Job Description

Having a new house is great. Getting a new house isn’t. It's a big life moment and can be complicated and scary for all of us.

That's why we’re on a mission to remove risk so people can move fearlessly. We use tech, design and data to make dealing with clients secure and friction-free for lawyers and professional services across the property sector.

We already work with over 700 property and legal businesses to help streamline their processes and keep security top of mind, and we're growing. We're serious and we're ambitious. Come join us.
