David Vélez, Co-founder & CEO @ Nubank · São Paulo
David saw how traditional banks in Brazil charged high fees and excluded millions. He built Nubank as a mobile-first, fee-free credit card and account. He had to communicate this radical simplicity to customers who didn't trust banks and regulators who were used to traditional models.
Start by naming the pressure: market timing, customer trust, fundraising, regulation, hiring, product clarity, or international expansion. Good business English starts with the audience and the stakes.
Look for the phrase or register shift that made the message clearer. Founders often move from vague ambition to specific proof, from technical detail to customer value, or from defensive language to accountable language.
Rewrite the same situation for your own work. Keep the structure, change the company, audience, and outcome, then rehearse the message with Alex until it sounds natural.
You are David Vélez meeting with central bank officials who are concerned about consumer protection and systemic risk in a no-branch model.
“We believe technology can increase both inclusion and oversight. Let me show you exactly how our data and controls give you more visibility than a network of branches ever could.”
This story is useful because it shows how founder communication changes as the audience changes. A message that works for an internal team often needs more proof for investors, more empathy for customers, more precision for regulators, and more simplicity for a public audience. That is the heart of advanced business English: not sounding more complicated, but matching the message to the listener.
When you study Nubank, pay attention to how credibility is built. Strong founder language usually combines a clear problem, a concrete decision, and a visible result. Instead of saying a product is innovative, the speaker explains what was hard, what changed, and why the change mattered to users or the market.
Use this page as a speaking drill. Summarize the founder's challenge in thirty seconds, then explain the business pivot in one minute, then practice a professional version for a meeting or interview. The goal is to make the same story sound clear in different registers: casual conversation, team update, investor answer, and executive summary.
First, write a plain-English summary of the story in four sentences: who the founder is, what problem the company faced, what decision mattered, and what changed after that decision. Keep the summary concrete. Avoid vague words like innovative, disruptive, or world-class unless you can explain what they mean in the story.
Second, turn the summary into a workplace answer. If you are practicing for an interview, connect the story to a skill such as prioritization, resilience, customer empathy, technical clarity, or cross-cultural communication. If you are practicing for a founder pitch, connect it to market timing, product trust, distribution, or execution.
Third, rehearse a short response and a long response. The short response should take about thirty seconds and sound natural in a meeting. The long response should take about two minutes and include context, tension, decision, and result. This trains you to expand or compress your English depending on the audience.
Finally, ask Alex to challenge the answer. A useful coach prompt is: "Act as a skeptical interviewer or investor. Ask me three follow-up questions about this story, then correct my answer for grammar, clarity, and register." That turns passive reading into active speaking practice.
"The challenge was not only X, it was also Y. The team had to prove Z before the market would trust them." This structure helps you explain complexity without losing the listener.
In casual speech, you can say "they had to make people trust it." In professional English, say "they had to build market trust through clearer proof, simpler messaging, and consistent execution."
Use these questions to turn the story into active business English practice. Answer each one once in writing and once out loud. The written version helps you choose precise vocabulary. The spoken version helps you build fluency and confidence.
A strong two-minute answer starts with context, not biography. You might begin: "David Vélez is useful to study because the story shows how communication changes when a company needs trust, not just attention." Then explain the business situation in one or two sentences before moving to the decision.
The middle of the answer should name the tension. For example, a founder may need to make a technical system sound simple, make an ambitious vision sound credible, or make a risky decision sound responsible. This is where many English learners get vague. Use concrete nouns like customer trust, payment reliability, product clarity, market timing, onboarding friction, distribution, or execution.
The final part should connect the story to your own professional communication. You can say, "The lesson for me is that clear English is not only correct grammar. It is the ability to reduce uncertainty for the person listening." This kind of sentence works in interviews, founder conversations, leadership meetings, and networking calls because it turns the story into a transferable insight.
After you practice the two-minute version, compress it into a thirty-second version. Keep only the founder, the challenge, the decision, and the communication lesson. This compression exercise is valuable because real workplace conversations rarely give you unlimited time. Good business English helps you choose what matters first.
