What Skyfora does
Skyfora is a Helsinki-based weather intelligence company that transforms existing GNSS infrastructure — primarily 5G telecom cell towers — into a real-time, high-resolution atmospheric sensing network using patented GNSS meteorology technology and AI-powered 3D atmospheric tomography. The platform reconstructs dense, sub-kilometer resolution atmospheric data from satellite signal delays that are 20-1000× denser than traditional weather station networks, delivering atmospheric variables (Zenith Total Delay, Precipitable Water Vapor, signal-to-noise ratios) with under five minutes of latency and 99.95% pipeline reliability. The company also designs and manufactures its own atmospheric profiling instruments — the StreamSonde 43 dropsonde (80g) and StreamSonde RS radiosonde (32g), claimed as the world's lightest weather sondes — used by NOAA Hurricane Hunters for tropical cyclone reconnaissance.
Skyfora's commercial portfolio spans three layers: (1) data collection via Telecom GNSS Meteorology integrations with telecom operators (deployed with A1, A1 Slovenia, Nokia, and Telia Finland) and proprietary StreamGNSS micronet deployments of 15-50 sensors per site; (2) AI-driven processing and atmospheric tomography producing spatiotemporal forecasts optimized for rainfall and storm prediction; and (3) delivery through a GNSS Weather Data API (REST, JSON/NetCDF-4, updated every 1-30 seconds) and a visual Insight Dashboard for real-time network monitoring. The company sells primarily through direct enterprise sales on a quote-based annual subscription model, complemented by hardware sales and custom managed-services deployments. Target verticals include critical infrastructure (telecom, utilities, data centers), energy (hydro, wind, solar, power trading), urban hubs (airports, ports), defence, insurance, and AI weather model developers.
Skyfora was founded in 2019 and has raised approximately €10.5M total across equity rounds and non-dilutive grants from Ugly Duckling Ventures, Eviny Ventures, LUMO Labs, European Innovation Council Fund, Business Finland, Voima Ventures, and Icebreaker.vc. With 11-50 employees and operations expanding from Europe into the United States, Africa, and the Middle East, Skyfora positions itself as the upstream data layer for next-generation AI weather forecasting, combining in-house atmospheric science expertise with a distribution model that piggybacks on telecom infrastructure.

Skyfora product offering
Product offeringCore offering
Skyfora provides hyper-local, real-time weather intelligence by transforming existing 5G telecom cell towers and proprietary GNSS micronets into a dense atmospheric sensing network. The company sells a GNSS Weather Data API, StreamGNSS micronet hardware, ultra-lightweight StreamSonde dropsondes and radiosondes, and AI-powered atmospheric tomography and forecasting services for enterprise customers. Revenue is earned through API subscriptions, instrument/micronet hardware sales, and custom managed deployments.
Product overview
Skyfora is a weather intelligence platform that transforms existing GNSS infrastructure into a real-time, high-resolution weather-sensing network. The portfolio consists of three core layers: (1) data collection via Telecom GNSS Meteorology (leveraging 5G cell tower receivers) and StreamGNSS Micronets (proprietary antenna networks), complemented by StreamSonde 43 and StreamSonde RS weather instruments; (2) processing and analysis through AI-powered atmospheric tomography and forecasting; (3) delivery via the GNSS Weather Data API and Insight Dashboard visualization tool. The platform provides 7 atmospheric variables including Zenith Total Delay, Precipitable Water Vapor, and satellite metrics with ultra-low latency (<5 minutes).
