Build the implementation team around two complementary forms of expertise. The domain specialist understands the existing workflow, its personas, historical experiments, operational constraints, and what a useful output looks like. The AI specialist understands model behavior, data pipelines, retrieval, training, and technical iteration. Give them a shared business outcome and have them inspect production behavior together. The domain expert diagnoses relevance and workflow failures; the AI expert converts those findings into changes to prompts, data, models, retrieval, or system design. Keeping both perspectives involved through launch and iteration reduces the risk that the team optimizes technical novelty instead of solving the user's actual problem.
Origin
Extracted from Marketing Against The Grain after HubSpot credited the partnership between its email automation specialist and AI specialist as an important implementation lesson.
Core principles
- 01Technical AI skill does not replace workflow knowledge.
- 02Domain experts preserve context about users, personas, and operations.
- 03Close collaboration converts an AI capability into a relevant business system.
- 04Both experts should share ownership of outcomes.
How to run it
- 1
Define the target workflow
Choose a concrete business process and state the user and business outcomes the AI system should improve.
Pro tip Select a workflow with measurable baseline performance.
Watch out A vague mandate to use AI makes ownership and evaluation difficult.
- 2
Assign the domain expert
Choose someone with deep knowledge of the workflow, audience, personas, automation, and historical edge cases.
Pro tip Favor hands-on operational knowledge over title or seniority alone.
Watch out Do not reduce the domain expert to a late-stage reviewer.
- 3
Assign the AI expert
Choose someone capable of building and iterating the model, data, retrieval, and integration components.
Pro tip Ensure the AI expert can observe production outcomes rather than only deliver a prototype.
Watch out Technical expertise without access to domain context can optimize the wrong behavior.
- 4
Create shared measures
Agree on relevance, user-value, quality, safety, and business metrics that both experts own.
Pro tip Include qualitative output review alongside conversion or productivity metrics.
Watch out Separate incentives can cause each specialist to declare success while the total system fails.
- 5
Review and translate failures
Inspect real outputs together. Let the domain expert explain why an output fails the workflow and the AI expert identify which technical mechanism should change.
Pro tip Maintain an annotated set of representative good and bad outputs.
Watch out Avoid treating every domain failure as a prompt-writing problem.
- 6
Iterate as one team
Keep the pairing intact through deployment and repeated improvement rather than handing the system from one function to another.
Pro tip Use short review cycles during early production use.
Watch out A clean organizational handoff can sever the feedback loop the model needs.
In the wild
An email automation specialist brings detailed knowledge of first-conversion nurturing, personas, and existing email operations. An AI specialist builds and tunes the inference and recommendation system. Together they review whether the system understands each contact's likely goal and whether the selected content genuinely helps.
→ The implementation combines technical feasibility with workflow relevance and produces a stronger nurturing experience.
Common mistakes
Building with AI expertise alone
A technically capable system can still misunderstand the workflow, audience, or definition of a valuable recommendation.
Using the domain expert only for approval
Domain knowledge must influence requirements, data interpretation, testing, and iteration rather than appear only at final sign-off.
Giving each expert different goals
The pairing breaks down when one person optimizes model sophistication while the other is accountable only for business metrics.
Is it for you?
Best for
It is best for AI systems embedded in specialized workflows with established audiences, rules, or automation.
Not ideal for
It is not ideal as a substitute for broader security, data, legal, or product expertise when those functions are also necessary.
From the transcript
“Pairing the two together has also been, I think, yeah, really important.”
“So you have a marketing uh someone who is just a subject matter expert in the automation work, the persona, the email. And then you…”
