The problem we see is that companies in their transition from physical office to a virtual and distributed workplace carried over all the meeting habits that are outdated.
We believe there is no longer need in standing meetings with fixed audiences.
With Meetter, you are basically setting your weekly meetings budget for the whole company and let topics compete for that time. This is a lot different from what is happening today: meetings fight for all the available time on everyone's calendar.
Meetter hours are not finalized until 15 minutes before the start. High priority, smaller and shorter topics win. Meetter makes all meetings about what they should be: about solving problems, not about socializing & sharing updates - there are less expensive ways to do that.
Can tool change the culture? We are optimists and believe they can.
Compare the difficulty of doing project task tracking in MS Word versus JIRA/Trello/Basecamp.
With meetings, we are still at MS Word stage and Meetter is a JIRA/Trello for meetings.
Unless you can find a tool to make these people understand the culture has a problem (also the hierarchy), I don't think any new tool can help.
Note: Basecamp, zoho and all others promise similar tools. You might want to change the intro video, maybe invest in voice-over with basic demo.
