The real reason founders move to SF isn’t the capital.
It’s the hallway conversations.
So we built a hallway.
Launching @superherohotel: 6 floors in a historic 1920 Nob Hill building.
10-min walk from @frontiertower.
Members have raised $150M.
Events have pulled 70K.
Sleep at the hotel. Build at the Tower.
Come for 4 weeks. Ship, raise, break through 👇
Great to host @christine_tsai of @500GlobalVC last week.
500 Global backs globally ambitious founders building fast-growing tech companies. We bring the best repeat global founders to SF with @frontierheroes.
Same mission, different angles. Can’t wait to partner up and learn from each other.
$150M+. That’s what founders in the Frontier Tower ecosystem have collectively raised in VC for AI, bio, neurotech, robotics and crypto in less than 1.5 years.
Now we’re building our own venture arm with @frontierheroes - so it was a special treat to host @BoostVC, @AdamDraper and the team at the Tower and @Superherohotel this week.
Visionaries who’ve been backing Sci-Fi since 2012 and the place where it’s being built in 2026. Excited to partner on many fronts. 🛸

I am running the very first "Founders (Don't) Cry" event next week in SF. Join me at @frontiertower for a night on the inner journey of entrepreneurship.

Partnership brewing, fangirl moment, and somehow just a normal Friday in SF.
Been using @boardyai since the day it launched (winter 2024). Today I finally got to meet @andrewdsouza and the team irl.
Now plotting AI-powered community stuff for @Superherohotel and the @frontiertower and something else. Stay tuned 👀
When builder communities join forces, special offers and magic happen.
Our friends at @summit are in Napa next week. Tickets are referral-only, but our community gets a fast-track to buy one last-minute, plus a special perk.
Comment @summit + @frontiertower to get a direct referral to the Summit founders and join.

@Summit Napa Valley, Oct 12–14 is the ultimate builders' workshop and we are exited to check it out this @SummitSeries gathering next week.
75% of attendees are CEOs, founders or investors. Building a tech company, a community, a CPG brand, anything with an identity? You leave with real tools and a network that takes you to the next level.
Frontier Tower is for the people building the future of cities.
Thank you @mattdorsey, @scsherrill, and @RafaelMandelman for the conversation tonight and Forrest Liu for moderating.
Officially a Yc-company producer through @frontierheros 🫡 check them out!
Best of luck at @ycombinator demo day and it’s such an honor to have had you participate in Batch 0 of the @frontierheroes ! Huge part of building startups is story telling. I remember brainstorming the foundation of this story with @KimAdams during breakfast @Superherohotel and it’s so cool to see how it evolved! Love it and excited to be part of your journey!
True
founder tip
if you’re building a web app right now, you need to start thinking about agents
In 5 years nobody will care about your UI, all you will need to build is an api key and some files.
everyone will have their own agent researching, buying, and building on top of these agentic layers.
you need to build your app in a way that it can be used and navigated by an agent effortlessly
just something to think about
We’re at @IcelandEclipse this week, talking about cross-disciplinary community and how we are building a permanent home for founders in San Francisco, with @Superherohotel as the landing pad. Inspired by pop-up city pioneers like @burningman, @zuvillage, @JoinEdgeCity - catch the talk by @katjayakov talking about what we are building with @frontierheroes 📷
What we want to create is a society of frontier tech aligned humans.
How we gonna get there:
- get awesome talent as members
- get funded teams to build in the tower by providing them with space and network
- Build incentives to follow processes to reduce entropy and manual work
build community
- Transform our community into a society
- Expand and build partnerships with nation states to build cities with reduced red tape
Promising!
The world has identified verifiable AI as a missing civilization-scale primitive. The core technical obstacle, practical zero-knowledge proofs, was considered impossible.
We solved it.
Today, we are launching @attestable, the AI Integrity Company, and announcing a $20M seed round led by @jaminball at @AltimeterCap and @YonatanMandelba at @TLV_Partners , with participation from @HalcyonFutures, Cerca Partners, @Weiner_Lia at Netz, @nickymontanaa at Zero Knowledge Ventures, @assaf_rappaport, Asaf Ezra, Nadir Izrael, Jon Coller, Eyal Manor, @OmerPerchik.
I wonder how many founders still read their code base..
I'm officially done reading AI-generated code.
It's been two weeks since I looked at any of it.
I think the IDE is officially on its way to the graveyard. The job is no longer about "writing code," so we need new tools that better reflect this new reality.
While reviewing the code, I realized my only complaints were stylistic, and I wasn't finding any obvious bugs anymore.
The more code I generated, the harder it became to keep track of every line. I found that my time is better spent designing ways to verify that the overall system works than looking at the code.
State-of-the-art coding agents are better at writing code than I'd ever be, and I'm going to stop pretending otherwise.
I still think these coding agents can't go too far without an experienced human guiding them, but we're past the point where we need to check every line of code.
Is it possible to prove simulation theory right?
The Chinese just made a one billion agent simulation — and in 14 hours of running it, they’ve already sent 4m agents to re-education camps! 🥁
Seriously, we will soon be able to create an AI simulation of planet Earth in which the agents are conscious, believe they are human, and won't know they are in a simulation.
Take from that what you will!
Did you know that after 60 minutes of inactivity Claude needs to reread your entire chat history?
If you left your coding agent alone for more than 1h, don't hit continue. Open a new session.
Send the exact same message. While you're working, it costs 1x. After coffee, 1.3x. After a call, 1.6x.
After lunch: 13x.
The cache holding your session expires at exactly 60 minutes, and your first message has to rebuild the whole thing from scratch.
A new session costs 4.5x. So before you walk away: "summarize where we are." After lunch, paste it into a fresh window.
Measured across a month of my own Claude Code — 110 sessions, 46,580 turns.
If you've been curious about Frontier Tower now's the time.
Come to our Open House Tuesday August 4th - expect tours, finding the floor that calls to you, & of course drinks & conversations.

@frontiertower in sf is the physical proof this is now a scene. 16 floors of a vertical village entirely dedicated to the people building this future, from biotech to crypto to network states. exit culture thrives there. we have to see it for ourselves.
