The FlowStop story began after witnessing the devastating effects of frequent flooding in vulnerable communities. Traditional flood prevention methods were often costly, complex and inadequate to effectively protect homes and businesses from unpredictable weather.
Driven by a passion for practical solutions, our founder Olivier Guillou set out in 2019 to develop a flexible, accessible and highly effective flood barrier. In 2021, FlowStop was born: a bespoke inflatable flood barrier designed to provide reliable defense against rising water. The goal was simple: to create a product that was easy to install, reusable and adaptable to any opening, giving homeowners control over their flood protection. Bertrand Sylvestre-Boncheval joins FlowStop in 2022, bringing his entrepreneurial expertise to drive innovation and growth in flood protection solutions.
