We built zipBoard to make collaboration in the digital world easier. While spreadsheets are great, we believe visual details require an easier way to be discussed. Just the way you would do it on a real world , take a pen and markup to explain what you want changed. We believe it should be the same in the digital world, whether you are building a website, a course, a document, a video. That’s why we have created an easier way to markup and annotate on any kind of digital asset, making it easy for creators to collaborate - just like they would in the real world. We want to make it easy for creators to collaborate every day, without having to dial in a meeting, or make long lists on spreadsheets.

Sanctuary Computer is not a traditional studio.  We work asynchronously with lots of focus time and without Slack. We use tools optimized for calm, thoughtful communication, and opt for async whenever possible. We fight hard to maintain our focus time.    We think of our garden3d as collective for creative people, prioritizing a happy, talented, and diverse studio culture. We work on projects that bring value to our world, and we balance deep care for the work we do with a genuine curiosity about life outside of our jobs.    At the end of the week, we turn our computers off at 40 hours (or 32 hours via our optional 4-day workweek). At the end of the month, we take Friday off, and some go surfing.
