River Sentry was established in response to the devastating Central Texas floods in July 2025. The lack of an effective flash flood warning system at that time inspired founder Ian Cunningham, an airline pilot and ex-naval aviator, to assemble a dedicated team with a clear mission: to develop innovative flood solutions that prevent future flooding fatalities and create storm-resilient systems.
The team, based in Liberty Hill, Texas, developed an innovative flood solution in the form of a new type of flood alarm system based on three principles: effect, simplicity, and resiliency. This storm-resilient system aims to provide timely flash flood warnings to help communities better prepare for severe weather.
Just 3 months after the founding of the company, the first River Sentry RS-1A was installed, marking the beginning of our innovative flood solutions. Within 6 months, over 100 RS-1A's were operational along the Guadalupe River, providing essential flash flood warning capabilities and protecting campers, vacationers, and residents of Kerr County with our storm-resilient systems.

Ian is an innovator and creator with a passion for solving problems through innovative flood solutions and storm-resilient systems. His career as an airline captain and naval officer has instilled in him a strong belief that flash floods are a deadly threat that can be mitigated with the right technology. He now dedicates his life to realizing that belief.

Eoin built his career from the factory floor of Dell to being one of its Vice Presidents, driven by his huge passion for leaving the world a better place. With the increasing risks of flash flood warnings, he is committed to implementing innovative flood solutions and developing storm-resilient systems. He brings drive and organization to the team, enabling us to deliver on our promises.
