Gmelius is a tool that aims to bring together productivity, collaboration, and automation tools into one workspace within Gmail, allowing teams to collaborate, communicate, and automate tasks without adding another siloed tool. Founded in 2016 by Florian Bersier, Gmelius was born out of the need for better collaboration tools that could support changing work needs beyond email. Today, it has over 10,000 paid customers, including startups and enterprises like Netflix, and offers features such as collision detection to avoid double replies and automation through integration with Zapier.
