Stop Burning Money on Marketing Experiments That Never Ship
Your Marketing Team Wants Speed. That Ship. Not More Tools.
The problem with "AI marketing" isn't the AI. It's everything else.
You've seen the demos. Content that writes itself. Ads that optimize while you sleep. Workflows that turn one brief into fifty pieces of marketing.
But when you actually try it?
- Quality drops so fast your brand team revolts
- Nothing connects to anything else
- You spend more time editing AI output than writing from scratch
- Legal freaks out about compliance
- And somehow you're busier than before
Here's what's actually happening: You're trying to solve a systems problem with a tool problem.
Ship More With a Smaller Team (With Guardrails)
I'm Duncan Trevithick. For 8+ years, I've built marketing systems that grow revenue while cutting wasted effort.
Not marketing "strategies." Not more content. Systems.
The kind where you input a brief on Monday and multi-channel output ships Friday—with human review where it matters, automation where it doesn't.
Recent wins:
- 25% leads growth managing content across 3 brands at LXT.ai
- Cut weekly content production from 40h to 8h while tripling output
- 5x YouTube ROAS for Koinly during Australian tax season
- Tripled organic traffic YoY for potential.ly SaaS platform
- Built AI workflow that processes 100+ property analysis events daily
Leadership goals:
- Faster time-to-market for campaigns and content
- Reduced cost per acquisition through automation
- Risk management with compliance and quality controls
- Measurable ROI on marketing technology investments
- Team efficiency gains without adding headcount
The Real Problem: Everyone Talks AI, Nobody Talks Plumbing
You don't need another "AI consultant" who shows you ChatGPT tricks.
You need someone who builds reliable plumbing between your brief and your results.
Here's what that actually looks like:
Retrieval from approved sources
(no raw model hallucination)
- Your style guides enforced in every prompt
- Brand voice templates that actually work
- Content pulled only from pre-approved knowledge bases
Every workflow logged, versioned, easy to turn off
- Transparent scoring instead of "black box" decisions
- Weekly change notes your team can actually read
- Auto-rollback when quality dips below threshold
Human-in-the-loop where it matters
- Staging queues for everything public-facing
- Confidence thresholds that auto-route for review
- Legal gets a simple data map on day one

Stop Paying for Experiments. Start Shipping Systems.
The difference between "AI marketing" and actual results:
| What everyone else sells | What you actually get |
|---|---|
| "AI will revolutionize everything!" | Working automations tied to real outcomes |
| Flashy demos | Before/after numbers on speed and quality |
| "Trust the algorithm" | Screens of monitoring, scoring, rollback plans |
| Implementation "someday" | Short pilot showing reduced manual work |
