Alex Hartz reposted thisAlex Hartz reposted thisThe United States Air Force and the Defense Innovation Unit (DIU) have selected Antares to deploy a microreactor at Joint Base San Antonio under the Advanced Nuclear Power for Installations (ANPI) initiative. Critical missions depend on resilient power. Our R1 microreactor — sodium heat pipe-cooled, TRISO-fueled, and built to operate for years between refueling without connection to the commercial grid — is purpose-built to deliver it.

Alex Hartz reposted thisOur work with ESPN involves T-Rex races, stein-holding championships, and competitive sign spinning. The Ocho--ESPN's home for the wonderfully absurd--has decades of archive that's never made it to streaming or FAST distribution. Not because the content isn't compelling, but because the music was licensed for the original broadcast and delivered as a single mixed master, with no stems. There was no way to separate the soundtrack from the commentary. A huge portion of sports media sits in exactly this state. Music cleared once, for one distribution window, now making decades of footage unusable across so many places where distribution now exists. AudioShake has been working with ESPN on exactly this — pulling music out of mixed audio without original stems, so the commentary stays, the crowd stays, and the licensing problem goes away. What started as an archive question has grown into how ESPN thinks about doing more with its broader catalog. A big shout out to the Disney Accelerator, who first introduced us to the ESPN team. Thank you to Brett O'Neill, Bonnie Rosen, Kevin Lopes, David Min, Kate Mitchell, and everyone at ESPN, who brought us a specific, real problem and then built towards it with us. In the name of hot dog eating contests, slippery stairs races, and cornhole championships, onwards!

Alex Hartz reposted thisAlex Hartz reposted this🎙️Our portfolio company AudioShake just launched #DialogueRT, and it's a genuine technical milestone for anyone working in live broadcast. Bad captions. Missed ref calls. Muffled commentary swallowed by crowd noise. These aren't just annoyances, they're the result of a fundamental audio infrastructure gap. Live broadcast audio chains need to operate within a 9-15ms latency window to avoid perceptible lip-sync issues. Until today, no AI dialogue isolation model could work inside that window. The best existing tools run at around 42ms. Good enough for post-production, not good enough for live. ⭐ Dialogue RT runs at 11ms end-to-end and it's doing true isolation, not noise suppression. That means pulling a clean speech stem out of a live mixed feed (crowd noise, PA bleed, stadium chaos and all), rather than just reducing unwanted sound within the mix. AI-Media is already running it in production, which is a pretty good signal of how ready this is for real broadcast environments. Congrats to Jessica Powell and the whole Audio Shake team, this has been a hard problem for a long time and they cracked it. 🚀 #MediaTech #AudioAI #ThomsonReutersVentures #LiveBroadcast CC: Tamara Steffens, Joseph Dormani, Josef Najm, Jack Benedict, Alexander Carvalho, Karen Lopez, Anushka Khetawat

Alex Hartz reposted thisAlex Hartz reposted thisAudio has historically been read-only. Labels, studios, and broadcasters could play it, distribute it, stream it. But they couldn't separate it, search it, or work with it at the component level — not reliably, not at scale. That's the infrastructure gap AudioShake was built to close. Today, we process hundreds of millions of minutes annually across Universal Music Group, Warner Music Group, Disney Music Group, NFL Films, and AI-Media–and many, many more. Fred Vogelstein at Crazy Stupid Tech wrote about what it took to build — and why it matters. Link in comments.

Alex Hartz reposted thisToday, U.S. Department of Energy (DOE) approved our Documented Safety Analysis (DSA) for the Mark-0 reactor. This was the first-ever approval for a new reactor. This marks the FINAL regulatory approval, confirming the reactor's as-built safety basis. Now, we enter the final phase of readiness, fueling and commissioning the reactor. I want to thank the Antares team, Bob Boston, our partners, Idaho National Laboratory, especially Justin Coleman's team and National Reactor Innovation Center | NRIC, and Rian Bahran, Ph.D. Seth Cohen from U.S. Department of Energy (DOE) headquarters. Neutrons coming soon!Alex Hartz reposted thisThe U.S. Department of Energy (DOE) approved our Documented Safety Analysis under DOE standard 1271, a major step in DOE's advanced nuclear reactor authorization pathway. This milestone represents the culmination of design, analysis, subsystem development, and integrated testing across the reactor, controls and supporting systems. It confirms that our safety framework meets the standards required under DOE authorization. We have entered the DOE Readiness process. After the Readiness Review is complete, we will commence nuclear operations. Rigor, discipline, and collaboration between the Antares team, DOE, Idaho National Laboratory, and National Reactor Innovation Center | NRIC made this milestone possible. Onward.

Alex Hartz reposted thisAlex Hartz reposted thisAgents are only as good as the tools they use. An agent that exclusively uses a browser as a tool in production workflows is destroying your user experience. It doesn't matter how fast or how good the computer-use models get... they're still chained to an stone-age product built for humans... a browser. Agents give our products superpowers. They can feel so fast its magical. Chaining them to a browser that runs slowly and breaks frequently feels almost cruel to our future AGI overlords.

Alex Hartz reposted thisAlex Hartz reposted thisAnnouncing Shine Luminaries Artificial intelligence is reshaping every industry, and venture capital is no exception. We can now do in minutes what previously took days, and machines largely do it for us. This seismic shift has catalyzed us at Shine Capital to rethink how we work so we can best meet the moment. Our belief is simple: as AI automates cognitive labor, tomorrow’s builders will be driven by individual agency, creativity, and judgment, all paired with unique insights. These insights come from being native to new technologies and in constant dialogue with peers. We want to build the future together with the brightest minds. So today, we introduce Shine Luminaries, our new approach to collaborating with young builders as investors. Luminaries will provide Shine with insight into fresh ideas, facilitate relationships with emerging talent, and build new AI tooling to help scale these efforts. In return, Shine will offer unprecedented access to investor thinking and our collective networks, as well as visibility into the full venture investment process. We will provide a stipend and share economics with Luminaries for investments they source. Luminaries will work with Shine while building their own companies or projects. This apprenticeship will give builders a lateral perspective of the market and access to our resources as they pursue their individual passions and build in the trenches. For the inaugural group, we are bringing on three to five luminaries, each with unique skills and expertise in areas of mutual interest. This program is dynamic – the world is changing fast, and we will change with it. We will evolve the program to meet the needs of Luminaries while creating value for Shine. If you are interested in Shine Luminaries, please share a bit about yourself and your passions with luminaries@shine.vc. The future is bright.

Alex Hartz reposted thisAlex Hartz reposted thisSupergood started off as an observability company. It was intended to solve a real problem I dealt with firsthand: Why are there so many f**king expensive and broken third-party APIs at my company? And why do I have to deal with them? So we got to work and built the first version of Supergood: a small code snippet you drop in to automatically monitor and classify all your company's APIs and flag any issues. But, it turns out that simply pointing out problems is not nearly as valuable as fixing them. We had one customer who REALLY liked our product, and a TON of people who did not. I used that one customer's excitement to build the version of Supergood that people actually want -- while staying true to our original observability thesis. I went into great detail about this with my friend from undergrad at Carnegie Mellon University, Karina Chow, on her new podcast, Edge Cases! https://lnkd.in/g7JqAqTpEp. 01: Reverse Engineering the Rules w/ Alex KlarfeldEp. 01: Reverse Engineering the Rules w/ Alex Klarfeld

Alex Hartz shared thisiVerify is the leading EDR and lab for mobile device security. See below for breaking news from Rocky Cole.Alex Hartz shared this🚨First Mass iOS Attack by E-Criminal Group Uncovered People of a certain age remember "EternalBlue" and the subsequent WannaCry and NotPetya attacks, cybercriminal operations facilitated by leaked US government tools. I've predicted for years that mobile devices would have their "Eternal Blue" moment. That moment has arrived. iVerify has just observed -- and caught in the wild -- a tool engaging in mass exploitation of mobile devices, including iOS, by a criminal group. This sophisticated exploit framework, dubbed Coruna by Google, appears to have originated from a nation-state before leaking into the hands of cybercriminals and other nation state adversaries. What You Need to Know: 📍 Criminal groups are using a "watering hole" strategy, targeting users on cryptocurrency and pornography sites. 📍Once a device is silently infected, the malware automatically steals cryptocurrency and harvests sensitive personal data, such as photos. 📍iVerify assesses that the exploit chain has similarities to frameworks previously developed by threat actors affiliated with the U.S. government. 📍Unlike traditional spyware used for targeted surveillance, this campaign represents a move toward mass deployment. 📍Containers, like MaM and MDM, do not protect against this threat, nor do legacy MTD providers who lack system level telemetry. 📍The iVerify EDR platform robustly detects this threat. We're hosting a virtual town hall at 4pm today to brief the community on our findings. Link to the town hall and our findings in the comments.

Alex Hartz reacted on thisAlex Hartz reacted on thisWe had our monthly AI All Hands at Pathpoint today. How we do these: 1. Deep demos of AI in the business 2. Open mic show and tell of how people are using AI at work or at home, bar very low can be super simple 3. Hands on working groups This is meat and potatoes stuff -- we would rather roll our sleeves up and get 3/4 more people, after each all hands, with the right CC/Cowork setup or a more finely tuned implementation than present some grand plan on slides. Here's what we demo'd today: 1. Dan Clark and Josh Rackley showed off our Pathpoint MCP and a few underwriting workflow use cases. 2. Liz Dresher demo'd the newest updates to Ellie, our AI SDR, who is now producing revenue after going live in February. We're also still the fastest growing wholesaler, profitable, and adding more products and clients every day. Come join us!

Alex Hartz liked thisAn A1 broadcast engineer tried Dialogue RT at our booth this week and actually gasped — everything but the voice, gone in real-time That was #NAB, basically. A media company walking us through their archive problem — hours of footage blocked from streaming because of music baked into the tracks. A post-production lead showing us how they're using us across localization — pulling dialogue, music, and effects apart so they can ship the same show into a dozen more markets. Areas for improvement: — The convention center remains impossibly long. Looking forward to its rebuild in 2130. — The mixer who came up to the booth and asked to speak to someone technical because — and I quote — I was "too pretty to understand audio" (yes, in 2026). Thanks to everyone who stopped by, and to the team that made it run--Suzanne Kirkland John Ivers April Anderson Krista Campbell Troy Skinner Stephen Oliver

Alex Hartz liked thisAlex Hartz liked thisSome of the most compelling companies in the latest round of Founders You Should Know nominations aren't just based outside San Francisco — they're building things that only make sense to operate outside it. Halter has GPS collars that live on actual cows. Starcloud is putting data centers into orbit. Mariana Minerals is running operations across Texas, Utah, and North Dakota. The frontier labs aren't going to wrangle cattle or launch satellites anytime soon, which means the opportunity map is expanding fast for founders willing to go where the problems actually are.

Alex Hartz reacted on thisAlex Hartz reacted on thisFor a 2026 Super Bowl ad, ESPN wanted to use Phil Simms’ iconic “I’m going to Disney World.” There was one problem: the original clip had music baked into the background. Licensing the full clip—for just a few seconds—would’ve been cost-prohibitive. So instead, ESPN used AudioShake to separate Simms’ voice from the music—and licensed only what they actually needed. Our tech was able to distinguish Simms' voice within the mix, even with many competing voiced elements, like crowd noise and the singer in the background. That same issue exists across a huge portion of sports media. A lot of archival footage includes music cleared for the original broadcast, but not for streaming or social — which makes much of the archive unusable on modern platforms. Separating the music makes the archive liquid again. The commentary stays, the crowd stays, and the licensing problem goes away. What started as a one-off fix is now being applied across their broader media workflows. Full case study in the comments, and a big shout out to the The Walt Disney Company Accelerator for introducing us to the ESPN team.
