@amorriscode @bcherny Love Claude Desktop and use it as my primary interface. The biggest feature gap is not being able to monitor long-running tasks from my phone. Would love to see Desktop sessions register with the Remote Control API the same way CLI sessions do. #issuecomment-4249456077" target="_blank" rel="nofollow noopener">github.com/anthropics/cla…

Today we're launching a rebuilt version of Claude Code on desktop. The app has been redesigned for the ground up to make it easier than ever to parallelize work with Claude. I haven't opened an IDE or terminal in weeks. Excited for you all to give it a shot!

@MarikHazan @ycombinator Also, I think the recognition that messy industries can be good attack vectors is a good one. I also think you need an experienced industry veteran to help your startup navigate that industry.

We just rebuilt every startup in @ycombinator's latest demo day batch. Here's what our agentic "founders" pulled off and what it means for the future of startups. Fully useable products at the bottom of the thread below 🤖🧨

Incredible really. I've been feeling this for awhile, tere are two startup camps. One camp is "this is the best time ever to start a new company, there's no friction to creating whatever you can imagine." The other camp is, "why in the hell would I start a business that can be replicated in a day."

The best thinking happens when you stop thinking. But you can’t force it. Some of my clearest insights have arrived when my mind was quiet. Not grinding through a problem. Not “trying to think.” Just… still. I’ve learned there’s a place beyond active thought — where the noise drops, the pressure lifts, and something deeper comes through. One of my favorite ways to get there? Sitting by a campfire. Soft-eyed, staring near the base of the flame. At some point, the edges blur. The mind stops grasping. And then—when I least expect it—clarity arrives. You might find it in different ways: A long beach walk. The moments after a hard workout. An hour in nature. Meditation. Or just sitting still and observing. We all have access to it. We just rarely give ourselves permission to go there. Sometimes the most important thing isn’t to do more. It’s to be more. What are some of your favorite ways to drop in and just be? – Lex, your CEO coach 📌 P.S. Some breakthroughs come from action. Others arrive in the space you leave open for them.

📌 P.S. The book Atomic Habits by James Clear is more popular but it's actually based largely on the work of Dr. BJ Fogg, a behavior scientist and the founder of the Behavior Design Lab at Stanford University. The core idea is that the easier and more incremental you can make a new habit, the better. Why? Because inertia in all systems is a real thing. Start small and build up over time. tinyhabits.com

📌 P.S. Here's another exercise that complements the work in Discover Your Genius Zone. It's called Your Vision and Action Plan and it creates the framework to align your short-range habits and goals with your longer range vision. organizationalphysics.com/your-vision-an…

I’ve developed the habit of… refining my habits. And it’s made all the difference. For the past five years, I’ve been running a simple personal system: → Each morning, I journal an “energy scan” — what gave me energy yesterday, what drained it. → Each Sunday, I review my habits and goals, reset, and recommit for the week. → Each month, I do a Habit Review: score progress, refine, and set new ones. The key isn’t perfection. It’s progress over time. And progress comes from clarity. Most of us are carrying habits we didn’t actually choose. We’ve inherited them from our environment or from our own past identity. But if you want to be free, then your habits must align with what really matters to you now. That’s why I revisit mine daily, weekly, and monthly. Not to be “disciplined” for its own sake. But to stay aligned — and to keep subtracting what no longer fits.

📌 P.S. Most breakdowns aren’t about talent or effort — they’re about a system that no longer matches the business it’s meant to serve.

The magic of your early team won’t last forever. But it’s not always clear why it’s breaking down. In the early climb to $30M, things just worked. The right people. The right rhythm. The right instincts. But in the Nail It phase, that chemistry starts to change. Suddenly: Cross-functional friction creeps in. Decisions take longer than they should. What used to be clean execution now feels like molasses. And here’s the hard part — you can’t tell if it’s: → A leadership problem → A few wrong people in key seats → Or the growing complexity of the business itself The truth? It’s often all three — and they’re symptoms of the same root cause: The structure that once amplified your team is now holding them back. I work with $30M–$100M CEOs who’ve built real momentum — but can feel the team slowing under the weight of outdated structure. This isn’t about “fixing people.” It’s about diagnosing the system so the right leaders can make the right calls, at the right speed — without the organization grinding against itself. When the team is no longer working as well as it used to, don’t just swap players. Redesign the game they’re playing. Structure first. Scale second.

📌 P.S. I’ve learned the hardest battles are often with yourself — and the greatest wins come when you stop fighting who you’ve become.

The things that stroked my ego stopped feeding my soul. That’s when I knew I had to rewrite my code. From an early age, I designed my life to be an entrepreneur and CEO. I hit that target. More than once. But in my late thirties, something shifted. The very role I had been building toward for decades was draining me. Not because I couldn’t do it — but because it no longer aligned with how I was wired. One of the principles in Organizational Physics is simple: Maximize energy-gaining activities by minimizing energy-draining ones. So I turned that lens on my own life. And I saw the truth: running a company as CEO was now an energy drain. Coaching leaders — that lit me up. I also recognized a shift in my PSIU style. From PsIu — the driver-innovator CEO profile — to psIU — the patient, unifying guide. For five years I wrestled with that truth. My ego still liked the CEO title and comp. My soul wanted something else. Eventually, I made the commitment: I’d stop trying to be both CEO and coach. I’d go all-in on what gave me energy and fit my evolved style. It was one of the hardest transitions of my life. And absolutely worth it. Sometimes growth means letting go of the version of yourself you once fought to become. Not because you failed — but because you evolved. Curious what your leadership style really is?

The biggest risk to a CEO isn’t failure. It’s building a company you don’t want to lead. The revenue grows. The team expands. The company looks great. But the CEO is exhausted, resentful, and wondering how they lost the thing they loved. Scaling without self-awareness is like planting a tree in the wrong soil — growth is possible, but it won’t last. When you know your leadership wiring, you can design a company that fits you… and watch it thrive without draining you. You built this business to serve your life — not the other way around.

Even a strong oak will struggle in the wrong environment. Create the right conditions, and everything will flourish.

So many leaders try to fix people. The best ones? They fix structure. What looks like “underperformance” is often just energy in the wrong role. Over the years, I’ve stopped diagnosing people. Instead, I look at how energy flows across individuals and teams. That’s where PSIU comes in. Every team expresses four forces: → Producing — drives execution and momentum → Stabilizing — brings order and process → Innovating — pushes for change and vision → Unifying — builds trust and cohesion Each style has strengths. Each has stress responses. And every company needs all four — especially as it scales. But here’s the catch: When these energies are out of balance, you’ll feel it. Slow decisions. Internal drag. Recurring friction between leaders. PSIU gives you a structural lens to: → Spot energy gaps → Hire for balance, not similarity → Align leadership styles with lifecycle stage → Build a team that executes and evolves This isn’t about personality. It’s about designing your org to do what it was built for — without friction at every turn. If your structure isn’t aligned, even your best people will underdeliver. If it is? You’ll stop managing symptoms… and start scaling with clarity. Want to discover your dominant force?

Growth is up. But execution feels slower than ever. I’m on a mission to get my life’s work into the hands of the right CEOs — before complexity stalls what they’ve worked so hard to build. For the past decade, I’ve worked behind the scenes with expansion-stage founders — usually after they’ve already crossed $30M. Not as a traditional business coach. As a structural advisor. Helping them break through the ceiling of complexity that shows up once you’ve scaled… and everything starts to wobble. It’s not a tactic issue. It’s not a “people” issue. It’s structural. And I’ve spent the last 15 years building systems that solve exactly that — using first principles and a framework I call Organizational Physics. The results have changed lives. But lately, they’ve been buried under algorithms, noise, and outdated traffic channels. That ends now. Here’s what CEOs have said: “In one year operating with Organizational Physics, we drove a CAGR of 149% and improved revenue per employee of 187%.” — Jason B. “Lex transformed our structure and team alignment, enabling us to achieve a $2M positive swing in one year and build a stronger leadership team.” — Tami S. “Lex’s framework helped us grow revenue by 60% in nine months and accelerate decision‑making. He delivered exactly what we needed to scale faster.” — Issac O. If you're scaling fast and starting to feel friction you can’t quite name — it’s not all your fault. You’re leading a system that wasn’t designed for where you’re going. The answer isn’t to hire faster or work harder. It’s to redesign the ship you’re sailing. That’s what I help with. Not surface-level fixes. But a deep structural transformation — so your strategy, structure, and leadership model finally align. I’m going to be sharing the same systems I use with $100M+ CEOs to help them simplify, scale, and build the business they actually want to lead. If that’s the trajectory you’re on — follow along. This is just the beginning. Curious what your leadership style really is? Take the free PSIU Assessment here (a free $25 value): organizationalphysics.com/psiu/free-test/ – Lex, your CEO coach P.S. It’s easy to mistake momentum for alignment — until the system breaks. I’ve learned to fix it before it does.

Don’t sacrifice resiliency for stability. Just sayin!
