Engineering Team Leader: Take Your Leadership to the Next Level with AI x SFA/CRM for Enterprise

About Geniee Inc.

We were founded in April 2010 with the goal of creating a global tech company from Japan, like GAFA. We went public only seven years after our founding and have kept increasing both revenue and profit since then. We are a fast-growing company.

As a marketing technology company, we operate an ad platform business, a marketing SaaS business, and a digital PR business. We are a rare company that has both ad technology and marketing technology products, and we continue to grow.

In 2020, we were selected in the Financial Times “High-Growth Companies Asia-Pacific” ranking. In 2023, we established JAPAN AI Inc. as a wholly owned subsidiary to focus on the cutting-edge AI business. JAPAN AI’s technology creates synergy with Geniee’s existing products, and the group is achieving high growth. By offering state-of-the-art solutions, we help customers improve efficiency and productivity.

Note: The “High-Growth Companies Asia-Pacific 2020” ranking surveyed more than 50 million companies in 12 countries in the Asia-Pacific region. It selected 500 companies based on revenue growth from 2015 to 2018. Geniee ranked 357th overall and 11th among technology companies from Japan.
