What does it mean to you to be a woman building financial infrastructure for the world’s most underserved communities?
It means I get to solve problems I’ve actually lived.
Before Grey, I was the person trying to receive payments from international clients into a Nigerian bank account and watching fees eat into my earnings. I was the one refreshing my screen, hoping a client I wanted to work with wouldn’t turn me down because I didn’t have a local US account. I was the woman at a BDC doing mental math about exchange rates.
When I think about the millions of people using Grey today, I’m not imagining some abstract user persona. I’m thinking about the version of me five years ago. I’m thinking about the designer in Lagos waiting three days for a $500 payment to clear. The remote worker whose card gets declined at a hotel check-in for no apparent reason. The entrepreneurs who can’t accept payment from clients abroad without losing 10% to fees and delays.
Building infrastructure for underserved communities isn’t charity work. It’s recognizing that these communities have been underestimated, not under-qualified. The talent is there. The ambition is there. The hustle is there. What’s been missing is access, access to accounts, access to cards, access to the basic financial tools that people in developed markets take for granted.
That’s what makes our work meaningful. I’m not building for an imaginary user in a strategy deck. I’m building for people who look like me, live like me, and dream bigger than borders allow. And I get to do it as a woman, in a leadership role, at a company that started in West Africa and now serves users across over 70 countries.
That representation matters too. Every time a young woman in an emerging market sees someone who looks like her leading global marketing at a Y Combinator-backed fintech, it expands her sense of what’s possible for herself. I don’t take that lightly.
Grey has expanded from West Africa to 70+ countries in record time. What does this kind of scale teach us about what’s possible when we challenge the narrative that innovation only comes from traditional tech hubs?
To paraphrase my CEO, it teaches us that proximity to the problem is more valuable than proximity to Silicon Valley.
When you’re building from Lagos, you don’t have the luxury of theorizing about emerging market pain points in a pitch deck. You live them. Your family lives them. Your first users are people you know personally. That intimacy creates a different kind of product intuition, and it’s one that’s grounded in real frustration, not market research.
Grey didn’t start with us asking, “What fintech product can we build for Africa?” We started by asking, “Why is it so hard to get paid internationally when you live here?” The answer to that question became the product. And it turned out that freelancers in Egypt, remote workers in India, and entrepreneurs in Kenya were asking the same question. The playbook we developed in Nigeria traveled because the problem is global.
We also learned that you can build world-class infrastructure from anywhere. The limitation is not in our capability. It was opportunity and access. Our engineering team, our product team, our marketing team, I think we’ve proven that the talent in African cities can compete with anyone.
What excites me most is that Grey isn’t an anomaly. Yes, we were the first to offer multi-currency accounts in this market, but there’s a whole new generation of African fintechs that have scaled globally. The narrative that innovation requires a San Francisco address is dying. Some of the most interesting fintech infrastructure is being built in Africa and other emerging markets because that’s where the friction is most visible, and the incentive to solve it is highest. The lesson for anyone paying attention: don’t sleep on emerging markets.
Can you share a moment when your lived experience as a globally mobile woman directly shaped a decision that changed Grey’s trajectory?
I travel constantly for work, conferences, market visits, and partnership meetings across multiple continents. And for years, even while working at a fintech, I experienced the exact frustrations our users describe.
Sometimes your card declines at hotel check-ins for no apparent reason. This still happened to me in Morocco last year. Other times, it’s not being able to use Apple Pay in countries where it should work. I can’t count the number of times I’ve been standing in a new city, doing math to see if I had enough local currency, because I didn’t trust my card would go through. There’s something to be said about the low-grade anxiety of never quite knowing if your money would work when you needed it.
That lived experience kinda shapes how I think about every part of our product. When I talk about “borderless banking,” I’m really not describing a vague feature; I’m talking about being able to walk into any city in the world and know your money will just work. No contingency planning. No backup cards.
It’s why I push hard on features like our new cards that support contactless payments. Tapping to pay at literally anywhere in the world isn’t a “nice to have” feature for globally mobile users. These seemingly minor improvements are the difference between feeling like a local and feeling like a financial second-class citizen everywhere you go. The mental load of constantly converting, transferring, and timing your money across currencies is exhausting. Having USD, EUR, and GBP in one place, with instant exchange at competitive rates, removes that cognitive tax. I don’t have to imagine what our users want. I am our user, and it’s how I make decisions.
The UpGreyed Her grant program specifically supports women entrepreneurs in emerging markets. Why was it critical for Grey to make this kind of social impact investment, and what transformation have you seen so far?
The IFC estimates a $1.9 trillion financing gap for women-owned MSMEs globally. It would be a little hypocritical to build a business on the insight that traditional financial infrastructure failed people like our users and then ignore how that failure compounds for women entrepreneurs. They face everything our users face, plus additional barriers: less access to capital, fewer networks, and often less support for taking entrepreneurial risk.
I was involved in creating UpGreyed Her from the beginning, along with an amazing team of women. We launched it in 2024, and it’s now entering its third edition. We’ve funded seven women entrepreneurs with fascinating businesses across Africa and Latin America with $17,500 in grants. We’re focused on women aged 21-35 who have already established viable startups in male-dominated industries such as manufacturing, construction, and logistics, or in tech-enabled sectors such as AgriTech, ClimateTech, EdTech, and HealthTech, and want to expand.
Our 2025 grand prize winner, Patricia Zanella, runs Eco Ciclo in Brazil, a company that produces biodegradable sanitary pads for indigenous communities. Eco Ciclo has gone on to receive national recognition in Brazil, winning a Government award for Women in Science, and this year, Eco Ciclo will be the official provider of biodegradable sanitary pads for Camarote Salvador, recognized as the most sustainable carnival lounge in Brazil. Her story represents exactly what UpGreyed Her is about: a woman with vision, impact, and the ability to scale, who just needed the capital to make it happen.
For us, this isn’t charity. We think of it as an investment in the economic engine that women entrepreneurs represent. And it’s a statement about what becomes possible when women are given the backing they deserve.
Looking at the next generation of female leaders, particularly in Africa and other emerging countries, what barriers do you see that still need to be lifted?
I’d point out three structural barriers and one internal one.
One is access to capital. The financing gap is real, and it starts early. Whether it’s funding to start a business, investment to scale one, or simply the financial cushion to take a career risk, women in emerging markets are operating with tighter margins. That affects which opportunities you can say yes to. It’s hard to bet on yourself when you’re one bad month away from a financial crisis.
Two is access to rooms. So much of career progression happens through informal networks, basically who you know, who vouches for you, and who invites you into the room where decisions get made. Women, especially in emerging markets, are often locked out of those rooms. It’s not because anyone explicitly said no, but because the rooms were built by and for men over the course of decades. The introductions happen at the bar after the conference. Deals close over a hike, and mentorship happens between people who remind each other of their younger selves.
The third thing is access to models. Honestly, when you don’t see women who look like you in leadership positions, it’s harder to imagine yourself there. Representation for women isn’t just about inspiration, it’s also about information. How do you navigate a board meeting? How do you negotiate equity? How do you handle investor meetings? How do you manage a team across time zones? Women often have to figure this out with fewer role models and less institutional support.
Lastly, the internal barrier is permission. There’s still a cultural expectation in many places that women should be grateful for whatever opportunity they get, rather than actively pursuing the biggest role they can imagine. I’ve watched talented women hold back from applying for senior roles because they didn’t feel “ready enough.” Meanwhile, their male peers were applying for roles they were half-qualified for and figuring it out along the way.
What gives me hope is that more women are building their own rooms, creating their own permission structures, and finding ways to support each other financially. I believe the next generation won’t wait to be invited, and they’ll have more women ahead of them showing what’s possible.
When making strategic decisions about which markets to join or communities to serve next, what questions do you ask yourself?
I start with demand signals. Where are people already trying to use Grey even though we haven’t officially launched there? Where are we seeing organic sign-ups, social media mentions, or customer support inquiries from users who found us on their own? If people are seeking us out, that’s a strong signal that the pain point is acute.
Morocco and India both surprised us this way. We saw organic traction before we’d done any real marketing push; users were finding Grey through word of mouth, signing up, and asking when we’d fully support their country. That kind of data is worth more than any market size report.
Then I look at corridor strength. Cross-border payments aren’t just about countries; they’re also about specific money flows. Which corridors have volume? Where are people sending money to and from? A market might look attractive in isolation, but it becomes much more interesting when you see how it connects to markets we’re already strong in.
I also ask: do we have a right to win here? Is there something about Grey’s positioning, product, or team that gives us an advantage? Or are we just chasing TAM like everyone else?
And I’ve learned to say “not yet” to markets and features that don’t have direct user impact. We had pressure to launch in certain markets due to their size. Still, when we looked at our actual ability to serve those users well, thinking about support coverage, banking partner stability, and compliance infrastructure, we realized we’d be setting users up for a frustrating experience. We’re waiting until we can do it right. Nice-to-haves are not good enough. If it doesn’t solve a real problem for real users, it can wait.
Finally, I think about sequencing. Which markets unlock other markets? India was strategic not just because of its size, but also because so many Indian freelancers work for companies in the US, UK, and Europe. Serving them well creates network effects that strengthen our existing corridors.
How do you ensure Grey stays true to its mission as it grows?
By being ruthless about what actually creates value for users versus what just looks good on a roadmap.
Growth pressure can push you toward decisions that optimize for metrics over user experience. There’s always a case for launching something faster, expanding somewhere sooner, or adding a feature because competitors have it. I’ve learned to push back on “nice-to-haves” that don’t directly impact the people we serve.
We had an opportunity to launch a feature that would have looked great in a press release, but when we mapped out the actual user journey and impact, the value was marginal. It would have consumed engineering resources that would have been better spent on reducing friction in our core product experience. We said no and redirected that effort toward something users actually asked for.
Our guardrail is staying close to users. Not in an abstract “customer-centric” way, but literally. Our support team talks to users every day. Our product team reads complaints. I read DMs from users on social media. When you’re that close to the people you serve, mission drift becomes harder because you see immediately when you’re letting people down.
I also think tension is healthy. Having people in the room who will name when growth and user value are in conflict, and being willing to leave opportunity on the table sometimes, is how you stay honest.
Grey’s mission is to make globalisation work for everyone. That’s specific enough to hold ourselves accountable. Are we serving people that traditional banks won’t serve? Are our fees actually lower than the alternatives our users have access to? Are we making their lives easier or just adding another app to manage? If the answer to any of those questions starts to slip, we’ve drifted.
What does leadership look like when you’re working with communities that traditional financial institutions have overlooked?
It starts with humility.
These communities haven’t been served, but that doesn’t mean they’ve been sitting around waiting to be saved. They’ve built informal systems, workarounds, and networks to survive without access to traditional banking. Your job isn’t to arrive with a solution and impose it. It’s to understand what’s already working, what’s broken, and where technology can genuinely help versus where it would just add friction.
It also requires patience. Trust takes time when you’re working with communities like these. A big bank making promises doesn’t mean much when you’ve seen those promises broken in accounts frozen without explanation, fees hidden in fine print, and support lines that never respond. We earn trust by showing up consistently, being transparent when things go wrong, actually listening to feedback, and changing things based on what users tell us.
And it requires representation. Our team includes people from the communities we serve, and that is a strategic advantage. When your team has personally experienced the problem you’re solving, the quality of decisions they make improves. When your team understands the cultural context, the messaging lands differently, and users feel understood.
Leadership in this context also means advocacy. That means being vocal about de-risking, about KYC requirements that treat entire countries as suspicious, and about the stark difference between how to move money internationally depending on where you live.
You’ve described Grey as building for ‘the borderless generation.’ Beyond the product features, what attitude shifts are required—from users, the industry, and policymakers?
From users, we need a willingness to try alternatives and trust that better options exist. Many people stick with broken systems because they’re familiar. The mental switching cost is real. We need users to believe that trying something new isn’t as risky as it feels, and that they deserve better than what they’ve settled for.
From the industry, I’d say an end to the lazy assumption that emerging market users are “high risk” by default. Yes, compliance matters. Yes, fraud exists. But sophisticated players can serve these markets profitably and responsibly. Grey is proof of that. The industry needs to stop treating emerging market users as a problem to be managed and start seeing them as a market to be served.
From policymakers, we need recognition that cross-border economic participation is the new normal, not an edge case. Regulations were built for a world where people lived, worked, and banked in one country. That world is shrinking. The freelancer in Lagos working for a client in London and spending on a trip to Dubai isn’t an anomaly; she’s the future, and I think policy should enable these people, not treat them as suspicious. That means rethinking KYC frameworks that assume everyone has a fixed address, for example, or creating regulatory sandboxes that allow innovation without requiring years of licensing.
The borderless generation already exists. The attitude shift is recognizing that financial infrastructure needs to catch up with how people actually live.
‘Give to Gain’ emphasizes collaboration over competition. In your experience scaling Grey across continents, how significant has collaboration been with partners, communities, and even competitors to your success?
All we do is collaborate and partner. It’s how we’re able to scale and reach as many people as we can. No fintech is an island, and certainly not one trying to serve 70+ countries. We can’t have reached users in 70+ countries by building everything ourselves. Our banking partners, payment processors, and local partners in each market are part of our infrastructure.
We’ve also collaborated deeply with communities. Organizations like She Codes Africa, Moringa School, Ingressive for Good, and others have been partners in building technical literacy and creating pathways for young Africans to access global opportunities. We sponsor programs, we show up at events, and we hire from their networks where we can.
One of my favorite brand partnerships is with Airalo. As a digital nomad myself, I know the feeling of landing in a new country and needing internet immediately. Not in an hour after, but the moment the plane touches down. That partnership solves a real pain point I’ve personally experienced dozens of times. I think that’s what good collaboration looks like: two companies solving adjacent problems for the same user.
Fintech in emerging markets is still a growing pie. We spend less time worrying about taking share from each other and more time thinking about how to expand the overall market. When users trust digital financial services more, everyone benefits. When regulatory environments improve, everyone benefits. When banking partners become more comfortable with emerging-market fintechs, everyone benefits.
Over the course of your career, what unexpected gains have come from your willingness to share what you’ve learned?
More than I can count.
Speaking openly about what we’ve learned scaling Grey, including our mistakes, has built more trust than any polished case study. People reach out because they saw a talk or read something and thought, “she’s actually telling the truth, not just doing PR.”
The unexpected gain is that sharing creates a community of people who want to help you, because they believe you’d do the same for them. In an industry where everyone guards their playbook, being open about what works and what doesn’t makes you memorable. It attracts collaborators, partners, and talent who want to work with someone honest.
I’ve also found that teaching something is the best way to learn it. When I have to explain a strategy to a room full of people, I understand it more deeply myself. The articulation creates clarity.
What have you had to ‘give up’ to create space for others to rise?
Control. That’s the honest answer. And thankfully, I hate micromanaging, so this comes naturally to me. When you’re building something from an early stage, like I have, you get used to being close to every decision. Your instincts are sharp because you’ve seen every iteration. But at some point, that closeness becomes a bottleneck. If everything flows through you, you’ve capped your team’s growth and your own.
I’ve had to let go of being the person who touches every campaign, reviews every piece of copy, and sits in every meeting. Some of that work is now done by people on my team who are better at it than I was. That’s the goal, to make yourself less essential, not more.
A recent example: I realized my EA, has a genuine talent for brand activations and event execution, not just logistics, but also the creative and strategic side. Instead of keeping her in a support role, I’ve stepped back and created space for her to ideate and execute end-to-end. She’s flourished, and our event experiences are better than if I’d kept my hands all over them.
I’m also lucky to work with a fantastic internal and external team that makes this easy. When you trust your people, letting go is a relief, not a sacrifice. My motto now is: I’d rather have six people operating at full capacity than have one person (me) become a bottleneck for six functions.
The irony is that giving up control has made me more effective, not less. My job as VP isn’t to do the work, it’s to make sure the right work gets done by people who are empowered to do it well.
What message would you send to a young lady in Lagos, Manila, or Casablanca who has a world-changing idea but is unsure if she has the necessary qualifications?
Do it afraid. And if you’re honest with yourself, you’re not waiting for qualifications. You’re waiting for permission. That permission isn’t coming from anyone else; you have to give it to yourself.
I started my career at Grey with no budget, figuring things out as I went. Nobody asked for my title. They asked if I could solve the problem in front of me. Every role I’ve had since has been built on that foundation: prove you can do the work, and the title catches up later.
When I took on the challenge of rebranding to Grey and building a global brand with a team based primarily in Africa at the time, I didn’t feel ready. I wasn’t sure I had the experience. But I said yes anyway and figured it out along the way.
Let’s be real, the world is full of “qualified” people who never ship anything. Your idea, hustle, and willingness to start before you’re ready are worth more than a certificate on a wall. I’ve learned that confidence doesn’t come before action. It comes after. You take the scary step, you survive it, and then you feel ready for the next one. If you wait until you feel qualified, you’ll wait forever.
Start small. Start messy. Start now. The credentials you think you need will come from doing the work, not from waiting until you feel ready.
And find your people. The women who will cheer you on, celebrate your wins like theirs, challenge you, and remind you who you are when imposter syndrome gets loud. You don’t have to do this alone.
