Case Study: Mercari achieves a 70% increase in U.S. Gross Merchandise Volume with Braze

How Mercari Uses Braze to Aid in Global Expansion

Mercari, the selling app, needed to grow its presence in the competitive U.S. market and simplify the traditionally clunky seller experience. To drive adoption and create more relevant, personalized user journeys, Mercari partnered with Braze and adopted the Braze customer engagement platform for targeted messaging and improved customer understanding.

Using the Braze platform, Mercari implemented personalized, targeted campaigns and A/B testing to boost conversion and lifetime value, then expanded the platform’s use to Japan. With Braze, Mercari reached 2 million U.S. monthly active users, achieved a 70% year‑over‑year increase in U.S. gross merchandise volume, amassed 45 million downloads, and now sees more than 150,000 new listings daily.
