From the Ground Up: Jasper Fu and the Invisible Money Layer That Makes Stablecoins Feel Normal

Jasper Fu, co-founder and CEO of Coinsub, doesn’t talk about crypto like a crusader. He approaches it like an engineer who wants the plumbing to work so well that nobody notices it. After a winding career that moved from actuarial and data science roles to tech consulting, engineering, and product management, Fu arrived at a simple conviction: technology is a kind of practical magic—an ability to turn an idea into something real, scalable, and useful. That belief, paired with a strong sense of human-centered leadership, now shapes Coinsub’s mission to bring stablecoin payments into everyday commerce without forcing merchants or payment platforms to become blockchain experts.

Fu’s background includes time at Aon Hewitt and PwC, followed by an unconventional pause that says a lot about how he thinks. He stepped away from corporate life to pursue photography and become a yoga instructor, spending months in India completing advanced yoga teacher training. That period wasn’t a detour so much as a recalibration: a chance to reset priorities, build empathy, and decide how to create impact at scale. When he returned to tech, he chose the startup path as the most direct way to combine enterprise experience, practical problem-solving, and a deeper awareness of how people actually adopt new ideas

 

Fu has been involved in blockchain and crypto for roughly a decade, but Coinsub emerged from a particular insight: the promise of crypto-enabled payments has consistently outpaced real-world adoption. While working on a global eSports tournament platform, he saw how crypto could enable people anywhere to send money in and receive conditional payouts based on predetermined outcomes. What stood out wasn’t the novelty; it was the structure. The system made it possible for money to move internationally with rules attached—reliably, programmatically, and without requiring the participants to understand the underlying rails. That gap between what crypto can do and what the market is ready to use became the starting point for Coinsub: meet businesses where they are, reduce disruption to near-zero, and translate crypto’s benefits into outcomes that normal operators care about.

Coinsub’s current wedge is payments infrastructure—specifically for payment service providers rather than individual merchants. Fu’s logic is straightforward: if stablecoins are going to become a mainstream payment method, merchants won’t be the ones rebuilding their stack to support it. They’ll get it through the providers already embedded in their checkout flows: the platforms that handle card processing, settlements, and merchant relationships. Coinsub builds the behind-the-scenes capabilities that allow a customer to pay with crypto while the merchant ultimately receives value in familiar terms, typically landing in the merchant’s bank account as they do today. The goal is access without added complexity: one more payment method, net new revenue potential, and minimal operational lift.

A critical part of Fu’s approach is acknowledging how early the market still is. In his view, many crypto insiders dramatically overestimate public awareness and interest. The average business operator often can’t distinguish stablecoins from bitcoin, or NFTs from blockchain, and many simply don’t care. That reality changes the job. Coinsub doesn’t win by persuading everyone to love crypto; it wins by presenting stablecoins as infrastructure—more like a better ledger system than a philosophical shift. Over time, Fu expects stablecoins in commerce to become so normalized that the label fades, similar to how “cloud” moved from buzzword to default.

Coinsub also zeroes in on subscription payments because recurring revenue is both enormous and operationally difficult. Traditional payment systems still struggle with retries, failures, and edge cases at scale, and crypto rails historically weren’t built for ongoing authorization. Coinsub’s solution treats subscriptions as a programmable payment agreement enforced by technology, with guardrails that prevent overcharging by design. It’s a practical expression of what stablecoins can enable: trust reduced not through promises, but through architecture.

Fu’s leadership style mirrors the product philosophy: minimize friction, amplify results. He’s candid about the unglamorous work of being a CEO—deck-building, constant iteration, and doing what’s uncomfortable, including visibility and sales-facing responsibilities that don’t come naturally to an introvert. Rather than fighting that temperament, he reframes it as an advantage: heightened awareness, deeper consideration, and empathy that improves communication. In his view, the job is to turn every trait into an asset in service of the mission.

In the near term, Coinsub is focused on scaling—expanding growth and outreach after proving its technology with meaningful processing volume. But Fu defines success with two metrics: capturing a significant share of the stablecoin payments opportunity through payment providers, and preserving a culture rooted in empathy as the team grows. He sees money as a powerful tool, but not an ultimate purpose. The day-to-day experience—who you build with, how you treat people, and the energy you create—matters more than the abstraction of moving numbers around. For Fu, the real product isn’t just payments infrastructure; it’s a future where financial rails become quietly more efficient, and the humans building them don’t lose themselves in the process.
