Hi, I’m Stefan Isele, founder of ITIsele
After more than three decades in IT — from running my own company to leading large development teams — I now help businesses design, build, and evolve their software with clarity and confidence.
Our Story
ITIsele S.L. was founded by Stefan Isele, a German software professional living in Spain. With over 35 years in IT and experience across more than 60 companies, Stefan has seen the industry evolve — from early desktop systems to today’s AI-driven development. Before founding ITIsele, Stefan ran his own IT company with about 20 employees, later serving as Head of Development and Head of IT for organizations with over 60 developers. That journey shaped the mission behind ITIsele: combining deep experience with modern tools and AI to help businesses build software that truly lasts.
Mission & Vision
Empowering companies to deliver better software — faster, safer, and more maintainably — by combining decades of engineering experience with today’s AI and automation capabilities. Our vision is to grow ITIsele into a trusted software partner for companies in Spain and beyond — building a small, skilled team united by craftsmanship, curiosity, and reliability.
Philosophy
- Experience matters — real expertise saves time and avoids costly mistakes.
- AI is a tool, not a replacement — human understanding and technical craft remain essential.
- Clarity beats complexity — good software serves the business, not the other way around.
Looking Ahead
