Employees at Mailchimp, an email marketing company with about 100 employees, decide on new features and services in a similar way. If someone has an idea, they attempt to recruit another person to help them work on a prototype or to help convince others. At Mailchimp, people get excited by good ideas, and they are trusted, so they have the autonomy to follow their instincts. To be recruited, a person must consider it more interesting or useful than the things they are already working on. Like the ants, recruitment turns to escalating commitment over time as more people are recruited to the project. When enough people are recruited, a team is formed and commits to seeing the project through to completion. In this way, ideas compete for resources and the best ideas end up bearing fruit.
