Overview

FloodMapp is a Brisbane-based climate technology company that delivers live, property-level flood intelligence to emergency managers, government agencies, insurers, utilities, and critical infrastructure operators. Founded in 2018 by flood engineer Juliette Murphy and software engineer Ryan Prosser, the company was born out of the devastating 2011 Brisbane floods and a shared mission to ensure no lives are lost in flood events.

The company's proprietary DASH (Dynamic Automated Scalable Hydroinformatics) platform combines big data analytics, automation, and machine learning with novel hydrology and hydraulic models to deliver large-scale, rapid flood modeling. FloodMapp's models correctly identify up to 85% of inundated properties when compared against state government damage assessment datasets.

FloodMapp has grown rapidly since securing $8.5 million AUD in seed funding led by Union Square Ventures' Climate Fund in early 2022, with annual revenue surging more than 1,370% that year. The company now has operational coverage across the continental United States and Queensland, Australia, spanning over 195,000 miles (314,000 km) of stream sensor networks, with new regions coming online regularly.
