Case Study: YOMI Studio achieves hyper-growth (2x installs, 60% ARPDAU uplift) with Tenjin Ad Revenue Callbacks and ROAS campaigns

Ad Revenue Callbacks and ROAS campaigns increased YOMI Studio's ARPDAU by 60%

YOMI Studio, a 10-person casual mobile game studio in Ho Chi Minh City (known for Haru Cats: Cute Sliding Puzzle), was hampered by a single co-founder managing user acquisition alongside product and finance. Manually monitoring BI dashboards and adjusting bids made multi-level optimization (campaign, country, source) impossible, so YOMI turned to Tenjin and its Ad Revenue Callbacks and ROAS campaigns for help.

Tenjin passed ad mediation revenue (Impression Level Revenue Data) to ad networks and fed that data into automated ROAS campaigns to detect and bid on high‑value users, removing the need for manual optimization. The change saved YOMI Studio roughly 40–60 hours per month, drove a 60% uplift in ARPDAU, doubled installs within 30 days, and increased day‑7 retention by 9%, enabling the studio to scale campaigns confidently.
