

    Send me an email if you have any questions

    Allianz, one of the largest insurance companies worldwide, has identified a lack of fire protection measures in small and medium-sized enterprises (SMEs) in the textile industry. The majority of SMEs are only elementarily protected against fire (smoke detector alarm, fire extinguisher), even though the owners are aware of how severe fire damages can be. This is mostly due to a high cost for effective equipment (high-pressure sprinklers, etc.), as well as time-consuming regular maintenance needed.

    To reduce the high costs linked to fire damages in textile SMEs, Allianz aims to develop a new and effective fire protection device that would be cheap to install and would require little to no maintenance. To take part in this challenging project, submit your solutions / concepts and co-develop the product with Allianz!

    The 3 winners will be invited to further develop their concepts, together with the Allianz core team and HYVE innovation consultants. Open Worldwide Closes on 8th July 2018 1st Place: 8 000 € 2nd Place: 3 000 € 3rd Place: 1 000 € Most Valuable Participant: 1 000 € Most innovative concept: 500 € Most advanced design/concept: 500 €
