This GTM AI Gave Away its OWN Secret
AI startups offer to run your GTM for a subscription fee. Here's the Claude Code prompt to build the same system yourself, one CLAUDE.md, and you own every part of it.
The hottest trend in GTM right now is outsourcing your brain to an AI.
A few months ago, an AI startup (Gooseworks) wanted to run my GTM for me.
YC-backed, an AI coworker with its own computer, email, skills and memory. It would run outbound, manage the CRM, and I’d approve its work from Slack.
A client asked me last month whether he should just pay for one of these instead of learning Claude Code.
“Why would I build it when I can hire it?”
Fair question. Here’s what I told him:
The blind spot in every managed AI
These tools execute fast. What they can’t do is fix what you feed them:
A vague Ideal Customer Profile gets automated into vague outbound
Generic signals become generic campaigns, run faster
Untested messaging gets scaled instead of tested
The strategic thinking still has to come from you. No tool changes that, whichever logo is on the invoice.
Which means the real question was never “AI or no AI.”
It’s which camp you join:
💳 The Renter
Pays monthly for a managed AI coworker
Fast start, polished interface, someone else’s roadmap
Owns none of it: the prompts, the data, the logic and the off switch all belong to the vendor
The day the pricing changes or the startup pivots, his entire GTM walks out the door with it.
That’s not a hypothetical anymore.
Gooseworks still says “runs your GTM” on its homepage.
But three months on, what it’s actually shipping and pushing hard isn’t an autonomous coworker running your outbound.
Now it’s a tool that remixes ad templates for Meta.
🛠️ The Builder
Creates the same system in Claude Code
Slower first week, then compounding every week after
Owns everything: the CLAUDE.md that encodes his customers, every prompt, every learning, at a fraction of the platform fees
Nobody can raise the rent on his own brain.
Even the AI startups know it
Here’s the detail that gives it away:
Gooseworks open-sourced every skill its AI coworker uses, both before the pivot and after.
That includes the exact skill that now makes the ad creative they charge you a subscription for.
Anyone can install it straight into Claude Code, for free.
Think about what that means. They’re charging monthly for something you could build yourself with the same free parts already handed out.
The subscription is the business, not the product.
The value was always the system underneath it, the one he open-sourced.
And when the big ambitious version of the company got hard to keep running, that free, owned system is the part that survived.
Lay the first brick today
The renter’s advantage is speed to start. So remove it.
The builder’s first brick is a CLAUDE.md, the file that teaches Claude Code who you sell to, and it takes one conversation to draft. Here’s the master pronpt:
