What Lisse does

Lisse Co., Ltd. (株式会社リセ) is a Tokyo-based legal technology company founded in 2018 by Miki Fujita, a former partner at Nishimura & Asahi. The company sells an AI contract review suite to Japanese corporate legal departments, anchored by three subscription products: LeCHECK, an AI contract review cloud that performs clause-by-clause risk identification, modification proposal generation, and missing-clause detection across Japanese and English contracts; LeFILING, a Google Drive-based contract lifecycle management service that automates storage, organization, and expiration tracking of executed agreements; and LeTRANSLATE, a Microsoft Word add-in that delivers AI-powered Japanese-English legal document translation. The AI layer is attorney-supervised and continuously updated against current Japanese statutes and case precedents, and integrates NLP-driven classification with growing generative AI capabilities. Underlying integrations include Google Drive (LeFILING) and Microsoft Word (LeCHECK/LeTRANSLATE).

The company operates a horizontal go-to-market motion targeting primarily Japanese SMEs and mid-market legal departments that lack specialized in-house counsel, supplemented by enterprise sales for larger accounts. Demand generation is driven by a prolific free webinar and seminar program (often dozens of sessions per month) covering NDA, service agreement, sales contract, freelance law, and cross-border topics, frequently co-hosted with strategic partners such as KiteRa, Money Forward, Authence Consulting, SocialWire, REGAL CORE, AsiaWise, and Anderson Mori & Tomotsune. The conversion path moves prospects from free trial and gated whitepaper downloads to demo requests, online consultations, and subscription contracts with tiered pricing including a Professional plan. Lisse is also actively recruiting resellers and referral partners. Lisse is privately held and headquartered at WeWork KANDA SQUARE in Chiyoda-ku, Tokyo, with 51–100 employees.

Lisse's business model is recurring subscription SaaS across the three products, with the funnel sustained by content marketing (whitepapers, case studies, blog), webinars, and partner co-marketing. As of September 2025, Lisse reported over 4,500 corporate customers adopting its AI legal solutions. The company has raised approximately ¥2.14 billion in Series C funding across two closes in 2025 — ¥1.14B led by MPower Partners Fund in April 2025 and ¥1.0B from Japan Post Spiral Regional Innovation Fund, NTT DOCOMO Ventures, Aozora Corporate Investment, and SB C&S in November 2025 — bringing total funding to an estimated ¥3.5B+ across earlier rounds. CEO Miki Fujita also serves as Representative Director of the General Incorporated Association AI Legal Tech Association, anchoring Lisse's category leadership position in the Japanese legal AI market.

• Bengo4.com: Japan's largest legal tech platform (operates Bengo4.com and legal services marketplace). Listed as a Series B/C investor in Lisse and directly comparable as a Japanese AI/digital legal services provider targeting corporate and consumer legal needs.
• LegalForce: Japanese AI contract review cloud service (formerly LegalForce). Directly competes with LeCHECK in Japan, offering AI-powered contract review for SMEs and enterprise legal departments using similar clause-by-clause analysis.
• GVA TECH: Japanese legal tech company providing AI contract review (AI-CON) and corporate legal services. Targets the same SME and mid-market legal departments in Japan with comparable AI contract review offerings.

Emerging players

• Spellbook: Canadian AI legal assistant for contract drafting and review using GPT-class models. Comparable AI-first approach to contract review with cross-border capabilities that could localize for Japan.
• Evisort: AI contract lifecycle management platform specializing in document analysis and clause extraction. Comparable AI-native approach to contract review, recently scaled through enterprise channels; potential expansion into Japan could compete with LeCHECK's AI review positioning.
