Is there any prestige classes that are compatible and complement kineticists?
There exist no prestige classes that allow you to continue Kineticist progression, so any prestige class you take is going to stunt your blasts, talents, infusions, and other effects.
The only real exception is Evangelist, which will let you give up only one Kineticist level for an array of random benefits.

I just looked at that class and other than the 1 level loss, those benefits can be pretty good. Same HD, fort save will take a hit but we don't care about that, same BAB, +2 skill points and you get to pick any two skills to become new class skills, and the boons. Depending on what deity you worship those boons could be pretty nice.
It's a shame that my deity, Calistria, seems better suited for a Bard or other CHA class to go that route.
