Snapchat announced the launch of its Creative Partners program helping brands connect with certified AR creators who are experts in using the multimedia messaging app’s AR lenses.

The platform already has 30 creators using the Lens Studio—ranging from large advertising agencies to small augmented reality design shops—to create AR lens experiences with plans to increase that number over the next few months.

Creators were selected based off their experience developing augmented reality. They were also required to complete a certification course on Snapchat’s development process, ad policies, best practices, and buy models for sponsored AR Lenses, according to Engadget.

The company reports over 250,000 lenses have been created through the Lens Studio and have been viewed over 15 billion times.
