The studio has operated under Czech company ID (IČO) 17064619 since 2024.** We build websites, web applications, and mobile apps for clients across the European Union.

We deliberately cap intake at 6–8 projects per month to maintain quality. We have served clients in 15+ industries — SaaS, e-commerce, healthcare, legal, hospitality, real estate, construction, education, creative agencies. Tagline: *"Web products that move you forward."* Trust signals: - 100+ projects delivered by the founder since 2016 (studio incorporated 2024, IČO 17064619) - 50+ returning clients - 95% on-time or early delivery - 30+ days of post-launch support included - Founded by a working developer who still ships code --- # Page: https://kosmoweb.cz/o-nas/ (About) Kosmoweb was founded in Prague by David Azarian, who has been building websites since 2016 - including years working at agencies where projects ran late, went over budget, or shipped half-finished. He formalized his practice as the Kosmoweb studio in 2024 (IČO 17064619). Kosmoweb exists to do the opposite: predictable prices, predictable timelines, one team that owns the work end-to-end. **Founder:** David Azarian — Founder & Lead Developer. Builds production websites and web applications, runs the agency. Speaks Czech, English, and Russian. LinkedIn: https://www.linkedin.com/in/dazarian **Approach:** - We quote fixed prices, not hourly. You know the cost before we start. - One team — designer, developer, project lead — handles your project. No agency hand-off chains. - We sometimes tell clients NOT to rebuild. If 3 specific fixes solve the problem, we don't propose a 120,000 CZK redesign. - Post-launch support is included for 30–90 days depending on project size. - We have rescued more than a dozen projects abandoned by previous agencies. **Industries served:** SaaS / tech startups, healthcare & medical, restaurants & food service, legal, real estate, hospitality, beauty & wellness, fitness, accounting, education, construction, e-commerce, creative agencies, veterinary, photography, automotive. **Business registration:** IČO 17064619, registered in the Czech Republic.
