This doesn't look good. Other than medium account, they can always publish what's going on with other social media channels even on this thread alone. They said that they are working on their product. Maybe believe that they can keep the word about it? But they should be posting snippets of progress to keep their investors and followers not worried about what's going on.
Medium Leadrex has been deleted, there is writing Error 410, I don't know why, I checked on their social media especially on the last Twitter they updated was in August then what about now?
