$1.2 billion.
That is the latest valuation for Enter, the Brazilian legal AI company that raised $100 million in a round led by Founders Fund, with Sequoia and Ribbit also joining.
The headline number is not the most explosive part. The pace is: seven months ago Enter was valued at $350 million; now it is at $1.2 billion, nearly four times higher.
The more interesting point is what Enter is building: AI for companies that have to fight lawsuits in bulk.
Brazil's unusual legal market
Why Brazil?
Brazil has roughly 80 million active lawsuits. The United States is in the tens of millions; Brazil is about eight times larger. That is not because Brazilians simply love litigation. It is because the structure of the legal system makes consumer lawsuits cheap to file and relatively low-risk to lose, leaving banks, telecom operators and retailers exposed to hundreds or thousands of small claims every day.
The traditional answer has been blunt: large companies employ hundreds of lawyers who respond to those cases like a production line.
Enter's answer is simpler: let AI draft the response.
The platform reads each complaint, extracts the key facts, combines them with a company's contracts, prior rulings and product data, then drafts a defense that a lawyer can review and submit to court.
That may sound like lightweight "GPT writes legal documents" software. Enter's customer list suggests something much heavier:
- Itaú, Santander, Nubank and BMG: major Brazilian banks
- Mercado Livre: Latin America's answer to Amazon
- Airbnb and Vivo: multinational and regional giants
The company expects to handle more than 250,000 lawsuits in 2026. That is close to 700 defenses a day, a volume that law firms cannot absorb without automation.
An unusually credentialed founder
Mateus Costa-Ribeiro has an outlier resume:
- He became Brazil's youngest practicing lawyer at 18
- He passed the New York bar exam at 20
- He graduated from Harvard Law School
- He won a full scholarship to Stanford's MBA program, then turned it down to return to Brazil and start a company
Enter was founded in 2024. The founder story would not look strange in Silicon Valley. In Latin America, it is far rarer.
What is even rarer is the market Enter chose. Founders Fund and Sequoia backing a "South American legal AI" company at the same time says something clear: top U.S. venture firms think emerging-market AI moats will not look like Silicon Valley moats.
A different playbook from Harvey and Legora
Legal AI already has several high-profile names. Harvey reportedly reached an $11 billion valuation earlier this year, while Legora tripled its valuation in five months.
But Harvey and Legora sell AI for law firms: Magic Circle and Big Law workflows, high contract values, long decision cycles and advisory work.
Enter sells bulk litigation tooling to corporate legal departments and judicial insurance companies. The average contract may not be as rich, but the volume is large, the pain is direct and each handled lawsuit can become a billable unit.
Brazil's legal market also does not map neatly onto the Big Law model. It needs software that can process tens of thousands, even hundreds of thousands, of cases at scale. Harvey cannot simply take this market; the product shape is wrong.
The valuation speed is the real signal
Seven months, from $350 million to $1.2 billion, roughly four times higher.
That pace would have looked wild in 2024. In 2026 it looks closer to the new normal. AI valuation cycles have compressed to six to nine months: Sierra went from zero to $15.8 billion in two years, Cursor from zero to $50 billion in three years, and Cognition multiplied its valuation sixfold in 13 months.
Enter is another data point in that sequence. Its difference is that it is not a Silicon Valley narrative company. A São Paulo legal AI startup winning repeated commitments from Founders Fund and Sequoia suggests top VCs are now willing to pay a premium for regional, deeply vertical, high-barrier AI businesses.
Where does the next version appear? Compliance AI in India? Health insurance review AI in Japan? No one knows yet. But Enter has proved one thing: the most profitable AI businesses may not be in California, but in countries weighed down by litigation, compliance and bureaucracy.
