The night of June 3–4, 2026 came as an unpleasant surprise for many media buyers. In-app DSP Moloco started mass-disabling agency accounts, and the restrictions affected not only iGaming but other verticals as well. Numerous ad campaigns were stopped, while some advertisers faced limited access to their accounts and funds on their balances. Moloco continues to develop its agency business, but at the same time is tightening app registration and access requirements, so media buyers have a reasonable question: “What can replace Moloco?”

Recent events have once again shown how risky it is to depend on a single traffic source. The shutdown was easiest for those who had diversified their sources one way or another, so if you still haven’t done it, we strongly recommend reading this article. Specialists from the advertising platform RentAcc prepared an overview of 3 platforms that many teams use as alternatives to Moloco.

How Did the Moloco Shutdown Affect the Market?

In-app advertising has plenty of advantages compared to advertising on social networks. It is better suited for verticals where game mechanics can be used in creatives. If an offer can be presented as a mini-game using a playable creative, achieving higher conversion rates is usually not difficult. This approach lowers the initial barrier for the user and helps increase engagement.

Moloco Ads was one of the key in-app sources for many teams. The platform boasted massive device and app coverage, allowing advertisers to run campaigns in iGaming, betting, fintech, crypto and other verticals as long as they complied with the platform’s requirements. Therefore, the mass shutdown of agency accounts seriously shook the market: some teams lost their main traffic source, while others started urgently reallocating budgets and looking for new sources to shift their volume to.

If you were working with white-hat approaches, you will most likely be able to keep launching campaigns. As for when Moloco will return to its previous model of working with grey verticals, no one can say yet, but this niche certainly won’t remain empty for long. Advertisers will gradually move to other in-app sources: Unity Ads, BIGO Ads and Kayzen. Let’s break down how they differ, what tasks they are suitable for, and what you should keep in mind when launching campaigns.

Unity Ads

The platform from Unity Technologies that serves ads in mobile games built on its engine. 70 of the 100 most successful iOS and Android apps in the US use Unity advertising solutions. The source is in many ways similar to Moloco, but with additional placement management capabilities through whitelists and blacklists.

Advantages:

  • Large audience reach. Unity has 256 million monthly active users, providing reach on par with leading social, streaming and entertainment platforms.
  • Optimization for ROAS and Retention Rate. Optimization toward retention goals allows you to reach audiences that are more likely to download your app and continue using it.
  • APK app launches are supported. Running Android apps without publishing them on Google Play? Unity accounts from RentAcc allow you to launch ad campaigns for APK files. For iGaming teams, this is a great way to scale campaigns more consistently and reduce dependence on app takedowns.

To get the most out of Unity Ads, it is important to take the specifics of the vertical into account and test different approaches to campaign launches. The RentAcc team has significantly streamlined the workflow and eliminated routine tasks by adding the ability to manage spend and top up accounts through automated rules. Launch campaigns through RentAcc agency accounts and get full control over your advertising account through a convenient CRM. With support from managers, getting started with a new source becomes much easier.

BIGO Ads

A mobile advertising platform with its own BIGO Audience Network. The source reaches a multi-million audience across the CIS, Asia, and the Middle East. Ads are served inside popular apps like Likee and Imo.im and are primarily aimed at a younger audience. You can launch In-App traffic through a network of 50,000+ partner apps.

Advantages:

  • Potentially affordable traffic costs. In certain GEOs and verticals, BIGO can deliver competitive CPI and is suitable for testing new campaigns.
  • A wider range of allowed verticals. As long as platform requirements are met, BIGO allows you to run a number of verticals that can be more difficult to work with on some major advertising platforms.
  • CPA optimization. The platform supports campaign optimization for specific in-app actions, such as registration or purchase.

When working with BIGO Ads, it is important to consider the specifics of its audience. Likee is essentially a TikTok alternative with a predominantly young user base, so offers and creatives should be selected accordingly.

Recently, launching campaigns in BIGO Ads through self-serve accounts has become more difficult, so many media buyers are switching to RentAcc agency accounts. An agency account has higher trust and allows you to top up the balance without having to look for cards for every working GEO. By the way, the minimum top-up is currently only $300.

Kayzen

A mobile DSP platform for user acquisition and re-engagement. It operates through programmatic auctions with CPM-based pricing. The source allows advertisers to reach more than 1.9 billion unique users across 180 countries.

Kayzen focuses on auction transparency, mobile inventory and the ability to independently configure your strategy around specific KPIs. Its proprietary kAI Core technology is responsible for bid optimization and budget allocation, using machine learning to improve campaign performance.

Advantages:

  • Proprietary bidding system. This allows you to manage bids independently, while other manual settings let you flexibly adapt your traffic-buying strategy to specific KPIs. The result is greater transparency, predictability, and control.
  • Wide scaling capabilities. Kayzen allows you to buy mobile traffic on a global scale and work with audiences across different GEOs without being tied to a single market.
  • Traffic quality control. The platform provides whitelists and blacklists for apps, placements, and audiences, allowing you to keep only effective sources and cut off underperforming placements.
  • Flexible targeting. You can set specific GEOs, devices, operating systems, carriers, and platforms as targeting parameters.

When working with Kayzen, it is important to analyze the stats, test different apps, and gradually scale winning campaigns rather than simply launching a campaign and waiting for automatic optimization. RentAcc agency accounts provide access to the platform with ready-to-use infrastructure and support from experienced managers. Few companies can offer this kind of setup, so you know who to turn to.

Conclusion

The situation with Moloco once again showed how risky it is to rely on a single advertising source. Even major platforms can change their terms of service within a short period of time, and dependence on one source can turn any ban or restriction into a serious problem. The teams that win are those that test alternative in-app sources in advance and distribute their budgets across multiple platforms. With this approach, you can adapt to changes faster and keep your workflow running.

When connecting through RentAcc, you get:

  • agency accounts for Unity, BIGO and Kayzen;
  • manager support with campaign launches and optimization;
  • account, balance and spend management in a single interface;
  • Telegram notifications about top-ups, balance changes, and account statuses;
  • the ability to add the same app to multiple Unity accounts without rejection due to duplicate apps.

It is better to prepare a backup source in advance than to look for one after your main channel has already gone down. Any of the advertising platforms described above can be used to test new campaigns, diversify your advertising budget or scale winning campaigns. Get a Unity, BIGO, or Kayzen agency account through the RentAcc Telegram bot, test sources in parallel and don’t wait for the next restriction to start diversifying your traffic.
