Join Our Team!

This year in 2022 we are growing the team to build new interactive, data-rich features and strengthen the product architecture to support our growing client base, and build on our customer success framework.


We are a team of 10 who are passionate about communities and our customers. We are primarily a remote company, but we love to get together and connect in real life. We meet up once a month in London to brainstorm new ideas, collaborate and grab a drink.  If you’re excited by the potential of working on some of the most important projects in democratic planning today to create a more positive and sustainable future, we’d love to hear from you.
