OpenPay joined @airwallex , and I couldn’t be more excited. We started the company 2.5 years ago with the belief that founders building subscription businesses should only need to use one product to handle all things payments. We began under unique circumstances. Unlike many startups, we couldn’t just “move fast and break things” while developing financial technology. Case in point, we didn’t go live for 10 entire months after we began building. Our first version was a narrow subscription management and orchestration platform. It was better than competition in the few ways that we believed were critical, but it was so barebones that it was hard to sell. OpenPay’s first set of customers were dear friends and deplatformed merchants. The next beachhead was analytics. We knew there wasn’t much love for existing players. We even thought about starting here as a wedge, but the truth was clear: to deliver a truly elite experience, we had to be the ones processing every transaction AND the context they carry. Every feature we developed toward this thread had a tangible effect on our ability to close sales. Once we saw this feedback loop work the first time, we aggressively repeated it. We added customized dunning campaigns, smart retry schedules, intelligent payment routing, and soon, we had a complete subscription optimization suite. It was developed enough that, on a sales call, we could 1) listen to the customer's unique configuration of pain points, and 2) respond with a tailored pitch and demo of how we specifically addressed them. This was when we really felt market pull. Conversions jumped and we started closing more deals than we lost. Volume would increase by a meaningful multiple week over week. The feeling on the team was night and day vs what it was just a few shorts months prior. We wanted to pile in, so we started throwing around ideas around raising money for the first time. We knew we had a direct use for venture capital dollars that would be ROI . What started out as capitalization conversations with Cap49 (Airwallex’s CVC) evolved into conversations about acquisition. Our business was still early and we still had a lot of cards to turn, e.g. we had just started marketing for the first time. But meeting @awxjack made this an easy decision. It was obvious that he was a no BS execution machine who cared deeply about his people and his mission. That, coupled with the clear defensibility of Airwallex’s business and its truly global reach, locked it in for us. If not already, I think it is inevitable that @airwallex becomes a generational company. We are looking forward to playing as large of a part as we possibly can to making it happen.

What are the coolest usecases of “always on” AI?

For the past several months, @Airwallex has been the subject of false allegations originating with a board member of a direct competitor that include wild conspiracy theories about me. Today I am responding directly with facts and an independent security assessment that speaks for itself. I also want to use this moment to introduce Airwallex properly. We are a decade into building financial infrastructure that gives American businesses the ability to compete and win globally. That work continues. I was born in China. I arrived in Melbourne at fifteen with little English and no safety net. Australia gave me the education, the opportunity, and the freedom to build something. The United States represents that same promise, perhaps more powerfully than anywhere else on earth. We plan to keep building here. airwallex.com/global/blog/se…

Excited to welcome the @Leapfin team to @Airwallex. This is the first time I drove a deal on the buy-side. It’s been a privilege getting to know such a talented group of people who deeply understand the problems finance teams face every day They’ve built systems that scale and solve real-world financial problems for some of the best brands, especially around revenue recognition, reconciliation, and turning complex transaction data into audit-ready financials. Can’t wait to start working with Raymond Lau, Erik Yao and the rest of the team!
Today, we're excited to announce that Leapfin is joining @airwallex! 1/ From the beginning, our mission has been to help finance and accounting teams turn fragmented transaction data into accurate, trusted, accounting-ready financial data.

Mark is undoubtedly the person to build this business. Very fortunate to sit as a sidecar as we unlock the value of AI in healthcare

If your AI business needs FDEs to close and implement customers, should that labor count toward fully loaded CAC? I almost never see this Feels like a lot of AI companies’ metrics still assume traditional software scaling assumptions that may no longer hold A corollary to this is that more people should be talking about fully autonomous AI onboarding for products

Hearing rumors that Gemini Flash is >90% of SOTA coding performance at ~15x lower cost. Fits well with today’s dev cadence (large model plans and SLM can execute most subtasks). Dramatic cost savings if true. Might finally be time to invest in a good model router for dev workflows… that doesn’t have a supply chain vulnerability!

Thinking of all the “always on” AI usecases that will come of this. Great work @ArmenAgha
I'm excited to finally release the fruit of the research we've been doing at Perceptron for the last 16 months: Perceptron Mk1. We've been developing multi-modal recipes from the ground up to build models that perform best in the physical world, from video understanding to embodied reasoning to robotics. Mk1 is our scaled up recipe.

Cost and speed are there and the network is catching up quickly too. Worth a click if you are a founder
The next generation of U.S. B2B founders will choose A2A because startups have to go global on day one, and bank-to-bank payments are already the default in the world's fastest-growing markets. Businesses that build on A2A rails from the start won't just reduce costs, they'll have the payment infrastructure to scale across borders without rebuilding from scratch.

Most fintech companies started in the world's biggest markets and expanded outward. Most were built in Silicon Valley, with Silicon Valley assumptions. We started on the other side of the world, in a Melbourne coffee shop. Outsiders, by every measure. So we went deeper than anyone wanted to. Reimagining correspondent banking from first principles, not abstracting away the old system but replacing it. Years of obtaining licenses, building infrastructure, and shipping every financial product a growing business needs including intelligent finance. Bank accounts in 70 countries. Treasury across 25 currencies. Cards, spend management, bill pay, multi-entity, all on one platform. Built so the whole world feels like your home market. Now AI means the builders are everywhere. Global financial infrastructure has always been the hard part. Ours took eleven years to build, and it's ready for you on day one. Build the Future ↓

Somehow don’t feel an aversion to being vendor locked into Claude as I did for any foundation model last year. Claude winning my subconscious??
Introducing Claude Managed Agents: everything you need to build and deploy agents at scale. It pairs an agent harness tuned for performance with production infrastructure, so you can go from prototype to launch in days. Now in public beta on the Claude Platform.

The inference inflection point is real..running AI in prod now rivals training in both compute and economic weight. That changes how you construct your eng team, model costs, instrument observability, and close the feedback loop back into training lance.tech/p/ai-infra-roadma…

Airwallex is hard to explain because the product does a lot. But at the core it’s pretty simple: Collect → Hold → Convert → Move → Spend. This post is a good look at the core primitives
We saved our customers over $1.3 Billion in 2025 alone. That value has helped @Airwallex reach $1.2 Billion in ARR, growing 85% YoY. @Deel, @McLarenF1 , @boltapp and 200,000 other customers trust us because legacy banking wasn't meant for global businesses: • Opening a bank account in a new country takes weeks • SWIFT transfers take 3-5 days • Other platforms convert your money even when you don't want to But with Airwallex you can: 1. Open an account and get paid like a local in 70 countries Most platforms force you to convert your money into your currency and charge you a conversion fee to do it. With Airwallex, your UK client pays you in GBP and it sits in your GBP balance. Your Australian client pays in AUD and it sits in your AUD balance. When you need to pay a UK vendor or run Australian payroll, you can simply pay from the same currency in your Airwallex account which leads to zero conversion fees. 2. Send and receive money on the same day SWIFT takes 3–5 days and hits you with unpredictable fees on every transfer. But over 90% of Airwallex transactions happen on the same day. Since Airwallex uses local rails to move your money, it also happens at near-zero cost. 3. Issue multi-currency cards instantly Airwallex helps you issue multi-currency cards to your employees across the entire world. And every transaction is automatically synced to your accounting system in real-time. 4. Integrate Airwallex in your product SaaS platforms and marketplaces can also use our APIs to offer these financial services to their customers. In fact, many companies are doing it already. But this is just a glimpse of what Airwallex can do. We’re building the all-in-one financial stack your company will ever need. If you're doing $50M in revenue, you could save up to $500k in fees. And that's money back into your business. Sign up for a demo here: airwallex.com/offer/airwalle…
