About Duncan
I build the systems I teach.
Every recommendation you'll get from me has been tested against a real business, in production, this week.
Proof of practice
I don't advise on things I haven't shipped.
Three systems I built and use daily. Every client engagement runs on the same tools.
Built by Duncan
Call Trainer
It scrapes data and constructs a digital twin of your prospect. Practise the conversation before the real meeting. A live coaching layer runs during the call, updating deal stage, talking points, next question, and objection handling every turn. Turn-by-turn scored debrief after.
Built by Duncan
Practitioner Hub
The operating system every engagement runs from. 15 packages, deterministic scoring. Governance audits, maturity assessments, programme designs, ROI reports, AI staff registries. Auth-gated: access is part of every engagement.

Prospect Intelligence Platform
Syncs with your CRM's prospect companies. Dual-AI research returns a confidence-scored dossier per account: company overview, use-case matching, discovery questions, and software signals. Territory-scale intelligence without hiring a research team.
I build because I believe you cannot advise on things you have not shipped.
Methodology
The system is the answer.
Prompt, Refine, Deliver, Repeat. Four phases, one goal: capability that stays after I leave.
Phase 1: Prompt - Start from one painful problem
We begin with one pain your team already feels. Maybe launches are dragging. Maybe research never leaves decks. In 60-90 minutes, we pick a single outcome with a board-visible metric, set the baseline, and frame the hypothesis: when we fix this, here's what will change and how we'll know.
Why you should care:
When you start with a specific pain and a metric, you are not buying "AI", you are buying a path to relieve something that already hurts.
By the numbers
Practitioner, not passenger.
Two decades in the trade. AI systems shipped, not slides delivered.
The Playbook
Prompt. Refine. Deliver. Repeat.
The published methodology behind every Duncan Hendy AI Mentoring engagement. 22 chapters of practical AI workflows for B2B product marketers: no fluff, no theory, just the prompts and patterns that work.
