The global 0G Network, powered by Sigfox 0G technology, is a low power wide area network (LPWAN) dedicated to Massive IoT. It is designed to connect devices securely at low cost in the most energy-efficient way.
SIGFOX has raised $147.0M in total across 4 funding rounds.
SIGFOX's investors include Elaia Partners, Founders Future, Lightspeed Venture Partners, Partech Ventures.
Sigfox is a France-based technology company that develops and operates Sigfox 0G technology, a low-power wide-area network (LPWAN) protocol dedicated to massive IoT connectivity.[1][2][4][9] It enables billions of sensors and devices to transmit small, infrequent data packets over long ranges with ultra-low power consumption, serving industries like smart cities, agriculture, utilities, logistics, and industrial monitoring.[1][2][3][7] The network covers over 1 billion people across 70+ countries, supports 14+ million devices, and spans 5+ million km², solving the problem of cost-effective, battery-efficient connectivity for remote or hard-to-reach IoT deployments without needing cellular infrastructure or frequent recharges.[3][4][5] Sigfox targets businesses digitizing field operations, offering scalability through a subscription model where national operators handle base stations and cloud services.[1][5]
Sigfox was founded in 2009 (or 2010 per some sources) by two French entrepreneurs in France, with the mission to launch a global IoT network under the motto “Make Things Come Alive.”[5][7][9] The idea emerged to create a proprietary, independent LPWAN technology for machine-to-machine (M2M) and IoT applications, distinct from cellular networks, focusing on simplicity for low-data devices.[2][6][7] Early traction came from deploying base stations via national operators who license the technology, leading to rapid global expansion—now in 70+ countries with 6.7–14+ million connected units across industries like energy, security, and smart agriculture.[4][5][7] Pivotal moments include securing cloud-hosted infrastructure in France with Trusted Platform Module security and growing to cover 1.3 billion people, proving viability for scalable, low-overhead IoT.[3][5]
Sigfox stands out in the crowded LPWAN space through these key advantages:
| Feature | Sigfox Advantage | Comparison to Cellular IoT |
|---|---|---|
| Data Payload | Small/infrequent (best for sensors) | Handles high-throughput apps |
| Power Use | Years on battery | Frequent charging needed |
| Cost | Low subscriptions | Higher data fees |
| Coverage | Wide-area, low-infra | Dense but expensive gateways |
[1][2][5]
Sigfox rides the massive IoT trend, connecting the physical world to the cloud amid exploding demand for sensors in smart cities, agriculture, and Industry 4.0, where 50+ billion devices are projected by 2030.[1][3][4] Timing is ideal as 5G and other LPWANs (e.g., LoRaWAN, NB-IoT) complement rather than compete—Sigfox excels in low-data, ultra-efficient niches like remote utilities or soil monitoring, filling gaps in cellular coverage.[2][4][7] Market forces favoring it include rising sustainability needs (low-energy ops reduce emissions), cost pressures on enterprises avoiding custom networks, and global operator partnerships enabling borderless scalability.[1][5] It influences the ecosystem by standardizing Massive IoT, enabling operators to monetize infrastructure and fostering developer communities for plug-and-play sensors, thus accelerating IoT adoption in underserved areas.[3][8]
Sigfox is poised to deepen its 0G leadership in Massive IoT as edge computing and AI-driven analytics demand even leaner connectivity, potentially expanding to 20+ million devices via new operator deals and hybrid 0G/5G integrations.[4][9] Trends like green IoT and smart infrastructure (e.g., carbon tracking, predictive maintenance) will propel growth, especially in emerging markets with rural coverage needs.[1][2] Its influence may evolve toward ecosystem orchestration, licensing 0G tech more broadly while fending off open alternatives through cost and reliability edges—positioning it as the go-to for "whisper networks" that make trillions of silent sensors come alive.[6][8] This cements Sigfox's role from niche innovator to global IoT backbone.
SIGFOX has raised $147.0M across 4 funding rounds. Most recently, it raised $110.0M Series D in February 2015.
