XBOW
XBOW@Xbow·
Technology proven ✅ Market fit proven ✅ Now it’s time to SCALE 🏹🚀 Together with @dfjgrowth and @northzoneVC, we just announced a $120M funding round, valuing XBOW at over $1B. Our Autonomous Hacker was trained by elite human security experts. In 2025, we proved it can safely and effectively operate in real production environments. Today, over 100 customers worldwide already trust XBOW to protect their most critical assets. As AI allows attackers to move faster, defenders need the same continuous speed and capabilities. This milestone allows us to bring autonomous offensive security to the entire industry at the exact moment it’s needed most. Read more: bit.ly/4lA033O

Our first meeting with Yevgeny Dibrov and Nadir Izrael was in @ArmisSecurity's modest Palo Alto office back in 2018. We were immediately struck by their ambitious vision and the product's early breakout growth. DFJ Growth officially partnered with Armis in early 2020, and it’s been an epic run ever since. It has been phenomenal to watch the team scale from an emerging leader into a global powerhouse, protecting everything from IT to critical OT infrastructure. Armis has gone well beyond their initial product by defining the Cyber Exposure Management category. Their $7.75 billion acquisition by @ServiceNow is a well-deserved validation of the relentless execution and culture this team has built over the past decade. So proud to see Armis reach this milestone. A massive congrats to the entire team!! 🚀
Armis@ArmisSecurity

📢 MAJOR ANNOUNCEMENT 📢 We are excited to announce today plans for Armis to become part of @ServiceNow, the AI control tower for business reinvention. At Armis we are focused on building a generational cybersecurity business; with this mission in mind, partnering with ServiceNow will allow us to expand on their security workflow strength and accelerate our mission to deliver Exposure Management and Security as well as Cyber Physical System Security in an accelerated fashion. With its advanced AI-driven software for workflow process and automation, becoming part of ServiceNow is an exciting next step that will expand the security innovation Armis delivers to our diverse customers globally. Our synergies with ServiceNow enable us to connect real-time asset discovery, threat intelligence, and risk prioritization with automated remediation and response workflows - driving the very best security outcomes for our customers through: ➡️ Stopping attacks before they happen by leveraging Armis Exposure Management and ServiceNow response workflows. ➡️ Protecting the most important physical environments and critical infrastructure, while allowing customers to focus on running their business. ➡️ Accelerated innovation and more value by connecting market leading ServiceNow AI Platform with Armis Exposure Management and CPS solutions.

Every era of computing is defined by breakthroughs that simplify layers of complexity. We believe Modular is building this for AI, freeing developers from hardware lock-in so they can focus on creating, not configuring. Proud to partner with @clattner_llvm, @iamtimdavis, and the @Modular team on their $250M Series C!

My startup, @positron_ai just raised $51.6M Series A to rebuild the infrastructure powering AI inference and bring Superintelligence to everyone. Led by Valor Equity Partners (@valorep) , Atreides Management (@Atreidesmgmt) , and DFJ Growth (@dfjgrowth) —the same teams behind SpaceX, Tesla, xAI, and other companies pushing compute to its physical and economic limits. Why inference? Because as AI moves from research into production, the real bottleneck isn’t training—it’s deploying transformer models at scale. GPUs were built for flexibility, not predictable workloads. That mismatch means wasted bandwidth, poor density, and massive power costs. So at Positron, we built silicon specifically optimized for inference: •>90% memory bandwidth utilization (GPUs typically ~30%) •Multi-model hosting per card (higher density, lower power) •Zero code changes — drop in compatability with the HuggingFace Transformers ecosystem. 
U.S.-made silicon, stable supply chain, geopolitically resilient We’re already shipping and running in production environments today. Here’s what we’ve built, and link to our WSJ coverage and press release in the follow up reply ↓

AI is rapidly changing how software gets built — but security products haven't kept up. That’s why we’re so excited to announced @dfjgrowth is leading the $93M Series B in @EndorLabs. Endor is rethinking AppSec for the AI era, giving devs a smarter way to ship secure code without drowning in false positives or dependency chaos. Their platform cuts 92% of alerts and helps teams fix real issues 6x faster — and now they’re using AI to review AI-generated code before it ever hits production. Huge shoutout to founders @varun__badhwar and @dstiliadis — the team is building something truly special, and we're thrilled to partner on the journey ahead!

Join xAI. Play in the big league 🚀
Elon Musk@elonmusk

@xAI has acquired @X in an all-stock transaction. The combination values xAI at $80 billion and X at $33 billion ($45B less $12B debt). Since its founding two years ago, xAI has rapidly become one of the leading AI labs in the world, building models and data centers at unprecedented speed and scale. X is the digital town square where more than 600M active users go to find the real-time source of ground truth and, in the last two years, has been transformed into one of the most efficient companies in the world, positioning it to deliver scalable future growth. xAI and X’s futures are intertwined. Today, we officially take the step to combine the data, models, compute, distribution and talent. This combination will unlock immense potential by blending xAI’s advanced AI capability and expertise with X’s massive reach. The combined company will deliver smarter, more meaningful experiences to billions of people while staying true to our core mission of seeking truth and advancing knowledge. This will allow us to build a platform that doesn’t just reflect the world but actively accelerates human progress. I would like to recognize the hardcore dedication of everyone at xAI and X that has brought us to this point. This is just the beginning. Thank you for your continued partnership and support.
