The Brazilian startup Enter reached a market valuation of $1.2 billion, equivalent to about R$ 6.16 billion, in May, consolidating itself as the first Artificial Intelligence unicorn in Latin America. Founded in 2023, the company offers specialized tools to assist companies dealing with legal matters.
Recently, Enter raised over $100 million (approximately R$ 514 million) in a new round of investment, with participation from Sequoia and Founders Fund, investors who already supported the company. This injection resulted in a threefold increase in Enter's valuation.
Legal Technology Features
Enter was conceived by Mateus Costa-Ribeiro and Henrique Vaz, starting its operations in the legal segment. Its technology has the capacity to intervene in various phases of a legal process, covering everything from filing lawsuits and analyzing jurisprudence to identifying fraud in documents and drafting procedural pieces.
Furthermore, the AI systems examine materials attached to cases, such as contracts, audio recordings, videos, and statements, searching for information relevant to the defense.
According to the company itself, Enter's technology provides greater efficiency throughout the entire judicial process cycle, covering everything from case registration and detection of documentary fraud to analysis of legal precedents and suggestion of drafts.
Enter also performs more than 30 checks to identify signs of abusive litigation. In the described operational model, artificial intelligence acts before human intervention; every document is processed by an AI agent before any person participates in the case.
Costa-Ribeiro commented to Bloomberg in May that 'every stage imaginable in a judicial process is first handled by an AI agent before a human enters.'
Enter's trajectory began after Costa-Ribeiro left one of the main law firms in New York to focus on technology. He reported on LinkedIn that this change involved giving up a stable position and a salary considerably higher than that of the new role.
Initial Development
The executive began collaborating with software engineers, learning programming and moving to Stanford. Together with two colleagues, he created a website where users could submit an initial petition in PDF format and receive a suggested defense via email.
He recalls: 'It was September 2023, and I had no idea that that ugly Google Form—the first interface of Enter's product—would turn into the greatest adventure of self-knowledge and growth of my life.'
This initial prototype gave rise to Enter, which in less than two years reached a valuation of $1.2 billion. The news about the Brazilian AI for judicial processes was initially published in Olhar Digital.
