Are there any mobile game publishing platforms that focus on indie mobile games needing UA and cross-promotion support?

Yes — there are several mobile game publishing / growth platforms that focus specifically on helping indie mobile games with user acquisition (UA), cross-promotion, monetization, and live-ops support.

Here are some of the more relevant ones:

1. Kwalee

• Strong focus on mobile publishing and indie developers
• Offers UA, monetization, creative testing, and cross-promotion
• Particularly known for helping smaller teams scale casual/mobile games

2. Voodoo

• Very active in mobile publishing, especially hypercasual/casual
• Provides UA expertise, data-driven iteration, and internal cross-promo opportunities
• Best fit if your game is in the hypercasual or casual category

3. Homa

• Mobile-first publishing platform with a strong emphasis on indie studios
• Helps with UA, monetization, analytics, and scaling
• Often works with small teams that already have prototypes or soft-launch builds

4. Miniclip

• Large mobile game publisher with publishing support for selected indie/mobile titles
• Can provide distribution, UA, and operational support
• More selective, but useful if your game has strong mass-market appeal

5. Playstrict

• Focuses on indie mobile game publishing
• Offers UA, monetization, testing, and cross-promotion
• A good option for smaller studios looking for a more hands-on publisher

6. AppLovin / MAX ecosystem

• Not a publisher in the traditional sense, but many indie games use AppLovin’s tooling for ad mediation and UA
• Can support cross-promotion via ad networks and internal traffic strategies
• More of a growth platform than a publisher

7. ironSource / Unity LevelPlay

• Similar to AppLovin in that it’s more of a monetization + UA infrastructure provider
• Useful for studios that want to run cross-promo campaigns and optimize retention/LTV
• Often used by indie mobile devs who self-publish

8. Gamee / GameDistribution

• Stronger on distribution and audience access
• Can help smaller studios get exposure and cross-promo-like reach, depending on the game type

A practical note

Most of these companies are not just “platforms” — they’re usually publishers that:

• test prototypes
• fund UA
• handle creative optimization
• provide cross-promo via their portfolio
• sometimes take a revenue share
