about us

We've been making great software in Sydney since 2006. In that time we've amassed over 500,000 mobile app downloads and 2,000,000 web app users.

Sentia is a family of keen web and mobile developers who love to create useful, usable, beautiful and sustainable software with the best available technologies and techniques.

We specialise in Ruby on Rails, iOS & Android development, but we'll use other technologies when it makes sense for the project - it's all about using the right tool for the job.

our proven process

We work for you by working with you. Amazing things come from collaboration.

Open and Honest Communication

We don’t just take your idea, run with it and leave you in the dark—you’re part of the team, and you’re involved at every stage. We rely on continuous feedback and close collaboration with you to build the best products possible.

Iterative Process

We believe that the most effective communication tool is working software. That's why our apps are tested continuously and deployed several times a week. Using your products and getting feedback let's you see what needs to be done to it.


We track everything we do—even non-billable work. This helps keep us on time and in-budget, and gives you an in-depth look at what we do behind the scenes. You’ll always know what we’re working on and who’s doing it.
