What Makes ThatByThem So Different?

Most developers you've worked with are generalists. They use many different technologies like Wordpress, Magento, and SilverStripe.

ThatByThem is very different. We are a SilverStripe-specialist agency. But what does that really mean?

As a specialist Agency:

  • We focus exclusively on SilverStripe development and helping clients overcome SilverStripe challenges.
  • We will help you overcome any SilverStripe challenge, regardless how complex the work might be.
  • We are the only agency that will give you a money back guarantee if we cannot technically complete your SilverStripe work.
  • We bring years of experience with us, 8+ years of working day and night on very challenging SilverStripe projects.
  • The two co-owners work directly with you, the guys who have the 8+ years experience! You are not handed off to some junior developer, account manager or a third-party and become a number in a long list of clients.

Our Back Story

In 2009 ,Dave partnered with Anh Le to build a SilverStripe web application called Cardplug. Cardplug did not make them the millions they had hoped for! So in 2010 they started ThatBythem, which was then called SilverBusters.

When you do the same thing everyday for so long, you naturally end up as experts on what you do. After 8+ years, we are still helping businesses take control of their SilverStripe, sites, apps and projects.

Dave Hennessy

Dave is a developer with 10+ years of hands-on coding experience. He has extensive experience working with 2 of the most popular stacks: PHP/MySQL (over 10 years of experience) and (8 years of experience working with the SilverStripe platform).

Anh Le Duc

Anh Le is a full stack developer with 8+ years of experience in PHP, MySQL, HTML, CSS, JavaScript, and JQuery. He is really passionate about the SilverStripe framework since 2009.
