Michael Fafinski, owner of Gutter Galaxy, is back on the Reasonable Contractor podcast. Six months after his last visit he's cut the homeowner division, gone B2B, and rebuilt how he runs the company around an AI second brain. He's maxing out Claude's $200 plan every week, and he's not writing code. He's running a gutter business.

We get into the real mechanics. An AI executive team trained on actual business books, whole books digested into frameworks the AI loads on demand, and everything in plain folders Michael owns, so no software company can hold his business hostage. Ryan shares the engineer trap rule that stops him from building things nobody asked for, and the 500 pages of estimating tables he scanned into his vault. About 40 focused hours is all that separates you from the people doing this.

Takeaways:

* A second brain is plain text folders the AI reads. You own it and can move it to any AI, any time

* Michael trained AI executives (a CEO, a CRO) on real business books so strategy answers come from real frameworks

* With a vault plus voice dictation you talk to the AI like anoal work

* 95% of people still use AI like a search engine. About 40 focused hours puts you ahead

* Don't wait for the perfect structure. Having a second brain at all is 90% of the battle
