Episode Details

On this episode of The Innovators, I spoke with Jasper Fu, CEO of CoinSub, about what crypto payments actually look like when you strip away the hype and aim for real adoption.

CoinSub has been operating for roughly two and a half years and has grown to a 22-person team, most of them engineers. The company’s focus is narrow by design. Instead of trying to convince millions of merchants to adopt crypto directly, CoinSub sells infrastructure to payment service providers. These are the companies that already process card payments for thousands, sometimes hundreds of thousands, of merchants. CoinSub’s bet is that adoption happens faster when crypto looks like just another payment option, not a new system merchants have to learn.

Fu framed the problem simply. Crypto and stablecoins are often described as liquid assets, but in practice they are hard to use for everyday payments. Merchants do not want to think about wallets, chains, or conversions. They want money in their bank accounts. CoinSub handles the movement behind the scenes, converting between dollars, Bitcoin, and stablecoins, then packaging that capability so payment processors can offer it under their own brands.

For merchants, the experience is meant to feel familiar. Crypto becomes another icon at checkout, alongside cards or digital wallets. Whether funds settle as stablecoins or dollars is not something the merchant has to manage. Fu compared it to card networks. Merchants do not think about how Visa or Mastercard clears transactions, they just expect it to work.

That distribution strategy also shapes CoinSub’s view of competition. While many crypto payment companies target merchants directly, CoinSub targets the providers upstream. There are billions of dollars flowing through a relatively small number of payment processors, many of which lack the technical capacity to build crypto infrastructure themselves. CoinSub positions itself as a way for those companies to keep pace without rebuilding their stacks.

Usage data suggests there is real demand, even if it remains early. Fu said CoinSub processed roughly $400 million in transaction volume last year. That number varies widely by region and industry, but it reflects actual consumer-to-business payments, not trading or speculation. Some sectors adopt faster than others, including cross-border commerce and industries that struggle to maintain stable card processing relationships.

Fu pushed back on the idea that crypto adoption hinges on hype cycles. He views blockchain and tokenization as infrastructure, a more efficient way to store and move data and value. Speculation and scams, he argued, appear in every new technology wave and do not define the underlying system. In his view, hype draws attention, but utility determines what survives.

Stablecoins are central to CoinSub’s timing. Fu said regulatory clarity, treasury backing, and growing institutional interest have aligned incentives across governments, issuers, and payment networks. Payments and commerce, he said, are the logical next phase after issuance. Once stablecoins exist at scale, the question becomes how people actually use them.

Fu’s path to CoinSub started outside crypto. After leaving a corporate role, he took time off to think about what he wanted to build next. Payments stood out as a place where incremental efficiency could have broad impact. Making money movement cheaper and more accessible, particularly across borders, felt like a net positive use of time and capital.

That mindset also shapes CoinSub’s internal culture. Fu said he prefers the startup environment because it allows for empathy-first leadership and long-term thinking. He believes effort cannot be bought, only invited, and that teams perform better when people are treated
