Startups and the Law: What Every Entrepreneur Needs to Know

Corporate · By Woshington Luiz dos Reis · Mar 10, 2025

Brazil has established itself as one of the most promising countries for startup growth, with more and more entrepreneurs betting on innovation and new business development. Despite the opportunities, however, a startup’s legal structure is one of the decisive factors in its success or failure.

Many entrepreneurs launch their startups focused only on product development and customer acquisition, leaving aside corporate formalization, intellectual property protection and the legal security of investments. This neglect can lead to disputes between partners, loss of capital and even prevent the business from scaling.

So for a startup to grow safely and be able to attract investors, entrepreneurs must understand the main legal aspects involved in structuring and running the business.

The Biggest Legal Risks for Startups

Without proper legal planning, startups may face a number of problems that threaten their continuity. The main risks include:

  • Disputes between partners: The lack of a well-defined agreement can lead to disputes over equity, roles and profits.
  • Loss of intellectual property: Without trademark and patent registration, the startup’s innovation can be copied.
  • Partners leaving without vesting: Partners may leave the business taking a significant share of the company without having contributed proportionately.
  • Lack of data protection: Startups that collect user data without complying with the LGPD may be penalized.
  • Unsecured investments: The lack of well-structured investment agreements can drive investors away and create financial uncertainty.

Ignoring these risks can compromise growth, fundraising and even the startup’s survival.

Essential Legal Aspects for Startups

For a startup to grow with legal certainty and gain credibility in the market, entrepreneurs should take the following steps:

Choosing the Corporate Structure

Choosing the right corporate structure is one of the first steps to setting up a startup properly. Each format has its own tax implications, liabilities and rules.

  • Limited Liability Company (LTDA): The most common structure for early-stage startups, as it allows equity to be divided into quotas and involves less red tape.
  • Corporation (S.A.): Ideal for startups seeking significant investment and rapid growth.
  • Partnership Agreements: Used for pilot projects or MVPs (Minimum Viable Products) before a company is formally incorporated.

The wrong choice can create tax problems and make fundraising harder. That is why legal advice is essential to define the best structure for the business.

Protecting Intellectual Property

One of a startup’s greatest competitive advantages is its technological and intellectual innovation. Without proper legal protection, however, the business can be copied or exploited by third parties.

  • Trademark Registration: Secures exclusive rights to the startup’s name and visual identity.
  • Patents: Protect technologies, inventions and innovative processes.
  • Copyright: Applies to software, content and materials developed by the startup.
  • Non-Disclosure Agreements (NDAs): Essential to protect strategic information in negotiations and partnerships.

A lack of protection can cost the startup its competitive advantage and cause irreversible losses.

Vesting Agreements for Partners and Employees

Vesting is an agreement that sets rules for partners or key employees to acquire equity gradually. It prevents someone from leaving the company with a large share of the capital without having truly contributed to the growth of the business.

  • Founding partners: Vesting can establish that equity is earned over time, encouraging them to stay with the business.
  • Key employees: Startups that offer equity should set clear criteria to avoid future disputes.
  • Exit rules: If a partner leaves before the agreed period, their quotas can be redistributed among the other members of the startup.

This model is widely used in Silicon Valley and is already a recommended practice for Brazilian startups that want to grow safely.

Compliance with the LGPD (Brazilian General Data Protection Law)

Startups handle large volumes of user data every day, whether through platforms, apps or digital services. The LGPD imposes strict rules on how this information is collected, stored and shared.

  • Obtain users’ consent before collecting personal data.
  • Make your privacy policy and terms of use clear.
  • Protect sensitive information with encryption and access controls.
  • Avoid misuse of data that could lead to penalties and loss of customer trust.

Failure to comply with the LGPD can lead to fines of up to R$ 50 million, as well as administrative sanctions and lawsuits.

Investment Agreements: Protection for Startups and Investors

Raising capital is one of the biggest challenges for startups. Every investment, however, must be formalized with proper agreements, providing security for both entrepreneurs and investors.

The main investment agreements include:

  • Convertible Loan: The investor lends money to the startup and may convert it into equity in the future.
  • SAFE (Simple Agreement for Future Equity): An agreement that allows the investor to receive equity in the future without setting a valuation at the time of the investment.
  • Equity Crowdfunding: A collective fundraising model regulated by the CVM (Brazilian Securities and Exchange Commission).

Without well-drafted agreements, the startup may face disputes over shareholdings and investors’ rights in the future.

Conclusion: Is Your Startup Legally Secure?

The startup market is dynamic and highly competitive. A well-planned legal structure is essential to ensure security, attract investors and avoid future disputes.

If you are an entrepreneur and want your startup to grow on solid, secure ground, make sure you are covering the main legal aspects:

  • A well-defined corporate structure
  • Protected intellectual property
  • Vesting for partners and employees
  • LGPD compliance
  • Investments formalized with proper agreements
