Today, we are announcing that we have doubled our AUM @LongJourney by closing a $181,818,181.8 fund. I can’t be more proud of what @cyantist and I dreamed up 5yrs ago. For both of us this business has always been deeply personal. Today I would like to explain why it matters to me.

This captures the spirit of @LongJourneyVC so well.
when the magically weird collides with ambitious, radical action, you get the kind of improbable ideas that built san francisco that spirit was on full display as we hosted an evening alongside @LongJourneyVC @cyantist and @LeeJacobs shared their investment theses and why backing ideas others dismiss as weird can be a source of alpha

We smuggled an Argentine parrilla onto our patio for an asado with our SF community. It didn’t fit through the front door, so we got creative with a ladder and some muscle. First time cooking steak and pineapple hanging over an open fire. I'm giddy like a kid at Disney. What I love about asados is that they’re a weekly anchor, usually Sundays in Argentina with family and friends. They create sapce to keep relationships going in a way one-off dinners don’t. Kind of like the Shabbat dinners SF tech has rediscovered :) My most moving asado memories are from Buenos Aires, where complete strangers invited me into their homes, cooked for me all afternoon, and treated me like family. An OG recipe for connection.

After six years in stealth, Atomic Machines is out. Our mission: on-demand, universal command of matter. First beachhead: the Matter Compiler, an AI-native manufacturing system that builds working micro-machines from code alone. No per-product tooling. No process development. Different code, different machine.

Don't confuse motion with progress. Many startups are very busy, but they aren't actually moving the needle. Velocity is speed with a specific direction.

I’ve listened to every interview Chase has given- and this is by far the best yet. Chase boils down the seemingly complex @CrusoeAI in a way that I’ve never heard him do before, while also getting a glimpse of his warrior mindset. h/t @HarryStebbings for shining the light.
Why the AI infrastructure market is just like the energy market “There are very interesting parallels between AI infrastructure and the energy market. There are a lot of different ways to make money across the value chain. What Crusoe is focused on doing is building an AI super major, vertically integrated across upstream, midstream and downstream. Where the margin accrues is going to move around. We are seeing a similar phenomenon play out in AI, where our margins are going to move around across electrical data centers, chips and services.” @ChaseLochmiller Love to hear your thoughts @GavinSBaker @branninmcbee @stephenbalaban @Electron_Cowboy

This team is relentless. This video is also hilarious..
Thrilled to announce @getOuterSignal has raised a $22M Series A. A year ago, @zachzelner and I saw an opportunity to revolutionize personalization. We spun out a tool he’d built into a company, and got to work. In the time since, we’ve gone from a few early customers to thousands, from 2 team members to 25, and created an entirely new frontier for how businesses can understand and market to their customers. Our team has built a robust platform, trained internal models, conducted industry-leading research, and onboarded thousands of companies we’re proud to work with. So, this raise is meant for one thing only: to keep shipping, faster than ever, the very best products for the consumer businesses we power. Ecom, hospitality, mobile apps and beyond: OuterSignal is here to supercharge the way companies connect with consumers. As founders, we’re humbled, grateful, and truly just getting started. Try us for free at OuterSignal.com. And if you’re an A-player ready to work on something ambitious and enduring, we want to meet you. DM’s open. Onward 🚀

This is just next level.
Mark really buried the lede… In his 3rd tweet in the thread about building an enterprise AI business, he notes that he poached the ceo of a $30B public company (MongoDB) to lead it

SHOT ON MRI
Fun demo today: While traveling, I remotely drove an MRI in our lab to write AION into a tube of water The 'ink' lasts seconds: the letters are physically written into the magnetization of the water protons (aka SPAMM MRI)

When it rains, it pours @ADoricko and team on roll like none other.
Rainmaker has raised $100M to become the world’s best lab for weather modification and atmospheric science. Thank you @noavctech @upfrontvc @DCVC @lowercarbon @DreamVenturesVC and other visionary partners. We are aggressively hiring and scaling our research org to create a flywheel of atmospheric data collection, synthesis, understanding, and intervention. We will solve the weather and we will set the stage for the terraformation of Earth. More in my essay below.
