SpaceX IPO basically boils down to people with spreadsheets debating with people who believe in Elon.

History suggests the spreadsheets have been wrong when it comes to Elon companies.

[Tesla Owners Silicon Valley @teslaownersSV]

“It is certainly hard to believe that a little company (@SpaceX) that started in a warehouse in El Segundo is now going public with the largest IPO ever.”

You are far more dangerous to your startup than competitors are. A hundred times more startups die from poor execution by their founders than are killed by competitors.

Hands down, the best personal unboxing of stablecoin cards so far goes to @Cypher_HQ_
Worth looking into this 60-second video to see how much is inside this box.

Shoutout to @coinbase, @Cypher_HQ_ and @cryptocom for having 3 products I've used over the last 4-5 years with regards to spending your crypto and digital assets onchain. Keep beating the banks!

[Nicolas Dessaigne @dessaigne]

My advice to founders in 2026: spend tokens, not headcount.

Record everything. Make your company queryable. Build self-improving loops.

Before long, AI won’t just help you operate your company. It will make it self improving.
Don't think AI adoption, think AI transformation.

This is the biggest shift in how startups get built since cloud computing.

@prajitn @circle @jerallaire Congrats 🫡

[Aaron Epstein @aaron_epstein]

The biggest hack I’ve seen for founders to close deals faster: just show up.

Get on a plane, fly to their office, meet in person, bond with the whole team.

Instantly replaces weeks of zoom calls.

[Tom Blomfield @t_blom]

A lot of people are trying to figure out recursively self-improving companies right now.

I break down what we’re seeing at YC.

[Y Combinator @ycombinator]

Announcing YC Crypto deals

We're now providing crypto deals to support fintech builders funded by YC: support on tools like wallets, onramps, audits, blockchains, onchain data.

Most AI workflows today still break at one point
it's PAYMENTS

Workflows can browse, compare products, fill forms, and reach checkout but a human still has to step in with a card.

We removed that bottleneck.

In this workflow powered by @mastra & Cypher Agent Pay, it:
→ verifies the order amount
→ checks payment conditions
→ generates a one-time-use virtual card
→ completes checkout autonomously

Your workflows no longer stop at checkout.

[Cypher💳 @Cypher_HQ_]

The missing piece of agentic AI just dropped!

Introducing Cypher Agent Pay 🤖💳
The first payment system built exclusively for AI agents.

Your agents can now pay for anything.
Autonomously & securely. 24/7

We're giving our first 500 builders up to 30 FREE cards each with zero top-up charges.

[Cypher💳 @Cypher_HQ_]

Introducing Cypher Business🌏

The business spending account built for crypto-native teams.

Traditional corporate cards weren't built for you.
Slow to setup. Rigid limits. Zero crypto support.

Cypher Business fixes all of it from day one.

Zero setup fee. Zero annual fee.
Exclusively for the first 100 businesses.

[Rivenna Vale @rivennavale]

What I love about the @Cypher_HQ_ card is the auto top up feature

You can set when it does (in my case when it goes bellow $100) how much it does ($500) and until when and how many times it will top up the card

It actually saved me from embarrassment a couple of times when I went shopping

[Cypher💳 @Cypher_HQ_]

Most crypto apps → 6 steps to get your transaction history

Cypher Agent → one sentence. Done✅

That's it. That's the whole thing

This is the new way of banking onchain

@naval This is super cool. Congrats 🎉
