About
Trevantodes exists because too much marketing money is spent on activity nobody can connect to revenue — and because the people who diagnose that problem are rarely the people who then do the work.
Our story
We spent years inside agencies and in-house teams watching the same pattern repeat. A brand hires an agency. Senior people run the pitch and the first month. Then the account quietly moves to whoever is available, reporting becomes a monthly slide with a green arrow on it, and eighteen months later nobody can say which of the spend actually caused any of the growth.
The uncomfortable part is that this usually is not incompetence. It is structure. An agency paid a percentage of media spend has no reason to tell a client to spend less. An agency that owns the tracking, the accounts and the dashboards has no reason to make any of it portable. An agency with thirty accounts per manager cannot afford the hours that a real diagnosis takes.
So we built the opposite, and accepted the consequences. Fees are fixed and unrelated to media spend, which means our incentive is efficiency rather than volume. Everything we build lives in accounts the client owns, which means leaving us is inconvenient rather than catastrophic. And we cap how many accounts we take, which means we grow slowly and turn work down.
The tagline is not a slogan we reverse-engineered. It is the test we apply before accepting an engagement: if we cannot see a credible route to this work paying for itself, we say so and decline. That has cost us revenue. It has also meant we have never had to defend a number we did not believe.
Trevantodes is registered in Denmark and works in English with clients across Europe and North America. Most of our work is remote, which is fine: measurement problems do not respect geography.
What we hold to
Values are only real if they are inconvenient. Here is what each of these actually costs us.
You get raw access to every account, dashboard and test log — not a curated summary. Fees are fixed and never a share of media spend, and platforms bill you directly with no mark-up.
What it costs us: we lose the upside when a client's budget grows, and our mistakes are visible the week they happen.
We will not scale a channel we cannot measure. If tracking is broken, fixing it is the first invoice, even when the client would rather we just launched campaigns.
What it costs us: a slower, less exciting first month, and occasionally a prospect who wants activity immediately.
The person who audits your account is the person who runs it. No juniors learning on your budget, no account manager relaying questions to someone you never meet.
What it costs us: we cannot scale by hiring cheaply, so we cap the client list and turn work away.
We optimise for the cost of growth twelve months out, which usually means building organic and creative assets alongside paid rather than chasing a good quarter.
What it costs us: our first ninety days look less impressive than a discount-led spend increase would.
