I've been having such an amazing time with Claude Code I wanted you to be able to have my *exact* skill setup: Introducing gstack, which you can install just by pasting a short piece of text into your Claude code

210 days ago, @naturalpay was just a one-pager and a memo. Today, we’re coming out of stealth. Natural is the agentic payments platform powering frictionless money movement between agents, businesses, and consumers. Wallets. Payments. Ledgering. Routing. Identity. Compliance. Credit. Observability. Risk. Everything needed to move money. Engineered for agents and designed for humans. These primitives give you the ability to transact without becoming a payments expert or stitching together a dozen fragmented tools. Huge thanks to our team of 10 (soon to be 25), our early investors, and the supporters who believed in this vision from the start. If you want to help shape how money moves over the coming decades, we’re hiring. And if you’re building agents you should probably be moving money too. Reach out. Read more about Natural and the products we’re launching in the blog below. natural.co/blog/introduci…

This article explains clearly why the proposed wealth tax would be so damaging to California. It's not an accident. It's *designed* to be damaging. astralcodexten.com/p/seiu-delenda…

Big congrats to @maxpollard415 and team on the monster seed from A16z. Just like drones on a battlefield, agents wielded by small teams of attackers pose an entirely new kind of security threat. Cotool helps security teams fight agents with agents.
Max Pollard@maxpollard415

Excited to announce that @cotoolai has raised a $7.4M seed round led by @a16z to build the agent operating system for security teams. Threat actors now scale with tokens. Campaigns that used to require a coordinated team can be run by a small group with the right model harness. Defense has been absorbing that hit with the same playbook and the same headcount. We built Cotool to make defense compound in the same way. Grateful to the team at @a16z, @ycombinator, @WndrCoLLC, @homebrew, and our angels from Okta, Ramp, Cloudflare, and others who've lived this problem firsthand. If you’re a security practitioner looking for more leverage in the AI age, come see how Cotool can help!

This is insane. GPT 5.4 in our Excel engine just made a raytracer in Excel. Completely native with Excel formulas. We took all our knowledge about OOXML we learnt from building our DOCX engine to build the world's best excel engine harness for agents.

It never really made sense to me that a stock exchange would close over the weekend or only cover a single geography. They’re obviously a relic of an offline era. Shouldn’t there be a global, 24/7 equities exchange? That’s what QFEX is building.

QFEX is an exchange built from the ground up to work exactly the way you'd expect: open 24/7, no brokers or middlemen. It's a hugely ambitious idea created by two of the strongest founders I know. Today they are announcing their $9.5m raise led by @yuris at GC. Congrats, guys.

I support Ethan Agarwal against Ro Khanna Khanna has turned his back on the people of CA17. He said he would help tech, that his predecessor did nothing but name a post office. We would rather Khanna do that than work to destroy prosperity with national asset seizure.

Nice to see a pro-Silicon Valley Democrat challenging the guy who is currently mis-representing Silicon Valley. sfchronicle.com/politics/artic…
