Passage: Initially, Thatgamecompany consisted of Chen, Santiago, Nick Clark, who had collaborated with Chen on Flow, and John Edwards. Santiago was the president of the company and the producer for its games, Clark was the designer, and Edwards was the lead engineer. Although Chen cofounded the company, he initially worked at Maxis on the game Spore. The company considered adapting Cloud as their first product for Sony, but instead decided on Flow, as it was "more fleshed-out as a design". They felt that it would be easier than Cloud to develop while they built the company; no members of the team had experience with managing a business or with creating a commercial game. Several contract workers assisted Thatgamecompany with Flow's development, including Austin Wintory, the game's composer.The company had believed that the PlayStation 3 version of Flow could be completed in four months, and that it would be ready for the November 2006 launch of the PlayStation Network.

The game was well received; it became the most downloaded game on the PlayStation Network in 2007, and was nominated for the Best Downloadable Game of the Year award at the 2008 Academy of Interactive Arts & Sciences Interactive Achievement Awards, and for the Best Innovation award at the 2007 British Academy of Film and Television Arts (BAFTA) awards. After its release, an expansion pack and a PlayStation Portable version of the game were created by SuperVillain Studios. Thatgamecompany was not involved in the development of either project beyond ensuring that they retained the same design and art direction as the original, as they were busy creating their next title, Flower.Flower was Thatgamecompany's "first game outside the safety net of academia", according to Santiago.
