Skyfora, a Finland-based company that turns existing telecom and GNSS infrastructure into dense atmospheric sensing networks, has raised €6.5 million in Series A funding. The round was led by Eviny Ventures alongside Ugly Duckling Ventures, LUMO Labs and the EIC Fund. Skyfora’s patented GNSS Meteorology software converts cell towers and 5G base stations into real-time weather sensors that deliver sub-kilometer 3D atmospheric data for AI forecasting and nowcasting. The capital will scale the platform, launch a commercial data API and expand deployments across Europe, the US, Africa and the Middle East.
5G Towers Feed AI Weather Models
The timing aligns with surging demand for dense observational data that current satellite and radar networks cannot supply. Skyfora’s approach reuses millions of existing GNSS receivers in telecom infrastructure via a software update, producing 20–1000 times more measurements than traditional systems with minute-level latency. This directly addresses gaps limiting next-generation AI weather models.
Extreme Weather Data Gaps Cost Billions
The weather information technologies market stood at $9.23 billion in 2025 and is projected to reach $18.92 billion by 2033. Extreme weather events already generate nearly $1 trillion in projected losses, with 62 percent of cities, states and regions reporting significant impacts. Traditional observation networks remain too sparse for the resolution AI models require, leaving critical sectors such as energy, aviation and defense exposed.
Software Layer Replaces New Hardware
Skyfora activates GNSS signals already present in 5G towers to generate real-time humidity, temperature and pressure tomography. The system simultaneously detects GNSS jamming and spoofing, creating a dual-use capability demonstrated at NATO events. Unlike competitors that rely on proprietary satellites or drones, Skyfora requires no new physical infrastructure.
As Fredrik Borgström, CEO of Skyfora, noted:
“We’re turning existing mobile networks into the data layer for next-generation weather forecasting.”
Energy Investor Validates Infrastructure Play
Eviny Ventures, the corporate venture arm of a major Norwegian renewables company, led the round. Its focus on energy transition technologies matches Skyfora’s use cases in power trading, wind and solar operations. The participation of the EIC Fund alongside Nordic VCs signals both European policy support and commercial traction following earlier pilots with Telia in Finland and LMT in Latvia.
Weather Data Market Expands Rapidly
The broader market is growing at roughly 9.4 percent CAGR as AI models and climate resilience needs intensify. Meteomatics raised $22 million for its weather intelligence platform, while larger players such as Spire Global and Tomorrow.io have each raised over $200 million. Skyfora differentiates through zero-capex deployment on existing telecom assets and proven national-scale rollouts validated by NATO.
National Deployments Signal Next Phase
With 100 5G sites already active in Finland for simultaneous weather and jamming detection, Skyfora plans to launch its real-time data API in mid-2026 and extend commercial operations into new regions. Additional senior GNSS and radio occultation scientists were hired in early 2026 to support the expansion.
