@PeterL4e Welcome back 🚀🚀🚀

It’s time to build!!!

[Fredrik Hjelm 🇸🇪 @FredrikHjelm4]

Today we're launching @pitdotcom, with $16M funding led by @a16z.

For ten years at Voi and other companies I watched something that drove me crazy.

Smart people hired for their judgment, spending evenings reconciling data between systems that were never designed to talk to each other and chasing approvals over email at 11pm.

Work that had nothing to do with why they joined.

So we started building custom AI systems internally to take that work off their plates.

Across Voi and Klarna the founding team had been doing this for years, because nothing on the market could actually do the job.

The systems worked, but each one was a fragile one-off we couldn't hand to anyone else.

Pit is what we wished existed back then.

A platform that learns how your business actually works and builds the AI systems that run it for you, with enterprise security and governance from day one.

[Marc Andreessen 🇺🇸 @pmarca]

Every security flaw discovered by AI was there before AI, waiting to be discovered either by people or by AI. The world has never been good at securing computer systems; finally with AI we are going to get good.

The highest quality video of the moon was just released… this is so beautiful.

🇺🇸The brave Colonel is coming home after 48 hours of survival in hostile conditions. To the brave men that risked their own lives God bless you. Never leave comrade behind. Well done warriors.🇺🇸

[NASA @NASA]

We see our home planet as a whole, lit up in spectacular blues and browns. A green aurora even lights up the atmosphere. That's us, together, watching as our astronauts make their journey to the Moon.

[Katherine Boyle @KTmBoyle]

Great to see this. Gwynne Shotwell should be a household name. One of the most impressive business leaders of our time.

Meet Meridian: Turn Hours in Excel into Minutes
If you work in Excel, Meridian is built for you.

Meridian works with companies like Decagon, OffDeal, a top investment bank, and other financial institutions. We’re an AI-powered workspace that automates Excel modeling work with full traceability back to source data.

We raised $17 million in seed funding, co-led by @a16z and @TheGP to bring @MeridianAgent to more finance teams.

“We will invest in the best and the brightest entrepreneurs and help them to build generational companies. In doing so, we will work doubly hard to make sure the benefits go to America, the American people, and our many friends and allies around the world.” @bhorowitz

California is on a path to self-destruction. Hollywood is already toast and now the most productive entrepreneurs will leave taking their tax revenues and job creation elsewhere.

And then the Democrats highlight @CAgovernor Newsom as a great leader. Crazy.

[Jeff Dye @JeffDye]

😂. Who made this. This is great.

[Garrett Langley @glangley]

I'm incredibly proud that Flock Safety played a key role in working with first responders to find the suspect in the Brown and MIT murders.

America cannot tolerate tragedies like what we saw at Brown and MIT this past week. The single best way to curb crime is to make sure would-be criminals know they'll be caught. Excellent intelligence is the only way to make that a reality, and we intend to continue using technology to make sure our law enforcement are empowered to do their jobs.

[David Ulevitch 🇺🇸 @davidu]

This company and the people behind it are special. And deeply patriotic. People don’t understand that only America is organized in a way to wield absolute military superiority responsibly. We cannot allow our adversaries to have the upper hand.

[martin_casado @martin_casado]

Our greatest enemy continues to be ourselves.

The biggest infrastructure supercycle in history is here.

We are building the foundation of intelligence itself, with tools, models, silicon and light.

This is our moonshot.

Excited to present Runtime 2025 from @a16z AI x Infra.

Deel has raised $300M at a $17.3B valuation

We started about 6 years ago, struggling to even make $10K.

I've never shared this before because of how embarrassing our start was.

The story of how we went from $1K to $1B and the advice I'd give to my younger self:

We’re thrilled to be co-leading @Kalshi's Series D.

Prediction markets have established themselves not only as a new asset class, but as an extremely useful tool for predicting the future. And Kalshi is the leading company in the space. Not only does it have more volume than every other prediction market combined, but it’s the fastest growing tech company in the world outside AI.

Kalshi also announced today that they've expanded globally to 140 countries, making them the world's only unified global prediction market.

We’re excited to partner with @mansourtarek_ and @luanalopeslara as they scale this category-defining, world-changing company.
