A graduate of Parsons School of Design, Coco Masuda has been an illustrator, artist, graphic designer, artist's agent, and consultant based in Tribeca, New York City. With the motherhood and the family circumstances, she had a wild ride in her career in the last ten years or so. 

Besides continuing her creative career, she worked for a Gallery in Chelsea for a year and a half and was instrumental in starting a program to introduce Japanese and other foreign artists to the New York and art market. After leaving the gallery, she continued to represent a few Japanese fine artists. From the summer of 2013, she became a successor of a shipping and remittance company in Tokyo and worked on the rebranding of the company, then 2 and half years later, successfully sold it to a direct competitor. These experiences prepared her to start CoCollaborations in July 2017.
