Our Story

Our journey so far

h2x team

In 2019, a Mechanical Engineer frustrated with spreadsheets and tedious processes joined forces with a software engineer who was looking to make a big impact on the construction industry.

h2x formed and in 2020, we launched a simple cold water pipe sizing tool.

The response from the industry was incredible.

Why? The tool was intuitive and had clearly been designed with the end user in mind.

Something that building services engineers were not used to.

Fast forward to today and the team is stronger than ever and the product is improving faster than ever.

We have users across four continents, from the world's largest companies, designing the world's most famous projects

Our vision

We're only just getting started

Our vision for the future is to continue breaking boundaries in the field of engineering.

We aim to further streamline and optimise processes, enabling engineers to focus more on innovation and less on tedious tasks.

By continuously improving with cutting-edge technologies, we aspire to be the gold standard in engineering software, substantially impacting projects of all sizes.

We envision a future where our tools are an integral part of every successful engineering project, no matter where it takes place.
