SulAmerica was founded in 1895 and is one of the three largest health insurance providers in Brazil, offering coverage to more than 7 million people across the country. The company was acquired in 2023 by Rede D'Or (BVMF: RDOR3), the largest hospital conglomerate in Brazil, strengthening its market position by integrating health plans with hospital services.

Leadership vision

When Enter first visited SulAmerica, it was positively impressed by the company's digital maturity and its pioneering vision for using artificial intelligence across all its business areas.

SulAmerica's legal department stood out by embracing digital transformation early on, demonstrating a genuine commitment to innovation and operational excellence. To achieve this, the legal team had a clear objective: to enrich its database to better understand the reasons behind lawsuits against SulAmerica and how to argue their cases more effectively.

Given this scenario, the legal team’s management decided to establish a partnership with Enter, allowing its artificial intelligence to read and interpret each lawsuit filed against the company, identifying winning defense strategies. This initiative positions SulAmerica as a benchmark in the practical application of AI in the Brazilian legal market.

Enter's AI generating actionable insights

Enter's AI platform analyzed more than 30,000 lawsuits filed against SulAmerica and reviewed over 500,000 documents—cover to cover—to structure data that would support decision-making.

Right away, several strategies emerged to address predatory litigation, among them answering medical prescriptions that lack proven scientific evidence.

1. The same lawyers were behind most lawsuits

A single lawyer was responsible for filing more than 1,000 lawsuits against SulAmerica, indicating a coordinated effort rather than just isolated claims.

Enter's AI identified dozens of lawyers who, individually, filed more than 50 lawsuits against the company within a short period.

2. Recurring Patterns of Fraud in Medical Prescriptions

  • Many lawsuits featured nearly identical medical reports, often issued by the same professionals.

AI-powered lawsuit answers

To ensure the consistent application of its new legal strategy, SulAmerica partnered with Enter to create a robust database containing all relevant information, especially in light of the fraud crisis that has plagued the supplementary health sector in recent years.

With this new database, enriched with information essential to defending SulAmérica’s interests, Enter began producing structured documents — fed by data extracted from SulAmérica's evidence database — to support SulAmérica's legal department and its law firms as they write, review, and refine their filings.

Enter’s AI analyzes every document in the lawsuit and runs a thorough cross-examination against SulAmérica’s internal evidence drawn from the new database. As a result, it can structure a document that:

  1. Detects abusive litigation
  2. Flags every type of fraud
  3. Surfaces for the attorney the legal inputs and arguments available for each plaintiff claim, so SulAmérica’s legal team applies its own judgment in its answer

Next steps

SulAmérica’s legal department has already redefined its legal strategy in the health sector. The company now wants to consolidate its data-driven approach to litigation to maximize its operational efficiency metrics through Enter’s AI

"Enter empowers SulAmérica's legal team, bringing data to the center of strategic decision-making — and this is just the beginning"
