INTRODUCING CODEX

OpenAI just launched Codex, an autonomous coding agent that writes features, fixes bugs, and submits pull requests in isolated cloud environments. Companies like Cisco and Temporal are already using it to handle entire codebases while their engineers focus on higher-level work. The agent can tackle multiple tasks simultaneously, run tests, and provide detailed citations of every change it makes.

CHIME IPO: S1 BREAKDOWN

Sometimes the most profitable customers are the ones everyone else calls "unprofitable." Chime built a $1.67 billion business serving the 70% of Americans making under $100K - customers traditional banks actively avoid. It isn't actually a bank - the company just handles the customer experience while partners deal with regulatory headaches. Users swipe 54 times monthly because Chime doesn't charge overdraft fees. The model works: it earns money on every swipe without owning the banking infrastructure.

GTM EFFICIENCY IS PLUMMETING!

Cloud companies are making record profits but burning more money to get each new customer. Today's strong margins come from customers they acquired cheaply years ago. Current sales teams cost way more to land new deals. When those old, profitable customers eventually leave, companies will replace them with expensive new ones. FCF margins look great now, but will crash later unless sales efficiency improves.

HOW TO IDENTIFY AND INVEST IN TOP TALENT

When you double team size, employee performance becomes harder to track. Two frameworks can help: the 9-box model plots employees on performance vs potential grids, while stack ranking forces leaders to rank everyone from top to bottom. Both create uncomfortable but necessary conversations about who deserves investment, coaching, or exit plans.

HOW TO STOP HOLDING YOURSELF BACK

Everyone stays muted on Zoom hoping nobody notices, but that is just self-sabotage disguised as humility. We give ourselves "free passes" to play small - staying silent in meetings, not negotiating offers, waiting for perfect moments that never come. If you know what needs changing in your role but haven't done it, you're giving away your power.

FINDING "GOOD" DEMAND

Two criteria separate fast growing startups from slow ones: First, how likely is your solution to be the customer's #1 priority right now? When a project tops their list (like Lovable for UI mockups or Vanta for SOC 2 compliance), customers actively seek solutions. Second, how dramatically better are you than alternatives?

WHEN CUSTOMERS BUY YOUR COMPETITOR'S PRODUCT… AND THEN BUY YOURS

Enterprise sales doesn't have to mean 6 to 9 month long deals. 20 years ago, a hospital had million-dollar HP OpenView monitoring software and also bought What's Up Gold for $500. Both do the same thing. Its explanation: "What's Up Gold has features we use daily, and $500 goes on the credit card without approval." No procurement meetings, no sales cycles. Sometimes the back door is just pricing under the credit card limit.

WHAT'S GOING ON WITH AI PROGRESS AND TRENDS?

AI progress stems from faster algorithmic advances and increased compute for training, with the trend of training compute growth expected to slow from 4.5x to around 3.5x annually. Returns to pretraining are diminishing, shifting focus towards scaling up reinforcement learning, though this brings its own challenges, like environment scalability. Despite some bumps, notable algorithmic improvements have accelerated to potentially 4.5x effective compute per year, primarily driving advancements over merely increasing raw compute.

THE SLOW DEATH OF INDIVIDUAL TASTE

Ever notice how everyone looks exactly the same now? Compare today's algorithmic cloning to photos of individuals from the 70s-90s who looked effortlessly chic in their own distinct ways. We've traded browsing local boutiques for keyword bidding wars and influencer FOMO. Now we scan, click, and purchase, becoming complicit in our own taste erosion.
