About Growth Signal
Built by Growth Experts, Powered by AI.
Growth Signal started with a plain observation: the teams spending the most on advertising were often the least certain about what that spending was actually doing.
We had all sat in the same meeting. A dashboard is up, the numbers are green, and nobody in the room can say which half of the budget is doing the work. Last-click gets the credit, the channels that created the demand get cut, and the leak widens quietly for another quarter.
So we built the report we always wanted to be handed. Our models read across every channel at once, reconcile what the platforms claim against what actually landed, and put a number on the waste. The output is not a dashboard to maintain. It is a document that names the problem and ranks the fixes.
How we work
Independent by design
We do not buy your media and never will. Nothing in the report is easier to write because of who it lands on.
Evidence over instinct
Every finding names its method and its confidence. Where the data cannot settle a question, the report says so.
Written to be acted on
A finding without an owner and an effort estimate is an opinion. Each recommendation ships with both.
The team
The people behind the report
A small team of three, split evenly between the media side and the data side.
Mara Ellison
Co-founder, Strategy
Spent more than a decade on the buying side, running paid acquisition for retail and subscription brands. She has managed eight-figure annual budgets and rebuilt more measurement frameworks than she cares to count.
Media strategy
Devin Osei
Co-founder, Data
A data engineer by training who moved into marketing measurement after years building analytics pipelines. He designs the attribution and incrementality models that sit underneath every report.
Modelling and engineering
Priya Raghunathan
Co-founder, Analysis
Came up through analytics consulting, where she wrote the audits that finance teams actually read. She owns the benchmarking library and makes sure every finding in a report is defensible.
