How to Draft a Shareholders’ Agreement for Your Startup in Spain: A Strategic Guide for Expats

For an expat entrepreneur, landing in the Spanish ecosystem involves more than just understanding the local market or securing a Golden Visa. While the initial focus is often on the Notary and the Public Deed of Incorporation (Escritura de Constitución), seasoned founders know that the real "operating system" of a company is not found in the official bylaws registered at the Registro Mercantil. It is found in the Shareholders’ Agreement (SHA) or Pacto de Socios.

When considering how to draft a shareholders’ agreement for a startup in Spain, one must understand that Spanish Corporate Law (Ley de Sociedades de Capital) provides a rigid framework that often fails to address the dynamic needs of a high-growth technology company. The SHA acts as a private contract that sits alongside the official bylaws, offering the flexibility needed to manage founder relationships, investor expectations, and future exit strategies without the constraints of public administrative bureaucracy.

The Jurisdictional Challenge for Foreign Founders

Expats often arrive with legal templates from Delaware or the UK, assuming they can be "translated" into the Spanish context. This is a common strategic error. A Shareholders’ Agreement in Spain must be harmonized with the Ley de Sociedades de Capital (LSC). While the SHA is a private document, any clause that directly contradicts the LSC may be difficult to enforce against third parties or could lead to internal litigation if not drafted with precision.

The primary goal is to create a document that governs the internal "rules of the game." This includes how decisions are made, how equity is protected, and what happens when a founder decides to move on. For those who are also focusing on the technical side of their launch, such as web design for video game studios or other specialized niches, having a robust legal foundation is what allows the creative and operational work to flourish without the looming threat of governance disputes.

Defining Governance and Reserved Matters

In a standard Spanish Sociedad Limitada (S.L.), decisions are typically made by a simple majority. However, for a startup with multiple founders or early-stage investors, this is rarely sufficient. When you begin to figure out how to draft a shareholders’ agreement for a startup, the "Reserved Matters" section becomes your most powerful tool. These are specific actions—such as pivoting the business model, taking on debt over a certain threshold, or selling the company—that require a qualified majority (e.g., 75% or 80%).

This structure prevents a single majority shareholder from making unilateral decisions that could jeopardize the minority's interests. It is particularly relevant for expats who might be managing operations from different locations, perhaps while expanding your digital presence in El Ejido or managing remote teams across Europe. Establishing these thresholds early prevents "founder paralysis" where no decision can be made, or conversely, a "founder coup" where one party is sidelined.

Equity Protection: The Necessity of Vesting and Buy-Backs

Perhaps the most critical technical component of a Spanish SHA is the vesting schedule. In the startup world, equity is earned through time and contribution. If a founder leaves the project after six months but retains 30% of the equity, the "dead cap table" can make the company uninvestable for future VC rounds. In Spain, we implement this through "Good Leaver" and "Bad Leaver" clauses.

A "Good Leaver" (someone leaving due to illness or an agreed-upon departure) might keep their vested shares but be forced to sell the unvested ones at fair market value. A "Bad Leaver" (someone who breaches the agreement or competes against the company) is usually forced to sell all their shares at a nominal price (e.g., 1 Euro). Drafting these clauses requires a deep understanding of Spanish labor law and civil contracts to ensure they are not deemed "leonine" or abusive by a Spanish court. This level of protection is essential whether you are launching a complex SaaS or a specialized e-commerce for organic products, where the founder's specific expertise is the company's primary asset.

Managing Liquidity: Drag-Along and Tag-Along Rights

A Shareholders' Agreement must anticipate the end of the journey. For an expat founder, the "Exit" is often the ultimate goal. Two clauses are non-negotiable here:
1. Drag-Along Rights: This allows a majority of shareholders who want to sell the company to "drag" the minority shareholders into the sale. This is vital because most buyers want 100% of the company and do not want to deal with a disgruntled 2% shareholder blocking the deal.
2. Tag-Along Rights: This protects minority shareholders. If a majority shareholder finds a buyer for their stake, the minority shareholders have the right to "tag along" and sell their shares on the same terms and at the same price.

Without these clauses, you risk being trapped in a company you no longer control or, conversely, being unable to sell a company you spent years building. These mechanisms are standard in international hubs and are increasingly common in regional Spanish business centers and even in European markets like Vicenza, where cross-border investment is frequent.

Non-Compete and Exclusivity in the Spanish Context

Spanish law is particularly protective of workers' rights, and this extends to founders who are often also employees or directors of their own companies. When drafting the SHA, non-compete clauses must be reasonable in terms of geography and time (usually not exceeding two years) and must often be tied to specific financial compensation to be fully enforceable under Spanish jurisprudence. For an expat, this is a double-edged sword: you want to protect your company from a departing partner, but you also need to ensure your own professional mobility is not illegally restricted.

Conflict Resolution: Beyond the Spanish Courts

The Spanish judicial system, while reliable, can be slow. For a fast-moving startup, a litigation process that takes three years is effectively a death sentence. Therefore, an expertly drafted SHA often includes an arbitration clause. Choosing the Corte de Arbitraje de Madrid or a similar body allows for faster, more technical resolutions. Furthermore, for expat founders, the agreement should clearly state the language of the proceedings—usually English—to avoid costly translation errors and ensure all parties fully comprehend the legal nuances during a dispute.

Strategic Implementation

Drafting the Pacto de Socios is not a one-time administrative task; it is a strategic exercise in risk management. It requires balancing the "honeymoon phase" of a new venture with the cold reality of potential future conflicts. As an expat, your SHA is your primary defense against the complexities of a foreign legal system. It provides the certainty that investors require and the stability that founders need to focus on scaling their operations.

At OUNTI, we understand these complexities because we have lived them. Our agency was founded by expats who, since 2013, have navigated the intricate bureaucratic and linguistic landscape of Spain. We know that the legal foundation is only half the battle; the other half is the execution of your vision in the digital space. If you have secured your governance and need a high-performance web platform to launch your project, we can help you develop the digital tools you need, allowing you to focus entirely on the strategic management of your new Spanish venture.
