Dan Horrigan started the FuelPHP framework in late 2010, and was later joined by Phil Sturgeon, Jelmer Schreuder, Harro Verton, Frank de Jonge, Steve West and Márk Sági-Kazár. The first stable version was released on July 31st, 2011 and this book is based on FuelPHP 1.7.2, the latest stable version available as of writing this book. With over 300 contributors, its community is large and active.
The core team is currently working on the second version of FuelPHP; several alpha versions of it have already been released.
If you want to know more about the FuelPHP team and the framework philosophy, I recommend you to read the About FuelPHP section of the official website at:

If you have any questions about FuelPHP or encounter any issues, you can search the official forum (http://fuelphp.com/forums/) and start a new discussion if you don't find any answer. In a general manner, the official website (http://fuelphp.com) is an excellent resource.
