Software Development 千代田区, 東京都 51–200 employees Founded 2018 Privately Held

Lisse builds AI-driven legal support tools for Japanese SMEs, combining lawyer expertise with machine learning to automate contract review and compliance work. The tech stack spans Python, Go, Django, FastAPI, and React across both AWS and GCP—a polyglot, cloud-native architecture typical of companies doing generative AI research. Active R&D into generative AI and a contract-review AI product suggest the platform is shifting from template-based tools toward automated legal analysis.
