Fractional CTO in Barcelona

Expert technical leadership for Barcelona startups. CTO services in CET/CEST timezone. Build, scale, and transform your product without full-time CTO costs.

Why Barcelona Startups Choose Fractional CTO

Barcelona is a fast-growing tech hub in Southern Europe. The city is home to Mobile World Congress and attracts international talent thanks to quality of life, lower costs compared to other European capitals, and a developed startup ecosystem. Industries like Travel Tech, Mobile, Gaming, E-commerce, and HealthTech thrive here.

However, Barcelona's ecosystem creates unique challenges: competition for technical talent is growing, Spanish labor law can be complex, and startups must comply with GDPR requirements. Many startups find that traditional full-time CTO hiring — costing €100K-€180K+ plus equity — is impractical at early stages.
