Skyfora

Hyper-local atmospheric intelligence for weather-dependent industries

Data & Analytics Growth Series B

Overview

Skyfora is an atmospheric intelligence and weather data platform serving insurers, energy providers, and critical infrastructure operators with hyper-local weather sensing and forecasting. The company, headquartered in Helsinki, Finland, converts existing GNSS (Global Navigation Satellite System) infrastructure and telecom networks into dense real-time weather sensor networks, providing sub-kilometer precision data at minute-level update frequencies. Its insurance-specific solutions cover property, motor, marine, agriculture, and business interruption segments.

The platform delivers weather data through a REST API and an Insight Dashboard, enabling carriers and underwriters to access real-time atmospheric conditions, tropical cyclone nowcasts, and risk forecasts at the local resolution that traditional weather station networks cannot achieve. The core technology, Telecom GNSS Meteorology, processes signal delays from cell towers to produce atmospheric measurements without deploying new hardware -- a patented approach granted in 2024.

Skyfora raised EUR 10.65M+ across pre-seed, Series A (March 2025, EUR 4.15M), and Series B (June 2026, EUR 6.5M) rounds. Investors include Ugly Duckling Ventures, LUMO Labs, Voima Ventures, Eviny Ventures, and the European Innovation Council. The company has collaborated with NOAA -- deploying dropcsondes during Hurricane Nigel in 2023 -- and holds European Space Agency support for its technology development.

Products & Services

GNSS Weather Data API

Real-time atmospheric data integration platform delivering seven key atmospheric variables via REST API, including Zenith Total Delay (ZTD), Precipitable Water Vapour (PWV), and Signal-to-Noise Ratio (SNR). Standard receivers update every 30 seconds; StreamGNSS hardware updates every 1 second. Data is available in JSON and NetCDF-4 formats.

Key Features

Seven atmospheric variables at sub-kilometer resolution
30-second to 1-second update intervals depending on receiver type
JSON and NetCDF-4 output, compatible with Python xarray, MATLAB, and R
Access managed via API key through the Skyfora Portal

Target Users: Meteorologists, data science teams at insurers, weather-dependent industry operators

GNSS Micronets

Dense sensor networks deployed in urban areas and critical regions using proprietary StreamGNSS hardware, providing localized high-resolution atmospheric monitoring for cities, ports, and risk-prone zones where standard telecom infrastructure lacks GNSS coverage.

Key Features

Fills coverage gaps in areas without GNSS-enabled telecom networks
Hyper-local monitoring for ports, urban centers, and exposed infrastructure
Feeds data into the Telecom GNSS Meteorology platform

Target Users: Civil protection agencies, infrastructure operators, carriers underwriting catastrophe exposure

Insight Dashboard

Industry-specific weather visualization platform enabling insurers, energy providers, and critical infrastructure operators to view real-time atmospheric conditions, forecast trends, and local risk patterns.

Key Features

Real-time and forecast atmospheric visualization
Risk pattern overlays for underwriting and claims triage
Designed for non-technical insurance and operations users

Target Users: Underwriters, risk managers, claims teams at carriers and MGAs

Telecom GNSS Meteorology Platform

Core software platform that processes GNSS signal delays from cell tower networks into weather data streams powering AI weather models and numerical weather prediction systems.

Key Features

Patented methodology (granted 2024) for converting telecom infrastructure into weather sensors
Scales commercially for meteorological institutions and forecasting providers
Supports next-generation AI weather model development

Target Users: Meteorological institutions, national weather services, enterprise weather data consumers
