As the hunt for the elusive dark matter progresses, an impressive series of null results has severely limited options for DM that freezes out via standard model interactions. A hidden sector containing the dark matter particle and an unstable mediator can freezeout independently of the sector's very weak connection to the standard model fields, opening opportunities for phenomenology. I will present two minimal simplified models for hidden sector freezeout (through the vector and scalar portal), discuss the existing constraints on these parameter spaces from a wide array of complementary experimental approaches, and address how the features of these models survive in extensions beyond the minimal case.
