Enter

Introduction

Enter is a Brazilian AI-native litigation platform (branded EnterOS), founded in 2023 by Henrique Vaz, Mateus Costa-Ribeiro, and Mike Mac-Vicar, and headquartered in São Paulo. Its AI agents run high-volume civil and labor litigation end-to-end for large Brazilian companies — reading case files, detecting fraud and procedural irregularities across more than 30 automated checks, and producing jurimetric analysis to inform defense strategy, with human attorneys making final strategic calls. In May 2026 the company announced a Series B round of over $100 million led by Founders Fund, with Ribbit Capital, Sequoia Capital, ONEVC, Atlantico, and Kaszek also participating, at a reported $1.2 billion valuation — becoming, per the company's own announcement, Latin America's first AI unicorn.

Legal Research

Enter is not a general legal research tool; its jurimetric analysis (conviction averages, appeal reversal rates) is purpose-built to inform litigation strategy on the specific case types it handles, not broad case-law search.

Contract Analysis

Contract review is not Enter's focus; it extracts information from contracts, audio, video, and statements as evidentiary inputs to litigation defense rather than as a standalone contract-review product.

Document Drafting

Enter assists legal teams in structuring legal texts using information extracted from its case database, supporting drafting within the litigation-defense workflow rather than general-purpose document generation.

Legal Translation

Enter does not advertise a dedicated legal translation feature; it operates natively in Portuguese for the Brazilian market.

Predictive Analytics

This is a genuine strength: jurimetric analysis of conviction averages and appeal reversal rates, plus real-time monitoring and AI summaries of judicial decisions, to predict likely outcomes and prioritize defense strategy across high case volumes.

Pricing

Enter does not publish pricing; as an enterprise platform sold to large companies' legal departments, interested organizations need to contact the company directly.

User Reviews and Ratings

Enter does not have a visible G2 or Capterra listing with published ratings, though the company cites client testimonials describing agile, real-time-corrected legal defense strategies built on its evidence-scoring approach.

Verdict

Enter is one of the most well-capitalized and highest-scale legal AI platforms in this review after its 2026 unicorn round, but it is narrowly built for high-volume Brazilian civil/labor litigation defense rather than a general-purpose legal AI tool — a strong fit for large Brazilian companies with high case volumes, not relevant outside that market and use case.
