We build live, data-driven sites like this one
This archive is our own work, built from openly available data — the NOAA best-track records, the replay engine, the wind-field rendering and the map tiles served from our own servers in the European Union. If your business generates data — measurements, machines, orders, customers — we are happy to turn it into a clear, interactive interface.
But this is not all we build:
- online shops and websites, with a design of your own
- SaaS products and ERP systems
- mobile apps for Android and iPhone
- data collection, automation and map-based visualization
Or anything else that can be programmed — just get in touch.
