Defending against leak-related damage and downtime

LAIIER solves an $18Bn+ annual problem: damage and downtime caused by liquid leaks in commercial buildings and industrial equipment.

We aim to not only save our customers hundreds of millions of dollars in costs - we also see the opportunity to save millions of gallons of water and millions of tons of CO2 from entering the atmosphere.


LAIIER works closely with commercial property owner-operators, industrial equipment operators, insurers, facilities managers, and system integrators who are invested in building more sustainable, efficient, and safer spaces to work and live. LAIIER's mission is to lower liquid leak-related costs; reduce or eliminate claims; and improve facility performance. Our seamlessly integrated sensor technologies give stakeholders timely and critical insights into the condition and efficiency of their properties.

We are proud to partner with RS Group PLC, which helps manage the manufacture and distribution of our products; and Henkel for its material technology and market expertise.

LAIIER’s team of engineers and designers has decades of experience in printed electronics, IoT, and the design of products that are effective, easy to use, and scalable. Our interdisciplinary approach is the key to our successful innovations and vibrant culture. We are a team of leaders willing to teach, learn, share, and listen. 

Our history

In the early stages of the COVID-19 pandemic in 2020, Bibi, Isabel, and Matt saw a critical challenge: truly scalable remote monitoring of buildings to mitigate water leaks. With buildings left largely unmonitored during lockdowns, Escape of Water events were widespread, with facilities managers and insurers left to pay a high price for the inattention.

Leveraging IP from Bare Conductive, the world’s largest printed electronics prototyping platform (and a company they’d already founded), the team found a scalable solution.

In 2021 we developed a printed sensor IP into a smart “layer” that could send alerts to building owners and operators, even when remotely located. And in 2022, we launched Severn Water Leak Detector, also known as Severn WLD™: the world’s first self-adhesive early water leak detection solution that combines a printed electronics sensor with a hardware device and LoRaWAN communication.

Severn WLD is now deployed with commercial insurance carriers, facilities managers, hospitality venues, and system integrators in the US and UK. We continue to innovate and invest in R&D, and value the feedback we receive from customers and partners.
