@joshelman 👋

@Hadley Hi

Using Twitter today is like going to an event you really didn’t wanna go to because it was just gonna be full of randos and annoying people, then showing up and it’s a bunch of people you actually wanna hang out with

@swbarns Actually one is apparently on the way based in response to all my complaining

@Hadley She needs to buy you a “man bag” to keep your phone and wallet.

My wife loves to buy me fashionable pants with pockets so shallow they're basically decorative. Apparently there's a whole category of brands for men who want to look great while fishing their phone out of the back of an Uber.

@JamesUlan100 I wear very carefully

@Hadley Do you wear them or pockets too small?

@ashl3ysm1th Lol

@Hadley humblebrag my wife loves me

@praneshbuilds Great news for uber drivers who want to spin up their own neocloud

@Hadley u can fit H100s in those pants actually

Satya's right that enterprises should own their intelligence stack. It's also the perfect pitch for Microsoft, who'll sell you the tools and run it all on Azure. What they really fear is you outsourcing your intelligence to the model labs instead.

I believe Phia was also taking credit for sales it didn't drive at this deli

this makes more sense now

@business I'd like to submit this for your investigation

Phia — the buzzy shopping app co-founded by Bill Gates' daughter, Phoebe — is claiming credit for online sales it didn’t actually drive, a Bloomberg investigation found. Read our exclusive story: bloom.bg/4wErGxe 📷️: Dia Dipasupil/Getty Images

Thank you to our dear friend @fnthawar, Head of Engineering at @Shopify, running an org of some of the world's best 3000+ engineers, for speaking with our founders yesterday at @EniacVC in SoHo. Six lines stuck with me: 1) Pairing an engineer with a weak model is like starting Bellingham over Messi. Shopify uses zero open source models for code. Only frontier. 2) They distilled one workflow down and cut costs from $30M a year to $1M. 3) Top engineers are up 2 to 3x. The bottom third is up maybe 15 percent. The gap is widening fast. 4) He wants teams of 12 to become teams of 4. Product, design, data, and eng, collapsed into one role. 5) Every interview now has three rounds. No AI. AI optional. AI mandatory. 6) Every PR still has one human name on it. That hasn't changed. The floor is rising but the ceiling is infinite. Even more bullish on the future of software. Thank you Farhan!

@Hiraweb3 Sf peeps

@Hadley who said nyc wasn’t a tech hub?

VCs: There’s no AI talent outside of SF Anthropic: we need a 16 story building full of people in NYC

@ashl3ysm1th @vermilionfund @DominicMadori @TechCrunch Amazing but not surprising! Excited to get to work with you more! Congrats!

Today @vermilionfund closed our $25M second fund. Still backing technical founders building for technical users in AI infra, security, and dev tools. 95% of my Fund I investors came back for Fund II. That's the number I'm most proud of. @DominicMadori from @TechCrunch wrote about our story techcrunch.com/2026/07/08/sol…

@arian_ghashghai That’s a great point

it was commonly accepted until 4/5 years ago in industry that NYC and Paris have an equal or higher density of ML talent vs SF the new line on “SF or bust” for AI imo is entirely instigated by VC interests (big VC structurally prefers geo-concentration, and ideally in SF)

The optimal number of founders on an initial seed pitch is typically 1 and never more than 2

LFG! 🇺🇸⚽

We’ve received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5. We'll begin restoring access tomorrow, and will share an update soon. We’re grateful to our users for their patience, and to everyone who worked with us on redeploying the models.
