Top things to do in San Francisco, week of March 30

A handpicked roundup of the best events in San Francisco for the week of March 30: AI demos, a Mission warehouse party, two underrated talks, and one outdoor thing that does not involve a marathon.

Sam CarterSam Carter·29 March 2026·2 min read·San Francisco

Short week, decent slate. SF in late March is the moment the calendar wakes up — Y Combinator demo prep is in the air, the AI scene is back from spring breaks, and Dolores Park is finally usable on a Saturday. Here are the seven things I'd actually show up to.

If you only want one filter, the SF this-week feed is the version of this list that updates daily.

Monday — AI Tinkerers Demo Night, SoMa

Five demos, eight minutes each, free RSVP. The most consistent signal-to-noise in the city. Goes hard around the YC batch transition, which is right now. Show up by 6:15 or you stand by the pizza.

Tuesday — Latent Space drinks, Mission

Biweekly informal drinks tied to the podcast. No agenda, mostly engineers, the kind of room where someone casually mentions an eval result that would be a tweet thread anywhere else. Free. Rotates between Sightglass and a Folsom spot.

Wednesday — "What we got wrong about RAG" talk, Hayes Valley

Hosted at a small office in Hayes Valley, real engineers, no recruiter slides. The talk is alot more honest than the conference version of it would be. Followed by drinks across the street. Limited RSVP, check the link the day before.

Thursday — Cerebral Valley unofficial drinks

The self-organising one. People drift to Verve and Souvenir Coffee in Hayes Valley around 6pm. No host, no list. The vibe is high through April because the spring fundraising cycle is loud right now.

Friday — Public Works basement, Mission

Underrated club night, deep house lineup that is not on most tourist lists. Doors at 10. Bring earplugs. Cash for the coat check, they hate the card reader.

Saturday — Presidio trail run + brunch, Crissy Field

Not a race. A casual 5k that meets at the warming hut at 9, runs the Battery to Bluffs trail, ends at brunch. Friendly to all paces. Genuine alternative to whatever marathon thing your group chat is pushing.

Sunday — "Founders Read Fiction" book club, Bernal Heights

Yes that is the actual name. Yes the joke is intentional. They actually read the book. Started by an ex-Stripe PM, meets monthly in a backyard. Honestly the most interesting room of the week most months.

What I'm skipping

The big sponsored AI summit at the Marriott. Ticket price is sus given the speaker list, and the after-party is recruiter-heavy. The lineup at the smaller venues is much stronger this week.

If you want this curated weekly without me having to write a post, Rifio's weekly digest for SF covers the same ground.

    Tinkerers fills up so fast now. Tuesday morning RSVP or bust.

  • Devon K.·29 Mar 2026

    Public Works basement is criminally underrated. Best room in the city for actual heads.

  • Ari T.·29 Mar 2026

    The Founders Read Fiction thing is real and weirdly the best networking I did all of last year.

  • Jordan P.·30 Mar 2026

    Wednesday RAG talk got moved to a bigger room btw, capacity doubled.

  • Sasha L.·30 Mar 2026

    Found three of these via rifio search this morning. Saved me an hour of luma scrolling.

  • Ben H.·30 Mar 2026

    Skip the Marriott summit, agree. Same six speakers as January.

  • Priya N.·30 Mar 2026

    Crissy Field run is a hidden gem. They have decent bagels at the end too.

  • Theo M.·31 Mar 2026

    Latent Space drinks Tuesday — confirmed Sightglass not Folsom this week.

  • Cameron J.·31 Mar 2026

    Cerebral Valley drinks Thursday is becoming way too crowded honestly. Fine for two months ago.

  • Lina W.·1 Apr 2026

    No raves on Saturday? Slow week.

  • Ravi S.·1 Apr 2026

    The book club one made me laugh. Going.
