What's Coming Up at the Builder Loft SF (June 24 – July 2)
Two packed weeks ahead at 525 Market. This stretch brings a pitch night with live VC judging, a agents hackathon, deep technical sessions on harness engineering and production agents, and the start of a stacked July lineup. Here's what's coming. Your weekly roundup of AI events, hackathons, and meetups at the AWS Builder Loft in San Francisco. Here's what's on deck.
This Week (June 24–30)
It's a big close to June from startup pitches to hands-on hacking to deeply technical meetups on how agents actually get built and shipped.
