Brazilian Legal AI Startup Enter Triples Valuation to $1.2 Billion in New Round
Latin America’s legal AI race just produced its most consequential milestone yet. Enter, a Brazilian AI legal startup, has tripled its valuation to $1.2 billion in a new round of funding, vaulting it into the upper ranks of artificial intelligence companies in Latin America. The Brazilian legal AI startup Enter valuation $1.2 billion round a $100 million raise led by Founders Fund with participation from Sequoia Capital and Ribbit Capital comes less than eight months after the company was valued at $350 million, making it one of the fastest valuation climbs in the region’s tech history.
Built for Brazil’s Litigation Mountain
Enter builds AI agents that handle mass litigation the kind that fills up Brazil’s court system every day. Its software reads each lawsuit, pulls in case-specific data, and drafts a defence the legal team can file, a use case rare for legal AI since most tools focus on contracts and research. Enter is built for the cases that get filed by the thousand against banks, retailers, and telecoms. The market context is staggering. Brazil has roughly 80 million active lawsuits about eight times the US caseload and Enter expects to process more than 250,000 cases this year. Its client list includes Itaú, Santander, Nubank, Mercado Livre, Airbnb, BMG, and Vivo.
Founder Mateus Costa-Ribeiro’s profile is itself a statement of intent. He became Brazil’s youngest practising lawyer at 18, finished Harvard Law, passed the New York Bar at 20, and left a fully funded Stanford MBA seat to start the company. Enter’s first big round closed in September 2025 at $350 million, co-led by Founders Fund and Sequoia marking Sequoia’s first Brazil bet since it backed Nubank more than a decade ago. The Brazilian legal AI startup Enter valuation $1.2 billion milestone places it in clear company: Harvey, the US leader in legal AI, was last valued at $11 billion in March, while Legora hit $5.5 billion that same month. The next test is whether Enter’s mass-litigation model, which has unmistakable product-market fit in Brazil, can travel to Mexico, Spain, or Portugal courts that share the same structural backlog. As reported by Bloomberg, investors are clearly paying for that optionality.
