Your marketing campaign companion.

A campaign is a specification, not a black box.

Most performance marketing is opaque. A retainer is paid, ads appear, a monthly PDF arrives, and if the relationship ends the client inherits a login and no understanding of what is in it.

Campagna runs campaigns as readable specifications. Budgets, targeting, ad groups, keywords, negatives, and copy, written down in a file you can open.

1. The spec

   The whole campaign in a readable file. Not a report about the campaign. The thing itself.

2. The diff

   Every proposed change is shown as a difference against what is live now. You see exactly what moves and by how much, before it moves.

3. The approval

   A person reviews the diff and says yes. Money moves only after that. AI agents do the research, draft the spec, compute the diff, and mine search terms for negatives. They do not have the authority to spend. That boundary is enforced in code, not in a prompt.

4. The log

   Every applied change is recorded alongside the operation that would undo it. Nothing is unexplained after the fact, and nothing is irreversible.

Paid ads at one end, answer engines at the other, measurement holding the middle.

• Google Ads campaignsBuild, launch, and run search campaigns. Brand, product, and competitor.
• Keyword researchVolume, intent, and competitor gap analysis. Feeds the campaign spec directly.
• Campaign strategyStructure, budget allocation, match type policy, and negative strategy.
• Server-side conversion trackingMeasurement that survives browser restrictions and ad blockers.
• Google Tag Manager setupContainer build, tag hygiene, and consent configuration.
• Answer engine optimisationEntity clarity, content structure, and tracking whether you are cited across AI answer engines.
• The workspaceResearch and monitoring tools you use yourself, with the work visible in one place.

Two of those are measurement rather than advertising. That is deliberate. Measurement is the part most agencies do badly or not at all, and it is the part that makes everything else provable.

Built to be checked.

The approval boundary is not negotiable. A system that can spend your money unsupervised cannot also be a system you audit, so agents research, draft, and propose, and a person decides. Everything they propose is written down before it happens and recorded after.

The practical test of that is simple. The specification is yours and so is the change history, which means at any point you can read what was built and every decision that shaped it. Most of the value of that is not in leaving. It is in never having to wonder.
