Castbox was founded in 2016 by company CEO Renee Wang in Beijing, China.[1][2] It also has offices in San Francisco and Hong Kong.[3]


Castbox is an app that distributes free podcasts.

In addition to its library of podcasts from other distributors, Castbox also produces its own shows. In 2018, Castbox partnered with Heard Well on the podcast series Heard Well Now, which highlights early career musical artists.[7] As of 2018, Castbox produced 25 different original podcasts,[8][9] with This Sounds Serious, being released in 2019.[10]
