About メルカリ

日本初のユニコーン企業、メルカリは日本で最も多くのユーザー数を誇る、フリーマーケットアプリを運営しています。国籍に関わらず国内外から優秀な人材を大規模に採用しています。シリコンバレーにもオフィスがあり、アメリカ向けにローカライズしたメルカリアプリを開発し、アメリカのフリーマーケット市場でもシェアを拡大しているグローバルテック企業です。

「限りある資源を循環させ、より豊かな社会をつくりたい」。創業者である山田進太郎氏が世界一周の旅で抱いた、そんな問題意識によって生まれたのがフリマアプリ「メルカリ」です。テクノロジーの力によって、世界中の個人と個人をつなぎ、誰もが簡単にモノの売り買いを楽しめる。それにより資源を循環させる豊かな社会、個人がやりたいことを実現できる社会をつくっていきたいと考えています。

これまで中古品の売買は、実店舗で行うのが一般的でした。しかし、お店に行くのに時間がかかること、お店の品揃えが限られていること、販売店が介在することで買い手も売り手も価格が不明瞭になるなどの問題がありました。また、中古品を売買するためのオンライン・オークション・サイトでは、出品手続きが難しかったり、入札に時間がかかったりするなどの問題がありました。

メルカリでは、誰もがスマートフォンを使って簡単に商品を売買することができます。また、配送業者やコンビニエンスストアとの提携により、簡単で安価な配送方法を実現しています。買う側も売る側も個人を対象としたサービスなので、不要なものを簡単に売ってお金にする楽しさや、ユニークな中古品を見つけて買うワクワク感を誰でも味わうことができます。

Japanese Language Policy

Paid Leave
- Two days off per week (Saturday and Sunday), Japanese national holidays, New Year's vacation
- Paid Leave (starting with 10 days, adding 1 day each year)

Diversity
There is more diversity in the world than any of us can imagine. Diversity & Inclusion (D&I) is strongly linked to Mercari’s mission as we aim to build a company environment where everyone can be themselves and work to their fullest potential.

Diverse Backgrounds

We already have members with many diverse backgrounds at Mercari. Our goal is for everyone to have equal chances to do their best work, without dividing individuals into groups based on age, gender, sexual orientation, race, religion, physical ability, or any other identifying feature, and without classifying anyone as “majority” or “minority.” We strive to create various policies and initiatives to make this a reality.

No Quotas

Mercari does not set quotas, such as a 50:50 gender balance or a specific number of countries represented, because we feel labeling groups and people in terms of numbers goes against our ideal of respecting the diversity inherent to all individuals. Meaningful efforts towards diversity are reflected not in the quantitative goals many companies tend to rely on, but in the thoughts and behavior of every person within.

Our Focus

Providing fair chances for members of all backgrounds Fostering a culture of learning to allow everyone to reach their full potential Creating an organization built on trust so that everyone working here feels like they truly belong Our first step is for D&I to take root in the thoughts and actions of all members at Mercari.
