Jon Gelsey shared thisDevZero launched a tool last fall that does Kubernetes automation to decrease cloud costs and increase reliability. They do this by automatically rightsizing workloads and autoscaling infrastructure based on actual workload usage instead of static resource definitions. This is impossible to do manually unless engineers are sitting and watching dashboards 24/7 and applying helm and terraform updates constantly. The team there is super impressive. https://www.devzero.io/ Expect to reduce Kubernetes infrastructure costs by 50%+ in a matter of weeks.Cut Kubernetes Cloud Spend with Live Rightsizing | DevZeroCut Kubernetes Cloud Spend with Live Rightsizing | DevZero

Jon Gelsey shared thisAI governance done right.Jon Gelsey shared thisWe spent decades perfecting deterministic software. Agents just broke the contract. Building large-scale data and ML systems at Rivian and Walmart Global Tech taught me that scale exposes everything. When you are managing critical infrastructure, "it works on my machine" isn't a strategy. You need predictability. But we are entering the Agentic Era, and the fundamental physics of software have changed. We are moving from deterministic code (where Input A always equals Output B) to probabilistic agents (where Input A might result in Action B... or Action C). For builders, this is thrilling. For the people securing the blast radius, it’s terrifying. How do you sign off on a "Go-Live" decision when your software can make up its own execution path? That is the problem my co-founder Anand Salodkar (ex-Security & Audit leader at Dolby Laboratories and EY) and I set out to solve with CompFly AI. We realized that you can't just "monitor" autonomy. You need to govern the entropy. We built CompFly to be the trust control plane that bridges the gap between the stochastic nature of AI and the rigid safety requirements of the enterprise. I’m incredibly energized to be back to building from first principles. This is just the beginning. Check out what we’ve built: https://compfly.ai/ 🚀 We are hiring. We are building a small, high-density team to solve the hardest problems in Agentic Security and Distributed Systems.

Jon Gelsey shared thisJon Gelsey shared thisAnnouncing Fastly and Macrometa partner to make every developer a superhero with stateful edge computing A few years back when Durga G. and I started Macrometa - we were filled with excitement and hope that the #edge would someday become a real #platform for building new #realtime stateful data driven apps and APIs that ran #globally closer to everyone. We envisioned a world where developers could use Macrometa and #edgecomputing to build global apps with double digit round trip latency anywhere in the world, with built in intelligence to solve complex data serving challenges like privacy, security, global scalability and geographical awareness. (in comparison to our current cloud native way - where we build apps in a single cloud region that is thousands of milliseconds per round trip away from users and data sources). In April last year we were proud to announce our partnership with Cloudflare and deep integrations between Cloudflare #workers and Macrometa's Global Data Network. Today we are excited to announce our partnership with Fastly and Compute @ Edge - Fastly's advanced next generation global serverless function as a service that runs on the Fastly global network. Together Fastly and Macrometa are enabling a new generation of serverless apps and APIs to be built on the edge that are 100X faster and 90% more economical than building on cloud. learn more - https://lnkd.in/dGnFQuwt We are proud to have industry leaders such as Cloudflare, Fastly, Linode, Cox Communications as partners in making edge computing a vibrant and powerful infrastructure for developers to build ground breaking new apps and digital services on.

Jon Gelsey shared this"Wars are expensive and need to be financed, one way or another. Don't let it be you."Jon Gelsey shared thisIndividuals and small businesses need to be extra aware of cybersecurity in the coming days, weeks, and months. Now is not the time to be clicking/tapping on stuff. And now is definitely not the time to be entering information into online forms unless you are 100% certain it's legit and someone with whom you've done business in the past. No, your CFO doesn't need you to wire funds right now. No, your bank doesn't need you to reset your password or unlock your account. No, you didn't win anything at Walmart. No, your grandchild has not been arrested for selling drugs. And, both your tax refund and social security check are fine. Wars are expensive and need to be financed, one way or another.

Jon Gelsey liked thisJon Gelsey liked thisWe keep finding 5%-10% utilization (the highest so far is 17%) in Kubernetes environments… VPs of engineering swear everything is "fine," but their reaction tells you everything you need to know about utilization ignorance. And let me drop the real story here, you won’t believe: sub-10% utilization is the new norm. Across multiple companies in a wide variety of sectors, abysmal Kubernetes optimization is now what we expect to see when DevZero is connected. This is what I see every day: 1. The number on the screen flashes 5%, 7%, 11%. Ugghh. 2. The room tenses. Someone says, “No way. Production isn’t like this.” 3. I think, “Okay, but still. Not even your non-production should be running at 5%.” 4. Then someone in FinOps joins the call and says, "Wait, what the hell? Why are we at 5%?" 5. Then the lead platform engineer goes, "No, no, no, we’re fine." But that sentence, "we’re fine," is the true villain. Your cloud invoice doesn’t care about utilization; it just wants your money. "We’re fine" really just means, "We’re okay with waste." And every day, idle compute is gobbling up millions of dollars. And of course, nobody is acting out of malice. Engineers don’t want to see 5% utilization. But this number comes from a lack of incentives, comfort, and an all-too-common (and infectious) “we’ll fix it later” attitude. One fix I would never suggest for fear of getting blasted by the engineering community: engineer comp moving with infra spend… Utilization denial would disappear fast! (And it would probably get fixed fast, too.) Of course, our world doesn’t work this way. But could a better balance be struck? Yes. And it’s up to engineering leaders to lead the charge.

Jensen Huang said something at #GTC2026 that I haven't been able to stop thinking about. 🦞 "Every company in the world today needs to have an OpenClaw strategy, an agentic system strategy. This is the new computer." Yes, the NemoClaw launch is very cool and I'll be trying it out as soon as possible (obviously). But what I think is even more interesting is what is really behind all of this. His keynote, the GitHub repos, social media hype, the billion-dollar infrastructure bets - We are living through a fundamental shift in how work gets done. We are moving from tools to agents. Can you feel it? A tool does what you tell it but an agent can decide what to do next. And after that. And after that. If that sounds like a small upgrade to you, you're thinking about it wrong, and IMO most organizations are still thinking about it wrong. Andrej Karpathy published autoresearch on GitHub earlier this month. One agent, one metric, one instruction: never stop, never ask for permission. It runs experiments overnight while you sleep and you wake up with 100 completed iterations. So what does that mean for us? The human's job shifts from doing the search to defining what's worth searching for. Jensen made another prediction. He said every engineer will have an annual token budget worth roughly half their base salary - so they can be amplified ten times. He called tokens the new recruiting currency in Silicon Valley. Not equity. Not perks. Compute. Access. Think about what that means. Compensation is starting to reflect not just what you know or how long you work, but HOW MUCH you can do with the intelligence available to you. That's honestly an incredible shift. Most leaders I talk to know something big is happening. Fewer have sat with the hard questions: How do we measure output when the process runs itself? Who is accountable for an agent’s decision? How do we manage a workforce where half the "employees" are digital agents? Those really aren't technology questions - they are leadership questions. And I haven't seen a lot posted about this yet. (And no - AI did not write this. I did.) Where is your organization on this? How have you seen companies building their agentic strategy and what does it look like? Drop your thoughts in the comments. https://lnkd.in/eEY_pWxs

As AI workloads eat up global computing supply, DRAM prices are surging like never before—creating major challenges for teams trying to plan out their data center spend. One of my portfolio companies, Mext, is addressing the largest cost component in the datacenter: server memory (DRAM). From being on the board of Redis for the last twelve years, I’ve learned a lot about the various aspects of this problem and approaches to solving them. Mext found a breakthrough, using new AI techniques, for dramatically reducing the amount of server-DRAM required to run applications, all while maintaining performance. It intelligently manages the server’s memory, keeping hot pages (i.e., those in use by applications) in fast DRAM and offloading cold pages (i.e., those less used) to a much less expensive memory tier (e.g., NVMe Flash). Key to the approach is ensuring cold memory pages that are about to be accessed by an application are back in DRAM before the application needs them or notices that they were gone. This is done without modifications to the application or the OS – so it can run in the cloud or on-premise. Mext thus allows applications to either run using less DRAM or keep their DRAM footprint but do more with it. They're hosting a webinar along with Fred Weber (former CTO of AMD) on Jan 22nd at 10am pacific time. You can register here: https://lnkd.in/gXe9GCeE

AI infrastructure has hit a power wall — and interconnect inefficiency is at the core. As bandwidth and connectivity requirements explode, copper is no longer keeping pace. Co-packaged optics changes that. Today, I’m proud to share that Ayar Labs has raised $500M in Series E funding to accelerate volume production of co-packaged optics for AI scale-up. I want to sincerely thank our lead investor, Neuberger Berman, and our new and existing investors for their conviction and partnership — including ARK Investment Management LLC, Insight Partners, Qatar Investment Authority, Sequoia Capital Global Equities, 1789 Capital, and our strategic partners AMD, Alchip Technologies, MediaTek, and NVIDIA. This funding fuels the next phase of our execution to: - Scale high-volume production and test capacity - Expand global operations, including our new office in Hsinchu, Taiwan - Deepen ecosystem partnerships across the AI and custom ASIC landscape - Accelerate the deployment of our CPO solution Thank you to all of our investors, customers, and most importantly, the Ayar Labs employees — your vision and execution make breakthroughs like this possible.

Quantinuum’s planned IPO is the moment quantum finally hits the public markets in grown‑up form. This isn’t another early‑stage SPAC story; it’s a full‑stack platform spun out of Honeywell, with trapped‑ion hardware that regularly tops industry benchmarks and a real software and applications business on top. By combining industrial‑grade engineering with production‑grade tooling in chemistry, security, and optimization, Quantinuum gives investors exposure not just to “qubits,” but to an integrated quantum stack that already serves enterprise workloads. For technical and business leaders, as well as investors, the key question now is how public markets will price a quantum company that actually looks like an infrastructure and software provider rather than a speculative science project. Whatever the final valuation, this IPO will likely become the benchmark for what “mature” looks like in quantum—deep IP, differentiated hardware, and diversified revenue experiments before ringing the bell.

Thank Dani Cherkassky Great piece on the architecture shift voice AI needs. The core thesis: cloud-centric voice systems fail in real-world conditions because they are too slow, too expensive to keep always-on, and deaf to spatial context. The solution is a hybrid architecture—fast, always-on edge processing (Spatial Hearing AI and Cognition AI) handling 80% of interactions locally, with cloud LLMs reserved for complex reasoning. But the Kahneman thesis runs deeper than the article suggests. System 1 and System 2 are not just useful metaphors—they reflect an actual biological sequence. Fast, intuitive processing (System 1) evolved first; slow, deliberate reasoning (System 2) was layered on top. The brain's architecture reflects this: spatial-acoustic processing happens in milliseconds at the brainstem and primary auditory cortex, long before language centers engage. Kardome is not just borrowing Kahneman as marketing. Their architecture is neurologically correct—it replicates the hierarchical, parallel, spatially-aware processing that makes human auditory cognition so robust. Here is the deeper point: hearing preceded language in human evolution, and spatial hearing preceded both. The mammalian auditory system evolved to detect predators and locate prey—survival functions that required sub-second latency and continuous environmental awareness. Language processing was layered on top of this infrastructure. Current voice AI inverts this evolutionary logic: it starts with language models and treats spatial audio as an afterthought. Kardome restores the natural hierarchy. 🙌 Danny Shapiro, Rory Sutherland

Mary Lou Jepsen holds nearly 300 patents. She founded four companies. And led hardware at Facebook, Google, Intel, and Oculus. Let’s rewind. In 1995, Jepsen co-founded MicroDisplay, where she pioneered components that would later power VR, AR, HDTVs, and smartphones. She led the full stack: from ASICs and optics to manufacturing strategy. Next came a senior technical role at Philips, where she contributed to early LED breakthroughs now found in billions of devices. In 2004, she joined Intel, becoming CTO of the Display Division, where she architected the company's next-gen HDTV efforts. But her name became globally recognized in 2005, when she co-founded One Laptop Per Child (OLPC). A global movement to bring ultra-affordable computers to children in low- and middle-income countries. The result: a ripple effect that led Google’s CEO to later call the Chromebook “the grandchild of OLPC.” Then, Jepsen spun out the OLPC display tech into a new company: Pixel Qi. A fabless display firm focused on low-power, sunlight-readable screens for mobile devices. While typical tablet screens ate up 90% of a device’s power, Pixel Qi’s designs slashed consumption by 10x. Her next move took her into the heart of Silicon Valley innovation: Google X. There, she reported directly to Sergey Brin. She led programs across Google’s consumer electronics and display hardware divisions, including Google Glass. By 2015, she had joined Facebook/Oculus as Executive Director of Engineering. She spearheaded the move from OLED to liquid crystal systems in Oculus Quest 2. Invented foveated AR vision with a 180° field of view. And built Facebook’s first brain-computer interface team. But, in 2016, she decided to start over. She founded Openwater, a medical tech startup whose mission is to replace the functionality of MRI machines with wearable, low-cost electronics—and use them to treat disease, not just diagnose it. Her devices use infrared holography and low-intensity focused ultrasound. And in preclinical and clinical testing, Openwater’s tech achieved near 50% remission rates in patients with severe depression, through ultrasound harmonics that calmed overfiring neurons. All 68 of Openwater’s patents? Free to use. All hardware schematics? Creative Commons Share-Alike 4.0. All software? AGPL open source. In 2024, she raised $54M to scale Openwater’s technology platform into a fully open medical system that could slash the cost of diagnostics and care around the world. Mary Lou has won every award in sight: TIME 100 most influential people, CNN Top 10 Thinkers, Forbes Top 50 Women in Tech, and more. She’s not in the business of moonshots. She’s in the business of moon landings. 💡 In 2025, I’m sharing 365 stories of women entrepreneurs in 365 days. Follow Justine Juillard for daily #femalefounder spotlights.
