You already have the expertise, the judgment, and the experience. What you don't have is a system that makes all of it compound faster. That's what I help you build.
The AI conversation has it backwards. Vendors pitch models and platforms. Consultants demo chatbots. The entire industry assumes the technology is the hard part.
It's not. The hard part is specification — knowing your domain well enough to tell AI exactly what to do, how to evaluate the output, and when to override it. That's a skill built on years of experience, not a weekend workshop.
I call this specification fluency — the ability to translate your hard-won expertise into instructions that AI can execute reliably. It's not a technical skill. It's the skill that makes technical skills compound.
A diagnostic session where I learn your domain, your workflows, and where you're currently spending time that AI could reclaim. You leave with a clear map of where AI compounds your specific expertise — and where it doesn't.
Not a sales call. Not a demo. A real working session between two people who take their craft seriously. Most clients know within 30 minutes whether the Specification Sprint is the right next step.
We design and build one real AI workflow for you or your business in four weeks. Not a proof of concept — a working system you own, understand, and can extend yourself.
Week 1: Discovery — your domain, workflows, and where the leverage is. Week 2–3: Build — we spec and implement together, so you learn the craft of specification as we go. Week 4: Handoff — you run the system independently. I make sure you can maintain, iterate, and expand it. You keep the workflow and the spec. Nothing is locked to me.
Monthly check-ins for clients who've completed a sprint and want a thinking partner as they scale. We review what's working, troubleshoot what isn't, and plan what's next.
This is the compounding phase — you're building on a foundation that already works, and I'm here to make sure each new layer is as solid as the first.
I'm Brian Rothenberg. By day, I'm VP of Pre-Sales Consulting at a compliance technology company. By training, I'm a lawyer and an MBA. By obsession, I'm a builder who owns and operates several small businesses.
I spent the last two months building a sovereign AI infrastructure from scratch — not because I'm an engineer, but because I wanted to understand every layer of the stack well enough to specify it precisely. That project became the backbone of my book, How Hard Could It Be? How AI Compounds the Experience You Already Have.
Everything I offer clients comes from work I've done on myself first. The frameworks, the specification practices, the mistakes — all real, all documented. I'm not selling theory. I'm sharing a path I've already walked.
The Deep Dive is the best place to start. 90 minutes, $135, and you'll know whether this path makes sense for you.
