We turned to Redwerk because we did not have the resources or the expertise in-house to build a cloud-based product. They're incredibly professional, responsive, and highly communicative. We launched the product last year, and we're still doing business with them. I'd recommend them in a heartbeat.

Redwerk serves as an extension of the developer team for Northeastern's central marketing team. They are able to build out entire sites, working within the existing WordPress framework developed in-house. This means they had to pivot as changes to that framework rolled out. Not only were they able to be flexible and iterative with their work, they also contributed improvements to the codebase that we could incorporate into the parent code and theme. Their QA work is meticulous and their communication is always responsive, smart, and clear.

What is so impressive about Redwerk, is their never say die to their commitment to their clients. During the terrible crisis in Kyiv, one of their programmers went to their office to do something that he felt was important. We never knew what happened here at Worldnow until months later. There is a noble and courageous quality to everyone that we’ve encountered at Redwerk. They do brilliant work and execute what they say they will always on budget and on time. I can’t imagine a greater company and group of people that we could’ve been blessed to work with over the years. I am very humbled by Redwerk.

Their team was quick and reliable, always communicating clearly when something was missing or needed more information. They molded their way of working around ours in order to facilitate production and communication even though we were not in the same time zone and they felt like they were part of the internal team. The team of developers we worked with was exceptional and listened to our every need. They took the time to let us know if they were seeing any issues on their end so that we can quickly take action on ours, which saved us a lot of time and money.
