We provide an intuitive simple-to-use solution for both data feed management and PPC which enables online retailers, brands, and agencies to sell and advertise globally. Today, 6000+ global customers continue to boost their business to the next level using Channable’s solution.

We are the market leader in Benelux and are now conquering the rest of the world, with teams for the US, DACH, Nordics, UK, Iberia, France, and Italy, based in our office in Utrecht.

How we develop software

We have a strong engineering culture with a focus on correctness, reliability, and maintainability of our code. We have a number of services written in Python and in Haskell. Each service exposes a REST API and our services are composed together in a service-oriented architecture in which we can continuously improve each service. Have you already read our tech blog?

We employ a continuous integration pipeline that allows us to quickly and safely deploy features, updates and fixes several times per day. Our infrastructure is running on Google Compute Engine and we strive to automate each part of the software development process as much as possible.

"There are a lot of technological challenges waiting for a solution when you are processing large amounts of data. Individual developers are given a lot of ownership around projects and innovation is very important. Together with your colleagues, you can have some deep technical discussions. Our open culture ensures there is an enjoyable ambiance during work. After work, we have groups doing sports or games together."

- Reinier, Haskell Software Engineer at Channable.
