Enter Raises $35M in Latin America’s Largest AI Series A with Founders Fund and Sequoia
On a mission to position Brazil as a global leader in Artificial Intelligence, Enter announced the closing of a $35 million Series A, co-led by Founders Fund and Sequoia Capital, marking the largest AI-focused investment recorded in Latin America to date.
This landmark investment reflects the broader transformation occurring across Latin America’s venture capital ecosystem. According to Cuantico VP’s “Latin America Venture Capital Report 2025,” the region experienced a remarkable 26% growth in startup funding in 2024, outpacing Europe’s 7% rise and defying Southeast Asia’s 34% decline.
Six months after completing its Seed round with Sequoia Capital, Enter —the Brazilian startup that uses artificial intelligence to assist corporations in their legal defenses— closed this new capital raise with a post-money valuation of $364 million, attracting another giant of American venture capital.
The round was co-led by Founders Fund, the venture capital firm founded in 2005 by Peter Thiel, recognized for being one of the first investors in Facebook and SpaceX, alongside Sequoia, which increased its participation beyond its pro rata share. The operation also included participation from ONEVC and Atlantico.
This marks Founders Fund's return to the Brazilian market since 2016, when it led Nubank's Series C. Notably, the American firm debuts in the legaltech sector with this investment in Enter.
A Market of Massive Opportunity
The context driving this investment is extraordinary: Brazil hosts 80 million active lawsuits, nearly 8 times the volume of the United States. Litigation has become a structural cost for large enterprises, draining billions of dollars from their balance sheets every year.
Founded in 2023, Enter addresses this critical problem where high costs associated with consumer lawsuits can represent between 4 and 5 times corporate net profit.
Comprehensive Technological Solution
The company developed artificial intelligence agents that manage the complete lifecycle of lawsuits: from initial intake and fraud detection to drafting defenses and recommending settlements.
Enter's AI agents also provide assistance in preparing legal appeals, participating in hearings, and calculating judicial costs, delivering higher success rates and millions in savings for their clients.
"We're building a comprehensive operating system for litigation. All workflows will be integrated into this product, which we've named EnterOS," explained Mateus Costa-Ribeiro, CEO and founder of Enter, in statements to Brazil Journal.
Exceptional Commercial Traction
Since its initial round in March, Enter experienced substantial growth. The startup onboarded 10 new corporate clients, reaching more than 15 publicly traded companies, including giants like Nubank, Itaú, Santander, Mercado Libre, LATAM, Magazine Luiza, Banco Pan, and Airbnb.
The platform projects processing more than 250,000 new cases in 2025 alone, managing approximately 30% of all consumer processes against their clients, a figure that increases significantly in commercial relationships established for more than a year.
"When we start commercial relationships, we typically capture 15% of the client's demand. In 12 months, this participation expands to nearly 60%," the founder detailed.
Although Enter doesn't disclose its total revenue, Mateus revealed that the average contract with its publicly traded clients totals more than $700,000 annually, projecting annual revenue of approximately $10.9 million.
Global Expansion Vision
The new funding round will drive expansion toward larger-scale corporations, requiring significant upfront investments in operational and technological capabilities.
Costa-Ribeiro outlined a three-phase growth strategy: consolidating as the reference platform for consumer cases in Brazil, expanding into adjacent opportunities like labor litigation and claims before regulatory agencies, and internationalizing operations within a 3-4 year horizon.
The founding team is completed by Michael Mac-Vicar, former CTO for 12 years of Brazilian gaming unicorn Wildlife, and Henrique Vaz, who worked at Tesla and served as CMO of Wildlife.
