Microsoft Azure IoT Hub and Azure Digital Twins underpin $10B+ in cloud IoT platform revenue, connecting over 1 billion devices for customers including Starbucks, Rolls-Royce, and Siemens. The 2025 integration of Azure IoT with Copilot AI enables natural-language querying of device telemetry at scale. Azure IoT Central offers no-code device management for SMEs, while Azure Sphere provides end-to-end OS-level security for microcontrollers in mission-critical deployments.

AWS IoT Greengrass extends cloud compute, AI inference, and data sync to edge devices running in facilities without reliable internet, powering smart factories, autonomous robots, and connected vehicles. AWS IoT Core processes trillions of device messages per year across customers in 190 countries. The 2025 launch of AWS IoT ExpressLink chips lowered the barrier to entry for hardware makers connecting products to AWS in under 30 minutes.

Qualcomm IoT segment generates $8B+ revenue with 100B+ connected chips shipped across consumer electronics, industrial gateways, and automotive platforms. Its Snapdragon IoT series and QCS6490 platform deliver on-device AI inference for always-on vision and voice applications. Qualcomm's 2025 partnership with Microsoft brings Copilot+ AI capabilities directly to IoT edge hardware, targeting smart retail, healthcare monitoring, and factory safety applications.

Texas Instruments dominates embedded IoT with its CC32xx Wi-Fi MCU series and SimpleLink platform, generating $5B+ in IoT/embedded segment revenue. Its MSP430 and AM64x processors power billions of smart meters, industrial sensors, and medical monitors globally. TI's 2025 E3 initiative expanded its ultra-low-power MCU roadmap for battery-less IoT devices harvesting ambient energy, extending sensor deployment into previously unreachable industrial environments.

PTC ThingWorx is the leading industrial IoT application platform with $2.1B in annual revenue and 1,700+ enterprise clients including Bosch, Caterpillar, and Michelin. Its Vuforia AR integration lets factory workers overlay live sensor data on machinery via smart glasses. PTC's 2025 acquisition of ServiceMax for $1.46B added field service IoT analytics, enabling predictive maintenance workflows that reduce unplanned downtime by 50%+ for industrial customers.

Samsara IPO'd on NYSE in 2021 and crossed $1B+ in annualized revenue in 2024, providing fleet telematics, industrial IoT, and video safety solutions to 20,000+ customers including the US federal government and Amazon Logistics. Its AI Dash Cams detect unsafe driving behavior in real-time, cutting accident rates by 30%+. In 2025, Samsara launched its Connected Operations Cloud to unify vehicle, equipment, and site sensor data into a single AI-powered operations platform.

Twilio IoT enables programmable SIM-based cellular connectivity for IoT devices across 180+ countries, generating $1.86B in total platform revenue. Its Super SIM product provides a single global SIM that dynamically switches between 450+ carrier networks, eliminating roaming complexity for connected product manufacturers. In 2025, Twilio launched AI-powered anomaly detection for IoT device fleets, automatically identifying compromised or malfunctioning devices before they impact operations.

Particle Industries is a full-stack IoT SaaS platform valued at $750M+, offering hardware modules, device OS, cellular connectivity, and a cloud device management layer used by 250,000+ developers and enterprises. Its B-Series SoM and Tracker Edge firmware power asset tracking and environmental monitoring at scale. In 2026, Particle launched its Fleet Intelligence platform using ML anomaly detection to predict hardware failures 72 hours before they occur across connected product fleets.

Google Cloud IoT solutions (formerly Google Cloud IoT Core, pivoted to ecosystem partners in 2023) continue to power smart building, energy grid, and manufacturing deployments via Vertex AI at the edge and BigQuery IoT analytics. Google's Nest ecosystem connects 100M+ smart home devices, and its AI-powered energy optimization tools reduce building HVAC costs by 30%+ for commercial clients. The 2025 Google Distributed Cloud Edge brought AI inference to air-gapped industrial facilities.
