LegalOn

Introduction

LegalOn Technologies is an AI contract review platform founded in Tokyo in 2017 by two corporate lawyers, Nozomu Tsunoda and Masataka Ogasawara. It launched its first contract-review AI product in 2019 under the name LegalForce, became one of the most widely adopted AI contract-review tools in Japan (used by over 30% of Japan's public companies), expanded to the United States in 2022, and rebranded globally as LegalOn. The company combines AI review with attorney-built playbooks and reports reducing contract review time by up to 85%; it says its platform is now used by more than 7,000 legal teams, including 87% of Fortune 500 companies. LegalOn has raised a reported $200 million in total funding, including a $50 million Series E round in July 2025 led by Goldman Sachs, and in October 2025 acquired Fides, a Sequoia-backed governance platform, extending the product from contract review into entity, board, and governance management.

Legal Research

LegalOn is not a case-law or statutory research tool; it is focused on reviewing an organization's own incoming and outgoing contracts against its playbooks.

Contract Analysis

LegalOn's core strength. Its AI reviews contracts clause-by-clause against attorney-built playbooks tailored to an organization's positions, flagging deviations and risk before a human reviewer engages.

Document Drafting

LegalOn offers drafting-adjacent capability through its Productivity Suite tier (full-lifecycle contract work plus matter management), though its primary strength and reputation are in review rather than drafting from scratch.

Legal Translation

LegalOn does not market a dedicated legal translation feature, despite its Japan-founded, now globally-operating background.

Predictive Analytics

LegalOn provides risk-flagging against defined playbooks rather than predictive modeling of case or negotiation outcomes.

Pricing

LegalOn does not publish pricing publicly. It offers three named tiers — Core Review (for solo attorneys/fractional GCs), Contracting Suite (for in-house legal teams), and Productivity Suite (full lifecycle plus matter management) — priced around team size and required capabilities, available only after booking a demo.

User Reviews and Ratings

LegalOn holds a 5 out of 5 rating on G2 from 8 reviews, with reviewers highlighting large time savings on first-draft review and accurate, consistent risk detection via its Playbooks feature — a small but consistently positive sample.

Verdict

LegalOn is a mature, well-funded, and widely adopted contract-review specialist with a track record spanning both the Japanese and US markets — a meaningfully longer operating history than most AI-native contract-review entrants. Its playbook-driven approach and enterprise pricing make it best suited to established legal teams rather than solo practitioners or very small businesses looking for self-serve, transparent pricing.
