Market segments focus
Outdoor enthusiast (using 2+ weather apps)Urban commuter, traveler, wind sports
ProfessionalsAgriculture, energy, retail, logistics, insurance, tourism, outdoor events
Meteorological agenciesData validation, competition analysis
Weather affects: Productivity - Safety – Leisure(…and 1/3 of the worldwide economy)
WxM is Skroutz for weather
● Tracks the accuracy of weather forecasts
● Delivers the most reliable one per location
Starting with a simple app
