MUSINSA's Product Ads lets partners pay a fee, on top of their standard sales commission, to feature products in paid placements across the MUSINSA Store. The fee is also a revenue source for MUSINSA itself.
Many partners hand this work to agencies, who manage ad accounts and payments on their behalf. Ads Center 1.0 first turned Product Ads into an actual tool, but its limited functionality, including no direct way for agencies to log in, kept them from scaling ad operations. That gap pushed the team toward a full redesign.

Ads Platform 1.0 was built on top of MUSINSA's partner portal, which limited its scalability.
Because the underlying system couldn't be accessed externally, advertising agencies and partners from other platforms (29CM, SOLDOUT, and others) had no way to use the Ads Center.
As the number of advertisers grew, so did the demand for agencies to manage campaigns on their behalf, but this structural limitation meant the platform couldn't meet that demand.

Limited payment methods: the existing system supported only virtual account transfers.
Once a funded budget was depleted, recharging BizMoney through a virtual account (a manual process) introduced significant lead time, averaging 5.6 days as of April 2025.
