The Story Behind XelveTec
In 2014, Kubilay Demirci founded XelveTec with a simple mission: help small businesses build professional websites without breaking the bank. What started as a freelance operation in Kreuzlingen, Switzerland has grown into a trusted agency serving hundreds of clients across Europe.
With over 10 years of experience, we've seen the internet evolve. We've watched small businesses struggle with slow websites, confusing designs, and poor SEO rankings. That's why we've made it our mission to deliver websites that are fast, beautiful, and optimized for conversions.
Today, XelveTec specializes in web design for KMU (small and medium enterprises) using the latest technologies: Next.js, React, TypeScript, Supabase, Stripe integration, and AI-powered personalization. Every website we build is designed to rank on Google and convert visitors into customers.
Our Values

No jargon. No confusing tech-speak. We explain everything clearly so you understand your website and how it works.
Performance First
Slow websites kill conversions. Every XelveTec website is optimized for speed, Core Web Vitals, and user experience.
