Did you know it can cost 30% more to use an AI model in Spanish than in English? For Hult MBA alum Germán Martínez, this wasn’t just a statistic—it was a problem to be solved. 

While the world was talking about AI, Germán noticed the conversation was largely in English. Most advanced AI models and resources are optimized for one language, creating a hidden barrier for nearly 500 million Spanish speakers. 

“Most of the technical information and how-tos are in English,” Germán explains. “These AI models are trained primarily in English. They answer a bit better in English than in other languages.” 

Germán’s solution 

Driven by the same curiosity that pushed him to understand Web 2.0 fifteen years ago, Germán began experimenting. He wanted to understand the mechanics behind the machine.   

“I think there’s a parallelism with AI,” he says, comparing it to a Formula One driver. “They’re not mechanics, but they do know how their car works.”  

To truly learn, he started sharing. He launched aprendiendoia.co (Learning AI), a Substack newsletter to explain the complexities of artificial intelligence in a simple, accessible way—as if he were “having a beer or a coffee with a friend.” 

What started as a personal learning project with just 20 subscribers became a “happy accident.” His jargon-free, honest approach resonated. In just over a year, his readership has grown to more than 9,000 subscribers, and his publication ranked as a top-10 Spanish-language tech Substack.

Hult’s impact  

This journey from a curious professional to an influential voice was shaped by his time at Hult. The Executive MBA at Hult Boston didn’t just give him a high-level understanding of business; it gave him an international lens.

“Talking with my people from Germany, Colombia, Brazil, and India, and seeing how they view the world … it broadened my perspective a lot,” he reflects. “Being part of a  global cohort helped melearn to navigate and bridge diverse cultural and business contexts.”

When the pandemic moved his final courses online, Germán took advantage of extra classes from the Master’s in Business Analytics program. Courses in Python and data science gave him the technical foundation he now uses to deconstruct how AI works. He continues to embrace lifelong learning, taking a course almost every year to stay current.

His advice for others? Develop a “passion for learning.” In a field where new models from Google, Anthropic, and OpenAI emerge weekly, the only constant is change. “You need to try to understand how the tools you’re using work,” he advises.

Germán’s work is a powerful example of the Hult mindset in action: identifying a global challenge, applying practical skills to deconstruct it, and using a multicultural perspective to build a bridge for an entire community.
