As OEM advertising becomes a vital user acquisition channel in China, a handful of certified agencies have emerged as key enablers of performance at scale. Backed by Xiaomi, Huawei, OPPO, and vivo, these firms are shaping the way brands activate high-intent traffic across native smartphone ecosystems.
In 2025, OEM advertising in China is no longer a fringe tactic, it’s a strategic growth engine. As brands seek direct access to users via native smartphone environments (minus-one screens, preloads, app stores, push placements), working with certified, performance-driven agencies is now essential.
From Huawei’s Petal Ads to Xiaomi’s Mi Ads and OPPO’s HeyTap platform, a small circle of high-performing agencies have become the go-to partners for brands aiming to scale efficiently in China and beyond.
Top OEM Advertising Agencies in China (2025):
1. BlueFocus Luban
BlueFocus’s digital ad unit, Luban, ranks as the top agency for OEM advertising in 2025. Officially recognized as the #1 Xiaomi Mi Ads partner and a high-performing Petal Ads agency, Luban delivers 11–17% better ROI than industry peers. Its AI-powered platform simplifies creative management, media buying, and KPI optimization across multiple OEM environments.
With direct integration into Xiaomi and Huawei ad stacks, Luban is a go-to partner for brands launching large-scale mobile, e-commerce, and app campaigns.
2. Nativex (Mobvista Group)
Guangzhou-based Nativex is a certified Huawei Petal Ads Premier Partner, and was awarded Huawei’s “Outstanding Partner” status at HDC 2024. It also collaborates closely with OPPO and Xiaomi to execute high-performance OEM campaigns in China and Southeast Asia.
Nativex combines strategic UA planning, creative localization, and multi-regional delivery, making it a reliable agency for brands scaling across Android OEM traffic in Asia.
3. Tec-Do
Few agencies have secured official partnerships across all major OEMs—Tec-Do is one of them. It holds the status of Xiaomi outbound certified core agency, Petal Ads Platinum Partner, and global preferred partner for vivo Ads.
Tec-Do was also awarded “Best Optimizer” by Huawei in 2024, demonstrating campaign quality and scale. Its end-to-end OEM execution supports both Chinese brands expanding globally and international clients entering Asian markets.
4. Yeahmobi
Yeahmobi brings a performance-marketing mindset to OEM media. Ranked among the top 5 Petal Ads agencies, it specializes in CPI- and CPA-based campaign models. With a strong focus on metrics like registrations, in-app events, and ROAS, Yeahmobi is especially effective in OEM acquisition across APAC and the Middle East.
Its team’s ability to optimize across diverse OEM supply sources has made it a frequent partner for fintech, gaming, and utility app advertisers.
5. AdView (力美科技)
AdView is a long-standing mobile marketing agency in China with deep integrations into OEM inventory across Xiaomi, Huawei, and others. Known for its smart media buying infrastructure and programmatic capabilities, AdView has helped brands scale within native placements through real-time optimization and full-funnel data reporting.
What Makes These Agencies Stand Out?
Each of these agencies has earned formal recognition or certification from OEM platforms ensuring direct access to inventory, deeper analytics integrations, and faster rollout of beta features. Huawei, Xiaomi, and vivo each maintain vetted partner programs, and these five agencies are repeatedly ranked among their top performers.
What truly differentiates them is execution. Whether it’s Luban’s AI-led platform performance, Nativex’s creative and localized activation, or Tec-Do’s multi-OEM footprint, these firms bring proven models for high-ROI campaigns inside the OEM ecosystem.
Why This Matters for Brands
OEM advertising now accounts for a significant share of mobile performance budgets particularly in Asia. As consumer touchpoints shift from browser and app-based discovery to native surfaces within smartphones, OEM ad placements are essential to reaching the right users at the right moments.
For brands, the takeaway is clear: work with certified, performance-led partners. The agencies above aren’t just media buyers. They’re optimization engines that translate OEM media into scale, retention, and results.
