What Le Grand does

Le Grand Co., Ltd. (株式会社ルグラン) is a Tokyo-based boutique creative performance agency founded in 2006 by former Overture Services (now Yahoo!) management personnel Izumi Hiroto and Yamabe Hitomi. The firm combines bespoke digital marketing consulting with a portfolio of proprietary AI/marketing-technology products, serving Japanese and international enterprise clients plus tourism organizations. Its consulting work spans DUX (data-driven UX design), CRM strategy (Salesforce, Dynamics CRM), search marketing, content marketing, social media, tourism marketing, and big data analytics, with a customer roster that includes Volvo Car Japan, Zurich Insurance, Zendesk, Unity, Peach Aviation, SCSK, Renown, Isetan, and Mitsui Shopping Park LaLaport.

The company's productized technology stack centers on three core assets: SmartUX, a patented WordPress-plugin marketing automation tool with self-serve tiered subscriptions ranging from ¥19,800 to ¥248,000/month; TNQL, a weather-driven AI recommendation engine offered as a freemium API covering ~300 predefined Japanese locations plus paid GPS-based global coverage; and weathermarketing.net®, a patented weather-triggered advertising delivery platform integrated with LINE Ads, GeoLogic Ad, and Adinte's 90 million monthly active user ID graph. Adjacent products include seeO2now (IoT CO2 sensor subscription, ¥4,980/month) and Railcast Ads, jointly launched with JR West Japan in May 2026 to combine railway ridership data with weather context.

Le Grand monetizes through a hybrid revenue model: professional services (project and retainer consulting engagements for enterprise clients), recurring SaaS subscriptions (SmartUX, seeO2now), usage-based API revenue (TNQL paid tier), and platform revenue (weathermarketing.net® via ParaWorks reseller and direct integrations). Go-to-market is multi-modal: direct enterprise sales for consulting, self-serve PLG for SmartUX and TNQL API, and channel/reseller distribution for weather advertising. A Los Angeles Design Center supports foreign companies entering Japan and Japanese companies expanding abroad. The company is privately held with no disclosed institutional investors or funding rounds, operated by its founder-management team with 11–50 employees.
