Sourire

What Sourire does

Sourire Co., Ltd. (スリール株式会社) is a Tokyo-headquartered management consulting and training firm founded in November 2010 by Atsuko Horie. The company specializes in women's career advancement (女性活躍), DEI promotion, diversity management training, and work-life balance programs targeting large Japanese corporations, universities, and local government entities. Its service portfolio spans corporate consulting (current-state analysis, DEI roadmap development, committee facilitation), structured training programs (Ikuboss Boot Camp, dual-career training for returnees and supervisors, management training), proprietary diagnostic tools (Women Advancement Survey, Life Career Orientation Type Diagnosis), an annual Career-Life Conflict White Paper research publication, and the Work & Life Internship — Japan's first corporate student internship program focused on dual-income household experiences, launched in collaboration with Osaka Gas in 2015.

The company's products are delivered through three primary commercial channels: (1) professional-services consulting and training contracts with corporate HR and management teams (quote-based pricing negotiated individually), (2) a one-time/perpetual-license online training video platform (online.sourire-heart.com) that self-serves mid-market buyers, including example SKUs such as a two-video return-to-work set priced at 495,000 yen on campaign (660,000 yen list), and (3) prefectural and municipal government contracts for life-design education programs aimed at university students and young adults. The underlying technology consists of proprietary training curricula, survey-based diagnostic frameworks, and content libraries built and refined over 15 years, with no disclosed AI/ML or software platform infrastructure.

Sourire's go-to-market is enterprise field sales — direct outreach to HR departments of large Japanese corporations, supplemented by HR-targeted webinars, blog content (corporate site and Note.com), earned media coverage, and event participation (WOMAN EXPO, EO D&I Summit). Over its 15-year operating history the company reports training more than 20,000 participants, with at least one senior consultant touching 100+ companies annually. In July 2026 Sourire refreshed its executive officer structure, adding three executive officers alongside founder-CEO Horie to support business growth and organizational foundation strengthening.
