How a Wall Street Trader Built a $2.2B Neobank From a Teen Debit Card
The wild story of how Stuart Sopp went from moving millions to making millions — and turned a niche “teen card” into one of America’s fastest-growing digital banks
Hey Deal Lifters 👋🔥
Today’s story is a masterclass in fintech wedges, timing, and building a product that sneaks in through the side door of a giant market.
We’re breaking down Current — a neobank now used by millions of Americans — and the journey of a founder who went from:
💼 Moving billions on Wall Street
➡️ to realizing the system was broken
➡️ to building a teen debit card
➡️ then pivoting
➡️ then riding a once-in-a-generation macro wave
➡️ to becoming a $2.2B fintech rocketship
This one has everything:
The psychology of fintech adoption
A wedge so clean it belongs in a textbook
A pivot that changed the company
A global crisis that became their biggest accelerant
A founder who bet on Gen Z before it was cool
Let’s get into it. ⚡📱

🧨 PART 1 — The Origin Story: A Wall Street Trader Who Saw Broken Systems
Before Current became one of America’s leading neobanks, its founder Stuart Sopp spent almost two decades on Wall Street.
Morgan Stanley.
Citi.
Top-tier trading floors.
But here’s the twist:
The more money he moved, the more obvious it became…
The financial system wasn’t built for normal people.
Not even close.
It was built for:
big institutions
high-net-worth clients
internal efficiency
Not for:
teenagers
gig workers
hourly earners
people living paycheck-to-paycheck
Stuart watched:
overdraft fees destroy people
slow ACH transfers screw up bills
banks profit off late fees
young people have zero financial education
and banks ignoring mobile-first users entirely
And he realized something big:
The system wasn’t outdated by mistake.
It was outdated by design.
If you’re rich, the financial system works great.
If you’re not… it extracts.
Stuart believed the world needed a bank that worked like the apps his daughter used:
Fast.
Transparent.
Mobile-native.
Zero BS.
But he knew entering banking head-on was suicide.
Neobanks die when they try to be “the everything bank” on day one.
So he needed a wedge.
A Trojan horse.
A small door that opens a big market.
He found it.
And it’s brilliant.

🧒 PART 2 — 2015: The Teen Debit Card Wedge
Here’s the move:
Instead of trying to become a bank for everyone…
Stuart launched a debit card for teens.
A product banks ignored.
A segment no one cared about.
A demographic too young to be profitable.
But that’s exactly why it worked.
Teen banking was:
underserved
ignored
culturally huge
and virality-friendly (parents share, teens share, influencers share)
Parents loved it because:
they could track spending
set allowances
control limits
prevent cash leaks
Teens loved it because:
it gave them financial autonomy
it felt like a “real” bank
it looked cool
the app was smooth and modern
And best of all:
Gen Z doesn’t use checks.
They don’t walk into branches.
They don’t care about incumbents.
Stuart built Current as a debit card product…
…but secretly used the years to build full-blown financial infrastructure under the hood.
A sleeping giant.
🔥 PART 3 — 2017: Influencers, TikTok Energy, and Organic Growth
Current didn’t spend on billboards.
It didn’t buy TV ads.
It didn’t fight big banks head-on.
Instead:
It grew through influencers, creators, and parents sharing it.
This was early TikTok / early YouTube finance era.
Creators like:
teen vloggers
parenting accounts
“money tips” influencers
…all started talking about Current, organically.
Gen Z spreads fast.
And banking products never spread through this channel.
This was one of the first banks to go viral the way consumer apps do.
Stuart had found a wedge with distribution built-in.
🚀 PART 4 — 2019: The Grand Pivot (Teen Banking → Neobank for Everyone)
By 2019, Current had traction.
But here’s where Stuart made his big founder call:
Teen banking was a wedge. Not the destination.
If Current stayed there, it would top out at maybe a few million revenue.
But the infrastructure they built?
🔥 Core banking
🔥 Fraud systems
🔥 Compliance rails
🔥 App UX
🔥 Instant notifications
🔥 Deposit management
This was enough to build a real bank.
So they pivoted.
From:
“Banking for teens.”
To:
“Banking for everyone banks forgot.”
They launched:
no overdraft fees
instant spending notifications
early direct deposit
slick UI
mobile-first everything
It was everything legacy banks refused to offer.
This was the Chime playbook — but with better UX and a stronger cultural brand.
💸 PART 5 — 2020: The Pandemic Hypergrowth Explosion
This is where the story gets insane.
When COVID hit:
millions lost jobs
stimulus checks rolled out
people needed fast access to money
traditional banks were stuck in molasses
branches were closed
ACH transfers took days
Meanwhile, Current offered:
⚡ Early access to stimulus checks
⚡ Zero-fee banking
⚡ Fast deposits
⚡ No overdraft fees
⚡ UI that felt like TikTok
The result?
Current went from 200,000 → 2,000,000 users…
IN 12 MONTHS.
That kind of hockey stick is basically unheard of in banking.
This wasn’t luck.
This was:
Perfect timing
A perfect wedge
A perfectly built infrastructure layer
A brand Gen Z already trusted
Most banks weren’t ready.
Current was.
🦄 PART 6 — 2021: The $2.2B Unicorn Moment
In 2021, Current raised a $220M Series D led by a16z.
Valuation: $2.2 billion.
Status: Unicorn.
This validated everything Stuart believed:
Banking is broken
Gen Z wants mobile-first money
Incumbents don’t innovate
The future is software, not branches
This made Current one of the fastest-growing digital banks in America.
Only Chime and Cash App were ahead — and even then, not by much.
📱 PART 7 — Today: The Gen Z Banking Battlefield
As of today, Current sits in a competitive warzone:
Chime
Cash App
Venmo
Dave
Step
Traditional banks waking up
But the thing Current did differently is this:
It built culture, not just banking.
Current’s identity is:
no BS
no fees
fast money
built for people who don’t get financial respect
Stuart built a bank for:
gig workers
younger users
those living paycheck-to-paycheck
people burned by traditional banks
people who prefer push notifications over phone calls
This is a massive market.
And once you own the customer relationship — deposits, spending, cash flow — you can build ANYTHING on top:
lending
investing
crypto
credit building
rewards
BNPL
high-yield accounts
Current is slowly becoming a full financial stack for younger America.

🎯 PART 8 — The Strategy Breakdown (Why Current Worked)
Let’s zoom out.
Here’s the 4-step playbook Stuart executed perfectly:
1️⃣ Wedge Into a Giant Market Through a Tiny Door
Teen banking → mass-market banking.
2️⃣ Build Infrastructure Before You Need It
Most neobanks are wrappers on someone else’s system.
Current built its own rails.
3️⃣ Ride Macro Tailwinds Like a Pro
Stimulus checks + remote work + digital banking boom = perfect timing.
4️⃣ Brand > Features
Current’s brand matters more than its tech.
Gen Z wants:
speed
transparency
fairness
That’s not a feature list.
That’s a feeling.
And Current nailed it.
🧠 PART 9 — Founder Psychology: Why Stuart Sopp Won
Stuart isn’t a typical founder.
He isn’t a hoodie-wearing 22-year-old hacker.
He isn’t a former FAANG engineer.
He isn’t a VC darling.
He’s a guy who:
spent 20 years watching finance from the inside
saw how the system actually works
understood incentives
understood the pipes
understood where banks make money
and where they screw customers
This combination is rare.
Most fintech founders come from tech.
Few come from actual banking infrastructure.
That’s why Current scaled:
Stuart built it with real-world banking logic.
🧩 Deal Lift Takeaway
This story is a blueprint for anyone attacking a giant market.
If you want to disrupt a big category…
don’t go straight at it.
Find the wedge.
Enter through the side door.
Build trust.
Collect users.
Build infrastructure quietly.
Then flip the switch.
Current’s wedge?
Teen banking.
Its destination?
A full neobank for millions of Americans.
If you want to beat giants, start small.
If you want to win markets, pick one customer first.
Because in business:
👉 You can’t be everything to everyone on day one.
👉 But you CAN be everything to everyone someday.
