Welcome to Season 4 of The J Curve with me, Olga Maslikhova.

This week, I sit down with João Del Valle, co-founder and CEO of EBANX—one of Latin America’s most iconic fintech stories and a company that built one of the most expansive cross-border payment platforms in the world.

Founded in Curitiba—well outside Brazil’s traditional tech hub of São Paulo—EBANX was built for scale from day one. Its global-by-design approach quickly became a powerful competitive moat, allowing the company to expand into 29 countries, process billions in cross-border payments, and power transactions for global giants like Spotify and AliExpress.

In this episode, we talk about what it really takes to scale global infrastructure from Latin America, why complexity is a competitive advantage, and how João evolved from founder and CTO to CEO of a company backed by Advent International in one of their largest-ever tech deals.

Here’s what we cover:

• How embracing regulatory and payment complexity became core to EBANX’s GTM playbook

• What 2022–2023 taught João about discipline, cold-blooded decision-making, and founder-mode leadership

• How João leads distributed teams across the U.S., China, and Latin America

• What it means to scale sustainably without blitzscaling—and still attract a firm like Advent International

• How João thinks about long-term planning, investor alignment, and the path to liquidity

• Tactical insight on navigating cross-border regulation, local payment rails, and real-time systems like Pix and UPI

For global operators, fintech builders, and investors looking for real lessons in execution—this episode is packed with insight.

Welcome to Season 4 of The J Curve with me, Olga Maslikhova.

Last week I got to spend a few days in cidade maravilhosa—Rio de Janeiro—for Web Summit, which this year attracted over 37,000 people. The event was action-packed—both inside the venue and across the city, with an incredible lineup of side events.

It was a milestone week for The J Curve. We recorded our very first live episode on stage—a conversation I’ve been wanting to have for a long time, and the one we’re releasing today: a live interview with Mike Packer, partner at QED Investors.

QED is the legendary firm founded by Frank Rotman and Nigel Morris—the creators of Capital One and pioneers of data-driven credit long before it became mainstream. They’ve been betting on Latin America for over a decade. Their first investment in the region was Nubank, now the most valuable digital bank in the world.

Here’s what we cover:

— Why growth capital is the new frontier in LatAm

— What makes a founder truly fundable in 2025+

— AI’s real impact across QED’s portfolio

— What it really takes to IPO from LatAm

— The vertical SaaS trap—and the case for vertical AI

Welcome to Season 4 of The J Curve 🎙️

This week, I sit down with Marcelo Lutz and Roberto Biselli, the co-founders and co-CEOs of Capim—a vertical SaaS + fintech company that started as an MBA class project and is now doing $10M+ in ARR, serving thousands of dental clinics across Brazil.

Their story breaks every rule—and proves that in Latin America’s most fragmented industries, the right wedge isn’t software. It’s credit.

Instead of trying to “disrupt” dentistry with a standard SaaS tool, Marcelo and Roberto built a credit product tailor-made for the quirks of Brazilian clinics—and used it to build their way into a much bigger platform play.

Here’s what we cover:

• How Capim reached $10M+ ARR in 3 years without a traditional SaaS GTM

• Supply-side fragmentation as a feature—not a bug—for B2B marketplaces

• Understanding distribution in offline markets—without relying on paid ads

• What 70,000+ dental procedures taught Capim about underwriting and risk

• How to think about product sequencing in complex industries
