Spend Time on the Things That Matter

Opendoor relies on CircleCI for fast, bug-free software builds

Why CircleCI?

Opendoor helps take the hassle out of home buying and selling, so people can sell their houses quickly and get great deals on new homes. The company has been using CircleCI since Opendoor launched in 2014, and can roll out new product features faster while improving developer productivity. “As we grow, it’s important that software quality doesn’t deteriorate,” says Zain Memon, Opendoor engineer. “CircleCI helps us make sure that quality remains high.”

The Challenge

Opendoor splits its development team between product engineering and data science, since it builds tools for home buyers and sellers and also crunches data to predict home values and market risk. Since developers are always iterating new features, like an app for scheduling home viewings, they need to test dozens of new builds a day.

The Solution

With CircleCI, Opendoor developers can quickly run tests on every commit. By finding and fixing bugs before going into production, developers can be sure they’re delivering quality software. Since they spend less time on iterating while also boosting quality of software, Opendoor developers can focus on brainstorming new product features that customers need. “CircleCI helped us shave many minutes off our build time. We save tons of developer time with CircleCI,” says Zain.
