Appier Achieves 140% Average D7 ROAS for DRIMAGE’s New MMORPG ‘Architect’ Launch Campaign

• Maximizes high-value user acquisition and cost efficiency through AI-powered ‘AIBID’ solution
• Balances user scale and profitability through ‘Floating CPI’ and ‘Smart Inventory Selection’ in a highly competitive market

SEOUL, January 15, 2026 — Appier today announced that it achieved an average Day-7 Return on Ad Spend (D7 ROAS) of approximately 140% for the Korean launch campaign of ‘Architect: Land of Exile’ (hereafter ‘Architect’), a blockbuster MMORPG published by DRIMAGE and developed by Aquatree. The campaign successfully scaled user acquisition while maintaining stable performance efficiency during the critical launch period.

‘Architect’ is an MMORPG featuring lifelike characters and a vast, seamless single-channel world, launched in October 2025. Given the highly competitive Korean gaming market, where multiple major titles often launch simultaneously, standing out in a saturated market poses a significant challenge. During launch phases, intense bidding competition and limited user attention make it difficult to scale user volume while maintaining stable KPIs such as ROAS and retention. 

To navigate this environment, DRIMAGE set out to secure both performance efficiency and cost stability from day one. To support this goal, Appier utilized its AI-driven solution, ‘AIBID,’ to identify high-value users and optimize acquisition costs throughout the launch phase.

Unlocking Growth with Floating CPI and Purchase Lookalike Modeling

To maximize budget efficiency, Appier implemented its ‘Floating CPI with Upper-Bound Guarantee’ strategy. This approach dynamically adjusts bids based on users’ likelihood to convert, while setting a CPI cap to prevent sudden price spikes caused by post-launch competition, ensuring stable and predictable acquisition costs. 

In parallel, Appier utilized ‘Purchase Lookalike Modeling’ to precisely target users with high conversion potential. By expanding reach to audiences with behavioral profiles similar to existing purchasers, the campaign significantly improved acquisition efficiency without sacrificing performance quality.

Accelerating User Growth with Smart Inventory and Influencer Video Creatives

Appier further optimized media spend through Smart Inventory Selection, automatically prioritizing high-performing placements such as Kakao Bizboard to drive brand visibility. On the creative side, the campaign leveraged influencer-led gameplay walkthrough videos that intuitively showcased the game’s core mechanics and in-game experience. By naturally presenting real gameplay flow and key content, these videos improved user understanding and positively influenced install conversions. Combined with Appier’s AI-driven targeting, the creative strategies became a key driver for the overall campaign ROAS.

As a result, DRIMAGE achieved an average D7 ROAS of approximately 140% during the launch campaign, establishing stable and scalable user acquisition channels despite the high volatility typical of new game launches.

“In a crowded MMORPG launch environment, Appier enabled us to stand out by effectively scaling user acquisition while maintaining performance efficiency,” said Woochang Lee, Performance Marketing Team Leader of Drimage. “Despite intense competition and aggressive bidding, the campaign delivered nearly 140% average D7 ROAS during the launch phase, exceeding our expectations and providing strong confidence for our continued growth.”

“In a highly competitive market, precise user identification and adaptive cost management powered by AI cannot be overstated,” said Bo-hyuk Lee, Head of Ad Cloud Sales at Appier Korea. “We are pleased that Appier’s AI technology, combined with DRIMAGE’s sophisticated campaign strategy, led to tangible ROAS results. We look forward to continuing our support for our partners' business growth through data-driven optimization.”
