Latin America is the third-largest fintech and payments market in the world — bigger than India, behind only the US and China. Gastón Irigoyen is Co-Founder and CEO of Pomelo, the fintech infrastructure company powering card issuing and processing for banks, fintechs, and global enterprises across eight markets including Brazil, Mexico, Argentina, Colombia, Chile, Peru, Puerto Rico, and Panama. Pomelo is backed by Index Ventures, Insight Partners, Kaszek, Monashees, and most recently Adams Street Partners in their first-ever Latin American investment.

In this episode of The J Curve, Gastón unpacks the contrarian playbook behind Pomelo: why the team went regional from day zero on a $10M seed round instead of nailing one market first, how they built a "plug and play" hiring engine that's stayed at 90%+ since founding, why they tripled revenue without adding headcount, and what it actually takes to win enterprise customers like BBVA, Santander, Bci, Bancolombia, Binance, and Bybit when nobody trusts an infrastructure startup. He also shares the Series B-to-Series C lessons most founders never document — including the end-of-year memo that turned rejections into investor trust — and his framework for the AI transformation a five-year-old company is now being forced to run.

This is a masterclass on regional-by-design strategy, B2B fintech go-to-market, founder-led fundraising in down markets, and building world-class companies from Latin America for the world.

Paulo Passoni, Managing Partner at Valor Capital, and Olga Maslikhova break down Claude 4.6, Brex’s $5.15B sale to Capital One, and why only 4 US companies can IPO right now. This is the April 2026 edition of TJC Debrief — a monthly show covering tech, venture, and capital markets for Latin American founders and investors.

We cover why Claude 4.6 was a bigger “aha moment” than the original ChatGPT for building companies and how it’s rewiring CTO roles, org design, and the question of what a moat even is anymore, how Nubank, Revolut, Tether, and Plata are reshaping consumer finance and why Paulo thinks regional US banks are an “aberration” that shouldn’t legally exist, the Brex x Capital One deal, Ramp’s software multiple, and what the prof stack saving late-stage LPs means for every fintech exit going forward, Brazil’s IPO window cracking open and Mexico’s sudden flood of Sequoia, Founders Fund, and a16z capital, why Paulo thinks many employees are already “worse than AI” and why every salary should now come with a token budget, how he built a working marketplace in three hours on Perplexity Comet without writing a line of code, and the coming collapse of low-ROI universities and what it means for talent in LATAM.

Pedro Conrade is the founder of Neon — a $1B run-rate Brazilian neobank that serves millions of underbanked Brazilians and has raised $924M from General Atlantic, BBVA, BlackRock, and PayPal. In this TJC Originals episode, Pedro shares how he survived the 72-hour crisis that almost killed Neon in 2018, how engagement data beats credit scoring, and the fundraising playbook behind a decade of capital efficiency.

We cover how to build a profitable neobank in an emerging market and why serving the underbanked is a better business than it looks, why engagement data beats credit scoring and what that means for fintech underwriting at scale, the 72-hour crisis that almost ended Neon and the real-time decisions Pedro made to save it, how Neon uses AI agents to handle collections, compliance, and customer support and what that means for headcount at scale, the fundraising playbook behind $924M raised from General Atlantic, BBVA, BlackRock, and PayPal, and why M&A destroys more value than it creates — and when it actually makes sense for a startup.

Pedro also shares why the constraints of serving Brazil’s underbanked population made efficiency non-negotiable, and why that same constraint became Neon’s most durable advantage.

Stelleo Tolda co-founded MercadoLibre in 1999 and ran Brazil for 25 years — building the $100B company into Latin America’s most valuable publicly traded business. In this TJC Operators series premiere, Stelleo unpacks how MercadoLibre outlasted 80 competitors, declared war on Amazon, scaled logistics from 8% to 95% in-house, and architected a three-year succession that actually stuck.

We cover how MercadoLibre outlasted 80 competitors while charging the highest fees in the market, the dot-com crash survival playbook and what scarcity forces you to do right, why MercadoLibre declared war on Amazon and what happened in that war room, the 2010 technology bet of throwing away everything and rebuilding from scratch, the adjacency principle that turned one marketplace into payments, logistics, credit, and advertising, why MercadoLibre chose to build versus buy at every inflection point, investing in logistics CapEx as a public company and how to bring Wall Street along, the Champions League analogy for competing against the world’s best, how MercadoLibre codified its culture at scale, the succession playbook from advisor to board member to gone, what great board members actually do, and why scarcity makes Latin America’s builders better in the age of AI.

Stelleo also shares why the worst thing for an entrepreneur is abundance — and why the next generation of iconic Latin American companies is being built right now.

Hernan Kazah is Co-Founder and Managing Partner at Kaszek Ventures — Latin America’s largest venture firm, backing Nubank, Kavak, Gympass (Wellhub), and 100+ other LATAM companies. He previously co-founded MercadoLibre, now a $100B public company. In this Season 5 premiere, Hernan shares how Kaszek evaluates founders, why the default outcome in venture is failure, the venture power law behind generational returns, and how AI is reshaping the future of software in LATAM.

We cover the early strategic decisions that allowed MercadoLibre to win, why the default outcome for founders is failure, how Kaszek evaluates founders and investment opportunities, the venture capital power law and why investors must be right only a few times, what it takes to build a generational venture capital institution in Latin America, the impact of AI on software and the future of SaaS, how great founders actually get identified, and the evolution of the Latin American tech ecosystem.

Hernan also explains why building a startup in Latin America is like “climbing Everest on top of a rollercoaster” — and why the next generation of iconic companies is still ahead.

Paulo Passoni is Managing Partner at Valor Capital — one of the most active crossover investors in Latin America, with positions in Nubank, Plata, CloudWalk, and dozens of public tech companies globally. This is round two with Paulo, following the most-played episode in J Curve history.

We cover why speed is the last real moat in the age of AI, why Anthropic may be a safer bet than OpenAI, the hiring rule at Perplexity that sounds insane until you understand what it unlocks, the 10,000-year clock Jeff Bezos is building inside a mountain and the founder mindset behind it, how capital markets are pricing Ramp vs. CloudWalk at radically different multiples despite similar revenue scale, why the Mag 7 (Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia, and Tesla) now sit at the center of global power dynamics, why LPs and capital allocators remain split on LATAM and what each side is optimizing for, and what it means to be deliberately more human in the age of AI.

In this conversation, Dileep and Bruno break down why Brazil went from six $100M ARR companies to thirty in a few years, whether AI is killing SaaS, why growth investors underwrite M&A more seriously than IPOs right now, and what “right to win” means before any LATAM founder goes global. Toward the end, Olga brings in questions from the live audience in the room during the recording.

This is the episode to send to your co-founder, your board, and the WhatsApp group where everyone is not fundraising just yet.

Recorded live at Digital Assets Conference 2025 in São Paulo, this panel covers the real bottleneck to mainstream crypto adoption, why Latin America’s volatility is creating a global edge, why public markets are suddenly hungry for digital-asset IPOs, and how stablecoins and tokenization are reshaping reserve assets.

We cover the real bottleneck to mainstream adoption — the factor slowing growth more than technology, liquidity, or regulation, the emerging-market advantage and why Latin America’s volatility and innovation pressure are creating a global edge, the new IPO class and why public markets are suddenly hungry for digital-asset companies, lessons from the last crypto cycle on the mindset founders and investors need to navigate hype and downturns, the future of digital money and how reserve assets, tokenization, stablecoins, and macro shifts will shape global adoption, and the everyday impact of how new financial primitives are already reducing friction in ordinary transactions.
