Overview

Rainsurfer Limited, registered with CRO 623824, is a Dublin-based company founded in 2018 by Peter Ryan, a Scotsman who has lived in Ireland for over 20 years. The company was established after Ryan, inspired by his son's school project on water conservation, began exploring ways to repurpose rainwater for practical uses such as flushing toilets and handwashing. He identified a gap in the market where rainwater collected in barrels was underutilized despite being available. After testing various solutions, Ryan developed a prototype using a spiral pump, which he believed could efficiently channel rainwater into domestic uses. The company's focus appears to be on innovative, sustainable water reuse technology, with development supported by Enterprise Ireland and TU Dublin. The name suggests a focus on environmental technology and water conservation. Beyond registry-level identification, no further business details are publicly captured.
