Rogers Communications, and Express each had one goal: to transform their monolithic commerce platform into something far more modern. To fulfill that mission, all of these major brands chose commercetools. So, we asked technology leaders who previously worked at these businesses – and now work at global digital agency Valtech – about their experience with a commercetools migration to give you an inside look on what working with commercetools is really like, from beginning to completion.

Valtech VPs on why commercetools was the right move

We spoke to Warren Cable, Vice President, Commerce at Valtech (formerly of Rogers Communications); Mihaela Mazzenga, Senior Vice President of Technology Strategy (formerly of; and Tim Steele, Vice President, Commerce (formerly of Express) to get all of their insights about what a migration from a rigid monolithic platform to commercetools actually entails and all the benefits that come with it. Here’s what they said.

How did your journey lead you to commercetools? What was the initial reason commercetools was chosen for your project and why was it the best choice? 

Warren Cable:  We wanted to future-proof our tech stack with technology focused on business outcomes.  We made the decision to move away from our monolithic commerce platform and started with the CMS, deciding to go the headless route. This was around 2018 when the idea of headless was not as widely adopted as it is today.

We chose Berlin-based startup Contentful for the CMS. They introduced us to commercetools, who were, at the time, also an up-and-coming startup. We got to know the team over in Berlin quite well. We loved the product and the company's vision of disrupting the enterprise eCommerce industry.

Mihaela Mazzenga: I was very familiar with SaaS offerings and the concept of decoupling your core business logic away from your presentation layer, so I sought out the best vendors in the commerce space. commercetools was chosen for their expertise and for their scalability in core commerce capabilities.

Tim Steele: I learned about commercetools when we started looking at new commerce platforms to replace ATG, our existing commerce platform. We were looking at commerce platforms that could natively support multi-channel interfaces through APIs. As we looked at commercetools, its headless and API-first approach was perfect for our use case. Furthermore, commercetools being a scalable SaaS solution matched our strategy to move our existing eCommerce to the cloud for better scalability and resiliency benefits.

Can you describe what your partnership with commercetools was like? How was it working with the commercetools team during your project? 

Mihaela Mazzenga: We were on a very tight timeline, so we leaned on commercetools a lot for their expertise and collaboration, both through their solution engineers and standard support. commercetools acted in true partnership to support us.

Tim Steele: During the entirety of the ATG re-platform project, we worked very closely with the commercetools team. They were onsite for the kick-off and developer training, and continued to support us through our go-live. Our team had weekly touch bases with commercetools services and the success team. We collaborated and confirmed architectural and technical design decisions that helped us best leverage the platform. They helped guide us, so we had the best solutions and assisted with technical, operational and cultural changes involved with a composable commerce migration. Throughout the roll-out and deployment of the commercetools platform, they helped with performance testing and debugging. The commercetools team was very invested in the success of our project.

Is the project you were working on now live? At a higher level, what changes did you see before and after implementation across your organization? 

Warren Cable: We saw a significant shift in our team culture. Going to market with best-of-breed tools, with brands that are challenging the traditional ways of going to market – that can have a positive impact on your team culture and attracts a certain kind of engineering talent that really does make a difference to your business. 

Mihaela Mazzenga: Yes, the project is live. In terms of operations, all of the active server management we were doing daily went away and we no longer had to worry about scaling for peak traffic.

Tim Steele: The project went live and was a success through a peak holiday season. After the go-live, there were several technical, operational and cultural changes. Technically, we have found integration with third parties to be faster and easier. Operationally, we could focus less on platform updates and maintenance and, instead, on new features and improvements. Culturally, our development practices shifted to decoupled and iterative deployments instead of large monolithic changes. Overall, we found that migrating to commercetools allowed us to deliver value faster and operate more flexibly than our previous platform.
