Enter

Enter is a São Paulo, Brazil-based legal technology company that develops artificial intelligence agents to assist corporate legal teams with mass litigation management, document analysis, and fraud detection. The platform utilizes a human-in-the-loop model to automate case intake and defense drafting, and is projected to process over 250,000 new legal cases throughout 2025. The enterprise software is utilized by major financial institutions and technology corporations, including Itaú, Nubank, and Airbnb, to securely process sensitive legal documents and reduce overall litigation costs. Following a period of rapid expansion where live revenue grew six times over, the company secured $35 million in Series A funding co-led by Sequoia Capital and Founders Fund, reaching a valuation of $350 million. Originally operating under the name Talisman, the legal technology startup Enter was founded in 2023 by co-founder and CEO Mateus.

Enter is an AI-driven platform that helps large companies enhance the efficiency of their legal teams by performing exhaustive analysis of diverse legal documents—such as audio files, contracts, videos, and bank statements—to detect predatory litigation, verify case validity, and generate ready-to-file legal defenses. This leads to higher litigation success rates and operational efficiency for legal professionals, particularly in high-volume, labor-intensive legal processes. Enter serves major Latin American enterprises like Nubank, C6, SulAmerica, and BMG, addressing complex legal challenges with AI-powered automation integrated into existing Legal ERPs[1][2][3].

Founded in 2023 by Mateus Costa-Ribeiro (a prodigious lawyer with Harvard and Stanford background), Michael Mac-Vicar (former CTO of Wildlife Studios), and Henrique Vaz (a Harvard-trained computer scientist and former Tesla engineer), Enter emerged from the founders’ combined expertise in law, AI, and product development. The idea originated from the need to tackle Brazil’s notoriously complex and litigation-heavy legal market by automating document analysis and legal defense drafting. Early traction includes partnerships with leading Latin American companies and a $5.5 million funding round led by Sequoia Capital and Founders Fund, validating its market potential and technology[3][5][6].

Role in the Broader Tech Landscape

Enter rides the wave of AI adoption in legal technology, a sector ripe for disruption due to its traditionally manual, error-prone, and time-consuming processes. The timing is critical as enterprises face increasing litigation volume and complexity, especially in emerging markets like Brazil, which has one of the world’s most complex legal systems. Market forces such as regulatory pressure, demand for cost reduction, and digital transformation accelerate AI integration in legal workflows. Enter’s approach not only improves legal team efficiency but also alleviates systemic economic drag caused by excessive litigation, positioning it as a potential global leader in legal AI[3][5].

Quick Take & Future Outlook

Enter is poised to expand beyond consumer lawsuits into complex labor disputes and predictive AI that recommends optimal evidence, precedents, and legal arguments. Its continued growth will likely be shaped by advancements in AI explainability, regulatory compliance, and deeper integration with enterprise legal systems. As it scales globally, Enter could redefine how AI shapes legal strategy, making legal processes faster, more accurate, and more cost-effective. This aligns with its mission to make Brazil a protagonist in the AI revolution and to transform the legal industry worldwide[3][5][6].

In summary, Enter leverages cutting-edge AI to empower legal teams with exhaustive document analysis, driving higher case win rates and operational efficiencies in one of the world’s toughest legal markets. Its strong founding team, innovative technology, and strategic investor backing position it for significant impact on the legal tech ecosystem.
