LONDON, UK — October 21, 2025 — LAIIER, a pioneer in smart leak detection and infrastructure intelligence, has been named to the Cleantech Group’s 2025 Cleantech 50 to Watch, an annual list recognizing early-stage companies delivering transformative innovations for climate resilience and sustainability.
Selected from hundreds of global nominations, the 2025 cohort reflects a new generation of companies tackling overlooked but critical challenges across the built environment, energy, and materials.
“We’re honored to be named to the Cleantech 50 to Watch,” said Matt Johnson, CEO and Co-Founder of LAIIER.
“At LAIIER, we focus on the customers and spaces that have long been underserved by innovation—where leaks go unnoticed, damage is routine, and data is nonexistent. Our mission is to bring intelligence to the places no one is looking, helping our partners prevent losses, reduce emissions, and build more resilient operations.”
The Cleantech 50 to Watch list comes at a time of mounting global complexity—where geopolitical tensions, economic pressures, and climate volatility are disrupting supply chains, insurance markets, and building operations. The companies on this list represent high-impact solutions built for resilience and scale.
LAIIER was recognized for its novel approach to leak detection and predictive maintenance in commercial buildings and industrial facilities—spaces that often fall outside the scope of traditional smart building innovation.
With its Severn WLD™ system and LAIIER Cloud™ platform, LAIIER is equipping facility managers, insurers, and OEMs with the tools to detect and respond to leaks before they become disasters. The company’s printed, adhesive sensors and LoRaWAN® connectivity make deployment simple, scalable, and cost-effective—even in the most space-constrained or high-risk environments.
This sets LAIIER apart from companies focused solely on heavy industrial assets or residential homes. It’s this middle tier—offices, labs, airports, hotels, wind turbines, and data centers—that is most at risk and least served. That’s where LAIIER operates.
According to Cleantech Group, 2025’s most promising cleantech companies are driving forward new markets in:
Energy-efficient compute
AI for physical systems
Consumer goods sustainability
Bio-based crop resilience
Advanced leak detection and smart infrastructure
LAIIER is proud to represent this last category—building solutions that reduce downtime, cut emissions, and transform risk into insight.
