Mike Krieger shared thisSonnet 4.6 just launched! For most people, this should be your new default model. Computer use is the headline. We've been building toward this for 16 months, and Sonnet 4.6 is by far our strongest model for it. Early users are seeing near-human performance on tasks like navigating complex spreadsheets and multi-step web forms. And Sonnet 4.6 approaches Opus-level intelligence at the same price as Sonnet 4.5. Also shipping today: MCP connectors in Claude in Excel (S&P Global, LSEG, FactSet, PitchBook, Moody's, Daloopa), a 1M token context window in beta on the API, and web search and fetch tools that are now more accurate and token-efficient. We can’t wait to see what you build! https://lnkd.in/gA7NhK8S

Mike Krieger shared thisWe’re hiring PMs at Anthropic! I recently joined our Labs team at Anthropic to be hands-on at the frontier. We’re building product categories that don’t exist yet, on top of technology that’s advancing rapidly. The PM role is part scout, part builder. You’re identifying what’s worth pursuing, prototyping yourself, and iterating quickly with your team to find product-market fit. If you have real AI experience and have founded something, or have been the first PM on something ambitious, then this may be the role for you. Apply below.

Mike Krieger shared thisThe team just launched Claude Opus 4.6. It can take a development project from architecture to deployment in hours instead of days. It navigates business tools with near-human reliability. And it can pull together regulatory filings, market data, and internal sources into analysis that would take an analyst days of tedious time to produce. In their early testing with Opus 4.6, Rakuten autonomously closed and assigned issues across a 50-person organization, handling both product and organizational decisions and knowing when to escalate. At Harvey, it hit the highest BigLaw Bench score of any Claude model — 90.2%. We have a ton more shipping today: Agent teams in Claude Code, context compaction, a 1M token context window on the API alongside the model. And for knowledge work, all new Claude in PowerPoint and an upgrade to Claude in Excel.Mike Krieger shared thisIntroducing Claude Opus 4.6. Our smartest model got an upgrade. Claude Opus 4.6 plans more carefully, sustains agentic tasks for longer, operates reliably in massive codebases, and catches its own mistakes. And, in a first for our Opus-class models, Opus 4.6 features a 1M token context window in beta. Opus 4.6 can apply its improved abilities to a range of everyday work tasks: running financial analyses, doing research, and using and creating documents, spreadsheets, and presentations. Within Cowork, where Claude can multitask autonomously, Opus 4.6 can put all these skills to work on your behalf. We're also shipping new features and updates: In Claude Code, you can now spin up agent teams that coordinate autonomously. On our API, adaptive thinking and effort controls let Claude calibrate how deeply to reason, while context compaction keeps long-running tasks from hitting walls. Claude in Excel now handles long-running and harder tasks with improved performance. And with Claude in PowerPoint (now in research preview), Claude builds, edits, and iterates on decks in real time. Available today on claude.ai, our API, and all major cloud platforms. Read more: https://lnkd.in/eA-F99xz

Mike Krieger shared thisBack in September we brought Claude into Xcode. Today that goes a big step further. Xcode 26.3 brings the same harness that powers Claude Code to Apple devs. Instead of responding to one request at a time, devs can now take a goal, break it down, explore your project structure, search Apple's docs, and iterate on its own. The visual verification loop is really cool. Claude can capture Xcode Previews to see what it's building, spot issues, and fix them without developer intervention. If you’re building SwiftUI interfaces, this is a huge shift in how fast you can ship. Read more on our blog: https://lnkd.in/gC9VkCn2

Mike Krieger posted thisCNBC's new documentary details Anthropic's rise as the top enterprise AI provider, but underneath it are the builders who choose Claude because they trust it for real work, like coding, reasoning, and building amazing products.That's what enterprises actually need. And it's what we optimize for every day when building Claude. Thanks MacKenzie Sigalos for telling our story!

Mike Krieger shared thisThere’s never been a better time to be a builder — Opus 4.5 & Claude Code keep surprising me in the quality and completeness of the products they can create. So I’m doing exactly that — putting my product founder hat back on and joining our Labs team to be hands-on at the frontier, building products that channel AI toward solving the world's hardest problems. Excited to pass the baton to Ami Vora as she leads the product team in scaling Claude.Mike Krieger shared thisWe’re expanding Labs—the team behind Claude Code, MCP, and Cowork—and hiring builders who want to tinker at the frontier of Claude’s capabilities.

Mike Krieger reacted on thisMike Krieger reacted on thisI stepped back from my $200M+ rev/year startup and joined Anthropic to help build safe AGI. Here's my resignation letter and my 9-step transition process so my company could continue to grow 50%+ YoY after my exit: I’m sharing this openly as there are many guides on starting companies, but none on resigning and transitioning well. As AI continues to accelerate and consume SaaS, many unicorn founders have reached out asking about transitioning best practices. They don't know how to set the company up for continued success and leave while preserving the legacy they've built. So here's what I learned after spending 9 months preparing my exit: Step 1: Write down your story before you tell anyone I spent 3 weeks documenting my purpose, mission and what I accomplished during my tenure. That document became my north star Step 2: Talk to your co-founder privately That Christmas call with Hussein was one of the hardest conversations I've ever had. Make it an honest heart-to-heart conversation. Share openly and don't hold back. Align on the successor and the timeline before anyone else knows. Step 3: Talk to board members 1:1 and not in a group In group settings, board members often perform for one another, whereas individually, they are honest and collaborative. I spent months on these conversations, so by the official board meeting, every member was aligned. Step 4: Hold the official board meeting This should happen after your successor is finalized with a clear timeline and next steps. Step 5: Email investors with your narrative and legacy attached Share a complete narrative, specific accomplishments with numbers, and a succession plan. Own your story. Step 6: Talk to C-suite and key employees 1:1 before the all-hands I scheduled 30-minute 1:1s with 15+ people over two days. It was exhausting, but the most meaningful conversations of the transition. Step 7: Make the company-wide announcement Then hold office hours and show up for the questions. Step 8: Use the window before your last day You can't get fired, and this is the only time you have full founder authority with zero consequences. Push bold initiatives, set up easy wins for your successor's first 90 days, and document everything. Step 9: Make the public post count My LinkedIn post got 100k+ impressions, hundreds of comments, and dozens of opportunity DMs. I told the story with specific numbers, celebrated the team by name, and ended with a clear CTA. Remember that your transition only succeeds if the company thrives after you leave. If you are considering a transition to an AI lab or just thinking of an exit, start planning now instead of waiting until the last moment. Subscribe to my Substack for the complete resignation letter, the detailed 9-step process with specific timelines for each phase, the conversations I had with my co-founder, board members, and investors, and every hard-earned lesson from my exit. 👇 Link in first comment

You can always build something you’ve already sold. But you can’t always sell something you’ve already built. When I was at IDEO, I watched David Kelley say “yes” to client projects that sounded impossible - six-week timelines, half the budget, specs that defied physics. He’d nod, smile, and say, “We can make that happen.” Then we’d start sketching concepts and building prototypes in the shop, and before long, we had figured out how. Kelley knew it was easier to build toward a committed outcome than to sell an idea no one had asked for. I still see this play out with founders. Many fall in love with the thing they’ve already built - the clever piece of tech, the whiz-bang widget - and then realize nobody’s asking for it. The best founders uncover hidden demand and build products that bring to light opportunities that would otherwise remain unseen. That order matters. Start with the problem or opportunity, then design the solution.

This woman built tech that can spot bipolar episodes, detect postpartum depression, and keep her diabetic son alive. Vivienne Ming is a theoretical neuroscientist, a serial entrepreneur, and a self-proclaimed “mad scientist.” Her obsession? Maximizing human potential. Vivienne was born Evan Campbell Smith. By her early twenties, she had dropped out of college, fallen into depression, and was contemplating suicide. Then she made a decision: if she was going to keep living, she was going to do something substantial. She flipped a coin between economics and cognitive science. It landed on cognitive science. She went back to UC San Diego, earned a degree in cognitive neuroscience, then completed a PhD in psychology and theoretical neuroscience at Carnegie Mellon. While in grad school, she met Norma, a fellow PhD student. They fell in love. And one night, Vivienne told her the truth. “My secret is that I wish I were a woman.” Norma didn’t run. She listened. Vivienne underwent hormone therapy after conceiving their first child, Baxter, and completed gender confirmation surgery in 2008. They later had a second child, Thalia. Over the next two decades, Vivienne launched six startups, and served as chief scientist at two others. She invented AI systems that could: - Predict manic episodes in bipolar patients - Reunite refugee orphans with surviving relatives - Help autistic children learn to read facial expressions - Manage her son’s diabetes in real-time - Identify and mitigate bias in hiring - Improve cognitive recovery in TBI and dementia patients - Assess student creativity and emotional intelligence In 2011, she co-founded Socos Labs, her fifth company, a “mad science incubator” focused on the intersection of neuroscience, AI, education, and human development. Then she built The Human Trust, a nonprofit data trust that works on complex social challenges: disability, economic exclusion, algorithmic justice… She also co-founded Dionysus Health, where she helped create the world’s first biological test for postpartum depression, using AI and epigenetics to identify risk before symptoms appear. Throughout it all, her central thesis never changed. AI is not the end of the world. It’s not salvation either. It’s a tool, it’s only as useful as the humans who wield it. The real danger, she says, is that we’ll use AI to do just enough. That we’ll automate away our creativity. Flatten our curiosity. Become passive operators of tools we don’t fully understand. When writing her latest book, Robot-Proof, she fed every chapter into Gemini. But not to edit. “I tell it: You’re my nemesis. Tear this apart. Tell me where I’m wrong. Then I run it again: Now you’re a bored reader. Show me where you got lost.” Her work has earned her a spot on the BBC 100 Women list, Inc. Magazine’s 10 Women to Watch in Tech, and more than a dozen research and innovation awards. 💡 Follow Justine Juillard for daily #femalefounder spotlights

Wisdom Ventures • 4K followers
Three years ago, we launched Wisdom Ventures with a clear intention to support founders building at the intersection of well-being, human connection, and transformative tech. Since then, we’ve made 37 investments from our oversubscribed "minimum viable" $10M Fund I, backing early-stage companies in physical and mental wellbeing, women’s health, ethical AI, and human connection-centered innovation. We’ve always known we are on to something—what we didn’t expect was how quickly the data would back it up. Recent industry benchmarks show that most 2022-vintage emerging funds are experiencing the usual J-curve dip. In contrast, Wisdom Ventures is showing strong early performance: 📈 Net IRR (internal rate of return): >10% 📊 MOIC (multiple on invested capital): ~2x* ⏰ Median investment age: 18 months 💥 ....and # of our companies have a diverse founder by gender, race, or sexual orientation: 75% As we get ready to make our 38th and final investment out of Fund I and start deploying out of our significantly larger Fund II (first close May 1st), we’re filled with gratitude—for our founders, our LPs, our early supporters, our early believers, and this growing movement toward a more conscious, connected future, fueled by innovation from the ❤️ *Based on most current reports **Not in photo: Our fantastic operating partner, Zoe Rogers #WisdomVentures #ImpactInvesting #ConsciousTech #Wellbeing #AIForGood #FutureOfWork #VentureCapital

There is so much magic for scientists locked away in LLMs. But unlocking it requires a rare blend of scientific and engineering expertise. That’s why I’m thrilled that Nicholas Larus-Stone and Sphinx Bio are joining Benchling. I’ve gotten to know Nicholas over the last few months. We share a vision for what AI agents can do for scientists – and an obsession with turning that potential into real, everyday value. Together, we’re building agents that automate toil and answer complex questions. See what we’re building: https://lnkd.in/gtDHZpnt

Dewey Labs • 2K followers
My first reaction to the Anthropic safety pledge change this week? Sh*t. As an AI-skeptical founder who's spent the last few years building an AI company with Dewey Labs, Anthropic's original pledge – to pause scaling and deployment if safety measures couldn't keep pace – felt like a rare moment of our better angels winning. And these headlines felt depressing. But then I re-read the stories, and dug a bit deeper into the original sources from Anthropic. And I think the media has missed a much more nuanced story in the service of a good headline. The old pledge put Anthropic's safety researchers in a trap. Raise serious concerns about a model's risks, and you might freeze the company's development pipeline – with consequences for competitive position, for stock value, for careers. Stay quiet, and the industry loses critical information about where real dangers are emerging. There's no good answer there. And as Anthropic's own assessment admits, capability thresholds turned out to be far more ambiguous than they'd hoped. Clean go/no-go calls on genuinely murky definitions aren't just hard. They distort how research gets done. The new structure largely eliminates that conflict. Safety teams can now push hard, publish often, and do it without holding a sword over the company's head. Anthropic committed to Risk Reports every 3–6 months – graded publicly against specific, stated goals. Holden Karnofsky, who helped design this change and by his own account pushed for it for over a year, doesn't describe it as a capitulation. He calls the old approach a design flaw. When you find a flaw, you update it, even if it doesn’t play well in the public eye. I get it – this can still read as competitive pressure winning out over principle. There are real business incentives at play and I'm not naive about that. The political climate around AI regulation has also shifted significantly, which Anthropic doesn't try to hide. But a single company committing to pause while its competitors keep building doesn't make AI safer. It just makes the safety-conscious lab smaller and less influential – and puts the pace of development in the hands of whoever has the fewest guardrails. Anthropic isn't wrong about this. And they're not alone: a RAND report they cite directly says certain security standards (designed to defend against state-level attacks) are "currently not possible" for any single company. Pledging to achieve them unilaterally was never going to work. Is it perfect? No. Nothing in this space is, especially at the speed we're moving. But trading a symbolic pledge for a more functional accountability structure seems like the right direction – even if it's a harder case to make in a headline.

The most transformative growth doesn't happen in isolation—it emerges from ecosystems. Through my work building ecosystems like Energize Colorado, Elevate Quantum, State-funded advanced industry ecosystems (Space, Climate, and Water), and a current early stage project on a Creative Hub (ecosystem) for film and music, I've seen how both innovation ecosystems (connecting startups, corporations, universities, investors) and community ecosystems (building networks of trust and shared purpose) create greater value when a diverse group of partners collaborate. Whether building an innovation or community ecosystem, the same principles drive success: -Diversity of participants brings complementary skills and fresh perspectives. - Flow of resources (ideas, funding, mentorship, networks, social capital) accelerates progress for everyone. - Shared purpose aligns individual success with collective impact. The magic happens when we shift from "what can I achieve alone?" to "what can we accomplish together?"

This is exactly the kind of structural change I've been waiting to see. For decades, I watched promising technologies stall between lab and fleet. Not because they didn't work, but because our innovation ecosystem was fragmented, slow, and confusing to navigate. Putting DIU, SCO, DARPA, OSC, and CDAO under one CTO umbrella does three things right: • Creates one front door for innovators instead of a maze • Forces accountability on transition decisions • Signals speed to industry partners who've been burned before I've sat through enough Pentagon reorganizations to stay skeptical. But the people behind this one are serious. And Owen West at DIU brings something rare: combat experience AND private capital background. He's lived on both sides of the divide that kills most defense innovation. https://lnkd.in/dQbdepA2
