About KIWI

We’re convinced:
the key to the future isn’t a key!

Digital access rights are slowly replacing keys. Access will become easier and more secure than ever before. Opening doors will become a seamless process – no need to think about it, no worries, no physical objects – with security, convenience and fun. That’s what we believe in and work on at KIWI every single day.

What’s important to us

Like many innovations, the idea for KIWI came from privately solving a problem. KIWI is now a product that makes day-to-day life easier for lots of people and offers companies real added value. And we’re proud of that.

Experience & satisfaction

When developing our products, user experience is very important to us. Ease of use and a high level of convenience are our focal points.

Security & protection

Security and data protection are the cornerstones to our products. The infrastructure was designed together with white hat hackers and is regularly tested and further developed.

Courage & passion

We make things shine. As a team, we are united by an innovative spirit and the joy we take in technology. We dare to question and change the status quo time and again.

About KIWI – from newcomer to market leader

KIWI has been on the market since 2014 and quickly established itself as the market leader for digital locking systems in the housing industry. KIWI has successfully left the critical start-up phase behind. Today over 100,000 residential units are connected to KIWI’s infrastructure.

KIWI was able to win over well-known partners from the very beginning – Allianz, Aareon, ALBA, Berlin Fire Brigade, Deutsche Post and Schindler are important collaborative partners of KIWI, who consider the KIWI system to be very secure and fit for the future.

Since 2017, Deutsche Wohnen has been an important strategic investor on KIWI’s side, which will gradually equip its entire portfolio of 160,000 residential units with the KIWI system.

Europe’s largest door manufacturer for high-rise buildings was added in 2018 with the second strategic investor, Arbonia AG. The Swiss company asked what a building door should look like within the context of digitalisation. In the end, anything to do with digital access was the answer. Before investing, Arbonia AG engaged with numerous locking system manufacturers and put them through their paces. They ultimately chose KIWI. Both investors are interested in KIWI’s long-term success.

We are proud that we have over 600 customers from the housing industry. These include:
