Established by two former corporate lawyers, Nozomu Sunoda and Masataka Ogsawawar, in 2017, the aim of organizing legal requests before and after the Lignon’s target contract review process is to organize legal requests and manage the contract automatically.
According to Daniel Lewis, the Global CEO of Lignon, the company has come out of the team of legal technical startups using the AI for its basis for attorney-casual, expert legal content. He says this base is not like other tools that depend on users to create rules from scratch or use generic AI models that lack the precision necessary for legal work.
“Our approach confirms that the contract reviews are combined with true legal values, making the output more accurate, consistent and practical for legal parties. Also, we have more than 50 attorney-built playbooks, existing workflows have seamless integration, and our solution is to work outside the box, Luis.
Just last week, the startup launched one more tool: Matter Management Legal parties help track contract requests, assign owners, connect the relevant individuals and documents, and cooperate with other departments.
The company also has a non-equity tech partnership with the OpenAI, which gives Lignon access to the chatzipt manufacturer’s advanced larger language models.
“This is a technical cooperation,” Luis explained. “It gives us initial access to their latest models and it is located to work side by side with engineers from our engineers OpenAI [AI] Agents are using great technology, but our owned legal content and skills are being able to be able to. “

In June, Harvey has secured $ 300 million for the AI Series E FundIts evaluation is pushed $ 5 billion and pushing the past year, Cleo also raised $ 300 million, reached the assessment of $ 3 billionThe
Even if the generator transforms the legal industry into AI, Lewis does not think it will replace lawyers. “Technology is not yet there, and is not our view of replacing lawyers,” he said. “Lawyers are still in the driver’s seat. Today, AI cannot do things completely, by definition, only people can do what people can do. And the lawyers who are leaning towards this responsibility – monitoring, editing, practicing the verdict – seeing the most extraordinary leverage from AI now.”
Series C Lignon’s total capital brings up to $ 200 million. Its investors include Softbank Vision Fund, HSG (formerly known as Sikoiya Capital China), Japanese Venture Capital Farm Jafco and MUFG Bank.
