It’s time to build!!!
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.

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.

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.

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

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.
NEWS: Larry Page and Peter Thiel are making moves to leave California by the end of the year to avoid a possible billionaires tax that could hit them where it hurts. With @RMac18 @hknightsf. nytimes.com/2025/12/26/techn…

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.

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.

Built by American defense technology startup Anduril, Fury operates almost entirely by itself, carrying out mission plans and adjusting its flight without human input. "These fly out ahead of manned fighters, and they're able to find the enemy first, be able to engage the enemy well before a manned fighter has to be seen or is in range,” explains CEO Brian Schimpf. cbsn.ws/43jnUx6

Our greatest enemy continues to be ourselves.
Excellent job Lina Khan, you successfully destroyed iRobot, a company that Amazon wanted to purchase, but you blocked it for fear of a creating some kind of robot vacuum monopoly. Now which companies are winning? Well of course Roborock, a Chinese robot vacuum company that's flooded the US market and has better infrastructure and development. Another example of our own government destroying our own companies for the benefit of foreign competitors.
