We at commercetools coined the term ‘MACH’ in 2018 to describe the e-commerce architecture we developed that helps companies be more agile, more flexible and move faster. However, we were not the only ones using MACH. In June 2020, commercetools helped found the MACH Alliance, a non-profit co-operation to introduce a new, open and best-of-breed enterprise technology ecosystem. The MACH Alliance is the collective voice of a new generation of vendors offering MACH-compliant products and services. Members of the Alliance have all passed a rigorous test that certifies their adherence to MACH principles. The MACH Alliance aims to show how businesses can benefit from open tech ecosystems that are microservices-based, API-first, cloud-native SaaS and headless in our complex modern technology landscape.
