This is the MentorMe Blog — field notes on running a business without a team standing behind you. Every post covers the same three lanes: AI agents you can actually put to work today, the systems that keep a one-person operation from breaking under its own growth, and the exact prompt patterns and Claude Code workflows we use to run this company. It's written for solopreneurs, bootstrapped founders, and anyone doing the job of five people who's tired of guessing. No theory pieces, no listicles padded with filler — each dispatch is a real move pulled from something we built, broke, or fixed this week, written down the way we wish someone had handed it to us. New dispatches post weekly, usually Tuesday and Thursday, and every one links to a related deeper resource — a tool, a playbook, or the founding program — so you're never stuck reading without a next step. Skim the headlines below, find the one that matches the problem you're actually stuck on right now, and go build. Reading the route isn't walking it — but it's the fastest way to stop guessing which direction to move next.

These are written the way we wish someone had written them for you: from inside the work, while the dust was still settling. No theory. The actual moves.
But reading the route isn’t walking it. When you’re ready to stop being the only engine in your business, the next page builds you a plan.
Read one. Steal what works. Then go build.
