He also assembled a team to help him put together the platform. He even added Jared and Gilfoyle to the team. As for Erlich, he traded his equity for a Corvettte that Jian-Yang bought using the rest of the funding money for the Seefood app. Periscope also acquired the app for $4 million (AU$5.37 million) after Jian-Yang tweaked it as a unique filter for men's private parts.
