      ABSO came to our church’s school and remained flexible to deal with unexpected issues and set up several pieces of technology for us. They even came out afterwards when we were having some additional issues due to third-party equipment interfacing with what they set up. We are grateful for their attentive care for our campus to go above and beyond!

      John's ACT program is the complete plan for a business owner to Identify their ideal client, create their marketing message, build out their landing pages and then attract the traffic that is dying to buy their product. The customer desires the product because the message is so on target, so no selling involved! What could be BETTER than that!

      They were able to troubleshoot the issue to the best of his ability, verify the company warranty policy and checked with me to set up a time that worked to coordinate a call with the manufacturer. He then only brought me into the call when I needed to be, saving me time and frustration. Overall, it was a super pleasant interaction with IT and we were able to get the computer fixed. They other times I've had to reach out they have been helpful as well.

      I've needed IT help a few times over the last few months, and the SugarShot team had all the answers and made quick work of resolving my issues each time — even with my bumbling, not-tech-savvy explanations. It's so nice to have a vendor that I feel confident and comfortable reaching out to for assistance. They're knowledgable and nice — real people doing great work. 10/10!

DesignRush sustains a directory of over 40,000 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.
