What EpiSensor does

EpiSensor is a privately-held Irish industrial IoT infrastructure company, founded circa 2007-2008 by CEO Brendan Carroll and headquartered in Limerick, Ireland. The company designs and manufactures a complete stack of wireless sensors, industrial gateways, and management software purpose-built for energy monitoring and demand response in commercial, industrial, and utility environments. Its hardware portfolio includes the ZEM wireless three-phase electricity monitors (up to 4000A), ZDR demand response controllers, environmental sensors (temperature, humidity, CO2, pressure, air quality), protocol interfaces (ZMB Modbus, ZHM M-Bus), and wireless switches and range extenders; gateways (NGR-30-3, NGR-30-5, ZGW-10) are industrial embedded computers supporting ZigBee, Wi-Fi, Bluetooth, 4G cellular, LoRa, GPS, CANbus, and RS-485. Software consists of Edge, a visual programming environment for distributed energy resource (DER) management, and Core, an enterprise-class device management platform operating behind customer firewalls.

EpiSensor operates a channel-partner-first go-to-market model, selling through demand response aggregators (Enel X), energy management software firms (CoolPlanet, Spacewell Energy/Dexma, EnergyCAP, MRI Software), system integrators (Capula, ETS, M-Four), and tier-1 utilities (Veolia, Siemens). Direct enterprise sales support large custom deployments. Revenue is generated through one-time hardware sales, software licensing/subscriptions, and tiered annual support contracts priced per deployed node (€299/year for up to 5 nodes, scaling to €1,188/year for 51-100 nodes, with custom pricing above 100 nodes). The company serves approximately 970 customers across 20 countries with over 25,000 devices deployed, with reference end-customers including Microsoft, ESB, Dublin Airport Authority, Veolia, Foyle Food Group, 3Arena, and Inteliigistics. Strategic projects include a 2022 demand response deployment at Microsoft data centers in Dublin with Enel X and a 2024 renewable energy tokenization pilot at Grouselodge Wind Park with ESB, Dell Technologies, and VMware. The company is founder-owned, has raised approximately $3.3M in cumulative disclosed funding (predominantly Irish state and seed capital), and operates with an 11-50 headcount under Brendan Carroll (CEO), John Ginnane (COO), and Cristina Coffey (Chief Strategy Officer).
