We're continuing to see #AI companies lease office space in #SanFrancisco in high demand... below is just a sliver of those planting roots in the city. DM me if interested seeing our full report #AreaAI

We don't manually test features anymore. You can now run continuous QA features in Claude using “Feature Review” by Ranger. Feature Review is an always-on AI QA that runs in the background, fixing features while providing you and your team with full visibility. Never ask Claude to fix errors again.

For a decade, techbio optimized the drug discovery "paper mill": more molecules, faster. But the hard part - knowing which ones will work safely in humans - hardly moved at all. Late last year, I spent time with Axiom Bio, a company built around the idea that the real bottleneck is predicting clinical activity in molecules, *not* merely discovering them.

~$80B in VC funding to San Francisco-based companies Q1-Q3 2025 👀… many early stage companies growing and leasing office space in the city

Happy to see San Francisco on the list of safest cities, 1 of only 2 US cities to make this list. travelandleisure.com/safest-city-in…

With more and more employees going into the office, BART ridership is up 8.4% YOY. 2/3 of that growth can be attributed to riders entering/exiting BART stations in downtown San Francisco #ReturnToOffice

SF is filling up like a gold rush town right now Rental market is so insane that my cofounder has been homeless for almost 3 months Offices moving from Hayes hackerhouses to "The Arena" in the Mission to FiDi high rises, as headcounts increase

Top 3 U.S. Talent Hubs 2025: NY, SF, LA While it was a race to find engineers in more affordable locations, we're now seeing the shift to quality / highly productive staff in knowledge centers like NY, SF, LA. Most of them working together in the office rather than remote. This shift means the gateway markets are growing and the secondary markets are slowing.

Interesting trend we're seeing... ▶️ Pre-pandemic: "view space" rents moved parallel to "non-view space" rents ▶️ Post-pandemic: "view space" avg rent INCREASE of $5.30/sf; "non-view space" avg rent DECREASE of $4.40/sf

Congrats on the new office! Big things ahead for Browserbase 🚀@pk_iv @browserbase @erin_goode @JohnRoskos2 linkedin.com/posts/john-ros…

Office market is tightening… New construction is limited, and we’re seeing availabilities decline across the board. Quality built out space is leasing quick (especially when furnished)

In-office requirements have increased ~26% YOY for Fortune 100 companies... Avg # Days in Office per week: - July 2024: 3.1 - July 2025: 3.9 With office inventory declining in most markets, supply constraints will become more acute in the coming years.

The # of active leases for AI companies in the Bay Area has increased exponentially since 2020... - 2020: 13 active leases - 2025: 325 and counting ...we don't see this slowing down any time soon 🚀

Seeing more and more institutional investors focusing on SF office... 💥🔁 bizjournals.com/sanfrancisco/n…
