Dave & Anh Le

We’re a company of two because that is the only way to guarantee outstanding results. In other words, we complete all your SilverStripe work with our  bare hands. You communicate directly with us every day. No account managers, no average developers, no language or cultural barriers. Simply two SilverStripe specialists – motivated to listen and serve, from start to finish.


Anh Le

Originally from  Vietnam, I now co-run ThatByThem in the Philippines. I am a full stack developer with 8+ years of experience in PHP, MySQL, HTML, CSS, JavaScript and JQuery. I'm very passionate about the SilverStripe framework. Keeping the agency small allows me to do what I love every day: working directly with clients, not managing staff.

I'm a developer with 10+ years of hands-on coding experience. I have 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). When I am not working, I'm enjoying the sunny days in the Philippines.

PSD To SilverStripe

Your PSD design, sliced and hand coded into a high-quality, fully functional SilverStripe site. You get a SilverStripe theme that works flawlessly across all popular browsers and devices, keeping both users and search engines happy. Once we're done slicing, coding and cross-browser testing your theme, we upload it to a staging server where you can take it for a test drive. Next, you share your comments and feedback, and we will do all the necessary tweaking before handing you over the completed site. We will work tirelessly with you to ensure you are 100% happy with the conversion.

Web Design

Everyone wants a beautiful website that works on mobiles, tablets, and desktops. And we have taken that requirement one step further. The SilverStripe sites we build for you use themestripe, our block builder functionality as its foundation. This allows you to have more control over how and what you would like to appear on your website. You can add call-to-actions, sections, and move around blocks on your website to improve your performance. You won’t be locked to a single design or layout. As your business grows, you can make changes to your site to reflect that growth. Our sites grow with you over time.


We do more than just deliver websites. Aside from providing you with top-notch sites, we will also help you become more knowledgeable on SilverStripe. We use Remote Desktop Training to teach you how to master this content system. It usually takes an hour or two to turn you into a more SilverStripe savvy individual. We will share your PC screen and guide you on how to make changes and how to become a competent administrator of your website.  This is a fantastic way of learning how to take more control over your website and reduce the cost of maintenance, updating, and administration.


Experienced SilverStripe developers charge premium rates that range anywhere from $40 to $150 per hour. Since our little agency operates offshore, our operating costs are lower.

In 2008, we took on our first client, Ofer Akerman, giving birth to SilverBusters, the predecessor of ThatByThem. We have been helping clients ever since, and we are proud to have Ofer as our client still.

It’s straightforward and safe. We take a copy of your existing SilverStripe website and set up a staging version of your site. All development work will be completed on this version of your website. Once you are happy with our work, then we push those changes to the live version of your site.

Given that we are a small agency, so we need to turn over projects promptly and efficiently. This means we prefer to work with clients who can communicate promptly.

We are very comfortable with both front-end and back-end development.  Clients hire us for our attention to detail. You can hire us and hand over the project to your client when its completed, without wondering is the project responsive and semantic.

We do offer monthly maintenance packages for regular clients who want to aggressively grow their online presence.

We sure can. We love this type of project. We usually use ThemeStripe, our SilverStripe site-builder theme as a foundation to build your new website. This helps reduce the overall cost of the redesign.

The majority of the agencies we work for are located in Australia and New Zealand. But our clients and work span the globe.
