All Good Things…

Original Structure Sensor has been replaced by Structure Sensor Pro.

When Occipital launched the original Structure Sensor (ST01) in September 2013, we didn't know if it would be a success or not. We were building sophisticated hardware for the first time, and we put the whole team on it. This was a "bet the company" move, and we were excited to see it pay off in a successful Kickstarter campaign where we raised almost $1.3 million.

Since that launch, the original Structure Sensor has attracted a developer community that numbers in the thousands and which has created over 130 publicly-available apps. In turn, the Structure platform has radically changed how work gets done in industries ranging from architecture to medicine to visual effects.

As we say goodbye to original Structure Sensor, the platform it created is moving into the next generation. Structure Sensor Pro, Occipital's totally redesigned depth sensor for iOS, is available for purchase and integration into a whole new world of apps and experiences. We'll be updating our Featured Apps page as all of your favorites are upgraded to work with Structure Sensor Pro.

To everyone in the Structure Sensor community, all of you developers, customers, and creators: thank you. We still can't wait to see what you do with it.
