The Founder's Wire, October 16: Character.AI Files Chapter 11, Accenture Caps Claude at $29 — Two Readings of the Same Clock
A billion-dollar startup that sold its founders to Google now files for bankruptcy; the world's biggest consultancy meters Claude at $29 a head. Both are the same story — the free-money, all-you-can-eat phase of AI is ending — told from the buy side and the sell side.

AI Wrapper Gross Margin: How to Calculate the Unit Economics of Reselling LLM Tokens
Your margin is not your vendor's 85%. It's what survives the tokens the customer never sees — the retries, the tool loops, the system prompt re-sent every turn. Here's the formula, with a worked example.

The Founder's Wire, October 15: Anthropic Opened Its Books — $16.8B, an 85% Margin, and $1.70 of Revenue for Every $1 of Compute
At its pre-IPO investor day, the company your agent runs on disclosed the one number that should change how you price your own product: it keeps 85 cents of gross profit on every compute dollar. That margin is the ceiling you resell under.

The Founder's Wire, October 14: Gemini 4 Argon Opens Its Gate — and Now Three Frontier Models Cost Exactly the Same
The million-token model you couldn't buy on October 3 went live to every developer on the 13th — at $2/$10, the identical price as GPT-6.1 Sol and Claude Sonnet 5.5. When three labs independently land on the same number, price stops being the lever. Here's what moves instead.

Tokens per Watt: The Inference Benchmark That Isn't About Your Electricity Bill
Microsoft led the Maia 300 launch with tokens-per-megawatt, not FLOPS. Here's what the metric actually measures, the back-of-envelope math, and why it changes which vendor claims deserve your attention — even though the energy itself costs pennies.
