Ayo explains that Cash App’s success came from a stack of disciplines—clear differentiation, small senior teams, strong design, and deep understanding of regulation and infrastructure—rather than a single silver bullet. He shares practical frameworks for product differentiation, how to run a true “startup within a startup,” and why he intentionally hires ex-founders despite the challenges.

Key Takeaways
Differentiation must be both different and better in a way that matters.
Ayo argues that simply being different is trivial, and being “better” but more expensive isn’t enough; winning products are different and better in a dimension the end user deeply values (e. ...

Compound advantages beat single “silver bullets.”
Cash App’s outcome came from many things done well—talent density, design excellence, fraud competence, consumer-first tradeoffs, regulatory depth, and organizational firewalls from the core business—rather than one magic feature.

Small, senior, tightly knit teams outperform bloated internal startups.
The early Cash App team was ~11–12 people for a long time, with high trust and experience; they achieved real scale before large headcount, avoiding the “startup within a startup” trap where team size grows faster than validated value.

In regulated, complex domains, someone must truly go to the bottom of the problem.
Whether it was physically touring card factories and testing thousands of combinations for Cash Card, or dissecting database fields and regulations at Carbon, Ayo insists that an execution owner must understand details end-to-end rather than accept shallow “expert” answers.

Intentionally hiring founders can dramatically raise output—but also churn and friction.
Ex-founders bring bias to action, depth, and bullshit detection, but they quickly spot waste, challenge the organization, and often leave after ~2–2. ...

Great hiring is long-game: you pick the people; they pick when.
Ayo treats hiring as ongoing relationship-building—meeting people early, adding value to their goals, and staying in touch so that when timing aligns, they’re eager to work together, instead of relying only on job postings and inbound résumés.

Health-tech success often hinges more on networks and crisp use cases than pure merit.
In healthcare, access to decision-makers at payers and large institutions is highly network-dependent; founders need sharply defined use cases and intros to the right buyers, or a strong direct-to-consumer wedge like Carbon Health to bypass institutional gatekeepers.

... Cash App as a team, we really cared about what we could do that was different and better than what else existed in market. Being different is not enough 'cause it's very easy to build a thing that's different from what exists today 'cause you just have to look at what exists today and build something else. Being better is not enough because it's also easy to say, "Hey, I'm going to make this thing better and just charge you more money for it." (laughs) It has to be better than what exists today in a way that matters to the end user. And for us, for a long time, it was. When someone says, "Hey, why are you better than Venmo?" I'll be like, "Try and send me a dollar that I can use now." And there's only one app you can do it with.
(instrumental music) Welcome to Lenny's Podcast, where I interview world-class product leaders and growth experts to learn from their hard-won experiences building and growing today's most successful products. Today my guest is Ayo Omodola. Ayo co-created and scaled Square's popular Cash Card alongside the hugely popular Cash App. He's currently chief product officer at Carbon Health, one of the biggest and fastest growing health tech companies in the world. He's a former founder. He's on the board of Pinwheel, and he's an angel investor in companies like Mercury Bank, Fair, Modern Treasury, and dozens of other startups. In today's episode, we dig into lessons from building and scaling the Cash Card and the Cash App, the importance of differentiation when you're building a consumer product or any sort of product, how to successfully build a startup within a startup, how to succeed in both fintech and in health tech, plus my favorite part of the conversation, a handful of incredibly insightful and practical principles and philosophies around hiring, team building, leadership, and going deep on problems. Ayo is such a fascinating human and leader, and I am excited for you to learn from him. With that, I bring you Ayo Omodola after a short word from our sponsors.
