Sami Start wants your money to move without the fuss

THE FOUNDER / A STUDY IN FRICTION

Sami Start once found himself with twenty different financial accounts. He had been interested in investing from a young age, and his enthusiasm had acquired an administrative department. Managing the accounts had become difficult. Finance had offered him choice, then sent him the housekeeping.

That small, recognisable irritation belongs near the beginning of his story. Start is the co-founder and CEO of Transak, a company that helps applications move users between traditional money and crypto. His subject is often described in the vocabulary of financial infrastructure. His original complaint could be understood by anyone who has forgotten which account holds their money.

When he encountered cryptocurrency wallets, he saw a more elegant way to organise that relationship. Yet elegance on a diagram did not guarantee an agreeable afternoon at the keyboard. Before someone could use a blockchain application, they often had to acquire the right assets and get them into the right place. The entrance examination was discouragingly elaborate.

Start has spent the years since trying to shorten it. Along the way, his ambition has become more expansive: financial applications could use blockchain underneath an ordinary interface, with payment and identity services available as components. The customer would get on with the transaction. The machinery could keep its own counsel.

Physics, code, and the cost of getting in

Originally from London, Start studied physics at Imperial College London, followed by computer science at University College London. His professional background includes technology evaluation at STFC, development at trading firm Optiver, and software engineering at Smarkets. These were jobs close to the workings of systems, where a promising idea still had to survive execution.

At Smarkets, the prediction-market business, he encountered the operational weight behind accepting customers and their money. Deposits, identity checks, and international payment arrangements consumed substantial effort. He began considering whether that work could be provided more efficiently across financial applications. The opportunity was hiding in tasks that every business needed and few customers wished to contemplate.

He was also experimenting with Ethereum. His public biography dates his smart-contract writing to 2016. Before Transak, he started a payments venture through Entrepreneur First. The combination matters: he approached crypto with experience of the difficulties involved in getting conventional money into a product, as well as an interest in what programmable assets might do.

By 2019, blockchain applications offered a particularly clear version of the problem. A prospective user might need a wallet, an exchange account, and a transfer before reaching the application they actually wanted. Developers could explain these steps in a guide. Every additional instruction was also another invitation to leave.

Two founders arrive at the same door

Yeshu Agarwal was working on a similar idea. He recalls meeting Start at a pitching event during Devcon in Osaka, where Start was presenting an on-ramp concept with particular attention to regulation and compliance. They began talking daily. Start was in the UK; Agarwal was in India. Their prospective business already had an international working arrangement.

They co-founded Transak in 2019 and joined the Consensys accelerator in New York. The product launched in 2020. In the early division of labour, Start handled sales while Agarwal concentrated on technology and product. It is a useful detail in a biography that might otherwise mistake a technical education for a permanent job description.

Agarwal remembers that winning the first customer took about a year. That customer was MetaMask. He describes ETHDenver in February 2020 as the breakthrough: conversations with its team helped the founders understand the wallet’s particular requirements. They worked towards those requirements, giving a broad idea a concrete customer and a reason to ship.

The pair’s account of the beginning has a pleasing lack of instant inevitability. There were conversations, a long first sale, and a product being adjusted to somebody else’s needs. The company existed to remove friction; its founders still had to experience a respectable quantity themselves.

A button with a considerable staff behind it

Transak’s proposition allows an app to offer money movement without independently assembling every payment connection, identity process, and crypto-liquidity arrangement. The visible result may occupy very little screen space. Providing it involves the sort of operational detail that never makes a button more photogenic.

By April 2022, Transak reported more than $420 million in total transactions. It was building teams across Miami, London, and Bengaluru, with recruitment spanning engineering, compliance, customer support, marketing, and sales. The company had more than doubled its employee base between the end of 2021 and that April. Growth required people beyond the code.

In May 2023, it raised a $20 million Series A led by CE Innovation Capital. Its offering included on-ramps, off-ramps, NFT checkout, and Transak One, a route from traditional money into smart-contract interactions. The funding was intended to support expansion and further development of onboarding tools for financial applications and games.

Start’s commercial attention often settles on modest-sounding measures: the proportion of people who complete a transaction, its cost, and the consistency of delivery. They are practical tests of whether the service deserves to be used again. A conference can applaud a vision; a customer is entitled to expect the money to arrive.

“The goal was to make something complex feel simple.”

Miami, and a preference for useful company

Start is now based in Miami. He has spoken warmly about its mix of ambitious people, venture capital, and technology talent. His description of enjoying the people there gives a little social texture to a career otherwise populated by payment operations and developer tools. Even the infrastructure business needs someone agreeable to have a conversation with.

There is another glimpse in a recommendation from former Smarkets colleague João Alves, who describes an enthusiastic engineer and entrepreneur who made work enjoyable while delivering projects. It is a colleague’s assessment, rather than a personality test, but it supplies a human counterweight to the institutional vocabulary.

At university, his listed activities included kickboxing, robotics, and an investment club. The range is entertaining: physical coordination, mechanical curiosity, and an early interest in allocating money. It would be excessive to turn a society list into destiny. It does, however, make a more interesting undergraduate portrait than the usual straight line to a startup.

His public conversations also show an interest in hiring people for their record of doing good work. Speaking in 2022 about recruiting in India, he emphasised that strong software engineers could learn blockchain principles. Experience in a fashionable category was less persuasive to him than evidence that someone could deliver.

The dollar takes the back entrance

As stablecoins gained attention, Start’s payments thesis acquired a wider audience. These tokens are designed to track a reference asset such as the US dollar. For a payments company, their relevance extends to moving value between applications and across borders. Start increasingly talks about the applications that can be built around that movement.

In August 2025, Transak announced a $16 million strategic round led by Tether and IDG Capital. At that date, it reported more than $2 billion in processed transaction volume and integration by over 450 applications. Nearly 30 percent of the volume came from stablecoin flows. These are dated company figures, useful as a snapshot of where the business had reached.

By November that year, Start was discussing more flexible components that partners could use under their own branding. A transfer could begin in conventional money, pass through a stablecoin, and finish in conventional money elsewhere. The industry calls this a stablecoin sandwich, demonstrating that finance will eventually find a lunch metaphor for almost anything.

Transak might provide one end of that process, or help at both ends. The flexibility matters to Start because established financial businesses have different needs from crypto wallets. Some need conversion; others need identity services or connections to local payments. Asking all of them to adopt the same visible checkout would limit the business he wants to build.

The passport should not have an encore

In February 2026, Start described banking, licensing, payments, and compliance as work he was particularly proud the company had undertaken. He also outlined a future in which partners could select individual services. A payroll product and an investing app might share parts of the infrastructure while retaining quite different experiences for their customers.

Identity is central to that plan. By August 2026, Transak was describing KYC Reliance and Auth Reliance modules that let eligible partner applications pass existing verification and authentication information into its services. The intention is to reduce repeated checks when someone uses Transak within an app. The permissions and controls remain part of the arrangement.

Start’s broader prediction is that wallets, banks, and exchanges will converge towards similar functions: holding value, moving it, and providing financial services. He expects more financial products to use blockchain settlement while keeping familiar interfaces. Those are forecasts, and their appeal to him is clear. The twenty-account inconvenience becomes a design problem worth attacking at a much larger scale.

Still working on the entrance

The geographical work continues alongside the product work. In April 2026, Gobi Partners announced an investment in Transak. The company said it had established its Asia-Pacific headquarters in Hong Kong and planned deeper relationships with regional banking and payment networks. International reach still depends on the particulars of local money.

In October 2026, Start appeared on On The Margin with Boaz Sobrado to discuss building Transak, financial regulation, and the unfinished work of reusable identity. The persistence of that last subject is revealing. A company can grow considerably while its founder remains occupied with the same awkward moment at the entrance.

There is something appealingly exact about the ambition. Start wants people to be able to use financial applications without first becoming specialists in their underlying systems. The work gives him plenty of technical problems, commercial negotiations, and regulatory detail. For the customer, success could feel pleasantly uneventful: open the app, move the money, carry on with the day.
