Every $1 invested in UX returns $100. That's a 9,900% ROI. There is no other investment in business with that return profile. None.
I don't really understand devs who jump back and forth between LLM providers. Claude, Codex, Claude, Gemini, back to Codex, then Claude. What marginal improvement can be worth the massive context shift every single time? Pick one and build. You won't have...

Microsoft’s AI chief says AI will automate most white-collar work in 18 months. He claims AI will handle law, accounting, marketing, and coding at human level. Yet reports show only small productivity gains, and one study found developers took 20% longer with...

When you say “not now” instead of “no”… …you are avoiding making a decision. That’s good, if waiting means you can make a better decision (e.g. more data, more options to pick from). That’s bad, if you’re just non-committal. Cross things off the list.
I want to be crystal clear: the advice I give on LinkedIn is NOT for founders who think they're creating unicorns, decacorns, or the next Anthropic. If you believe you're building a unicorn or decacorn and you're sitting here reading...
A “pivot,” as opposed to “throwing shit at the wall,” means that you identified what parts of the strategy have been reinforced with new evidence (the foot that remains planted) and which have been invalidated, and replaced by what precisely...
Customer segmentation drives growth. Many businesses ignore it and waste budget on broad marketing. Group customers by behavior, survey feedback, and purchase history. When campaigns match each segment and product decisions follow real data, sales rise. If all customers are treated the same, how...

"Build something people want." Focus on solving real problems for your customers. It's best when founders have actually lived the problem.
Going from 0-100M in 5 years used to be called hypergrowth. In the AI era, that’s SLOW. The new standard is going from 0-100M in 12 months or less. I call this WARP speed. Companies that have scaled at WARP...
1.5 years ago, I spent an entire month designing Theanna from idea to... design. (just design) Last night, I used Claude Code to design and implement a front end for a brand new feature, generate Linear tickets, and assigned to a...
From now on, hype-centric splashy launches will likely be strongly uncorrelated with success. If by the time you launch you don’t have escape velocity, you will likely get Sybil attacked¹. Agents will spin up 10 competing products with your same interface. Start...

You can be world-class and still invisible. Just ask Joshua Bell, one of the world’s top violinists... In 2007, Joshua Bell played his $3.5M Stradivarius violin for 45 minutes in a Washington, D.C. subway station. Only 7 people stopped to listen. The same...
Everyone at dinner: Let me tell you about my business idea. Ecom founders at dinner: Quiet because they're actually building and have nothing to prove. Different mindset. Different life.
Most founders talk about innovation. Few know there are 4 types: product, process, business model, and organizational. Cook Medical built new devices, GE Aviation improved manufacturing with automation, fintech startups redesigned digital banking, and Purdue accelerators reshaped how startups grow. Then move through...

What is the most important thing to do next? The answers lie with the customers -- what they want, why they will buy, or stay. Not inside Visual Studio, not in ChatGPT, not on social media. The customer, and you facing the truth.
The headline of this piece should be "Is Stanford for Cowards?" https://t.co/IkzzYak0M8 Favorite line: "People misunderstand what built Silicon Valley. It wasn’t just intelligence. It was the stamina to endure embarrassment, the courage to diverge from the 'ideal path,' and...
Large companies have distribution; startups have innovation, and maybe even a product people love. When each party's weakness maps onto the other's strength, that feels like the kernel of a deal. But typically it isn’t. Here’s how to make it work: https://t.co/tWykmze29I

The most interesting thing about Seedance 2.0 is that clips can be just long enough (15 seconds) to have something interesting happen, and the LLM behind it is good enough to actually make a little narrative arc, rather than cut...

Reading this essay made me ask myself a question: am I using this to „do the thing“ or just to „do a thing?“ Interesting nuance here. I personally use AI very much as a deliberate tool, both in building & running a...
I was at a founders + CTOs event for 10-500 person startups. Founders and CTOs at these companies burn some of the most tokens and increasingly ship a bunch of code to production (when they did ~zero 6 months ago)
