IMPORTANT: If you are an entrepreneur with subscription expenses you cannot figure out how to cancel or reduce and now you continue to get billed for things you have tried to cancel or reduce…. Please retweet this!!! Stand up for startups @stripe ! #helpUsStripe

Every founder I have met will raise at market valuations and in frothy markets raise too much. So Yuri’s well intentioned advice is basically never followed. More useful advice, raise at top of market and spend as if its bottom of market. Then you can easily cover a downturn.

We're looking for entrepreneurial scientists to join our team at Intercept (part of Public Goods @stripe)! Come join me and @nanransohoff @jmazz_1 on our quest to radically reduce the burden of respiratory viruses!

Big thanks to @NYSE and @Nasdaq for supporting our launch yesterday. Who is going to open the first stock exchange in space? @TerraFirma_Inc is willing to be the first IPO on Mars

Today, we’re announcing that we’ve raised $115 million in funding, including a $100M Series A led by @kleinerperkins. America has lost the ability to build, and we’re here to restore it. My co-founder, @NoahMcGuinn, and I left our jobs at @SpaceX , where we worked on programs including Starship, Starshield, and @Starlink, to build a company that will solve construction’s greatest challenges. Infrastructure is the foundation of civilization, and construction is the precursor to innovation. If America wants to build a brighter future for the next generation, we have to make it faster, cheaper, and safer to build. That’s where @TerraFirma_Inc comes in. We’re a new type of company, a robotic construction company that builds the full technology stack needed to deliver an order-of-magnitude improvement in one of the world’s oldest, largest, most important, but least efficient industries. We are building technology that expands what’s possible in construction on Earth, and then we'll use that same technology to build megastructures and colonies on the Moon and Mars. We’ve made tremendous progress over the past year, growing the company more than 10x in the last 12 months. We are performing projects across the world. By the end of October 2026, we are on track to operate 3 of the top 3 largest robotic construction fleets in the world, each on a different continent, bringing unprecedented speed, scale, and efficiency to some of the world’s most complex critical infrastructure projects. This funding will allow us to step on the gas and scale our manufacturing, software, operations, and construction deployments, including work on massive commercial and government contracts. We’re building the future of construction right here in Austin, Texas, and scaling it globally. If you want to be part of the team changing the world, now and on Mars, join us. Our Series A was led by Kleiner Perkins, with participation from Bain Capital Ventures, Glade Brook Capital Partners, BANNER VC, Saga Ventures, Trust Ventures, Definition, PEAK6, Magnetar Capital, and Ravelin Capital. Huge thanks to all of our angel investors, friends, and family who have helped and supported us throughout this journey. Apply here: jobs.ashbyhq.com/TerraFirma-…

Someone please create a human version of @YouTube , zero bots and zero slop allowed. Will pay $50 a month to get a guarantee I will never click on slop again. @YouTube sucks now.

PS, our crack marketing team also updated the website this week and it might be the coolest thing I've ever seen. aalo.com

Tomorrow is a big day for Aalo, and the future of clean energy on Earth.

Stills from @WHOSTP Director Michael Kratsios touring Aalo's CTR Facility, marking the 1-year anniversary of U.S. nuclear EOs.

Episode 3 of "Critical Thinking" is live: Inside the Aalo-1 Core. @yasir_fission sits down with Aalo engineers (and resident PhDs) Firas Abdullatif and David Jaluvka for a dive into reactor physics, the Aalo-1 core, and the designs choices that went into it. Firas and David walk through Aalo's combination of UO2 fuel, liquid sodium coolant, and a graphite moderator, and the tradeoffs that came with each. You'll also learn about reactor physics from the ground up: how fission actually works, fast vs. thermal spectrum reactors, why HALEU supply chain matters, and how neutronics, thermal hydraulics, shielding, and manufacturing all have to come together to make a reactor real. If you caught Episode 2 (sodium coolant), this picks up where that left off. Link: piped.video/7DaZw_fzD2E

In the 1980s, the world added ~230 GW of nuclear capacity. (in 10 years). A new reactor connected to the grid every 17 days on average. Insane.

Aalo has received DSA approval from DOE for our 10 MW reactor, zero-power criticality! This is the equivalent of an NRC license in DOE space. We've been working towards this milestone at Aalo for 2.5 years. This was a very ambitious project under the DOE reactor pilot program for a bunch of reasons: ➡️ 10 MW, commercial-scale system. This is a system with the full-scale amount of fuel, moderator, controls, etc, necessary for powering AI data centers. Proving out this supply chain is a big deal. In the coming weeks we'll be taking it to zero power criticality, and then going to full-power operation in the months that follow. We'll be getting the factory set up in parallel to mass-produce it. ➡️ Built everything ourselves, from scratch. We started with a green field, and within 4 months finished the building, facilities, policies & procedures, reactor, shielding, instrumentation, control, etc. People thought this would be impossible to do on this timeline for a reactor of this size, but we've done it. Hyperscalers care about speed, and we're showing that moving fast is possible at commercial scale. ➡️ Achieving criticality before July 4th. We set out to ensure we met the president's order, and we are on pace to do so. We only started hiring at Aalo 2.5 yrs ago. It was questionable how realistic it was to take on all of the above while being one of the younger nuclear companies, but we are on track to pull it off. Insanely proud of the team for all the hard work, nights and weekends that went into this. Full blog post will be linked in comments.

We need a @YouTube alternative that has a hard no AI slop policy before we can’t differentiate between AI and human content. Once we can’t, we are at the endgame.
