Our mission

Make every pound of marketing spend easy to read, defend and grow.

Since 2016

Our story

We started Tidemark because agency reports made no sense.

Our founders spent years inside big agencies sending 30 page decks full of impressions and click through rates. Clients nodded along and still could not tell if marketing was working.

So we built the opposite. One team running every channel, one weekly report written in revenue, and a promise: if we miss the targets we agree, the next month is on us.

How we work

Four rules we never break.

These shape every hire, every proposal and every report we send.

01

Revenue over reach

We report what made money, not what looked busy.
