The company was supported at ESA Business Incubation Centre UK - ESA BIC UK - to develop their eCall Marine system. eCall Marine reports automatically a "Man Overboard Alert" to a central emergency service centre with details on the incident. Start-up Ridersmate graduated from the centre 1 August 2018 after 18 months support.
