The Pier is an 8-bit San Francisco where every attendee, speaker and volunteer walks around as a pixel version of themselves. Your ticket is the character slot, so the game starts the moment you buy it and runs until we meet at SFJAZZ in November.

Keynote
What you will actually hear
Every speaker here was hand-picked. We screened GitHub for people actively building in Ruby open source and went after them, which is how a talk about the Ruby stack that flies satellites ended up on the schedule.
Agentic Rails, already in production
Four talks from people who have shipped it, on the question that decides what your job looks like for the next few years.
-
Ryan Sherlock · Fin (ex Intercom)
Scales the AI customer service agent that grew out of Intercom: 150,000 HTTPS requests per second at peak, out of a Rails monolith.
-
CJ Avilla · Anthropic
On making an agent a first-class teammate inside your SaaS, rather than a chat box bolted to the side of it.
-
Madison Sites · Order.co
Wrangles legacy Rails for a living, and has the honest answer on what agents can and cannot fix in an old codebase.
-

The people who wrote your Gemfile
A conference pays for itself when the author of the thing that is currently breaking is standing ten feet away. Three independent answers to the job-queue question will be in the same room, all willing to argue about it.

More than a room of talks
Startups and scaleups get two tracks, and the tracks weave: when one is on stage, the other room is in an organized networking session, then they swap. Who you meet is on the schedule, so it never comes down 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.

Each room has a host keeping the mic moving through 70 to 100 introductions, so every 60 seconds lands.
59 open Ruby and Rails roles from 41 companies are on our jobs board today, GitHub, Chime, Gusto, Persona and AngelList among them. In November those hiring managers are sitting in your networking group, and you get the mic.
