Build things.
What this is
This Sunday, eight people, from vibe coders to 20-year-hardened developers, will show how they're building. Some of it is the kind of thing everyone can follow. Some of it is deep and technical, the "what the heck" kind. And a lot of it sits in between.
Sharathons are for everyone. We share how we're building, how we're thinking, and the resources we use.
Each one gets seven minutes to show how they build, then two minutes for questions. After the demos we hang out, turn laptops around, and look at what everyone else is working on.
Want a stage slot? You can still apply through Friday, November 13 at 8:00 PM PT. When you RSVP, tell us in a sentence or two what you want to show.
Where we've been
The first Sharathon was in Ocean Beach in May. The second brought us to Brew in August, with 22 participants and 13 live demos.
San Diego AI Studio Sharathon: 13 demos, one room:
A few of the things people showed last time:
Silt (https://silt.run): infrastructure for real-time browser multiplayer. A QR code went up, and people joined on their phones mid-demo.
Heurchain (https://heurchain.com): memory that follows you across AI vendors, so the work you already paid for isn't locked in someone else's product.
GliderSim (https://5drealities.com/games/GliderSim.aspx): a VR paragliding simulator that ships on two stores, with Google Earth loaded in so you can fly anywhere.
The short version of all thirteen is at sandiegoaistudio.com/sharathon/2 (https://sandiegoaistudio.com/sharathon/2).
"It's not that the capability is not there. It's that you just haven't found a way to string it together of what's available. Like I just didn't give good enough instructions in the agents MD file or whatever it may be. I don't have a nice enough memory tool that I put in there or something like that. So it all kind of feels like skill issue when it doesn't work."

🤖 Hardware and robotics folks
🌊 Nerds looking to hang out, find collaborators, or meet people
Thanks to Lovable
Lovable is sponsoring Sharathon 3 with 100 Lovable credits for every builder who comes. We'll hand out the credit code at the event, so you can keep building after Sunday.
🎤 Four ways to take part
Demo slots. We'll host eight demos on stage, nine minutes each: seven to present, two for questions. Stage slots go to setups that fit the theme: long-running agents, software factories, AI operating systems, second brains, and harnesses/interfaces. You can still apply through Friday, November 13 at 8:00 PM PT. When you RSVP, tell us in a sentence or two what you want to show. We'll line up a couple of standbys in case a slot opens.
Show your table. Turn your laptop around for the people sitting near you. No stage needed, and anything goes: on theme or not, finished or half-baked.
Bring a schematic. A diagram, a workflow, or an idea you're trying to work out. Nothing has to be production level.
Just watch. Being a fly on the wall is a totally legit option. Laptops are optional, and you never have to explain anything you'd rather keep private.
Bring a laptop if you want to show something, bring one question about how a system works, and feel free to bring friends. The venue has a projector, sound, a mic, and USB and HDMI adapters.
☕ The spot
Brew Coffee Spot is a super rad coffee shop in La Mesa, near Lake Murray. They close early, so we get the whole place to ourselves.
Pizza is on us. There's a free parking lot out front, and Brew's coffee and drinks are available to buy.
We (Lucas and Bree) will try to greet everyone, but if we miss you, come say hi. Look for Lucas: big friendly dude, dark beard, short curly hair.
📅 The flow
4:30 PM: Doors open. Come in, chill, and meet people. Tables are open for show and tell from the start.
5:30 PM: Quick welcome, then stage show-and-tell, round one. Four demos, seven minutes each plus two for questions.
Around 6:15 PM: Break. Mingle and hit up the presenters with any questions.
Around 6:35 PM: Round two. Four more demos on stage.
Around 7:15 PM: Quick-fire. Anyone can take the mic for 15 seconds: an intro, an ask, or an announcement. Sign up at the door.
Around 7:25 PM: Open floor. Show your table, pair up, wander, or look over shoulders.
8:30 PM: Wrap.
🎟 Spots
Spots are limited. If it's full, join the waitlist, and we'll let people in if any open.
🎙 Photos
Nothing is live-streamed. If someone is shooting photos or short clips, you can opt out at the door. We'll post a full demo only with that presenter's permission.
🧰 Explore before you come
Browse the Studio's Harness Ledger (https://sandiegoaistudio.com/projects#ledger) to see how people document their AI systems and try the optional self-audit. No score or completed audit is required to attend or apply for a demo.
The Sharathon recap and resource collection (https://sandiegoaistudio.com/share) has material from the earlier events.
More from the Studio is on YouTube (SanDiegoAIStudio).
