I agree with the above statement. In the startup world, one person is doing at least 5 people's job. In my startup, I acted as COO, CTO, product manager, contract manager, team lead and more. If someone arrives 5 mins late to a meeting he/she is technically wasted 5 people's time. So that 5 mins wasted gets translated into 25 mins. This is why it is important to have delegation of authority and boundaries. I am now mentoring a startup of 7 students, its been 4 weeks since they came to a conclusion on their marketing campaign.

Committee gives you a perspective from different people. Which is valuable! Have the meetings if and only if you or them have to go outside the delegated authority to find a solution.
