The Inference Economy: Token Use (11 minute read)
Token demand is going up. Everyone should be thinking about how to manage token usage as models will get more expensive as they get better. Businesses need to consider whether they are using the right-sized model for their project and whether reasoning is really required. They need to be flexible with providers and only use fine-tuning/post-training if they have enough data, expertise, and resources.
Paying to Win: The Rise of Veblen Services (3 minute read)
Veblen services are professional services where price signals credibility and assurance. At the top end of several industries, high fees are a signal of quality. Hiring the most expensive firm becomes a form of insurance. In this environment, lowering fees raises doubts, and discounting looks more like a weakness.
The New Underutilized Sales Trick You Can Steal (7 minute read)
Add an "Ask AI" button to your landing page. The button opens ChatGPT, Claude, or Perplexity with a pre-filled prompt about your product. The user clicks, the AI explains, and the explanation feels less like marketing because it didn't come from you. A landing page is obviously self-interested. An AI assistant feels like a second opinion. The execution matters. If the prompt says "tell me why this product is amazing," it reads as fake. The stronger version asks what a real buyer would ask, including where the product might not fit. The balanced answer is the persuasion.
The Most Fun I've Had Building Apps: GPT-5.5 + GPT-Image-2 (4 minute read)
Paste a screenshot of an app into Codex. Codex builds it, then opens a browser and compares the running app against the original screenshot. In the Artemis II example, Codex pulled real NASA mission data, noticed the screenshot's Earth-to-Moon ratio was wrong for the actual mission, and interpolated a flight path that preserved the visual without lying about the physics. The system treated the visual as design intent, not gospel. The bottleneck stops being "can you make the first version" and starts being "can you tell what's off."

Users have the option to make sure the tool requests approval for every transaction.

Make Friends With Your Market (5 minute read)
Most teams pay for the booth, then waste the room. They sit behind a table, check their phones, and wait for obvious leads to walk up. Meanwhile, the openings are everywhere. Someone slowing down for half a second. Holding eye contact. Touching a brochure. The move isn't a pitch. It's an easy invitation. The piece also makes the case for talking to neighboring booths, not just buyers. One 20-minute conversation with the booth next door led to an intro into a customer segment the company hadn't considered.
Pre-seed Is Not Cheap Seed Investing (5 minute read)
Besvinick rebuts Lucas Bagno's "Great Bifurcation" thesis that low-priced rounds signal adverse selection, arguing pre-seed at $5M-$15M post operates on a different risk profile than $40M-$100M seed rounds and rewards backing founders before consensus forms.
A Costume Called Conviction (4 minute read)
Most VCs call themselves conviction investors. What they usually mean is they'll move quickly when a founder fits an obvious pattern: AI company, elite school, prior exit, hot market, clean memo. Real conviction is expensive. The founder is strange, the market is unproven, and the memo is ugly. The piece names this the "legibility tax." Every layer of institutional capital strips away weirdness so the deal can be defended internally. If you're building something non-obvious, you need one person willing to look foolish before the room agrees.
