Never walk into a cold room.
See which of your referral partners are going to an event before you go. Forward an invite, and your group sees it.
Forward it
Send any event invite to your personal address. No typing, no app to learn.
See who's going
Your group sees the event and taps "I'm going." You see who'll be in the room.
Walk in warm
Show up with allies, meet the right people, and follow up the next morning.
