Butter

MeetButter is an all-in-one video conferencing tool for workshops, interactive meetings, and live courses. It gives tools for meeting and workshop hosts to
1) Prepare the meeting up front - no more setting up things on the fly
2) Run the workshop with a set of tools such as breakout rooms, polls, and timed agendas - no need for extra tools, and
3) Send out structured takeaways after the workshop

For complex meetings with 8 to 50 participants. E.g. workshops, training sessions, online courses
