Our story

Adam Hynes and John Kelleher, from Cork Ireland, met while studying software development at Munster Technological University and like a lot of people, they are very concerned about climate change. As new dads, the two Irish men knew they needed to help in the fight, if not for themselves, then for their two sons.

Adam and John are both software developers with more than 30 years of combined experience launching products across the world. They have successfully built solutions that connect people and give them access to tools that they need to help solve their problems. They knew they could use their skills to help others who may also be feeling helpless and not knowing where to start with climate change. This is why they launched

The Offsetter platform

The Offsetter platform provides a simple and intuitive way for individuals and businesses to calculate, offset and reduce their carbon footprint. “Carbon footprint” is the term for the greenhouse gases generated by the day to day activities of a person or business.

Each individual or business on the platform can keep track of their monthly carbon footprint. They can quickly see if and how their actions are helping to reduce their carbon footprint and offset it accordingly. The lower the carbon footprint, the lower the contribution to climate change.

Even though they may have signed up as an individual or a small company, they will see that they are part of a greater community of Offsetters making a real impactful difference.
