Mercari was launched in 2013 and has since become the largest mobile marketplace in Japan with over 54 million downloads worldwide.
We are on a mission to become a truly global marketplace. With a fast-growing user base in the US of over 19 million downloads and a new office in the UK, we are on our way to doing just that.
Investors love us too! In March of this year, we raised $75 million in a round of funding, becoming Japan’s first pre-IPO unicorn.
We are serious about creating innovative services that will leave mark on the world and change the way people shop.

Mission statement:
Create value in a global marketplace where anyone can buy & sell

Our world today is overflowing with things and services. New things become old quickly, and we are constantly creating waste by throwing out things that could still be used by someone else. Starting in Japan and the US, Mercari wants to eliminate waste worldwide by enabling peer to peer selling with our safe and easy-to-use flea market app.
