AI STARTUP TEARDOWNS · WEEKLY

Most AI startups won't survive. Here's how to spot the ones that will.

Every Wednesday, one AI startup is torn apart. The tech, the unit economics, the real moat. Written by an engineer who builds AI agents and has stopped believing the press releases.

Anthropic's Close to $1 Trillion Valuation Runs on Compute It Doesn't Control

$47B in run-rate revenue. Nearly profitable. A $965B valuation. Yet the infrastructure underneath it belongs to someone else.

Most of the AI companies burn investor money and call it growth. Anthropic is the rare exception, the revenue is real, and they are expecting a profit in Q2.

Its run-rate (annual projected revenue) went from about $9B to roughly $47B (5x) in five months. It then raised $65B at a $965B valuation and filed to go public.

But the compute behind all of it is rented, about $15B a year, from a competitor SpaceXAI, cancellable on 90 days' notice, and this is not the only deal Anthropic made. So how solid is the most solid business in AI?

HOW THIS IS DIFFERENT

Four rules every issue follows

The reason this newsletter exists.

No hype, no fear

I'm an AI engineer. I've seen the inside. The hype is manufactured. The fear is misplaced. You'll get neither here.

Business first, tech second

If the financials don't work, the technology doesn't matter. Every teardown starts with the money.

Written by a builder

I build AI products for a living. I understand the founder's psychology and what they're not telling you.

One company, deep

No news roundups. No tool lists. One company per week, torn apart properly. That's the whole product.

I am an AI engineer building agents professionally. I got caught up in the AI hype like everyone else then I built a mental model to see through it. Model Breakdown is exactly that lens, made public. I write about what I see from the inside.
