Margin before volume
Every target starts at your contribution margin. If more spend will not be profitable, you hear that instead of a new proposal.
About · Tirna Marketing
One operator. Eight years of other people's ad budgets.
Tirna Marketing is Milton von Hesse. No account layer, no pod of juniors. The person who diagnoses your funnel is the person who rebuilds it.
Why Tirna Marketing exists
Most brands are not underspending. They are spending against the wrong number.
Eight years inside marketing teams in Canada and Latin America taught me the same lesson repeatedly: the campaigns were rarely the problem. The targets were. Teams optimised toward a 4:1 ROAS someone had read in a blog post, with no idea what their own margins could carry.
Tirna Marketing started as the consultancy I wanted to hire on behalf of those teams: senior, direct, and willing to say when spending more would be a mistake. Every engagement starts at contribution margin and works outward from there.
The name comes from the cocoon in our mark, the stage where something is quietly restructured before it performs. That is usually what a growth problem needs, not more noise.

How we work
02
One decision a week
Work runs as an ordered queue of experiments, each shipped, measured and written down, rather than a quarterly plan nobody revisits.
03
No handoff
The person on the call is the person in the account. Small by design, capped at a handful of brands at a time.
