What 弁護士ドットコム（株） does

Bengo4.com, Inc. (弁護士ドットコム株式会社) is a Tokyo-headquartered, publicly traded legal technology company founded in 2005 that operates Japan's largest network of legal service platforms. Its core products span a consumer-facing lawyer portal (BENGO4.COM) with 29,000+ registered lawyers representing more than 60% of Japanese lawyers as of July 2024, a tax-accountant matching service (ZEIRI4.COM) with 6,900+ registered accountants and 1.8M+ monthly users, a corporate legal media portal (BUSINESS LAWYERS) with 130,000+ members, a legal news media property (BENGO4.COM NEWS), a high-end career placement service for legal professionals (BENGO4.COM CAREER), and a digital document tool for lawyers (Bengo Kakumei / 弁護革命).

The technology base combines a proprietary legal database and content library with AI-driven services, headlined by LegalBrain Agent (an integrated legal AI agent for legal text and structured information) and a Hankeihisho (case-precedent secretary) integration. The flagship enterprise product, CloudSign, is Japan's first cloud-based electronic signature service confirmed by the competent authority as compliant with the Electronic Signature Act and holds the No.1 domestic market share for electronic contract tools.

Revenue is generated through a hybrid model: recurring subscriptions (CloudSign enterprise contracts, BENGO4.COM professional listings, BUSINESS LAWYERS media, LegalBrain AI services), transaction-based matching and placement fees (ZEIRI4.COM tax-accountant matching, BENGO4.COM CAREER), and advertising. Distribution combines a self-serve, SEO-driven web platform for consumers and professionals with an enterprise field-sales motion for CloudSign targeting major corporations and financial institutions, evidenced by adoptions at Mizuho Trust Bank, Sumitomo Mitsui Trust Bank, Mitsubishi UFJ Trust Bank, and Resona Bank.
