Instant Agenda facilitates "lean coffee" style meetings. Participants vote on topics, and then IA runs through the agenda for you and prompts you to move on when time runs out on a topic.
Biggest value for me isn't the facilitation of meetings in real time, but the collaborative agenda building. Have a weekly 1:1 with your boss? Use IA to add topics throughout the week, and review a few minutes ahead of time so you know what you'll be talking about.
Instant Agenda is the best (I use for all of my standing meetings) because it keeps the team on track and doesn't put me in the position to be the bad guy when someone derails my meeting or goes down a rat hole. It has a feature where the group can vote if something is going off topic which I love. I wish all of my customers and partners used Instant Agenda.
The responsiveness of the team is a big plus for me. If I have any questions or suggestions the team gets right back to me. Additionally, I've seen some of my suggestions implemented in the product.
