PeptiDream is now a $7 billion company and is also a founding investor in a contract manufacturing company, PeptiStar. Collaboration with other companies is crucial, says PeptiStar CEO Kameyama Yutaka, as new ecosystems for research, manufacturing and supply of peptide drugs are developed. In fact, PeptiDream, together with other co-founding investors Shionogi and Sekisui Chemical, has attracted additional ten investors as active R&D collaborators.
