Building the Bridge: Powering Payments for a Global, AI Native World

Why Web2 payment expertise is the moat for the Web3 and AI agent era

An interview with Lin Wang, CEO & Founder, Payinsider

The payments industry has a habit of humbling people. For Lin Wang, CEO and founder of Payinsider, that lesson arrived the moment she launched her own company. "Once I started my own business," she reflects, "I realized I knew little about payments. The more you dig, the more you realize how much there is to learn." The admission is honest and entirely deliberate. It is the same quality of intellectual honesty that has allowed Lin to build something rare in the current AI frenzy: a company grounded in real merchants, real transaction data, and real operational complexity — while everyone else is still sketching ideas on whiteboards.

Payinsider is a payment orchestration platform built for subscription first businesses based in Shenzhen, serving the needs of a new type of growth merchant; global in its outlook, AI native, and geographically seamless. Payinsider was founded two years ago by two women, who bootstrapped the company without external capital. Lin came to payments from a non-technical background, a fact she does not hide. What she has instead is an instinct for identifying where the plumbing breaks, and the patience to fix it. That combination has made her, somewhat unexpectedly, one of the most sought-after voices at the intersection of legacy payment infrastructure (“Web2 Finance”) and the new world of AI-native commerce and Web3 finance (crypto, stablecoin etc.).

"Everyone is talking about agent payments, about Web3 — but they cannot survive without connecting to the Web2 payment world. You cannot isolate yourself from it. That's why so many people come to me: they know nothing about Web2 payment."

THE FOUNDING STORY: LEARNING BY BUILDING

Q: Payinsider is only two years old. How did the company actually get started, and how did you win your first customers without an established track record?

Lin Wang: We didn't have a playbook. Two female founders, no external funding, just the belief that there was a real gap in how subscription-based and AI-native merchants were managing their payments. Our first customer was actually a turning point for us. They were struggling with conversion rates, but they didn't have visibility into why. I looked at all their data — where their customers were coming from geographically, what payment methods they were using, where the drop-off was happening — and I put together a full plan: here is approximately how much your revenue will improve, here is how much your conversion rate will improve, and here is how we get there. That was how we landed them. Not by selling a product, but by solving a specific problem with making projections with their own data.

Lin Wang: From there, it was a referral dynamic. Once we had that first big customer, others started noticing us. We showed up on their radar — even on competitors' websites — and they reached out. That's how the Chinese based customer business grew. And now I'm trying to replicate that exact playbook in the US market and beyond.

Q: You describe yourself as non-technical. In a deeply technical industry, how have you compensated for that?

Lin Wang: By building. There is no other answer. I had no choice but to learn by doing. And honestly, that forced a kind of clarity I might not have had otherwise. I was never tempted to over-engineer things. I had to understand what merchants actually needed, and then figure out how to deliver it. The technical side followed from that. What I lacked in an engineering background, my co-founder complemented as she has 8 years engineering experience.  I continue to leverage my commercial instincts and proximity to the customer's needs.

Lin Wang: But I also want to be honest: sometimes feel like I am falling through the air as the ground seems to constantly shift. I haven't had a mentor in this industry. Someone with deep, sophisticated knowledge of how payments really works — the kind of knowledge that takes twenty-five years to accumulate — that would have changed things for me. I am still searching for that.

THE PRODUCT: ORCHESTRATION AS AN ENGINE OF GROWTH FOR the AI ECONOMY

Q: Describe the Payinsider product for a reader who understands payments broadly but may not be familiar with orchestration specifically.

Lin Wang: We sit between users, merchants and payment providers. Our core focus is subscription-first and AI-native businesses — companies whose revenue model depends on recurring billing, where a single failed transaction or a poorly routed payment can have a compounding effect on lifetime value. Orchestration, at its simplest, means we route transactions intelligently across multiple acquirers and payment rails based on geography, currency, cost, probability of approval and a number of other factors. Unlike traditional Payment orchestration platforms, when you build around recurring revenue from day one the architecture is fundamentally different. You need to manage token continuity, retries over time, billing evolution, provider switching, and revenue recovery workflows — not just route a transaction successfully once. We reduce recurring revenue loss risk  that any single point of failure — a processor going down, a currency mismatch, a compliance gap — takes revenue with it.

Lin Wang: And because we have been building with real merchants from day one, everything in our product comes from actual use cases. We are not building from imagination. Every feature traces back to a problem a real merchant brought to us. That foundation matters enormously when the industry starts moving fast, because you are not guessing what people need. 

In  the AI era, AI-native companies are global from Day 1, and they are recurring-revenue businesses from Day 1. Very early on, they already face subscription billing, usage-based pricing, hybrid pricing, localized payment methods, fragmented authorization performance, and recurring payment recovery across multiple regions. so we have built a operation system around these complex needs.

Q: What does your current transaction portfolio look like, and what does that tell you about where the product should go?

Lin Wang: About eighty percent of our customers’ transaction volume comes from the US and Europe, and the vast majority of those flows are settled in US dollars. So in practical terms, even though we are a China-based company, our product is oriented almost entirely toward Western market standards. That is intentional — we built to those standards from the beginning, not as an afterthought. The foreign exchange exposure we are solving for is a significant portion of our book, and continues to grow significantly. That shapes our roadmap: we are not a China payments company trying to go global. We are a global payments orchestration platform that happens to be founded in Shenzhen.

"We are not building from imagination. Everything has to be built to solve an actual case. That foundation matters when the industry starts moving fast."

THE CHINA SAAS ENVIRONMENT: DISTINCT CHALLENGES

Q: What are some of the unique challenges you face in the domestic China market?

Lin Wang:  One structural difference is that China historically hasn’t developed the same SaaS ecosystem as the US. The willingness to pay for software infrastructure is still relatively limited compared to mature SaaS markets, which makes vertical software businesses inherently harder to build and scale.

What we are building sits in a fairly niche category — payment orchestration combined with recurring billing infrastructure for subscription businesses. In many cases, there simply isn’t an existing mental model for it. 

The investor side has been an interesting challenge as well.  Investors in China are generally very familiar with PSPs, wallets, lending, or transaction-driven fintech models. But an independent monetization infrastructure layer serving AI and subscription businesses is a newer category, and sometimes difficult  for people to immediately contextualize in terms of market size or long-term value.

THE US MARKET: PRODUCT IS READY; THE DOOR IS NOT

Q: You mentioned the US market is the next frontier. What are the barriers?

Lin Wang: The product is not the barrier. I want to be direct about that. We built Payinsider to US standards – our platform is even hosted on a U.S. instance of AWS. Every reference point we used in development was a US company. There are no shortcuts in the product that need to be unwound for an American merchant. The gap is entirely on the customer acquisition side — and specifically, landing that first US merchant. That's the hardest part. It's the same problem we solved in China, but with an added layer.

Lin Wang: We are sometimes perceived as a Chinese company, and in the current environment that creates friction before a conversation even starts. I think about what defines a company's nationality. Is it where the founders are based? Is it where the product was built? Is it where your customers are? For us, the product is built to American (I would even “global”) standards, the majority of our transaction volume flows through US and European merchants, and we are fully capable of operating within US compliance frameworks. But perception is real, and we have to work through it.

Lin Wang: My approach is the same as it was in China: find the right first customer to partner with, prove the value with data, and let the referrals build from there. The Payinsider playbook works. I just need the first chapter.

Q: Is there a timing dimension here? Does it matter when you enter?

Lin Wang: Enormously. The window before a merchant decides to build in-house is finite. So timing is not just competitive, it's existential at the account level.  Whether they can actually execute is another matter – but it’s that perception to use a trusted partner such as Payinsider that is so critical to commercial success.  You have to be there before they think they don't need you.

However, monetization infrastructure is particularly sticky because it becomes deeply embedded into a company’s day-to-day operations — from billing and subscription management to payment recovery and revenue workflows. This is really complex work and much of it requires a payments expertise which is most likely not core to our customers’ business and strategy. Our customers who started to use Payinsider’s platform from the beginning are still with us - and continue to grow globally using our stack.

"Our biggest long-term competitor is the merchants themselves — when they get big enough to believe they can build it in-house. That's why timing matters so much."

THE BRIDGE: WEB2 INFRASTRUCTURE IN A WEB3 AND AGENT WORLD

Q: The AI and Web3 payments conversation has become very loud. Where do you position Payinsider in that landscape?

Lin Wang: I think there is a fundamental misunderstanding in a lot of that conversation. People are building agent payment systems and Web3 payment protocols as if they exist in a vacuum. They don't. They cannot. The moment any of those systems needs to touch real money — to settle, to reconcile, to handle chargebacks, to manage FX, to comply with local regulations — they run straight into Web2 payment infrastructure. You cannot route around it. You cannot isolate yourself from it.

Lin Wang: That is actually why I find myself talking to so many people in the Web3 and agent space. They come to me because they realize they don't know how Web2 payment actually works. And I understand that world. I can speak that language. I also know their language. I am genuinely curious about where agent commerce goes, and we have exciting plans on what Payinsider's role is in that future. But the foundation has to be there. Understanding the risk management, the compliance, the reconciliation — all of that requires expertise that takes years to build. You can't just layer AI on top of imagination and call it a payments company.

Q: Your interviewer, who has spent thirty years in the payments industry, made the observation that the more things change, the more they stay the same. Do you share that view?

Lin Wang: Completely. He said it perfectly: it's the same movie, with different actors and better computer graphics. The underlying principles haven't changed. There are many stakeholders with entrenched interests around every payments system — issuers, networks, acquirers, regulators, consumers. That makes the architecture inherently conservative. You can innovate around the edges, and those edges are genuinely exciting right now. But the core keeps pulling everything back to familiar territory. Even if you consider the rise of stablecoin payments; the stakeholder roles are almost equivalent; though the actors may change.

Lin Wang: And honestly, I find that reassuring. It means payments is durable. It means there will always be room for a company that deeply understands the infrastructure and can help new business models navigate it. I said this to him and I mean it: I will stick with payments no matter what else changes. It touches every aspect of daily life. That's not going away.

CLOUD VERSUS GROUND

Lin pauses when the conversation turns to how she thinks about the broader startup ecosystem around her — the fundraising machinery, the founder community, the constant churn of ideas and pivots that defines the AI moment.

Lin Wang: I have friends who are very good at being in the clouds (不切实际  Bù qiè shí jì). They know how to present a vision, how to generate excitement, how to raise a round. And there is real skill in that. But at some point, the cloud has to touch the ground. I have had people come to me — people who raised serious money on an agent payments idea or a Web3 concept — and they say, "Lin, I think I need to buy your company," or "Can we partner?" Because suddenly they need something real: real merchants, real product, real operational history. The cloud caught up with the ground.

She is not dismissive of those founders. She says she tries to learn from them, from their fundraising instincts and their ability to articulate a future. But she knows which side of that equation she is on, and she seems comfortable there.

Lin Wang: Some people survive by staying in the cloud for a long time. I survive by staying close to the ground. Both are valid strategies. But when it gets serious — when someone needs to actually build something that works — they find their way to people like me. I am okay with that.

Lin Wang's interview closes with a phrase that she delivers almost as an aside, but it may be the most precise summary of her philosophy: "I input a lot. I read a lot. I talk to a lot of different people. And then one day I will write something, because I will have a full understanding." 

In a landscape overflowing with confident proclamations, there is something quietly formidable about a founder who still considers herself a student — and is building a bridge while she studies.
