Brazil'S New Legal AI Unicorn

São Paulo-based AI legal startup Enter (@getenter_ai) has raised $100 million in a round led by Founders Fund, with participation from Sequoia Capital and Ribbit Capital, tripling its valuation to $1.2 billion in under eight months. The deal confirms Enter as one of Latin America's most valuable AI companies and signals growing investor appetite for legal technology built on structurally oversized litigation markets.

A Market Built for AI

The scale of Brazil's legal system is the foundation of Enter's pitch to investors. Brazil carries nearly 80 million active lawsuits, eight times the US caseload, with free digital filings fueling an avalanche of consumer cases against banks, retailers, and airlines that elsewhere would be resolved through routine customer support. That volume creates both the problem and the data advantage. Enter processes over 250,000 new cases annually for clients including Itaú, Santander, Mercado Livre, Nubank, and Airbnb. The company's AI agents manage the complete lifecycle of lawsuits, from initial intake and fraud detection to drafting defenses and recommending settlements.

Founder Credentials and Valuation Context

Founder Mateus Costa-Ribeiro became Brazil's youngest practicing lawyer at 18, graduated from Harvard Law, passed the New York Bar at 20, and left a full-ride Stanford MBA to build Enter, which he launched in 2023. The company has since repatriated more than 15 hires from US and European firms, leaning into the argument that the best talent for this problem is the talent closest to it.

The valuation trajectory ran from $350 million in September 2025 to $1.2 billion in May 2026. Harvey, the US-based AI legal platform backed by Sequoia and OpenAI, was valued at approximately $3 billion in its most recent disclosed round, while Enter at $1.2 billion sits below those comparable companies on absolute valuation. However, the velocity of its valuation growth, tripling in eight months, is faster than either of the Western comparables over equivalent periods. Legora, a European legal AI startup, was in talks to raise at a $6 billion valuation as recently as February 2026.

Founders Fund partner Matias Van Thienen has previously described Enter's vertically integrated approach as one that "not only solves pain for enterprises but also alleviates a systemic drag on the economy," pointing to excess litigation as a more urgent problem in Brazil than anywhere else. The fresh capital is expected to accelerate case volume, deepen the data flywheel, and support Enter's push into adjacent litigation categories including labor disputes and regulatory agency proceedings.
