SO YOU WANT TO SELL INFERENCE

AI companies selling inference face a zero-margin, cost-plus pricing dilemma. They can achieve better margins through value-based pricing, charging based on outcomes rather than raw inference costs. Optimizing inference costs using model routing, caching, and distillation can also enhance margins and offer a competitive edge.

COMPANIES THAT BUILD COMPANIES

Polsia, a startup with AI agents instead of employees, claims $10M in annual revenue, illustrating the rise of companies building companies using AI. Both Polsia and YC-backed Thomas focus on AI-driven business models promising to innovate startup creation. While most ventures may fail, the few successful ones could prove lucrative, resembling Shopify's model where only a small percentage of ventures succeed significantly.

HOW TO STEAL A CUSTOMER BASE

The fastest way to take a competitor's customers is to leave them nothing to walk away from. Cursor didn't ask developers to switch off VS Code, it forked VS Code, so every extension, shortcut, and bit of muscle memory came along for free, then rebuilt the engine around AI underneath. Microsoft can't simply copy that back, because rebuilding VS Code that deeply would put its whole extension ecosystem at risk, so it won't, and that refusal is the counter-positioning that holds the door open.

7 MISTAKES FOUNDERS MAKE WHEN CHASING THEIR FIRST DEALS

Founders often delay selling for product perfection, underprice their offerings, and rely too much on a single customer. They should identify decision-makers, listen more than they speak, and adapt their pitch continuously. Early-stage technical founders must personally handle sales to fine-tune their approach before hiring dedicated salespeople.

AI AGENT HYPE MEETS REALITY: THE PRODUCT DOESN'T WORK (AND CHURN IS COMING)

Instead of building a superagent that does everything, make the focus as narrow as possible. Make sure your product has been extensively tested and that it works in real-world conditions. Companies that promise everything but produce AI slop will lose customers quickly. This churn makes growth impossible to maintain.

EVERY MOAT BECOMES MOOT

A good reframe of what a moat actually is. It's not a static wall like a patent or a network effect, it's an engine that only keeps working if you stay willing to do the uncomfortable, repetitive thing rivals won't. Amazon is the example, the thin margins that look like weakness are the wall, because fat margins are really just a fund for your competitors' R&D. The moat that lasts isn't any single advantage, it's being able to build the next one faster than the current one erodes.

SLOP AS A SERVICE

The "AI-generated" label doesn't make a bad video good, doesn't stop the feed from filling with junk, and doesn't tell you whether something is accurate, ethical, or just stolen and spun up for ad money.
