Today I'm excited to introduce you to 4dFI Capital Partners — or as we call it, 4dFI — a new initiative bringing together the worlds of traditional finance and innovative fintech.

In this episode, we're diving into three key themes reshaping global financial services:

Hidden Innovations in Emerging Markets

As Russell Weiss points out, "There's some incredible innovations happening in emerging markets, and oftentimes investors and executives in the US and Europe are sort of missing it. They're not hearing those stories. They're not getting access to that technology." We'll explore how companies like Nubank are just the beginning of a wave of groundbreaking financial solutions coming from regions outside traditional financial centers.

From Fintech to Impact Investment

In regions where traditional credit infrastructure is lacking, services like earned wage access aren't just convenient—they're transformative. Josh Liggett explains how these solutions are "where a FinTech turns from a FinTech company to also an impact investment," creating both financial returns and meaningful change in consumers' lives.

Building a Value-Add Investment Community

Beyond just providing capital, Fortify aims to create a network of experienced professionals who can offer expertise, connections, and insights to emerging market fintechs. This collaborative approach benefits everyone involved—investors gain exposure to new models, startups receive valuable guidance, and ultimately, consumers get better financial products.

I'm joined today by my partners Russell Weiss and Josh Liggett, who bring complementary skills in data science, VC deal-making, and fintech expertise to this exciting venture. Whether you're a financial industry veteran looking for new horizons or simply curious about where global fintech is heading, today's conversation offers valuable insights into the future of finance beyond traditional markets.

Let's dive in.

Beyond Borders: The 4dFI fintech investment series, Part 1

Blockchain technology continues to bridge the gap between traditional finance and the digital asset ecosystem. Today, we're witnessing a fascinating convergence where decentralized finance protocols are being integrated into user-friendly platforms, making sophisticated financial tools accessible to everyday users.

One of the most significant developments in this space is the ability to leverage crypto assets without selling them—unlocking liquidity while maintaining exposure to potential appreciation. Coinbase has recently launched a groundbreaking product that allows customers to borrow USDC against their Bitcoin holdings in under a minute, all powered by onchain lending protocols.

I'm delighted to welcome Max Branzburg, Vice President of Product at Coinbase, to discuss this innovation. As a key architect of Coinbase's product strategy, Max has been instrumental in developing solutions that make crypto utility more tangible for millions of users. Today, we'll explore how Bitcoin-backed loans represent a pivotal step in Coinbase's vision for onchain financial services, the technical infrastructure making this possible, and what this means for the future of personal finance.

In late January, Upbound Group completed its acquisition of Brigit, a leading financial health technology company. This deal brings together Upbound’s established brands like Rent-A-Center and Acima with Brigit’s digital platform that offers earned wage access, credit building products, and financial wellness tools. The combined company now serves approximately four million active customers, including Brigit’s impressive base of over one million paying subscribers.

I’m thrilled to welcome Zuben Mathews, co-founder of Brigit, to our podcast today. Zuben continues to lead the Brigit team as they now operate as a business segment within Upbound Group, alongside his co-founder Hamel Kothari.

In our conversation today, we’ll explore the strategic vision behind this acquisition, how Brigit’s technology will enhance Upbound’s existing services, and what this means for millions of Americans who have been traditionally underserved by mainstream financial institutions. We’ll also discuss how Brigit’s proprietary cash flow underwriting technology and machine learning capabilities might change the landscape for accessible financial products.

Joe Heck, CEO of Zip, joins me on the Tearsheet Podcast to discuss the evolution of alternative payment solutions in the US. Zip is a leading Buy Now, Pay Later (BNPL) company. Joe shares lessons from his 20 years of experience in consumer lending and fintech payment solutions. Heck brings insights from his previous leadership roles at Happy Money and TrueStage.

Heck’s background plays a role in his approach to financial services. Growing up in Flint, Michigan, he understands the challenges of paycheck-to-paycheck living. “There’s a consumer base largely ignored by traditional financial systems,” Heck explains. “FICO doesn’t serve them well, but they have a great ability to pay.”

Zip focuses on providing financial flexibility to these consumers. It offers structured repayment plans that don’t push them into revolving debt. According to Heck, “We win when the consumer wins. If they can’t pay us back, our model doesn’t work either.”

The Big Ideas

BNPL’s Growth Potential in the US – With only 2% of payments currently in BNPL, there is significant room for expansion compared to markets like Europe and Australia.

Financial Inclusion for Underserved Consumers – Zip is focusing on consumers who don’t fit traditional credit models but have strong repayment potential. “We provide access when and where they need it,” says Heck.

Strategic Partnerships Drive Accessibility – Integrations with Stripe and retailers like GameStop are making BNPL more available to consumers.

A More Transparent Alternative to Credit Cards – Unlike credit cards that encourage revolving debt, BNPL provides structured, predictable payments. “We’re not built in a way that traps consumers in debt,” Heck emphasizes.

The Role of Cash Flow Management in BNPL’s Future – Zip is investing in tools that help consumers manage unpredictable income streams, ensuring more repayment flexibility.

Artificial intelligence is rapidly transforming the financial landscape, creating new opportunities for innovation while reshaping consumer expectations around speed, personalization, and security. As financial institutions and businesses race to integrate AI capabilities, we're witnessing a fundamental shift in how payments are processed, how fraud is detected, and how financial services are delivered.

Today, I'm delighted to welcome Davi Strazza, President of North America at Adyen, a global financial technology platform that's at the forefront of this AI evolution. Davi leads Adyen's North American operations, where the company is leveraging artificial intelligence as a strategic growth driver through initiatives like their recently launched Uplift platform.

In our conversation today, we'll explore how Adyen is implementing AI solutions to enable hyper-personalization, enhance fraud detection, and automate complex financial processes. Davi will also share his insights on the state of real-time payments in the US and what companies need to do to make instant payments a more fundamental part of our commerce and financial system.

Investment in data is the hallmark of successful Gen AI implementations, according to Citizens’ Chief Data and Analytics Officer, Krish Swamy. 

Giving us a system wide view of how Citizens is leveraging Gen AI, Swamy joins the podcast to talk about harnessing the power of data to drive decision-making, enhance customer experiences, and navigate the complexities of digital transformation in the banking sector. 

Our conversation delves into the challenges and opportunities of building a data-driven culture within a traditional banking environment, and how Citizens is positioning itself at the forefront of financial innovation through strategic analytics initiatives.

Swamy, who also heads the firm’s Generative AI Council, shares his vision for the future of data in banking and the tangible ways Citizens is turning data insights into meaningful actions that benefit both the institution and its customers.

Across Latin America, we’re witnessing a massive shift as regions traditionally dominated by cash transactions begin embracing digital financial tools. This transition represents more than just technological adoption—it’s creating new economic opportunities, enhancing financial inclusion, and building resilience against growing cybersecurity threats.

The numbers tell a compelling story: a $448.4 billion digital payment opportunity exists across Latin America, the Caribbean, and the U.S. With nearly 12 million small retailers processing $362 billion in B2C sales — 43% still in cash —a nd 90% of B2B transactions between small retailers and suppliers handled through traditional methods, we’re looking at a financial transformation that’s just beginning.

Today, I’m joined by someone at the forefront of this transition. Walter Pimenta serves as Executive Vice President of Commercial and New Payment Flows for Mastercard Latin America, where he’s leading initiatives to expand SME acceptance solutions, scale enablement through strategic partnerships, and strengthen cross-border payment capabilities.

Walter’s team is also tackling another critical trend: the growing cybersecurity challenges facing SMEs, with recent research showing 46% of small businesses have experienced cyber-attacks, resulting in bankruptcy for nearly 1 in 5 affected companies.

The financial services industry is undergoing deep technological change. API-first architectures are creating new possibilities for integration. Digital platforms are democratizing access to investing. Artificial intelligence is personalizing wealth management. Digital-first brokerages are redefining what's possible. Global investing barriers are falling. Traditional firms are navigating complex digital transformations. And infrastructure companies are scaling to meet growing demands.

To help us understand these critical trends, we're joined by Harry Temkin, Chief Digital Officer at DriveWealth. DriveWealth is at the forefront of embedded investing technology, powering fractional trading and digital investment experiences for partners across the globe. As CDO, Harry leads the company's technology strategy and digital innovation initiatives, bringing decades of experience in financial technology.

Welcome to the Tearsheet Podcast, where we explore financial services together with an eye on technology, innovation, emerging models, and changing expectations. I'm Tearsheet's editor in chief, Zack Miller.

As digital assets mature beyond speculation into practical financial tools, forward-thinking institutions are evaluating how programmable money fits into their product strategies. For traditional banks, it's an opportunity to modernize settlement systems and explore new revenue streams. For fintechs, it's about embedding digital asset capabilities without the regulatory and technical overhead.

Today, I'm joined by Ben Milne, whose journey from founding payments innovator Dwolla to now leading Brale offers interesting insights into the evolution of financial infrastructure. At Dwolla, Ben built an API-first payments platform that helped modernize ACH transfers. Now with Brale, he's creating the infrastructure layer for compliant stablecoin issuance across multiple blockchains.

What's particularly notable about Ben's transition is how it reflects broader shifts in the financial services landscape—from renovating legacy rails to building entirely new ones. In our conversation, we'll unpack how this experience shapes Brale's approach to working with both incumbents and challengers, the strategic considerations for institutions exploring stablecoins, and what product and strategy executives should be planning for in this rapidly evolving space.

From ACH to stablecoins: Ben Milne's infrastructure evolution

While attention often focuses on developed markets, the most exciting fintech innovations are emerging where mobile technology, young digital-native populations, and gaps in traditional banking converge. These regions aren’t just adopting Western models – they’re creating entirely new paradigms that may eventually reshape global finance.

Today I’m joined by Nadia Costanzo, Director of Banking for the Middle East, Africa, and Latin America at Wise. Nadia drives Wise’s expansion across these regions by building banking relationships, securing licenses, and navigating complex regulatory frameworks.

Her background is uniquely valuable – before Wise, she worked with Kiva in Nairobi facilitating microfinance across Africa, contributed to the World Bank’s Universal Financial Access agenda, and worked directly with microfinance institutions in Paraguay.

Today, we’ll explore how fintech evolves differently across emerging markets, examine key challenges, and discuss surprising innovations where traditional banking is limited. We’ll also consider what these developments mean for established financial institutions looking to engage with these dynamic markets.

How Wise captured 25% of Brazil's cross-border market

Americans give nearly half a trillion dollars to charity each year—over 2% of GDP. Yet despite this massive scale, charitable giving remains stuck in the past, dominated by donor-advised funds marketed exclusively to the wealthy and clunky processes that make generosity harder than it should be.

Today I'm joined by Adam Nash, co-founder and CEO of Daffy, a modern platform that's democratizing charitable giving through technology. Adam brings decades of experience building consumer fintech products as the former CEO of Wealthfront and in leadership roles at LinkedIn, Dropbox, and eBay. During the pandemic, he recognized that while fintech had revolutionized how we save and invest, charitable giving had been largely untouched by innovation.

We'll explore why Adam left Wealthfront to tackle charitable giving, how Daffy's membership-based model differs from traditional approaches, and why he believes donor-advised funds will soon be as common as 401ks. Adam will share insights on tax-advantaged giving as more people hold appreciated assets like stock and crypto, how Daffy is incorporating AI, and why they've opened their APIs to partners like Betterment and Robinhood.
