Honeywell makes aerospace technology (cockpit avionics, aircraft engines), building automation (thermostats, fire systems), warehouse automation, and specialty chemicals. Its aerospace segment supplies every commercial aircraft manufacturer. Its Intelligrated warehouse robots are inside Amazon fulfillment centers. Honeywell's breadth across aerospace, buildings, and industrial makes it a barometer for global industrial activity.
Key relationships in depth
Honeywell and Microsoft have a broad enterprise partnership integrating Honeywell's industrial automation, building management, and safety systems with Microsoft Azure IoT Hub, Azure Digital Twins, and Microsoft 365. Honeywell Forge connects to Azure for cloud-based industrial analytics, and Honeywell's building management systems (BMS) for smart buildings use Azure for occupancy analytics and energy optimization. Honeywell is also deploying Microsoft Copilot tools across its 95,000-person workforce for engineering and operations productivity.
Why it matters: Honeywell's 100,000+ customer sites globally generate industrial data that requires hybrid cloud architecture -- processing on-premises for real-time control and in Azure for historical analytics and AI model training. Microsoft's Azure Digital Twins creates virtual models of Honeywell-equipped industrial facilities, enabling predictive maintenance and operational optimization. As Honeywell reorganizes into separate aerospace and automation companies (planned for 2026), both entities will likely maintain Azure as primary cloud infrastructure.
Honeywell and Google Cloud announced a partnership in October 2024 to accelerate autonomous industrial operations using Google's Gemini AI models on Vertex AI combined with Honeywell Forge, Honeywell's IoT platform for industrial facilities. The partnership connects Google AI agents to Honeywell's industrial automation infrastructure across oil and gas facilities, warehouses, airports, and buildings to reduce maintenance costs, improve uptime, and enable autonomous decision-making in industrial processes. First solutions launched to customers in 2025.
Why it matters: Honeywell Forge connects hundreds of thousands of sensors and operational technology (OT) devices across industrial facilities, generating enormous real-time data streams that traditional analytics tools cannot process fast enough to enable real-time autonomous operation. Google's Gemini multimodal AI can interpret sensor data, maintenance records, and operational history simultaneously to predict equipment failures before they occur. Honeywell's CEO has stated that AI will transform industry at scale beginning in 2025, and the Google partnership is central to this strategy.
Honeywell supplies avionics systems, flight management computers, auxiliary power units (APUs), and environmental control systems to Boeing across its entire commercial aircraft portfolio. Honeywell's Primus Epic avionics suite and its APU (which starts aircraft engines without ground power) are installed on the 737 MAX, 767, and 777X programs.
Why it matters: Avionics are among the most regulated and difficult-to-substitute components in aviation. Honeywell's flight management computers are certified to handle specific aircraft performance envelopes and cannot be quickly swapped for competitor systems. The relationship generates recurring aftermarket revenue: every Boeing in service requires Honeywell APU maintenance.
