- Your last launch missed. The post-mortem was a feeling.
- Every campaign call still ends up on your desk.
- You know AI should cut production cost. Nobody has started.

The model needs about USD 115K a month in online sales to pay off for both of us. Ask for the Growth Leak Check: twelve questions that show where your budget leaks.
Get the Growth Leak CheckOwners ask
Why not hire a full-time marketing director?
You can. Expect a full salary plus bonus, months of searching and no AI system on day one. Three weeks shows you which model wins.
Do you replace my marketing lead?
No. They run the team. I own strategy, budget and results.
Why net sales and not revenue?
Returns and discounts are real costs. Paying me on revenue would reward discounting.
Can we commit to three months?
Results need two quarters. From month 3, if ROAS sits under baseline two months running, you can leave.
Do you work outside Vietnam?
Yes. Based in Ho Chi Minh City, working with brands across Asia-Pacific.
What do you need to start?
Read access, twelve months of data and one hour with you and your marketing lead.
Who owns the work?
You do. All of it.
