Invite friends to unlock features and a free year of Air, recommend people, gift a plan and become an ambassador.
Bringing people to Aden opens features on the Free plan and can earn you a year of Air. You can also tell us about someone we should talk to, gift a plan to another team, or join the ambassador program. Your link and the people you invited are under **Account → Referrals**.
