Startup Investment Agreement Spain (Acuerdo de Inversión en Startup)

A Startup Investment Agreement Spain (Acuerdo de Inversión en Startup) is a formal written contract between an investor — typically a business angel (inversor ángel), venture capital fund (entidad de capital-riesgo — ECR), or accelerator — and an early-stage company (empresa emergente) in Spain, documenting the terms under which capital is invested in exchange for equity participation or convertible instruments. The agreement is governed primarily by the Ley de Sociedades de Capital (Real Decreto Legislativo 1/2010 — LSC) and, for qualifying startups, by the Ley 28/2022, de 21 de diciembre, de fomento del ecosistema de las empresas emergentes — Spain's Startup Law — which introduced a specific legal and tax framework designed to attract investment and talent to Spanish early-stage companies.

The Ley 28/2022 (Startup Law) defines an empresa emergente as a company that: (i) has been incorporated no more than 5 years ago (7 years for biotechnology, energy, industrial, and strategic sector companies); (ii) has not distributed dividends or returned capital; (iii) is not listed on a regulated market; (iv) has its registered office (domicilio social) or permanent establishment in Spain; and (v) has an innovative nature — developing a unique product, service, or process with potential for rapid growth, certified by ENISA (Empresa Nacional de Innovación, S.A.) or by the relevant competent body. Certification as an empresa emergente under the Startup Law unlocks significant tax incentives for investors and employees under the Ley 35/2006 del IRPF and Ley 27/2014 del Impuesto sobre Sociedades.

For investors in certified empresas emergentes, the Startup Law increased the personal income tax deduction (deducción en IRPF) for investment in newly created companies — previously 30% capped at €60,000 under the pre-2022 Ley del IRPF Article 68.1 — to 50% of the amount invested (up to €100,000 per year) under the new Ley del IRPF Article 68.1 as amended by the Startup Law. This represents one of the most generous early-stage investment tax incentives in the European Union. Additionally, capital gains from the sale of participaciones in certified empresas emergentes may be exempt from IRPF under conditions established by the Startup Law.

The Startup Law also introduced specific provisions for stock options and phantom shares — employee equity incentive plans (planes de opciones sobre acciones — stock options) are subject to IRPF treatment under Article 17.2.m of the Ley del IRPF, with deferred taxation and a €50,000 annual exemption threshold per employee for qualifying plans in certified empresas emergentes, double the general €12,000 limit.

Startup investment in Spain is typically structured using one of three main instruments: (i) direct equity investment through a capital increase (ampliación de capital) in an S.L. — requiring notarisation before a Notario and Registro Mercantil registration under LSC Articles 295–317; (ii) convertible notes (notas convertibles or préstamos convertibles) — loans that convert to equity at a discount upon a future qualifying investment round (ronda de inversión) or upon predefined conversion triggers; or (iii) SAFEs (Simple Agreement for Future Equity) — instruments introduced from US practice and increasingly used in Spain, though their legal characterisation under Spanish law remains debated — typically treated as préstamos convertibles or as compraventas de participaciones futuras subject to the Código Civil.

The Spanish startup ecosystem — centred in Madrid, Barcelona, and Valencia — has grown significantly following the deployment of EU structural funds and the ENISA gobierno financing programmes. Spain's Asociación Española de Business Angels Networks (AEBAN) and the Asociación Española de Capital, Crecimiento e Inversión (ASCRI) represent the angel investor and venture capital communities respectively, and have published standard term sheets (term sheets) and investment agreement templates that are widely referenced in Spanish early-stage transactions.

Data protection obligations under the Reglamento General de Protección de Datos (RGPD — Reglamento UE 2016/679) and the Ley Orgánica 3/2018 de Protección de Datos Personales y Garantía de los Derechos Digitales (LOPDGDD) are relevant to Startup Investment Agreements in Spain wherever the due diligence process involves the sharing of personal data about employees, founders, or customers. The Agencia Española de Protección de Datos (AEPD) supervises compliance. Where a startup holds significant personal data as a core business asset — as is common in fintech, healthtech, and edtech companies — the investment agreement should include a representation that the startup's data processing activities comply with the RGPD and that the startup has registered its processing activities in the Registro de Actividades de Tratamiento required under RGPD Article 30. The Ley 28/2022 also introduced supportd visa and residence permit procedures for foreign talent in certified empresas emergentes under the modified Ley 14/2013 de Apoyo a los Emprendedores, attracting international founders and engineers to Spain's growing startup ecosystem.

A Startup Investment Agreement Spain is needed whenever an investor makes an early-stage equity or quasi-equity investment in a Spanish empresa emergente or growth company.

The agreement is required when a business angel makes a seed-stage investment (inversión semilla) in a Spanish startup, seeking to benefit from the 50% IRPF deduction under the Ley 28/2022 (Startup Law) — the investment must be in a newly created company (sociedad de nueva creación) or empresa emergente certified by ENISA.

A Startup Investment Agreement is needed when a venture capital fund (entidad de capital-riesgo — ECR) regulated under Ley 22/2014 participates in a Series A, B, or later funding round (ronda de financiación) of a Spanish startup — the agreement documents the investment terms, valuation, and shareholder rights in the company's pacto de socios.

The agreement is necessary when an accelerator or incubator (aceleradora or incubadora) takes an equity stake in a participating startup as compensation for acceleration services — typically 3% to 8% of the company's capital — replacing or supplementing cash payments under a service agreement.

A Startup Investment Agreement is required when convertible instruments are used — a convertible note (nota convertible) or SAFE (Simple Agreement for Future Equity) is issued to bridge financing between two funding rounds, converting to equity at the next qualifying investment event at a pre-agreed discount (typically 10%–25%) or with a valuation cap.

The agreement is needed when a corporate investor (CVC — Corporate Venture Capital) invests in a startup for strategic purposes — accessing new technology, talent, or market access — the investment agreement must address the tension between the corporate investor's strategic objectives and the startup's independence, including provisions restricting the corporate investor's ability to acquire majority control or to access proprietary technology.

A Startup Investment Agreement is also required when the ENISA certification process under the Startup Law has been completed or is pending — the agreement should condition the release of the investment proceeds on successful certification to confirm the investor can claim the 50% IRPF deduction.

Parties in Spain should prepare a Startup Investment Agreement Spain (Acuerdo de Inversión en Startup) proactively rather than waiting for a dispute to arise. Courts interpret agreements based on the written terms rather than oral representations. Under the Ley de Sociedades de Capital (LSC) RDL 1/2010, the Registro Mercantil maintains the register of Spanish companies. The Código de Comercio 1885 governs commercial obligations. The Agencia Estatal de Administración Tributaria (AEAT) administers Impuesto sobre Sociedades (IS) under Ley 27/2014. The Comisión Nacional de los Mercados y la Competencia (CNMC) enforces competition law. The Código Civil governs general contractual obligations under Article 1255. Where the transaction involves regulated activities, prior approval from the relevant authority may be required before execution.

A valid Startup Investment Agreement Spain under the Ley 28/2022 (Startup Law) and the Ley de Sociedades de Capital (RDL 1/2010) must include the following essential elements.

Identification of Parties and Empresa Emergente Status: Full legal details of the investor and the startup company, including NIF, Registro Mercantil details, and confirmation of the company's ENISA certification status (or pending application) as empresa emergente under Ley 28/2022. The certification number and date, or the expected certification timeline, should be referenced to establish the investor's entitlement to the 50% IRPF deduction under the amended Ley 35/2006.

Investment Instrument: Explicit statement of the investment structure — direct equity through a capital increase (ampliación de capital de S.L. under LSC art. 295), convertible note (nota convertible / préstamo convertible), SAFE, or préstamo participativo under RDL 7/1996. For convertible instruments, the conversion trigger events (qualifying investment round, date-based automatic conversion, or IPO), conversion discount (descuento de conversión — typically 10%–25%), and valuation cap (cap de valoración) must be precisely defined.

Pre-Money Valuation and Cap Table: The pre-money valuation for direct equity investments, and the implied valuation at conversion for convertible instruments. The post-investment cap table (tabla de capitalización) showing each socio's percentage ownership should be attached as an exhibit. For S.L. companies, the nominal value of new participaciones and the issue price (valor de emisión) — which may include a share premium (prima de emisión) under LSC Article 299 — must be specified.

Investor Protections and Anti-Dilution: Standard startup investor protections including: information rights (quarterly financials, annual audited accounts, access to management); pro-rata rights to participate in future investment rounds to maintain the investor's ownership percentage; weighted average broad-based anti-dilution protection (protección antidilución de media ponderada de base amplia) in down-round scenarios; tag-along rights (co-venta) and drag-along rights (arrastre) per the pacto de socios.

Founder Vesting and Lock-Up: Provisions requiring founding team members (socios fundadores) to earn their participaciones over a 4-year vesting schedule (typically cliff of 12 months, then monthly vesting), with good-leaver and bad-leaver provisions defining the purchase price for unvested participaciones if a founder leaves the company. Vesting provisions are critical for investors and are increasingly standard in Spanish startup transactions, implemented through a combined repurchase option (opción de compra) in the pacto de socios.

Option Pool and Employee Equity: Identification of any existing or planned employee stock option pool (plan de opciones — ESOP), its size as a percentage of fully diluted capital, and the tax treatment under Ley 28/2022 for qualifying plans in certificated empresas emergentes — including the €50,000 IRPF annual exemption for qualifying employee equity in startups and the deferred taxation rules under the amended Article 17.2.m of the Ley del IRPF.

Conditions Precedent and Closing: Conditions that must be satisfied before the investment closes — ENISA certification (if sought), satisfactory legal due diligence, execution of the updated pacto de socios, notarisation of the capital increase, and Registro Mercantil registration. A longstop date (fecha límite) for closing should be specified.

Representations, Warranties, and Indemnification: The startup's representations about its incorporation, ownership of IP (propiedad intelectual — Ley de Propiedad Intelectual, RDL 1/1996; Ley de Patentes, Ley 24/2015), absence of material litigation, employment compliance under the Estatuto de los Trabajadores (RDL 2/2015), and data protection compliance under RGPD (Reglamento UE 2016/679) and LOPDGDD (Ley Orgánica 3/2018). Standard indemnification provisions for breach of representations, consistent with Código Civil Articles 1101 and 1107.

Exit and IPO Rights: The investor's exit rights — drag-along, tag-along, put options (opciones de venta) at a minimum return multiple, and IPO registration rights. For certified empresas emergentes, the Startup Law's capital gains exemption under the amended IRPF rules may incentivise holding the investment for a minimum period before exit.
