      Catherine Cornell's Review Sourced from Google

      This place was great for many years but is apparently out of business although I can’t be sure. I am an existing customer and just got a new bill even though I just paid my bill. I have called and emailed many times - no response. Not sure what’s going on. Stay away.

      Sue Schroeder's Review Sourced from Google

      101 digital seems to have just shut down services, with no notice to it's clients. They don't answer the phone, and emails auto answer with a message to contact Anita at Sunny Direct, who also doesn't return phone messages or emails. They've left us in a very difficult position just as we head into our busiest time of the year. If they come back in any form, I'd suggest buyer beware!

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.
