Keynote

Day 1–3

More than a room of talks

Half the value of a conference is who you meet, so it is on the schedule rather than left to the coffee queue.

01
Everyone gets a mic

You are matched into at least two networking groups of 70 to 100 people. In each one you get 60 seconds on the mic to say who you are and what you are building.
02
Teams of 5+ get a longer slot

Bring five or more from your company and you get extended time, and slides, to introduce the team to the room.
03
Founders' round with Garry Tan

A dedicated group for founders and founding teams with the President and CEO of Y Combinator.

Bring your team Ask for an invoice

Season open

The conference starts now

Your ticket is a character slot. The game begins the day you register, months before the doors open.

01
Your character joins the map

Upload a photo and get your Cloud Card: an 8-bit version of you, up on the clouds on one big shared picture with everyone else who is going.
02
Tasks and games, starting now

Quests run in the conference app and the SF Ruby Slack from the day you register until November. Complete them and badges stack up on your Cloud Card.
03
Arrive knowing your crew

We match you into a group by shared interests. Find your people online first, then in person at SFJAZZ, where the last badges are earned face to face.
