CUMULUS

What CUMULUS does

Cumulus (operating as Cumulus City) is a Spain-based, private IoT platform company founded in 2016 and headquartered in Vila-real, Castellón. It sells a vertically integrated hardware-and-software stack comprising roughly twelve proprietary sensor types — including ultrasonic waste-bin fill-level sensors, parking sensors, lighting/air-quality/noise/weather sensors, multi-gas environmental sensors, water-quality and water-level sensors, soil-moisture sensors, and high-speed water-usage data sensors — connected through proprietary HUB and Gateway devices to a central cloud-based Plataforma that aggregates, visualizes, and alarms on real-time and historical data. Wireless connectivity is delivered across multiple protocols: Wi-Fi, LoRa (claimed up to 22 km), ZigBee, Sigfox, and Bluetooth, enabling interoperability with third-party devices (most recently demonstrated by a March 2026 integration with Megger electrical testing tools for connected insulation resistance testing). The company also operates a separate Cloud Cost Diagnostic service, with a $1,000 fee waived for African startups.

Cumulus serves four customer segments, primarily Spanish Municipal Governments and Smart City Initiatives (the lead segment, addressing waste, parking, lighting, air-quality, and noise use cases), with secondary segments in Industrial Operations, Agriculture (soil moisture, irrigation, fertilizer optimization), and African startups (cloud cost optimization). The business model combines hardware sales (proprietary sensors, gateways, hubs) with subscription-based platform/software services for data visualization, historical analysis, sensor mapping, and alarm/notification management. Go-to-market is sales-led and direct, anchored at the Vila-real headquarters with phone and email channels, supplemented by a Spanish-language website, social media presence (Facebook, X, Instagram), and RSS content. There are no disclosed named customer logos, no published pricing, no disclosed funding rounds, and no published revenue figures.

The company competes in a fragmented European IoT-for-cities market. Its differentiation rests on (1) the breadth of its in-house sensor portfolio spanning three verticals, (2) multi-protocol interoperability that allows the platform to integrate third-party devices, and (3) direct relationships with Spanish municipal buyers. Constraints include geographic concentration in Spain, a small employee base (11–50), absence of disclosed customer logos or revenue, and no evidence of proprietary AI/ML depth beyond a platform-level 'AI and Bluetooth' positioning claim in the Megger partnership announcement.

Revenue model

1. IoT Hardware and Sensor Sales: Cumulus sells proprietary sensors and devices (waste sensors, parking sensors, environmental sensors, gateways, hubs) to smart city, industrial, and agricultural clients. The revenue is generated from the sale of physical IoT devices along with the associated software platform access.
2. IoT Platform and Software Services: The company provides a cloud-based platform for data visualization, historical analysis, sensor mapping, and alarm/notification management. This appears to be a recurring subscription-based model for accessing the platform and receiving real-time data services.

Core offering

CUMULUS designs, manufactures, and sells a proprietary IoT sensor ecosystem (ultrasonic waste sensors, parking, lighting, air quality, noise, weather, soil moisture, water quality, water level, and multi-gas environmental sensors) along with HUB and Gateway communication devices, all unified through a cloud-based Plataforma for real-time monitoring, historical analysis, sensor mapping, and customizable alarms. The offering is delivered to municipal, industrial, and agricultural customers as bundled hardware-plus-software Smart City, Industry, and Agriculture solutions, supplemented by a separate cloud cost diagnostic service for AWS-using startups.

Product overview

Cumulus is an IoT platform company comprising two distinct operations: Cumulus City, a Smart City, industry, and agriculture solutions provider based in Spain, and a separate cloud cost optimization service. Cumulus City offers a modular IoT ecosystem centered on its central Plataforma that aggregates data from a comprehensive range of wireless sensors—waste fill-level sensors, parking sensors, lighting sensors, air quality sensors, noise sensors, weather stations, environmental sensors (multi-gas detection with fire alerts), water quality sensors, water level sensors, and soil moisture sensors. These devices communicate via multiple wireless protocols including Wi-Fi, LoRa (up to 22km range), ZigBee, Sigfox, and Bluetooth. The system uses HUB devices for multi-device aggregation and Gateway devices for protocol unification. The platform provides historical analysis, real-time mapping, customizable alarms and notifications, and a customizable data dashboard accessible from any internet-connected device. The separate Cumulus cloud division offers cloud cost diagnostics for enterprises, with AWS-focused optimization services including a waived diagnostic fee for African startups.
