SF Bay Area Events: July 20-26, 2026

The week at a glance

The strongest concentration is Tuesday through Thursday: a Microsoft agentic-AI demo night, AMD's two-day AI infrastructure conference, a climate hackathon, and three different ways to meet people building AI systems. Friday through Sunday shifts toward hands-on building, from the You.com agentic hackathon to AINative's three-day startup camp and a low-pressure Sunday code-and-coffee meetup.

All times below are Pacific. Registration status can change quickly, especially for approval-only events.

Tuesday, July 21

Foundry Live Demo Night

Category: AI demo night. Venue: GitHub, 88 Colin P Kelly Jr St, San Francisco, CA 94107. Host: Microsoft Foundry Live, hosted by Arte Merritt. Audience signal: The page describes the series as a monthly Microsoft showcase for startups building on Microsoft Foundry and shows 285 people going. 1

The evening is built around local Bay Area agentic-AI startups: doors and networking from 5:00 to 5:45 PM, introductions until 6:00, live demos from 6:00 to 7:00, then networking through 8:00. Registration is approval-only, so this is the best pick for readers who want to watch products being demonstrated rather than sit through a general panel. Register on Luma.

Cinder + Accel TrustCon Happy Hour

Category: Trust and safety tech-social. Time: 5:30-8:30 PM. Venue: Accel's San Francisco rooftop; the exact address is revealed after registration. Host: Cinder and Accel. Audience: Trust and safety platforms, operators, investors, and researchers. 12

TrustCon runs July 20-22 in San Francisco, and Cinder's participant guide positions this Tuesday evening gathering as its annual community happy hour during the conference. The event is private, space is limited, and approval is required. Request RSVP access.

Wednesday, July 22

AI Power Hour Climate Hackathon

Category: AI x climate hackathon. Time: 4:00-7:00 PM. Venue: 9Zero Climate Innovation Hub, 350 California St, 4th floor, San Francisco, CA 94104. Host: 9Zero and Guthrie Gintzler. 2

Bring a laptop, not a polished portfolio. The first hour covers AI tools, judging criteria, and climate problem prompts; the second is a one-hour build sprint with mentors; the final hour is for demos, prizes, and mingling. Solo builders and teams are welcome, and the page says no coding experience is required. 9Zero describes itself as a members-only community of founders, investors, scientists, and innovators, so check the registration terms before heading over. View ticket options.

AMD Advancing AI 2026

Category: AI infrastructure conference. Dates: July 22-23. Venue: Moscone West, San Francisco. Host: AMD. Audience: AI developers, enterprise customers, and technology partners. 3

This is the week's largest formal conference option. AMD says the two-day program combines workshops, breakout sessions, and practical material for teams building or deploying AI infrastructure. The official agenda highlights sessions on enterprise AI outcomes, network transport from clusters to AI factories, and what digital-native companies are building. Dr. Lisa Su appears in the posted Thursday agenda image; the page does not provide a complete speaker roster in the extracted details. Registration is open, with a warning that space is limited. See the official agenda and registration.

Ascent Valley AI & Tech Networking

Category: Founder and investor networking with pitches. Time: 7:00-10:00 PM. Venue: Rick & Roxy's, 2131 Lombard Street, San Francisco, CA 94123. Host: Ascent Valley. 4

The format is more structured than a bar mixer: the listing calls for investors, tech experts, founders, AI specialists, operators, and immigrant entrepreneurs, with selected founders giving five-minute presentations and receiving investor feedback. The page is marked open for registration; no ticket price was visible in the accessible details. Reserve a seat on Eventbrite.

Thursday, July 23

SF AI Tech Stack Hack Night

Category: Builder hack night. Time: 5:00-9:00 PM. Venue: Bright Data Web Data Loft, 625 2nd St, San Francisco, CA 94107. Host: Bright Data and Adam Chan. 5

The brief is unusually concrete: agents, data pipelines, retrieval, evals, observability, model APIs, orchestration, deployment, and developer tools. Expect a short framing session, open build time, practical experiments, lightweight demos, food, and drinks. Admission is free but approval-based because space is limited. The intended audience is engineers, founders, product builders, technical operators, and students who are actively experimenting with AI systems. Apply on Luma.

Tech Talk: The Software Factory Series

Category: Agentic software engineering talks. Time: 5:30-8:30 PM. Venue: Headway HQ, 535 Mission St, 9th Floor, San Francisco, CA 94105. Hosts: Denali McBriarty and Matthew Tse. 6

The inaugural Headway event brings together practitioners from Headway, OpenAI, Ramp, and Cursor. The listed speakers are Adam Kuhn, Richard Lee, Mike Luo, and Sunny Shah, discussing agentic systems, evaluation frameworks, and AI-powered development workflows. The page shows 46 going and four spots remaining, with approval required. Request a spot.

Tech Leaders Fine Dining Series: Wayfare Tavern Edition

Category: Founder and engineering-leader dinner. Time: 6:30-9:30 PM. Venue: Wayfare Tavern, 201 Pine St, San Francisco, CA 94111. Host: The Operator Collective, hosted by Brett Foreman. 7

This is the clearest invite-only option of the week. The event is set in Wayfare Tavern's private Juniper Dining Room for founders, CTOs, chief product officers, and VPs of Engineering. There are no panels or pitches; the host says seating and conversation topics are curated around the guest list, with AI, product, and engineering challenges as likely discussion areas. Dinner is covered, seats are very limited, and approval is required. Request an invitation.

Friday, July 24 through Sunday, July 26

You.com Agentic Hackathon

AINative StartUp Camp

Category: Startup camp and demo program. Dates: July 24-26. Venue: Wefunder, 1885 Mission St, San Francisco, CA 94103. Presented by: Wefunder x Fondo x AINative Studio. 9

The three-day format starts with idea pitches and team formation, moves into a build day with mentor office hours, and closes with demos to founders, operators, and investors followed by awards and feedback. The posted schedule gives doors at 6:00 PM, pitches at 7:00 PM, and team formation at 8:30 PM on the opening date; the later build and demo blocks are laid out on the event page. Registration is tied to an AINative account and a 30-day Pro trial offer. Register for the SF camp.

Y Combinator Startup School 2026

Category: Selective technical-builder conference. Dates: July 25-26. Venue: San Francisco; the official page does not publish a venue name. Organizer: Y Combinator. 10

This is the strongest quality signal on the weekend, but it is no longer actionable for new applicants: Y Combinator's official page says the event is no longer accepting registrations. The target audience is technical builders, including students, software and ML engineers, and people who can show strong technical work. The posted speaker list includes Jensen Huang, Sam Altman, Patrick Collison, Jeff Dean, Boris Cherny, Alexandr Wang, Chelsea Finn, and others. Check the official page for updates or future YC events.

SF AI Code and Coffee

Category: Informal AI developer meetup. Time: 2:00-5:00 PM on Sunday, July 26. Venue: Salesforce Park, central grassy area on Level 4, 425 Mission St, San Francisco, CA 94105. Hosts: John Komarnicki and Pat Santiago. 11

This is the low-friction Sunday option: an inclusive, informal coworking and networking session for AI developers, engineers, founders, investors, and enthusiasts. The organizers start with an introduction circle, then let the group self-organize around projects, job leads, or conversation. The page shows 74 going and asks attendees to register on Luma; the exact outdoor meeting area may move with the weather. Register for Code and Coffee.

How to choose

Want to see what teams are actually shipping? Start with Foundry Live on Tuesday or the You.com hackathon on Friday.
Want infrastructure depth? AMD Advancing AI is the most substantial conference; the Software Factory Series is the more compact evening alternative.
Want to build something in one sitting? The 9Zero climate sprint is beginner-friendly, while Bright Data's hack night assumes you are already experimenting with AI systems.
Want a high-signal room? The Wayfare Tavern dinner is the most selective; Cinder + Accel is the better fit for trust and safety professionals.
Want a lower-commitment Sunday? Code and Coffee is the most accessible option, with no pitch or formal agenda after the opening circle.
