Mercari

Mercari is Japan's first tech unicorn and one of the world's largest C2C marketplace platforms, enabling anyone with a smartphone to easily buy and sell secondhand items. Founded in Tokyo in 2013, the company's mobile-first marketplace allows users to list items for sale in under a minute with the camera on their phone, and connects them with buyers across Japan and the United States. Mercari has grown into a group of businesses including Merpay (mobile payments), Mercoin (crypto), and Mercari Shops (business merchant platform). The platform runs on a microservices architecture deployed on Google Kubernetes Engine and Google Cloud Platform, with backend services predominantly written in Go. Mercari went public on the Tokyo Stock Exchange in 2018 and continues to expand globally with a dedicated US marketplace.
