What our clients say
Pedro Miralles
Congratulations to Gonzalo and his team for the excellent work they are doing with my company. Their collaboration has been a springboard in the digital marketing development of the firm, without a doubt the best decision I have made. Gonzalo gets it right the first time, a great human team always attentive to what you need. 100% recommended.
Jelena Marjanovic
I met Gonzalo when I was looking for a digital marketing specialist to help me expand my Training and Development business. Gonzalo made a complete study of my business and created a short and long term strategy that enabled me to capture new clients and increase my profit. He is passionate about his work as well as my business and goals. He managed to understand my ideas and simplify them to make them practical. I felt very comfortable working with him because I could feel his primary motivation is to help people fulfill their dreams.
Julián Chappa
"The Funnel Box" not only managed to provide me with that fundamental added value, but Gonzalo Castro's professionalism, experience, and empathy allowed me to capitalize on my dream as a freelance editor. Gonzalo designed a personalized campaign, which allowed me to get my ideal target audience: Spanish-speaking authors from all over the planet. I highly recommend this service. Behind "The Funnel Box" there are flesh and blood heroes who are passionate about what they do.

Taxcom Advisors
A very professional agency that provides constant follow-up on the account. We are very happy working with them.
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.
