- Helsinki-based Skyfora has raised €6.5M to scale its platform that converts existing telecom infrastructure into a real-time atmospheric sensing network.
- The round includes Eviny Ventures, Ugly Duckling Ventures, LUMO Labs, and the EIC Fund, alongside non-dilutive support from Business Finland.
- The funding will accelerate commercial expansion across Europe, the US, and the Middle East, and strengthen partnerships with telecom operators and AI weather-forecasting platforms.
There is a big data gap in global weather forecasting. Satellites monitor the upper atmosphere, while ground stations only cover areas where people live. Large parts of the atmosphere, especially the layer above cities, coastlines, mountains, and oceans, remain largely unmeasured. Updates are infrequent, and the data is insufficiently detailed for modern AI models.
Skyfora, founded in 2019 by Fredrik Borgström and Kim Kaisti, believes the solution is already in place at millions of sites worldwide. It simply has not been activated yet.
The Helsinki-based weather intelligence company has raised €6.5 million to expand its platform, which turns GNSS receivers in telecom towers into sensors that continuously measure the atmosphere. This gives real-time updates on humidity, temperature, and pressure from the ground up, every minute, without needing new hardware at any site.
Investors in this round are Eviny Ventures, Ugly Duckling Ventures, LUMO Labs, and the EIC Fund. Business Finland also provided non-dilutive funding.
The atmospheric data gap that AI cannot solve alone
Skyfora uses the delay in GNSS signals as they travel from satellites to receivers. Water vapour in the atmosphere bends and slows these signals in measurable ways.
“We’re turning existing mobile networks into the data layer for next-generation weather forecasting and climate intelligence,” says Borgström.
Every telecom tower with a GNSS timing receiver, originally installed to keep networks in sync, already picks up this signal. Skyfora’s software converts atmospheric delay into real-time profiles of precipitable water vapour.
Competitors include Tomorrow.io, which raised $175 million in February 2026 to launch a satellite network for weather data, and WindBorne Systems, which raised $15 million to grow its long-duration balloon network. In Finland, Vaisala is the established leader in atmospheric sensing and measurement.
What sets Skyfora apart is its data. If its telecom sensing network grows worldwide, it could become key infrastructure for AI weather models and offer a more sustainable business model than selling forecasts directly.
Strategic investment from the energy sector
One key investor in this round is Eviny Ventures, which is the venture arm of the Norwegian energy group Eviny.
Energy companies are some of the most affected by the weather. Wind and solar power, grid balancing, and managing hydropower reservoirs all depend on forecasts that are not accurate enough for their needs. The World Bank estimates that better global weather monitoring could help weather-affected industries by about €160 billion.
“Fredrik and the team at Skyfora turn weather data into something the energy system can actually act on. Skyfora addresses a real operational problem for the Eviny group, and that’s the starting point for every investment we make,” says Lars Jacob Sjaastad, investment manager at Eviny Ventures.
Ugly Duckling Ventures, which led the previous €4 million round in March 2025, has invested again.
“When we first invested in Skyfora, there was technical risk in the feasibility of rolling it out in the ecosystem. With the technical risk significantly reduced, the opportunity now lies in commercialising a truly unique atmospheric data platform,” says Andreas Green Rasmussen, GP at Ugly Duckling Ventures.
LUMO Labs, which has supported the company for over 18 months, remains committed to the strength of Skyfora’s data. “They are building a unique advantage through proprietary atmospheric data and are on a path to secure the world’s largest real-time GNSS weather data assets,” notes Linn-Cecilie Linnemann, partner at LUMO Labs.
How Skyfora will use the funds
The new funding will help Skyfora roll out its services in Europe, the United States, and the Middle East. It will also improve how the company works with telecom operators and AI weather-forecasting platforms that require more data.
Skyfora has finished its first live deployment of Telecom GNSS Meteorology in Europe and won the Deloitte Innovation Accelerator Ventures for Impact award in 2025. The company has now raised about €11 million in total, including grants and equity rounds.
