Mobile publishers who place your game with 3rd party stores (not Apple/Google)?

Hey reddit,

Was just wondering if there are publishers who will take your (mobile) game to the third-party app stores. There are plenty of publishers who do the mainstream stores like Apple/Google/Amazon, but I have not heard of the 3rd party publishers.

Would be really thankful for the hints!

P.S. google search pops a lot of 3rd party stores, but not the publishers, or it is just my "godlike searching skill"
