What LAIIER does

LAIIER is a London-headquartered IoT company, founded in 2021, that builds commercial water leak detection systems. Its core product, the Severn WLD, is a smart water leak detector built around patented printed sensor technology with a segmented 12-zone electrode array capable of detecting as little as 0.1 mL of water while suppressing false positives through a per-device dynamic threshold calibration. The device transmits data over LoRaWAN (up to 2 km range, OTAA-encrypted), runs on a 6-year battery, installs via peel-and-stick, and carries an IP65 enclosure rating suited to plant rooms, HVAC closets, and risers. A secondary US office in Denver supports North American operations.

The company sells two integrated components: the Severn WLD hardware and the LAIIER Cloud platform, which provides real-time alerts via dashboard, email, or SMS, pattern analytics, and integration with existing building management systems. The company offers two commercial models: a one-time hardware purchase plus ongoing monitoring (CAPEX) and a Hardware-as-a-Service monthly subscription (OPEX). Both include 24/7 monitoring, unlimited cloud users, and dedicated support, with pricing handled on a quote basis.

LAIIER pursues an enterprise field-sales go-to-market targeting commercial real estate owner-operators and REITs, insurance carriers and brokers, facilities managers, and adjacent verticals including life sciences, multifamily, retail, airports, student housing, hospitality, and construction. Named reference customers include Rentokil Initial, Comcast, AXA XL, Cadillac Fairview, Grosvenor, Henkel, and Cox Engineering. The company is led by co-founders Matt Johnson (CEO), Bibi Nelson (COO), and Isabel Lizardi (CCO), is funded by a January 2025 $4M seed extension led by Closed Loop Partners' Ventures Group with seven other funds, and operates with a sub-50-person headcount from London and Denver.

Core offering

LAIIER sells commercial water leak detection hardware (Severn WLD smart sensors with patented printed sensor technology and LoRaWAN connectivity) and a cloud monitoring platform (LAIIER Cloud) that delivers real-time leak alerts, analytics, and building management system integration. The solution is targeted at real estate owner-operators, REITs, insurance carriers, and facilities management companies seeking early detection of small water leaks to minimize property damage and unplanned downtime.

Product overview

LAIIER provides a commercial water leak detection solution consisting of two integrated products: Severn WLD™ (the hardware sensor) and LAIIER Cloud™ (the cloud monitoring platform). The Severn WLD sensors use printed sensor technology to detect water leaks of even the smallest size while minimizing false positives, and transmit data via LoRaWAN to the LAIIER Cloud platform where facility managers receive real-time alerts and analytics.

Functional benefit

Brands

• Severn WLD: State-of-the-art smart water leak detector utilizing innovative printed sensor technology that detects water leaks of even the smallest size while avoiding false positives. Features 12 detection zones, 883mm sensor length, LoRaWAN connectivity with up to 2km range, 6-year battery life, and IP65 enclosure rating.
• LAIIER Cloud

Products and services

• Severn WLD A smart water leak detector hardware sensor using patented printed sensor technology with 12 segmented detection zones capable of identifying as little as 0.1 mL of water. The peel-and-stick device runs on a 6-year battery, communicates over LoRaWAN with up to 2 km range and OTAA end-to-end encryption, and is built into an IP65 enclosure rated for -20°C to 60°C operation. It is sold to commercial real estate owners, insurance carriers, and facilities managers for early leak detection across HVAC, plumbing, expansion tanks, equipment rooms, restrooms, kitchens, and other water-risk zones.
• LAIIER Cloud A centralized cloud-based monitoring and analytics platform that ingests data from Severn WLD sensors and provides real-time leak alerts via dashboard, email, or SMS, along with detailed analytics to identify leak patterns and prevent future incidents. The platform supports unlimited cloud users, integrates with existing building management systems, and is included in both the OPEX subscription and CAPEX+monitoring commercial offerings for enterprise customers.

• Eddy Smart Home Solutions: Eddy Smart Home Solutions offers smart water leak detection and shutoff solutions for residential and light commercial customers. Notably, it hired LAIIER's former VP of Sales in February 2026, indicating direct competitive overlap in smart water leak detection.
• Leakomatic: Leakomatic provides automated water leak detection systems for residential and commercial properties, with continuous monitoring and automatic shutoff. It competes with LAIIER in the smart leak detection category targeting property owners and facility managers.
• FloLogic: FloLogic manufactures intelligent leak detection and automatic shutoff systems for residential and light commercial buildings. Its combination of leak sensing and automatic water shutoff parallels LAIIER's commercial building focus.
• Phyn: Phyn offers smart water monitoring with leak detection and water-use analytics under a joint venture between Belkin and Badger Meter. While more residential-weighted, its smart water sensor + analytics model overlaps with LAIIER's hardware-plus-cloud approach.
• WaterSignal: WaterSignal provides water leak detection and submetering solutions for commercial real estate, multifamily housing, and student housing. Its customer segments (multifamily, CRE, student housing) directly overlap with several of LAIIER's priority verticals.

Regional players

• HWM-Water: HWM-Water is a UK-based provider of water network monitoring, leak detection, and pressure/flow logging equipment, part of the Halma plc group. While primarily serving water utilities rather than buildings, its leak detection technology and UK base make it a comparable regional player to LAIIER.

Broad incumbents

• Honeywell Building Technologies: Honeywell's building technologies division provides integrated building management systems including environmental and water monitoring capabilities. As a broad incumbent with extensive commercial real estate relationships, it could bundle water leak detection into larger BMS contracts as competition for LAIIER.
