SD Investors · San Diego, La Jolla & North County
The room where the county builds.
An invite-only room of San Diego’s founders, operators, and investors deciding what AI does for their businesses, and for the city they’re building it in. Off the record, capped, and local to its bones.

Four things you can’t get anywhere else in San Diego.
Every room, one calendar
We track every business, tech, and investor event across San Diego (Sorrento Valley, La Jolla, downtown, and up through Carlsbad and North County), refreshed daily, so you never hear about the good one after it happened.
The weekly briefing
One email: what’s worth your time this week, who’s gathering where, and what San Diego builders are actually doing with AI. Curated by people who go, never scraped-and-dumped.
A listing that means something
The member directory is vouched-for, not paid-for: the short list people check before they hire, fund, or partner in San Diego. Founding members hold their numbers permanently.
Private tables + introductions
Our own gatherings are members-only, off the record, and small on purpose: real numbers, real decisions, and the introduction you actually needed.
Since the Spirit of St. Louis
San Diego has always been built by people who make things happen.
In 1927, Ryan Airlines built the Spirit of St. Louis on the San Diego waterfront in sixty days flat, an impossible spec, an impossible deadline, delivered anyway; the airport has carried Lindbergh’s name ever since. Three decades later the city voted to hand its most valuable ground, the mesa above Torrey Pines, to UC San Diego and Jonas Salk, a beach town betting its best land on research instead of real estate. Everything from Scripps to Illumina compounds from that ballot. SD Investors is where the people doing that now find each other.
This week around San Diego
The best local events to grow, or unwind.
The calendar refreshes daily from every chamber, tech council, and founder gathering across San Diego. Members get the full slate in the weekly briefing.
Community events belong to their hosts, we just make sure you know. Sources: Startup San Diego, AI Tinkerers San Diego, Backland Labs, San Diego Machine Learning, the San Diego AI Developers Group, Biocom California, the San Diego Regional Chamber, and Connect w/ San Diego Venture Group, plus the Carlsbad and Oceanside chambers. Refreshed daily. Members get the full calendar weekly. Comedy is graded before it is listed: top-reviewed clubs, a named comedian on the bill, three a month, no open mics.

🐾 The nonprofit initiative behind this network
Every room we open is in direct partnership with Best‑Friend.org
Millions of healthy animals are put down simply because shelters run out of room. Best‑Friend.org is the world’s first decentralized nonprofit with a planned ending: it builds the system any community can install to solve shelter overcapacity, then disappears because it is no longer needed. It doesn’t ask anyone for money. Sharing is the donation.
That is what this network is ultimately for. The rooms build the businesses; the attention they earn goes to emptying the shelters.
