I'm an engineer building AI in public — and a marketer who makes it pay.
I'm Brian MacDonald. Twenty years running marketing and lead-gen operations, the last few architecting AI systems that do the work — and I'm building all of it in the open. Follow the build, or put the same systems to work in your business.
I don't theorize about AI. I run it — in real marketing operations. Two decades in the trenches of lead generation, marketing operations, and team-building for founders and agencies. The last few years architecting AI systems that take the work bleeding your team's hours and hand it back as revenue — freeing your best people for the work only they can do.
I architected and shipped my own platform, Mavrick, end to end — an AI coworker that calls new leads in under 60 seconds, qualifies, books, and follows up, and runs marketing and lead-gen work natively in Slack. It's rocket fuel for a lead-gen operation: it clears the repetitive work off your team's plate so your people spend their hours where they actually move revenue. Living proof the kind of AI I build works in the wild — not in a slide deck. See Mavrick →
78% of buyers go with whoever responds first · median company takes 42 hours · only 7% hit the five-minute mark · ~9× swing on speed alone.
One example — speed to lead. Every operation has a dozen more. Finding yours is the job.
Want the operator's read on your business?
I get into your marketing and lead-gen operation with you, find where AI pays off first, and you leave with a plan you can run. Not a sales call — a working session with a deliverable.
A free strategy call with the operator who builds it. The AI Concierge is $997 — we cover it on the call.
New guides, as I ship them.
I'm building Mavrick in the open and writing down what works. Drop your email and I'll send new guides and playbooks as they publish — no fluff, no spam.
