ECX Group

What ECX Group does

ECX Group Corporation (株式会社ECXグループ) is a Japanese holding company established in November 2023 through the stock-transfer integration of Japan EC Service Co., Ltd. (founded 2011) and Greenwich Co., Ltd. (founded 2003). The group operates two wholly-owned subsidiaries that together support Japanese SME e-commerce operators: Japan EC Service runs EC Masters Club, a membership-based unlimited-consultation service priced at ¥15,000/month with 2,500 paid members and 6,600 total member companies (~10% of Rakuten marketplace shops); Greenwich runs the Rakurakupon (らくらくーぽん) SaaS platform used by 3,000+ Rakuten marketplace shops and certified as a Rakuten RMS Gold Service, plus the LSEG LINE delivery service used by 1,500 of 7,000 Rakuten R-SNS contract shops.

The group employs a community-led, self-serve GTM combining seminars, live streaming, peer referrals, and Rakuten marketplace partnerships. Revenue is generated primarily through recurring monthly subscriptions across the EC Masters Club membership, Rakurakupon SaaS subscriptions, and LSEG messaging service fees. As of 2026, the company has appointed IPO-experienced advisors, a new COO, and relocated its headquarters from Minato to Shibuya, with all signals pointing toward governance professionalization in preparation for a potential public listing.

Underlying technology is a combination of community/forum platform, marketplace-integrated SaaS tooling (with Rakuten RMS API integration yielding Gold Service certification), and LINE messaging delivery infrastructure. Registered capital stands at ¥60 million. The group has no disclosed external venture capital or private equity backing and no disclosed AI/ML capabilities; competitive positioning relies on 13+ years of accumulated e-commerce domain knowledge, an established member community, and privileged distribution via the Rakuten partnership.
