The Marketing Builder · A monthly letter from Roberto Ercole

How a $2B firm runs marketing on AI.

Once a month: the systems I actually run — the agents, the numbers, what broke, and what it returned. Written for marketing leaders who want the machine, not the hype.

You’re in.

The next issue lands in your inbox — and I read every reply.

What you get

01

One system, taken apart — the architecture, the cost, the result.

02

The numbers that mattered this month — cost per lead, hours saved, what got killed.

03

What broke, honestly — so you don’t build it wrong.

Inside the current issue

The WhatsApp responder that qualifies leads while I sleep

It replies in under a minute, asks the three questions a rep would ask, and only hands a human the ones worth a human.

Negative keywords, run by an agent that never gets bored

Every week it reads the search terms, kills the waste, and shows me what it saved. Cost per lead stopped drifting the month I switched it on.

Meetings that end with the tasks already assigned

Notes go in, actions come out with an owner and a date. Nobody writes a recap anymore, and nothing quietly falls off the list.
