The ICT Industry in Spain: Insights and Data
Spain is one of the most important ICT markets in Europe, in terms of volume. In 2025, the net worth of the entire sector was estimated at around $62.9 billion. This makes it an important national economy.
According to a report from ICEX, there are more than 34,000 ICT companies in Spain that engage 550k+ workers in this field.
Additionally, the digital economy contribution of Spain, which includes the ICT industry, contributed 26% of Spain’s GDP in 2024. Due to its geographical location and favorable IT climate, the industry evolves with big steps, and sometimes it appears that it overwhelms the infrastructure.
Why You Should Work With a Spanish Company
Spain is great for all types of IT professionals and companies - from digital nomads and startups, up to big corporations, you can find them all in Spain. The best part is that social education adds great value to digital business culture and develops the environment and industry, making it a great opportunity both for businesses and professionals.
Another reason why Spanish IT companies are a good option is the hourly rate and reliability. According to Payscale, the average hourly rate of a developer is around 25.43 Euros, which is below the European average. Also, the good business tradition will ensure you a sufficient and healthy experience with your projects.
What You Should Be Aware of When Working With Spanish IT Companies
Although it has experienced a huge growth in the sector, Spain has a shortage of qualified, experienced information technology (IT) professionals to meet the growing demand, especially in the major cities, which dominate the IT market in Spain. This means that, together with great project experience, there is a risk of average project execution, in spite of having higher expectations.
Are Spanish Companies Reliable?
In terms of reliability, Spain has never been the top leading country, but also not the last. Due to social culture, it is known that Spanish companies like to bargain and negotiate the prices & services. While some may find this frustrating, most of the businesses like this feature, as it’s one of the business fundamental practices.
How the Spanish IT Industry Relates to the Neighboring Countries
With all the IT industry growth Spain has registered in the last few years, the country competes with France, which has also managed to score impressive numbers in the IT sector. However, the markets are slightly different for both of them, including but not limited to linguistic differences. Probably, the cases of Spain and France are two extremely important cases where culture crosses the IT industry.
Overall, Spain has managed to keep the IT industry growing, even with the human resources challenges that it is facing. And it is expected in the coming years that the regional IT competition will lead to a surprise evolution and increased attractiveness to potential clients.
Most of the Spanish IT companies are already registered on TechBehemoths and can be found on their dedicated page. Feel free to contact any web agency, IT firm, or software company you consider that can help your project.
