FloodFlash rapid-payout flood insurance is changing the way commercial property owners manage their flood risk. Customers receive a pre-agreed settlement as soon as the FloodFlash sensor detects that waters have exceeded a critical depth. An algorithm is used to set tailored prices meaning that for the first time, personalised and competitive flood policies can be written for the highest-risk locations around the world.  Founded in 2017, FloodFlash has raised £2.1m seed investment and is headquartered in London.
