USAAreas of Intervention
The Pillars of The Funnel Box
We analyze the company from within, define the strategy and execute to build your company's profitability.

Business Consulting
We analyze the complete structure of the company: model, marketing, sales and operations.
We detect what is limiting growth, define a clear strategy and act on the areas that have real impact.

AI Consulting
We identify where artificial intelligence can improve processes, optimize resources and increase operational efficiency.
We design and implement solutions applied to the business, integrated with marketing, sales and internal systems.

Brand Positioning
We build the digital presence your company deserves: website, first page of Google and recommendations from ChatGPT. Real cases, measurable results.
We work on technical SEO, positioning content, brand authority, GEO for AI engines and web design that converts.
Process
How we approach each project
We don't work short-term.
Every intervention is designed for the long term, as a structure upon which everything else is built.

Diagnosis
Gonzalo Castro will conduct consultations to understand your company from within, detecting needs, strengths and weaknesses, and planning the best growth strategy with the team.
Not only active listening, but also data analysis and previous work review to understand everything that is currently happening.

Quality over volume. Always.
We are not an agency for everyone.
And we don't try to be.
At The Funnel Box we work with a limited number of clients because each project requires real focus, strategic thinking and hands-on execution. Without that, it doesn't make sense.
We prefer few relationships, but deep and long-term.
The kind that generate sustained impact, not isolated results.
If there is no alignment in the way of working, in the level of demand or in the vision of growth, we simply don't fit.
And that's okay.
