Our Mission is to shape the Future of your Inbox.

Email is the number one communication tool at work, but very little has been done to improve the design and functionalities it offers. At Gmelius, we research, develop and release products that transform your inbox into an advanced communication platform.

Payam is the main voice behind our customer service. An IT management student with a strong customer service and IT experience, he aims to help and solve problems while always keeping users' satisfaction in mind. He is mostly known for sharing his good mood and addictions to pop-figurines and coffee around the office. If he is not answering queries, you will probably hear his laugh burst out somewhere close by.
