About me

I’m Jaime. I help you decide with data.

I’ve spent years helping businesses understand their market, listen to their customers and build strategies that keep growing. JMdB Growth is the structure behind that work: you get a method, not just me.

What makes me different is speed with judgement. I use AI and up-to-date research methods in every study and diagnostic, so you get rigorous analysis in days, and for a fraction of what a large consultancy would charge.

How I work

Four principles

Clarity first

No jargon. If it doesn’t help you decide better, it’s out.

Data, not opinions

Every recommendation is backed by at least one real, verified data point.

Fast, without lowering the bar

I use AI as a tool to deliver in days what others take weeks to produce. The analysis and the judgement are still mine.

Focus on your customer

Grow muscle, not fat: get more out of what you already have before spending more.

Got 15 minutes to talk?

Tell me what decision you’re facing and I’ll tell you, with no strings attached, whether I can help and how.
