fluct Inc. Enters Strategic Partnership with ADPOPCORN to Launch "Reward Ads Plus" — Japan’s First Official Agency to Offer Direct PayPay Point Incentives for Video Ads

TOKYO, April 1, 2026 — fluct Inc. (Headquarters: Minato-ku, Tokyo; CEO: Yota Fujii; COO: Takeshi Kuroda), a group company of CARTA HOLDINGS, Inc., is pleased to announce a strategic business partnership with ADPOPCORN Co., Ltd. (CEO: Heungtaek Kim), a leading mobile advertising monetization platform and subsidiary of the South Korean data-tech giant IGAWorks, Inc.
Through this partnership, fluct has secured the rights as the first official agency in Japan to offer "Reward Ads Plus," a solution that allows apps to instantly grant PayPay Points to users as a reward for watching video advertisements. Full-scale service and implementation support begin today.
This collaboration enables app developers to provide incentives via PayPay, Japan’s leading payment service with 72 million registered users (as of December 2025), in addition to traditional in-app items. As the first official domestic partner, fluct will provide one-stop support—from integration design to operational consulting—to maximize ad revenue and drive business growth.

Background: The Launch of "Reward Ads Plus"

ADPOPCORN is a global mobile monetization platform reaching over 24.6 million daily users. In South Korea, its model utilizing "NAVER Pay Points" has delivered dramatic results, including a 2x increase in ad participation rates and a 40%+ improvement in user retention. Recognizing this success, fluct is bringing this high-performance model to the Japanese market.

Key Features and Benefits of "Reward Ads Plus"

1. Strong User Hook via "PayPay Points" Users receive highly popular PayPay Points instantly upon completing a video ad. Using a high-utility currency as an incentive encourages participation across a broad user base, including casual users.
2. "Two-Tier Structure" to Maximize Revenue In addition to standard rewarded video ads, the system displays a short-form ad (5 seconds or less) when a user opens the "Point Capsule Gacha" to claim their reward.
   • Tier 1: In-app rewards granted for watching a video.
   • Tier 2: Additional revenue from short-form ads displayed during the Gacha sequence. By inserting ads at the moment of high anticipation (opening the Gacha), apps can maximize ARPU (Average Revenue Per User) while maintaining high completion rates.
3. Entertainment Experience Tailored for Japan The solution utilizes a "Gacha" (capsule toy) mechanic, a format deeply familiar to Japanese users, providing a gamified and engaging user experience (UX).

Strengths of fluct’s Consulting Support

As the official agency, fluct’s specialized team—experienced in monetizing diverse categories including "Poi-katsu" (reward-earning), Manga, and Gaming apps—will provide:

• Optimal Reward Design: Balancing point distribution to maintain the app’s internal ecosystem.
• Implementation Support: Technical follow-up for integrating overseas SDKs and tools.
• Revenue Optimization: Continuous consulting on Gacha probability adjustments and maximizing fill rates in collaboration with ADPOPCORN.

Future Outlook

Through "Reward Ads Plus," fluct aims to solve monetization challenges for app publishers while enhancing user experience and fostering robust business growth.

"ADPOPCORN is a mobile advertising monetization platform providing ads and rewards to over 24.6 million users daily. Our model using 'NAVER Pay Points' in Korea has seen dramatic success, doubling participation and boosting retention by over 40%. For our full-scale entry into Japan, partnering with fluct—a leader in domestic ad monetization—ensures that Japanese publishers can implement this solution smoothly and strategically."

Yota Fujii, CEO of fluct Inc.

"We are thrilled to be the first to bring ADPOPCORN’s high-performing solution to Japan. Japan is one of the world’s leading markets for 'Poi-katsu' (reward-earning) culture. We are confident that combining 'PayPay,' now a vital part of daily infrastructure, with gamified rewarded ads is a monetization method perfectly suited to Japanese user psychology. Through this partnership, fluct will go beyond providing ad space to build new revenue models that deepen engagement between users and media."
