Sectors with the Highest Growth Potential in Spain (2025–2030)

If you’re thinking about starting a business or diversifying, choosing the right sector can make the difference between a promising venture and an idea with little room to grow. At Adlanter, we analyse trends in the Spanish market with a strategic and realistic outlook. Below, we present the sectors that are already attracting the attention of both entrepreneurs and investors—and that show high growth potential over the next five years.

1. Health and Wellness

Demand for services related to physical, mental, and emotional health continues to rise. Population ageing, the increase in chronic diseases, and greater awareness of self-care are driving demand in areas like:

• Home care centres
• Accessible mental health services (apps, online consultations)
• Nutrition and healthy lifestyle businesses
• Medical technology and wearable devices

Why invest here: It’s a sector with sustained demand and room for innovation. The Spanish ecosystem brings together healthcare and tech talent, backed by research centres and specialised universities. There are also public funding programmes and institutional partnerships that lower entry barriers and accelerate growth.

2. Energy Transition and Sustainability

European policies, Next Generation funds, and social pressure are accelerating the shift toward more sustainable models. In Spain, this translates into opportunities such as:

• Solar panel installation and energy efficiency in housing
• Sustainable mobility services
• Environmental consulting for SMEs
• Recycling and circular economy projects

Why invest here: Growth isn’t a trend—it’s a structural need. One major advantage for companies that prioritise sustainability is the opportunity to deduct investments in renewable energy. The Spanish Personal Income Tax Law includes three deductions for energy efficiency improvement works in residential buildings.

3. Digitalisation of SMEs and Freelancers

While digitalisation is progressing, many small businesses are still far from reaching their tech potential. Solutions that help bridge that gap have a clear niche:

• Accessible management software
• Outsourced services for digital marketing and cybersecurity
• E-commerce platforms and no-code tools

Why invest here: Large market volume, clear need, and limited competition in certain niches. Government support for business digitalisation includes grants and specific programmes. For example, in 2021 the government launched the Digital Kit programme, allocating over €3 billion to support this technological transformation.

4. Education and Lifelong Learning

Education is no longer just a phase—it’s continuous. That opens the door to new business models:

• Specialised online learning platforms
• Digital academies focused on upskilling and reskilling
• Training for people over 50 and career transition programmes

Why invest here: Article 17 of Law 28/2022 promotes education programmes in entrepreneurship and digital skills. It also encourages collaboration between universities and companies and supports training initiatives in rural areas.
Education has become more flexible and the market more segmented, allowing for highly targeted and tailored proposals.

5. Services for the Elderly

Spain’s demographic pyramid is shifting, opening a largely untapped market:

• Personalised home care services
• Accessible tourism
• Assistive technology

Why invest here: Spain’s ageing population has a good income level and a clear demand for services that improve their wellbeing and independence. This market remains underdeveloped and holds great potential for innovation.

6. Applied Artificial Intelligence

AI isn’t the future—it’s already happening. But there’s still room to innovate in areas such as:

• Vertical applications for specific sectors (legaltech, agritech, proptech)
• Automation solutions for small businesses
• Consulting services for AI implementation

Why invest here: This is a sector that can scale fast at low cost when approached strategically. Additionally, Article 7 of Law 28/2022 on fostering the startup ecosystem offers tax benefits for tech startups. These companies will benefit from a reduced corporate tax rate of 15% during their early years and will be allowed to defer tax debt with no collateral or interest.

Conclusion: choose your sector with your head, not just your heart

Having a good idea matters. But having it in the right sector matters even more. The economic environment, regulation, and market demand are key success factors. Choosing a high-potential sector helps reduce risk from day one.
