      Denise !'s Review Sourced from Google

      I can only recommend Lindner IT to everyone.Robin Lindner always takes care of our various IT projects quickly and comprehensively. And if we ever had problems, he was usually able to fix them after a short time.Working together is fun and we don't regret our IT switch to Lindner IT in any way. On the contrary, we should have done this much earlier.Big thank you for the great support!

Sources

DesignRush sustains a directory of over 30,000 agencies categorized by service category, location, expertise, and reviews. We build our database in two ways:

  • Our dedicated team of agency experts actively searches the web for top-performing companies. We then pull information from their websites, online presence, and client testimonials to verify their status and qualifications prior to listing.
  • The agencies listed get notified of their profiles on the website and they can choose to claim it or not, which suggests their availability for more collaborations.

Agencies can also reach out to DesignRush and must go through the verification process prior to being listed.
