Rakuten Symphony, Inc.

Rakuten Symphony, Inc. builds technology rather than buying it. Founded in Tokyo in 1997 as an online marketplace, the company now operates over 70 businesses across e-commerce, fintech, digital content, communications and professional sports, spanning 30 countries with nearly 32,000 employees and about 1.7 billion members and users worldwide. Its technical work is distinctive in that the mobile network, the payment platform and the artificial intelligence systems underpinning these businesses were constructed in-house instead of purchased off the shelf.

That engineering posture shapes the working environment. Technical domains in play include e-commerce platforms, fintech and payment platforms, mobile networks and telecommunications, artificial intelligence systems, and digital content and communications platforms. The businesses are unified by a membership ecosystem that pays Cash Back to members across services - over $4.6 billion since 1999 - which places a premium on systems that interoperate and compound value across the portfolio rather than standing alone.

The company's name means 'optimism' in Japanese, and that philosophy, alongside a stated mission of contributing to society through innovation and entrepreneurship, informs an entrepreneurial culture built on ecosystem thinking: services designed to work together for users and partners. Headquarters are in Tokyo, with operations across 30 countries.
