Selected teams meet a mentor once a week for three months. The meetings are arranged around three subjects, one to a month:

• Product: what we are building, and for whom.
• Sales: where the first ten customers come from.
• Investment: what pays for the next twelve months.

The network is made up of founders, product leads and investment analysts. All of them volunteer, and each takes only one team a season — which is the only way meetings survive contact with a calendar.
