Cloud Sign

What Cloud Sign does

Cloud Sign (クラウドサイン) is a Japanese cloud-based electronic contract platform operated by Bengo4.com, Inc., designed to replace paper-based and hanko (seal) stamping workflows with legally compliant digital signatures. The platform serves over 2.5 million companies and has processed more than 40 million cumulative documents, holding the No. 1 domestic market share in Japan's electronic contract tool market per Fuji Kimera Research's FY2024 vendor share ranking. Cloud Sign's core offering combines electronic signature with legally recognized timestamps compliant with Japan's Electronic Signature Act, supplemented by a modular product portfolio including Cloud Sign Review (AI-powered contract risk analysis), Cloud Sign Kanri (AI-enhanced contract lifecycle management), Cloud Sign SCAN (paper digitization), Cloud Sign NOW (in-person tablet signing), and industry-specific solutions for healthcare/elderly care (Cloud Sign for 介護DX) and government (LGWAN-registered).

The company operates a hybrid business model pairing a freemium self-serve tier (free plan with 2 transmissions/month and 1 user) with paid B2B plans (Light at ¥12,100/month, Corporate at ¥30,800/month, and Business/Enterprise on contact pricing) plus usage-based per-transmission fees of ¥220. Go-to-market blends self-serve sign-up for SMBs with a dedicated enterprise sales force and channel partners — notably Ricoh Japan for the healthcare/welfare vertical and NTT Docomo for mid-market distribution. The platform integrates with Salesforce, kintone, Microsoft Teams, and a no-code Hub powered by BizteX Connect, and is certified under ISO 27001, ISO 27017, SOC 2 Type 1, and Japan's ISMAP government cloud certification. Data is held in two domestic Japanese data centers.

Cloud Sign has expanded into AI-powered capabilities including automatic contract metadata extraction, risk clause identification, and handwriting recognition, evolving from a pure e-signature service into a broader contract lifecycle management platform. It is operated as a subsidiary brand within Bengo4.com's broader legal-technology ecosystem, which also includes lawyer.com consultations, tax accountant consultations, and BUSINESS LAWYERS. The platform is domestic Japan-focused with no disclosed international expansion.
