Julián Colombo, founder and CEO of N5, was this week’s guest on Poker de Damas (Radio La Plata), where he shared — with the humor and bluntness typical of radio — the real story behind one of the lines most often repeated about him: that he started with $100 and now leads a company valued at $100 million. The full interview is well worth a listen, but here’s the written recap for those who prefer reading it.
The $100 Myth
He started by clarifying something: the “$100 to $100 million” line is more of a journalistic shorthand than an exact account. What is true is that, when opening the company’s bank account in the United States, he deposited just $100 — all the cash he had on hand, since after a whole career in banking he barely carried cash anymore. That almost incidental detail ended up becoming N5’s founding legend.
Before that came 20 years of corporate career: branches, commercial steering committees, fourteen different countries, from a Banco Río branch five blocks from the radio studio to Banco Santander’s corporate headquarters in Madrid. Along the way he met, among others, Ana Botín, and developed something that would prove essential for N5: having seen, from the inside, how banking works — and fails — across more than a dozen different markets.
The Decision Wasn’t Made by a Spreadsheet
The most interesting part of the conversation wasn’t the financial detail — it was the real reason behind his resignation. Colombo spent three years flying every Sunday from São Paulo to Madrid and back every Thursday, so as not to uproot his family from Brazil while he kept building his career in Spain. It was his oldest son who, without realizing it, ended up convincing him: a school friend was lucky enough to have a dad who worked at a bank in Brazil, so he could be picked up from school every day. That childlike comment showed him something obvious he’d stopped noticing: banks existed in Brazil too. That day he decided to leave, though it took him another year to actually do it.
When he told his father and his wife the plan, both reacted the same way: with the look of someone who, having already solved every material problem, now wants to complicate their life chasing an “entrepreneur” badge. His father’s response, though, is what tipped the scale: the same drive that had built that successful career was the one now pushing him to leave it.
Eight Hours of Conversation and a $5 Million Check
The most cinematic part of the interview covers N5’s earliest days. He resigned on a Thursday in Madrid, flew to the United States to set up the company (hence the $100), and the following weekend flew to Panama for a meeting with a bank owner he’d never met. Eight hours of conversation later, he walked out with a $5 million check to build software that, at that point, didn’t even exist yet. His pitch wasn’t financial: he told the owner that one day he’d count the world’s biggest banks among his investors, but he would never again have a first client to thank in every interview. That promise, he says, he still keeps.
Why “Your Bank Is Bad” (And It’s Not the Banker’s Fault)
With the business up and running — N5 today works with more than 70 banks and fintechs across 18 countries, with 97% of its revenue coming from outside Argentina — Colombo explained in simple terms the problem the company solves: technological entropy. Most banks are “alluvial”: built up over decades of mergers and acquisitions, stacking dozens of systems that never fully integrate. While a fintech can design its product from a blank page, a traditional bank has to, as he put it, change the plane’s wings mid-flight.
He was especially blunt about the economics behind customer service: if serving a customer through a human channel costs around $7, and that same customer generates only a few dollars of monthly margin, the math simply doesn’t work. It’s not that banks don’t want more people answering calls — the economics literally don’t allow it. That’s where N5’s pitch comes in: technology that delivers “human” service — patient, thorough, intelligent — without depending entirely on people on the other end of the line. He sums it up as the democratization of empathy.
The United States, Argentina, and the Question That Always Comes Up
Asked why he founded the company in the United States instead of Argentina, he was direct: a company built under U.S. rules is worth, to an investor, several times more than the identical company incorporated in a country with weaker legal stability. It’s not a judgment about Argentina, just a description of how capital thinks. Still, he noted that Argentina was the third country subsidiary the company opened, that it has never repatriated profits abroad, and that after 25 years living outside the country, the family is considering moving back for a while.
An Argentine Anecdote, Outside of Business
Between laughs, Colombo also shared a very personal moment: his youngest daughter’s swearing of allegiance to the Argentine flag, born in Brazil, during a brief consular procedure that turned out to be far more emotional than expected. A good reminder that behind the funding rounds and banking committees, there’s still a family building its identity across five different countries.
