    The RSAC Conference had 54+ AI SOC vendors on the floor this year, all competing in the same cyber-neon aesthetic. We decided to build a 1950s American diner instead. Chrome counter, red pendant lamps, checkered floors, Wagyu sliders, a robot named Droppert greeting guests by name, and a laminated diner menu that doubled as the product brochure. Last night it took 1st place at the Cybersecurity Marketing Society's Beautiful Booth Awards. 🏆 I couldn’t have done it without my rockstar team. Our Dropzone AI marketing team took on 54+ competitors and won with end-to-end support from Chantel Pszenny, Kim Fischer and Cubic Squared, who ran point from concept through on-site activation into post-show amplification. The insight isn't "do something weird." In a category where every booth opens with the same threat graph, the fastest way to be remembered is to build an experience that doesn't feel like cybersecurity at all. Human scale wins attention when the category is selling machine scale. Thanks to the Cybersecurity Marketing Society, especially to Gianna Whitver, Maria Velasquez and the anonymous judges. To everyone who stopped by, tried a slider, or met Droppert: see you at Black Hat! You won’t want to miss the Dropzone AI Diner v2, we have even more things cooking. 🍳 See all the winning booths here: https://lnkd.in/dRY2-mKG #CybersecurityMarketing #RSAC2026 #GrowthMarketing #B2BMarketing

    "That loser premise makes no sense to me." - Jensen, stealing the mic 🎤 Last week was all Mythos. This week, everyone else wanted a turn – and most of them were auditioning for Wall Street. 📄 OpenAI's new CRO leaked a four-page memo ripping Anthropic on run rate ($8B overstated, allegedly), Microsoft, and platform strategy 🧠 Claude Opus 4.7 retakes the coding lead 🛡️ GPT-5.4-Cyber opens cyber access to thousands of defenders vs. Anthropic's 50-org Glasswing lockdown 🧬 GPT-Rosalind for life sciences lands with Amgen, Moderna, Allen Institute 🛰️ Amazon buys Globalstar for $11.6B (Apple now has a Starlink competitor) ⚡ Maine bans data centers (short terrestrial compute, long orbital) 🚕 Uber reverses course, commits $10B+ to AV ownership 🧮 GPT-5.4 Pro cracks a 60-year-old Erdős problem in 80 minutes (Terence Tao says it's legit) The IPO subtext was everywhere. Dresser's memo, Narasimhan on the Anthropic board, the cyber access debate – all of it feels like a dress rehearsal for an S-1 audience. Public markets are harsher judges than private ones have been. The question of 2026 is whether consumer dominance converts to nine-figure enterprise ARR. We're about to watch both companies answer it in front of an audience that has zero interest in Twitter accounting arguments. Full breakdown 👇

    Phishing is STILL one of the number one attack vectors for bad actors. The numbers don't lie: → Over 90% of cyberattacks begin with phishing AI is making that even worse. Over 82% of phishing emails detected in a recent 6-month window used AI (a 53% year-on-year jump). And since ChatGPT launched, phishing email volume has risen by over 1,265%. Phishing emails can be indistinguishable from real ones. How are users supposed to know what to trust? Sublime Security is changing that. Instead of static filters that bad actors have learned to bypass, their platform deploys AI agents that detect, adapt, and respond to new threats within in hours. The result? → AI agents that stop attacks before they reach users → Threats detected and responded to in hours → Full transparency into every decision AI is being used to attack. It should also be used to defend. If you want to learn more, check out: 🔗 https://lnkd.in/g4kBEREj P.S. have you ever been phished? 🎣 #ad #DecibelPartner Decibel Partners Sublime Security

    At this point, every software company should be asking itself if it actually deserves to exist in the AI era. Another way of thinking about it is: Is the software you're building above or below the "Token Threshold"? The Token Threshold is the point at which the cost to build a capability from scratch exceeds the cost to buy it, measured in inference tokens. Every software product sits either above or below this line. Below it, agents build. Above it, agents buy. If you play the current trajectory forward-and more enterprises complete their agentic transformation (we’re all running Cowork on our desktops now, aren’t we?) - the real influencer of a purchasing decision might eventually not be a human. Therefore, what it means to be a software vendor in the AI era might also change. In our current model, humans evaluate software tools, sit through demos, navigate procurement, and ultimately decide whether to buy software or build it themselves. Everything in software - pricing, content, sales cycles, product strategy all the way down to fancy steak dinners - exists to push that decision toward buying. And it worked because building software used to be expensive and time-consuming. Most teams didn’t want to take on that burden unless they absolutely had to. But what happens if the buyer eventually is just an agent? Build vs. buy might just run through a code sandbox (shout-out E2B!) and a cost benefit analysis of burning tokens or spending $ from a budget. So far the strategy has largely been out running / out engineering general purpose agents but the question is really how long that will last. Reframing this, so that software vendors can go from defense to offense means asking, how do we build something that is hard to replicate but still very useful for the agent. In a way, a lot of software was built on borrowed time - on human inertia holding longer than it should. AI is just calling that bluff... More on my thoughts on the Token Threshold in the latest Founder Catalyst edition.

    Microsoft just published a case study on how Veris AI and Lume Security built a self-improving agent on Microsoft Azure Foundry. One of the hardest problems in enterprise AI isn't getting an agent to work in a demo. It's making it improve safely in production, where long-tail edge cases are rare, labeled data is scarce, and you can't iterate on live users. Lume's security agent was misclassifying ticket workflow states at triage, sending access requests down the wrong downstream path. We dropped it into a Veris Simulation Sandbox, reconstructed the failure from production traces, expanded it into a family of realistic scenario variants, and ran the full optimization loop: automated rubric generation, trajectory grading, and prompt refinement. The result: over 40% improvement on the failure mode, with zero regression on previously correct behavior. No labeled dataset. No manual prompt guessing. Just your production failures, simulated, scored, and fixed. Get in touch to gain access to our beta platform. Link in comments.

    Huge congratulations to Jonathan Cran and the Mallory team for launching their AI-native threat intelligence product into GA today! In the agentic era, attackers no longer operate at human speed. They use AI to discover vulnerabilities, chain exploits, and execute attacks faster than defenders can reason about them. Meanwhile, most threat intelligence platforms were built for a different time, one defined by manual and human analysis of feeds, dashboards, and reports. That model is breaking. Security teams don’t have a data problem anymore; they have a context and reasoning problem. They’re flooded with signals but lack clear answers to what actually matters: what’s exploitable, are we at risk, and what should we fix right now? Mallory flips this paradigm. It ingests global threat data, maps it to an organization’s real environment, and uses AI to generate prioritized, evidence-based answers, not more alerts, but actionable intelligence. Jonathan Cran has spent his entire life working on this problem, first as a young pen tester at Rapid7, then as Head of Research of Kenna Security (acq. by Cisco) and CPO of Bugcrowd and most recently at Mandiant (part of Google Cloud), building what became Google's Global Threat Intelligence product. We, at Decibel Partners, are incredibly excited to partner with Jcran on this journey and can't wait to see what he and the team build next! Read more in our founder Q&A in the comments below. PS: They are hiring!

    Mallory is now GA! Today we're launching our AI-native threat intelligence platform built for one question: "Are we affected?" We track thousands of sources, contextualize to your environment, and make investigation easy, whether you're running a three-person team or a thirty-person SOC. We're also announcing our seed funding from Decibel Partners, as well as an incredible team of angels - enabling our team to grow and explore the edges of what's possible when you harness the frontier models for security operations. More on why we built it and what's next here: https://lnkd.in/gdeeJw6M
