At the moment, it is not possible to merge company profiles.
However, we already have a feature request for it on our Feedback page. You and your colleagues can go there and vote for this feature! 😊
This page is reviewed weekly by our Product Managers and we build our roadmap based on your feedback. We consider upvotes and comments for all decisions, so if you like someone else's idea, be sure to give them a thumbs-up as well!
