A profile of Sigfox, the French startup building a global communications network for Internet of Things devices

Context & Ripple Effects
This VentureBeat profile by Chris O'Brien catches Sigfox at its peak momentum: months after the $160M Series E at a reported $637M valuation with around 10M devices registered, a planned expansion to 100 U.S. cities, and a consumer-facing partnership bringing Atari into connected devices. The pitch was a dedicated, low-power global network purpose-built for IoT rather than piggybacking on cellular carriers.
Read against the full arc, the profile documents the top of the curve: despite raising over $300M in total, Sigfox filed for bankruptcy in January 2022, citing slow sales and supply chain issues — making this piece a record of how the dedicated-IoT-network thesis looked when capital was still flowing into it.
First-order effects
- At the time of writing, Sigfox is deploying its own infrastructure city by city and signing device-maker partners like Atari, betting that owning the network layer lets it sell connectivity as a service to hardware companies.
Second-order effects
- The bankruptcy filing five years later shows the model's weakness: a proprietary network needs massive device volume to cover buildout costs, and slow sales left Sigfox unable to sustain the capex its 2016 valuation implied.
Third-order effects
- If the pattern holds, single-purpose IoT networks struggle to survive as standalone businesses, pushing low-power connectivity toward models bundled with existing infrastructure or owned by players with other revenue to subsidize the network.
The trend: Dedicated low-power IoT networks attracted hundreds of millions in venture capital on the promise of a global footprint, but device volumes never caught up to the cost of running standalone infrastructure.
