Kellee Santiago is President and Co-Founder of the video game development studio, thatgamecompany. thatgamecompany's goal is to make video games that communicate different emotional experiences the current video game market is not offering. The studio encourages innovation and experimentation and believe that fresh, creative games will appeal to new, yet untapped, audiences.

thatgamecompany was founded in the Spring of 2006 by Jenova Chen and Kellee Santiago, two graduates of the University Southern California Interactive Media MFA program. They had worked on several projects together, including the multi-award winning student game, "Cloud," and decided to continue working together on small, experimental games by forming a game studio that would focus on these projects. thatgamecompany is currently in development on their second downloadable game for the Playstation 3, "Flower."
