The Problem
Companies that invest more and grow less due to lack of procedures
Most companies work short-term to push sales: quarters, months, reactive decisions. They add more people, more investment and more effort, but growth gets noisy and never sustains over time.
Effort, investment and hours
Goes up every month
Real profitability and clarity
Stays flat
The world moves toward AI and more efficient procedures. Profitability does not grow by adding hands — it grows by building solid systems that hold even when people change. That's why I work with a 1 and 5-year plan: first we put it in order, then we scale.
Do you recognize this curve in your company?
Approach
My concrete analysis of your business
I work on all the key areas of the business: marketing, sales, internal processes, team organization and applied artificial intelligence — always aligned with your goal of revenue growth and company profitability.

Differentiation
I get inside your company to understand it 100%
I design a 1 and 5-year plan, not short-term patches
I define the full business horizon. The short term gets executed without losing the strategic direction.
I work with AI every day, not as a trend
I stay up to date with the tools and models that appear every week. I apply AI where it increases profitability — not as fashion, but where it makes sense for your business.
I founded 5 companies and apply my learnings
I run The Funnel Box, Brainstorming Films, Veribox and Echoroutes. What I recommend I have tested myself first — I know what hurts, what works and where the real bottleneck is.
We work with multiple industries in parallel
Retail, e-commerce, professional firms, aesthetic medicine, B2B, education. Every client brings us data and patterns that we apply to the next — it's a constant learning flow that multiplies the value for you.
I accept a maximum of 5 new companies per month to guarantee real dedication, depth and measurable results. If your company is the next one, let's talk.

Let me tell you who I am and why you should choose me
The criteria behind every decision
The difference between selling and scaling rarely lies in what a company does, but in what it isn't seeing.
I learned this by leading the transformation of a family business with over 30 years of history that, after two crises and an exhausted model, managed to evolve into a reference in its sector in Spain.
That's when I understood the key: the problem isn't effort, it's the lack of clarity.
Many companies do more, invest more and work more, but without real direction. That leads to inconsistent decisions, unsustainable growth and loss of control.
That's why I work in a different way.
Not as an agency.
Not as an external provider.
But as a partner who steps inside the business, understands how it really works and acts on what truly has impact.
If we work together
- Clarity in decision-making
- A more structured and predictable business
- Sales less dependent on peaks
- Decisions based on data, not intuition
It's not about doing more.
It's about doing what actually moves the business.

Conocí a Gonzalo cuando buscaba un especialista en marketing digital que me ayudara a expandir mi negocio de Formación y Desarrollo. Gonzalo realizó un estudio completo de mi negocio y creó una estrategia a corto y largo plazo que me permitió captar nuevos clientes y aumentar mis ganancias. Le apasiona su trabajo y también mi negocio y mis objetivos. Logró comprender mis ideas y simplificarlas para hacerlas prácticas. Una ventaja adicional fue su experiencia en el ámbito del e-learning, ya que ha creado varios cursos online excelentes para el autoaprendizaje sobre marketing digital. Me sentí muy cómodo trabajando con él porque sentí que su principal motivación es ayudar a las personas a alcanzar sus sueños.
