I first heard the Wanamaker quote from a client, and he wasn't quoting it fondly.
We were about forty minutes into a budget review. He'd been patient, I'd been explaining, and at some point he just sighed and said it. Half the money I spend on advertising is wasted, I don't know which half. Then he looked at me like, well?
I didn't have a good answer. That's the honest bit.
Nobody's quite sure who said it originally, by the way. Usually pinned on John Wanamaker, sometimes Lord Leverhulme, no solid source for either. The most quoted line in marketing and we can't even attribute it. There's a joke in there somewhere.
Over a century old. Still the most accurate description of most marketing budgets I see.
And that should embarrass us, honestly. We've had a hundred years. We built click tracking, pixels, attribution windows, whatever this year's platform calls its conversion model. Every single one of those arrived promising to close the gap.
What did we actually get? A much higher-resolution picture of not knowing.
Because Wanamaker's problem was no data. Ours is the opposite, and it turns out that's just as useless. Six tools all reporting, all disagreeing, none of them talking. Google Ads marking its own homework. GA4 counting some other way. The CRM sitting on the actual money, speaking to nobody. Four confident answers, no way to pick between them.
Which is worse than having none, I think. At least none is honest.
So the modern version of the quote goes: half my budget is wasted, I still don't know which half, and now I've got a dashboard insisting it does.
That's the gap we built Agentcroft Insights for. Not a seventh opinion on the pile. Joining the lot up and putting a brain on top of it, something that remembers what happened last quarter, holds thousands of data points in context, and works out the link between the thing you did in January and the money that turned up in March. Attribution tells you what got credit. The brain tells you why. That second bit is what my client was actually asking for that afternoon, and what I couldn't give him.
Have we solved a hundred-year-old problem? No. Daft thing to claim.
But I do think knowing which half has finally become a technical problem instead of a philosophical one. That feels like a real shift to me.
We're putting it in front of a room full of strangers on Product Hunt next Wednesday, which will tell us fairly quickly whether that holds up.
If you've ever done the Wanamaker shrug in a budget meeting, come and watch.
