A dollar account is an unremarkable object in New York. It sits behind the rent, the card, the payroll deposit and the little coffee that somehow costs seven dollars. Move the same account across an ocean and it can become contraband by bureaucracy: difficult to open, costly to fund, awkward to spend and nearly comic in the number of intermediaries required. Shahryar Hasnani has built his young company around that change in meaning.
Hasnani is the co-founder and CEO of Karsa, a financial-services startup from Y Combinator's Winter 2025 batch. Its proposition sounds almost defiantly plain: give people and businesses in emerging markets an account that can receive, hold and move dollars. Under the hood sit bank transfers, stablecoins, local payout networks and cards. On the screen, the hope is that none of this feels exotic. Money should arrive. Value should remain. The customer should get on with Tuesday.
The founder behind that plain interface has spent much of his life crossing borders and vocabularies. Born in Philadelphia, he grew up in Dallas, Houston, Karachi and Dubai. At Northwestern University he majored in economics and minored in creative writing. He wrote South Asian and diasporic fiction, and his poems and stories appeared in the university's Helicon Magazine. An economist who writes fiction is trained to notice two different things at once: the machinery of a system and the person caught inside it.

The rails before the account
After Northwestern, Hasnani joined L.E.K. Consulting. Earlier internships at Newmarket Capital and Capital One had already put investing, product management and analytics on his résumé. Consulting added another useful founder's habit: taking a complicated market, disassembling it and returning with a recommendation before the conference room coffee cooled.
Then came Scroll, the Ethereum scaling company. Hasnani started in partnerships and became Partnerships Lead. The public record from those years shows him discussing zero-knowledge virtual machines, developer ecosystems and the design choices involved in scaling blockchains. In 2024, he joined a recorded discussion on Layer 2 networks. He also appeared as Scroll's point of contact in ecosystem proposals, translating an intensely technical system for developers, partners and governance communities.
That sentence has aged into a decent description of Karsa's operating theory. Technology can create a route. Trust persuades anyone to use it. At Scroll, the audience was developers deciding whether to build. At Karsa, it is a freelancer in Lahore, an online seller in Karachi or a business owner trying to pay a supplier abroad. The vocabulary changes. The work of building confidence does not.
What the customer sees vs. what the product must coordinate
Two friends and a kitchen
Karsa began with Hasnani and Dale Wilson, a protocol engineer who became the company's co-founder and CTO. They had been close friends for years and entered crypto around the same time. Their version of the origin myth contains refreshingly little myth: Hasnani says he got Wilson to “FOMO in,” and the pair initially worked from Wilson's kitchen in New York.
The kitchen detail matters because Karsa's first pitch was enormous. More than a billion people, the founders argued at launch, live with serious inflation and limited access to assets such as dollars. Existing stablecoin products often looked like trading terminals, complete with wallet keys, chat threads and a peer-to-peer ritual that could make buying digital dollars feel like arranging a minor heist.
Karsa placed itself in the middle. It matched orders, managed verification and appeals with suppliers, and hid wallet mechanics from customers. The user met familiar verbs: deposit, receive, save, withdraw, spend. The company met the awkward nouns.
The founders' personal connection to the problem gave the broad pitch a sharper edge. Hasnani's family in Pakistan still dealt with inflation and restrictions on dollar access. He and Wilson had also worked across the Middle East and Southeast Asia, watching stablecoins become savings instruments rather than speculative chips. Their initial operating list included Pakistan, India, Nigeria, Kenya and Paraguay. These were not decorative pins on a global map. They were markets where the workaround had already arrived before the polished product.
Make the machinery boring
Karsa's product evolved quickly. The company launched a mobile app with a global dollar wallet, a virtual US bank account and transfers to and from the United States. It later rolled out cards and direct withdrawals from USDT and USDC into Pakistani bank accounts as rupees. In early 2026, Hasnani announced USD accounts built specifically for Pakistan, combining banking rails with stablecoin routes and local withdrawals.
His public explanation of the approach is blunt. Peer-to-peer trading grew because people lacked a better choice. It carried obvious risks: strangers' bank accounts, informal dealers, frozen funds, long waits. Karsa's answer was not a moral lecture about grey markets. It was a regulated route that could make those workarounds less necessary. “We don't need to fight P2P,” Hasnani wrote. “We're already making it irrelevant.”
There is swagger in the line, but also a practical product insight. Workarounds rarely disappear because someone scolds the user. They disappear when a legal option becomes faster, safer and pleasantly dull. Karsa's design challenge is to preserve the border-crossing advantages of stablecoins while offering the legibility people associate with an account, a card and a bank transfer.
The job includes occasional public embarrassment. After an influx of customers overwhelmed the app, Hasnani posted that it had “kind of broke.” The sentence is useful evidence of temperament. He acknowledged the failure, said it was fixed and paired the update with an offer for users who had been caught in the rush. Startups adore stories about heroic scale. Actual scale tends to arrive as a broken signup flow and a support queue.
A writer's instinct for the last mile
Hasnani's creative-writing past could be treated as charming biographical garnish. It is more interesting as an operating advantage. Infrastructure companies are forever tempted to make the technology the protagonist. A fiction writer knows that the interesting character is usually the person trying to get through the door.
Karsa's public language has gradually shifted closer to that person. The early description emphasized a stablecoin neobank. Its current website speaks to e-commerce sellers, globally incorporated businesses and people receiving client or platform payments. It advertises support for several currencies and stablecoins, payouts to dozens of countries and cards for ordinary business expenses. The underlying systems remain intricate. The nouns at the surface are invoices, suppliers, contractors and ads.
His own public language follows the same migration. In the Scroll years, Hasnani spoke in the careful clauses of infrastructure: developer activity, proof systems, consensus trade-offs. He was comfortable saying that an answer did not yet exist. At Karsa, the sentences became shorter and the stakes more immediate. Hours instead of days. A bank account instead of a dealer on WhatsApp. A card that works. The simplification is rhetorical, but it also functions as a product checklist. Each crisp claim creates an operating obligation for the team behind it.
It also makes his combination of subjects at Northwestern look less accidental. Economics gave him a way to discuss inflation, incentives and the price of moving money. Creative writing trained attention on motive, voice and the detail that makes a general problem feel lived. His undergraduate biography said he focused on South Asian and diasporic fiction. Karsa addresses a commercial version of the diasporic condition: work, family and money distributed across jurisdictions that do not cooperate merely because a person needs them to. A payment can be technically global and still fail at the final bank, the final exchange rate or the final identity check. The last mile is where the plot usually turns.
This shift also reveals the pressure on a founder whose company lives between crypto and banking. Crypto prizes openness and self-direction. Banking prizes compliance, recourse and predictability. Emerging-market customers need useful parts of both. The product has to travel globally while respecting the peculiar friction of every local exit. Universal rails, local trust.
Hasnani's career now reads as a sequence of translations. Economics to fiction. Consulting to crypto. Protocols to payments. New York infrastructure to a Pakistani bank account. He has spent the public part of his twenties moving closer to the end user while keeping the systems view that got him there.
Karsa is still a small company, and its ambition carries the usual burden of financial startups: every promise must survive regulation, liquidity, fraud, support and the physics of moving money. The interesting achievement so far is not that those problems have vanished. It is that Hasnani and Wilson have made them look, from the front, like an account.
That may be the cleanest version of the founder's aspiration. Export the ordinary. Give a dollar account permission to stop being a privilege or a puzzle. Let the customer complain about the price of coffee instead.
