      Kanda proved to be an exceptional choice for our development needs. They were much more [of] a partner to our startup than a vendor. The entire team treated our project like it was their own company, and the results showed that. Our customers were extremely please[d] with the desktop and mobile applications. I would definitely recommend hiring Kanda for any and all of your development needs. (Verified via email)

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.
