The Geometry of Fintech
The Geometry of Fintech
I was never great at math.
I stumbled through algebra, barely survived trigonometry, and in 1990, I found the beats and lyrics of Public Enemy’s Fear of a Black Planet far more interesting than anything I’d find in a math textbook.
But in 10th grade, something clicked: geometry.
It was the first math class I ever aced.
Not because I suddenly loved numbers, but because geometry wasn’t about memorizing formulas. It was about logic. If A is true, and B follows from A, then C isn’t optional. You don’t argue with it. You accept it and move on.
That way of thinking stuck with me. It probably explains why I later found statistics easier than long division, and why I’m instinctively drawn to systems that reveal their structure once you look at them from the right angle.
That geometry lesson came back to me earlier this month, not in a classroom, but on a stage in Amsterdam.
An onstage moment
I was moderating a panel at the ABN AMRO + Techstars Future of Finance Accelerator Demo Day, immediately after a keynote by David Birch. Dave made a statement that stopped me in my tracks:
“AI will become the dominant user of stablecoins.”
At first glance, that sounds provocative. Maybe even theoretical.
But the more I sat with it - especially while watching nine finely tuned fintech pitches back-to-back - the more it started to feel… inevitable.
Earlier in the discussion, I’d said something fairly standard: that stablecoins solve real problems in emerging markets - you can’t trust banks, you can’t trust governments, you can’t trust your currency - but those problems don’t really exist in developed markets.
Dave pushed back.
He didn’t fully finish the thought, but he didn’t need to. Earlier in his talk, he’d dropped another stat that stayed with me:
£292 billion sitting in UK current accounts earning nothing.
That’s not a technology problem.
That’s not a regulatory problem.
That’s a trust problem.
Trust didn’t disappear - it got quieter
In emerging markets, trust failures are loud and visible: inflation, capital controls, bank collapses.
In developed markets, trust failures are quieter - but no less real.
Money sitting idle because inertia is profitable for banks.
Insurance priced opaquely because customers don’t switch often enough.
Financial products designed around friction, not outcomes.
We tolerate it because switching is hard, optimization is time-consuming, and the systems are stacked against individuals paying attention.
But an AI agent won’t tolerate that.
AI doesn’t care about bank brands.
It doesn’t care about legacy relationships.
It doesn’t care that “this is how it’s always worked.”
If you tell your AI agent to optimise your finances - savings, payments, insurance, subscriptions - it will do exactly that. Continuously. Relentlessly.
And crucially: it won’t wait for banks to open on Monday morning.
Why stablecoins matter more in developed markets than we think
This is where the geometry snapped into place for me.
If AI agents are going to move money around on your behalf - reallocating, rebalancing, settling, optimizing - they need rails that are:
programmable
instant
available 24/7
cheap
deterministic
permissionable via code, not paperwork
That’s not fiat money.
That’s not SWIFT.
That’s not batch settlement.
That’s stablecoins.
On stage, I said something that landed more strongly than I expected:
AI agents are the only ones in the room who treat crypto like a grown-up.
Humans argue about narratives.
AI cares about execution.
And once you see stablecoins as machine money, not consumer money, a lot of things suddenly make sense.
Lex Sokolin recently called stablecoins “robot money.”
It’s a great phrase, because robots don’t need brands, branches, or business hours. They need reliable, programmable settlement.
The quiet implication for fintech
Sitting through those pitches in Amsterdam, I had a realization that’s still reshaping how I think about fintech:
If AI becomes the dominant user of stablecoins, every fintech product will need onchain settlement.
Not because crypto “won.”
Not because regulation collapsed.
But because optimization demands it.
We’re heading toward a distinction that will matter a lot:
Offchain fintech: beautiful UX wrapped around slow, permissioned rails
Adaptive fintech: products designed to plug into onchain settlement when needed
Onchain fintech: systems built natively for programmable money, AI agents, and continuous optimisation
Stripe sees this clearly. Their acquisitions - Bridge, Privy, Metronome - aren’t a crypto strategy. They’re an infrastructure strategy. They’re building the plumbing that lets money behave like software.
For a fund like Norio Ventures, this doesn’t mean chasing the next Stripe-sized outcome. It means backing the smaller, sharper teams building the connective tissue - the ramps, abstractions, orchestration layers - that let institutions and fintechs move onchain without blowing themselves up.
If all of finance is moving onchain, fintech will too.
Geometry doesn’t care whether we like the conclusion.
Where this leaves me
Most major financial innovations have historically been institution-led: credit cards, electronic trading, derivatives.
Crypto flipped that - it started with individuals.
Now AI accelerates the shift again.
Customers will move first.
Machines will move faster.
Institutions will meet them there - or become background infrastructure.
That’s not ideology.
That’s geometry.
A companion conversation
As I was processing all of this, I recorded this week’s episode of MoneyNeverSleeps with Garrett Cassidy.
We didn’t explicitly call it “the geometry of fintech,” but we circled it from multiple angles - stablecoins, AI agents, geopolitics, dollar dominance, and why programmable money changes who actually holds power in the system.
It’s a good companion piece if you want to hear this thinking unfold in real time.

If this way of thinking resonates, you can follow along here.
I’ll be writing more regularly - not show notes, but reflections like this - with Part II of The Geometry of Fintech coming next.
MoneyNeverSleeps has also entered a new era: shorter, sharper conversations, video-first on YouTube, and a fully reorganized back catalog into themed playlists, giving listeners a new way to explore the first 300 episodes.
And if you’re building - particularly in adaptive or onchain fintech - I’m always happy to hear from founders thinking along these lines.
