The group's core technology products are the 人事評価ナビゲーター (Human Evaluation Navigator) and 人事管理ナビゲーター (HR Management Navigator) cloud platforms, offered via monthly SaaS subscriptions starting at ¥5,500 per month and targeted at small-to-medium enterprises. These are complemented by proprietary consulting methodologies (NK MBO framework), the Libra hospital management analysis system, KEYbird cost accounting, and a freely published medical supply-demand dataset covering all 330 medical regions in Japan. The firm also operates affiliated tax accountant (税理士法人日本経営) and social insurance labor attorney (社会保険労務士法人日本経営) corporations, providing integrated consulting, accounting, tax, payroll, and HR system services as a bundled offering.

Revenue is generated across five streams: (1) management consulting engagements (project and retainer based) with hospitals, clinics, dental practices, and general businesses; (2) SaaS subscriptions for the Navigator HR platforms; (3) accounting and tax advisory via the affiliated tax accountant corporation; (4) social insurance and payroll outsourcing via the labor attorney corporation; and (5) training and education services including seminars and executive coaching. The go-to-market is sales-led, combining direct enterprise consulting sales with content marketing (resource library, Vitamin M monthly newsletter, YouTube 'Wevery' channel), seminars and webinars, and group-company cross-sell. Distribution is exclusively domestic Japan-focused.
