Rebuilding the Warp Core
Happy Monday, Fintech Nerds!
And happy December, somehow. For those of you who celebrate Thanksgiving (or if you just had the opportunity to spend a little time this weekend with friends or family), I hope it was enjoyable.
My long weekend was jam-packed. We hosted Thanksgiving (the men in my family took a keen interest in my turkey carving skills … which could use some work, TBH). We went into the mountains to cut down a Christmas tree (my axe chopping skills, on the other hand, are excellent). And we celebrated a birthday (which is a practice we take extremely seriously in my family).
This month will be a bit slower, content-wise, as we head towards more holidays and the beginning of a new year. However, that means I’ll have more space for fun content experiments, which is always enjoyable. The Fintech Takes podcast, in particular, will be trying out a couple of new things.
Now, let’s get to the news!

3 FINTECH NEWS STORIES
#1: Rebuilding the Warp CoreCopy anchor linkCopied
What happened?Copy anchor linkCopied
Green Dot is being chopped up and sold:
Under the deal, private equity firm Smith Ventures will pay $690 million in cash to acquire and privatise Green Dot’s non-bank financial technology business assets and operations, running them as an independent and fintech and embedded finance company.
Meanwhile, the parent company of Alabama-based lender CommerceOne will buy Green Dot Bank and its associated assets and operations and create a new publicly traded bank holding company comprising both firms.
Then, the two entities will enter a seven-year commercial relationship that will see the new bank holding company serve as the exclusive bank sponsor for the fintech’s platform.
So what?Copy anchor linkCopied
This Green Dot news reveals a fundamental tension sitting at the heart of every BaaS bank that has attempted to build out its own embedded finance tech stack.
The fintech side of the business wants to move fast, experiment, sign partners, and scale. The bank side wants to manage risk, satisfy regulators, and protect capital. Those two organisms operate at different cadences, with different risk tolerances, and are valued by investors (particularly public market investors) in completely different ways.
And yet, they need each other.
An embedded finance platform without a bank partner has no engine. A small bank without a strong fintech distribution channel has no propulsion. I’ve compared the relationship to a warp core: a controlled matter/antimatter reaction. The two forces can’t fully occupy the same space. But when they’re aligned — held close, in balance — they generate enormous power.
Green Dot never managed to achieve that balance.
Since acquiring Bonneville Bancorp in 2011, the company has lived in an awkward middle zone: too fintech-y to operate like a traditional bank, too bank-regulated to innovate like a real embedded finance platform. The result was predictable — slowing growth, regulatory setbacks, inconsistent execution, frustrated partners, and a stock price that reflected all of that.
Enter Bill Smith.
Smith is a serial entrepreneur who founded Insight Card Services — a prepaid, underbanked-focused card program that Green Dot acquired in 2014. In 2017, he founded Smith Ventures, a private equity firm. And through Smith Ventures, Smith became a founding investor and board member at, you guessed it, CommerceOne Bank.
Smith Ventures is acquiring Green Dot’s fintech platform: the BaaS relationships, the embedded finance tech stack, and the program-management capabilities. CommerceOne, meanwhile, is acquiring Green Dot Bank and forming a new publicly traded bank holding company.
It’s Bill Smith, all the way down!
And it’s a smart strategy. Smith is separating the matter and the antimatter — but keeping them in precisely the right proximity. The two entities he influences won’t be under the same roof, but they will be bound by a seven-year exclusive issuing-bank agreement. CommerceOne Bank becomes the regulated engine. Smith Ventures’ fintech platform becomes the distribution and innovation layer. Each gets its own leadership, its own incentives, its own balance sheet, and its own regulatory expectations.
But strategically? They remain tightly coupled.
Green Dot tried to integrate the whole stack, believing synergy required control. But synergy in BaaS doesn’t come from control — it comes from alignment, and alignment is often much easier when the bank and fintech sides don’t have to contort themselves into a single corporate organism.
#2: Agentic AI for Accounts Receivable AutomationCopy anchor linkCopied
What happened?Copy anchor linkCopied
A start-up just emerged from stealth after raising a Series A:
Andreessen Horowitz has led a $29.5 million Series A funding round for Stuut Technologies, an AI order-to-cash platform based in New York.
The company says the proceeds from its Series A will be used to "accelerate product development and expand Stuut's autonomous AR capabilities for mid-market and enterprise companies".
This includes a focus on advancing tools for collections, payments, cash application, deductions, credits, and disputes, targeting industries across manufacturing, distribution, consumer packaged goods, logistics, outsourced services, and medical devices.
So what?Copy anchor linkCopied
I think accounts receivable automation is the agentic AI use case I find most alluring.
(Editor’s Note — I apologize for that sentence, but I love alliteration.)
In agentic AI, the ideal use case: A.) Involves a lot of manual work that is resistant to simpler forms of technological automation, B.) Directly generates revenue for the business, and C.) Is reasonably fault-tolerant, particularly from a compliance risk perspective.
That combination is very difficult to find.
There is a lot of manual back-office work out there, just begging to be automated. However, very little of it can be directly tied to revenue generation. Typically, the value of automating those tasks is efficiency and cost savings, which is nice, but less motivating to executives evaluating business cases to invest in. And usually, anything that directly generates revenue is very fault-intolerant, especially if it’s a B2C use case, which is rife with compliance risk.
Accounts receivable (AR) is a rare exception. It’s a highly manual process that requires parsing a lot of unstructured data and facilitating a lot of synchronous and asynchronous communications with customers (all things that LLMs are very good at helping with). It directly generates revenue (the more invoices that a company successfully closes, the more revenue it collects). And, because it’s B2B rather than B2C, it has a relatively high fault tolerance.
It’s basically loan servicing and collections (which is a killer spot to plug LLMs into, as I have written about previously) without the compliance risk.
A couple of months ago, Simon Taylor and I talked about a different start-up (Lunos AI) that is going after this same problem, and I can’t say I’m surprised to see that the category is starting to get crowded.
The next thing someone (Ramp, maybe?) needs to build is the protocol to govern how AR AI Agents talk to AP AI Agents. Then we’ll be cooking with gas.
#3: Stablecoin StuffCopy anchor linkCopied
What happened?Copy anchor linkCopied
The hype train keeps rolling!
Among those hopping on board are U.S. Bank:
U.S. Bank has begun testing custom stablecoin issuance on the Stellar blockchain, marking one of the most progressive moves yet by a major U.S. financial institution toward programmable digital money.
Mike Villano, Senior Vice President and Head of Digital Asset Products at U.S. Bank, emphasized that safety and control are non-negotiable when bringing tokenized assets into the banking environment.
“For bank customers, we have to think about protections around know-your-customer, the ability to unwind transactions, the ability to claw back transactions,” Villano said.
Cross River Bank … today announced the launch of its offering to power stablecoin payments*. Integrated directly with Cross River’s real-time core, COS, the offering unifies fiat and stablecoin flows through a single, interoperable system--enabling companies to move value across chains and traditional rails, leveraging bank-grade compliance.
While today’s money movement is fragmented across fiat rails and blockchains, Cross River unifies it all—eliminating operational sprawl and the need to pre-fund or rebuild ledgers. The offering gives fintechs, enterprises, and crypto-native players a compliant infrastructure for network settlement, merchant payouts, on/off ramps, and treasury management.
And Klarna:
The Swedish “buy now, pay later” lender said on Tuesday it had launched KlarnaUSD on a blockchain created by payment company Stripe and would use the digital token for international payments.
Klarna said the stablecoin would allow it to “dramatically reduce costs for both consumers and merchants”. One person familiar with the plans said it would reduce the costs for Klarna when moving large amounts of money globally by cutting out parties such as the Swift network.
While the launch was likely to help with Klarna’s internal payment infrastructure initially, it was expected to be rolled out for merchants and consumer payments eventually, the person added.
So what?Copy anchor linkCopied
Three banks!
(Editor’s Note — Klarna is a bank in Europe, not in the U.S. So maybe it’s 2.5 banks?)
But what, if anything, do all of these announcements actually mean?
Let’s take them one at a time.
First up, U.S. Bank, which is exploring issuing its own stablecoin on the Stellar blockchain — an institution-friendly but lightly used payments L1 with a comparatively centralized validator structure.
To be honest, I’m not sure we should call what U.S. Bank is reportedly considering a stablecoin.
When you hear the word ‘stablecoin,’ you picture a highly liquid form of digital money that exists independently of any single bank’s balance sheet, backed by segregated reserves, and freely transferable among users on public blockchain rails.
That doesn’t seem to be what U.S. Bank is describing here. Look at the features the bank highlights as essential: the ability to stop transactions, claw back funds, and restrict usage to approved institutions or wallets.
That sounds like either (A) the world’s worst stablecoin or (B) a tokenized deposit product.
I don’t know how U.S. Bank is thinking about the relevant accounting questions — which are ultimately what determine whether something is a stablecoin or a tokenized deposit — but it seems entirely plausible that the bank wants the PR boost of using the word “stablecoin” while keeping the actual operational reality firmly on the tokenized-deposit side of the ledger.
Next, we have Cross River Bank.
This one seems pretty straightforward to me. Rather than issuing its own stablecoin or tokenized deposit product, Cross River is trying to position itself as the on-ramp, off-ramp, and compliance wrapper for everyone else’s. The pitch is simple: plug into Cross River and let them handle the nightmare of multi-chain integrations, money-transmitter rules, settlement reconciliation, and all the other crypto-adjacent chores that most fintechs don’t want to touch.
The announcement leaves plenty of open questions, such as which blockchains and tokens Cross River will support. However, it’s a logically consistent extension of what the bank already does in the BaaS space, and it doesn’t presume that stablecoins will, magically, displace every other payment rail in the next 12 months.
(Editor’s Note — I find the folks who work for BaaS banks and BaaS middleware platforms to be among the more honest industry observers when it comes to stablecoins. It’s remarkable what insights people are capable of when their personal incentives don’t get in the way!)
And that leads us to Klarna, which made a BIG DEAL out of its announcement, tweeting:
The phrasing here struck me as odd because I didn’t think that Klarna’s 114 million customers relied on the company for cross-border payments. When I asked about this, Klarna’s CEO replied:
Parsing that reply and some of the reporting and informed speculation I’ve seen from others, I think Klarna’s stablecoin ambitions (which are a 180-degree course correction from its prior position on crypto) can be broken into three stages:
- Reap the PR benefits while trying to make internal treasury management slightly more efficient. In the near term, KlarnaUSD strikes me as mostly a signaling exercise: “we’re a forward-looking, tech-driven global payments company.” You may recall them doing something similar around generative AI a while back. The operational reality, if it manifests, will likely be modest — using an internal token to streamline cross-entity liquidity movements and reduce reliance on correspondent banks. This internal treasury management use case could produce some efficiency gains, but given Klarna’s existing scale and level of operational efficiency, I would guess the gains would be incremental, not transformative.
- Increase the treasury management efficiency gains by getting external counterparties to use KlarnaUSD as well. This is where more significant savings could materialize. If merchants, payment partners, or acquiring banks agreed to settle in KlarnaUSD, Klarna could collapse multiple off-chain steps into a single on-chain transfer, potentially reducing settlement delays, FX spreads, and reconciliation complexity. However, convincing partners to adopt a Klarna-branded stablecoin — especially one on a nascent blockchain like Tempo — is a nontrivial lift.
- Develop, launch, and grow new, KlarnaUSD-powered products and services for consumers and merchants. This is the long-term prize and what Mr. Siemiatkowski was likely referencing when he said “Tomorrow many we hope!” Embedding KlarnaUSD into checkout, BNPL repayment flows, loyalty or rewards programs, cross-border commerce tools, or even consumer wallets. At this stage, the stablecoin could become less about internal operations and more about building a closed-loop payments ecosystem — one where Klarna controls the rails, the economics, and the customer relationship more tightly than it can today.
That last stage is the one that is driving much of the hype in stablecoin land these days, but it’s also (by far) the most theoretical at this point. We’ll see if Klarna (or Cross River or U.S. Bank) can make it a little less theoretical.

I’m obsessed with how OpenAI will navigate the B2C monetization opportunity/challenge that it is currently faced with, and how the choices that it makes will shape the future of agentic commerce.
Eric’s article goes into a great deal of depth on this topic (and with a refreshing level of skepticism).
