INTEREL

What INTEREL does

INTEREL is a Singapore-headquartered smart building technology company founded in 2010 that develops IoT-enabled hardware and software for the hospitality and multi-dwelling unit (MDU) markets. Its core technology is INTEREL OS, a proprietary operating system that runs across the company's device family — most notably the EOS 2 enterprise-grade smart thermostat, the ETERNA metallic keypad, and the FLAT 2 series — and which has received 100+ over-the-air software upgrades since inception. The EOS 2 is engineered as an all-in-one room controller: it combines HVAC control, a built-in IoT hub supporting Zigbee, Bluetooth, 802.15.4, WiFi, and Modbus, and an Environmental Fusion Sensor that monitors temperature, humidity, motion, VOCs, CO and CO2-equivalent levels for occupancy-based energy management.

The company sells an integrated solution stack that includes the EOS for Hospitality energy management system, a Guest Room Management System (GRMS) for lighting, curtains, and guest services, and an MDU smart building platform for multifamily, student, senior, and military housing. INTEREL's value proposition is anchored on an independently audited 35% HVAC energy reduction, bidirectional integrations with the leading PMS, door-lock, workflow, IPTV, and voice-assistant ecosystems, and a 1–3 year payback in high-energy-cost regions. Its product portfolio has been deployed across 500,000+ devices in 45 countries, with named enterprise customers including Marriott, Accor, IHG, Atlantis, Jumeirah, Kempinski, Emaar, and Best Western.

INTEREL generates revenue through hardware sales (thermostats, keypads, controllers), recurring software and cloud services (over-the-air feature upgrades, the EOS App Store, and the INTEREL.io dashboard), and partner enablement through a global system-integrator channel. Pricing is quote-based and multi-year, with the 2024 launch of an Accor-dedicated self-service portal accelerating enterprise deal velocity. The company is private, backed by Jolt Capital SAS (growth equity), and operates regional offices including in Dubai to support Middle East deployments.
