About PlaceChangers

Our mission

PlaceChangers stands for award winning town planning software! Our cutting-edge tools help planners replace outdated and time-consuming processes with modular, user-friendly solutions to create better projects and bring the power of digital planning to your fingertips.


Our story


In the tumultuous times of the Covid-19 pandemic, our co-founders were inspired by the critical need for healthier and more resilient communities. They envisioned a world where planners have easy access to all data and insights needed to shape high quality projects.

With a combined wealth of experience in planning and digital technologies, they understood the critical need for simplifying complex processes and making them accessible to a broader audience. 

This is how PlaceChangers was born, a platform for planning professionals centred on interactive proposal mapping and offering intuitive, yet powerful analytics and consultations that are easy to use.
