CHAPTERS
- 0:00 – 1:02
From financial chaos to hypergrowth: Airwallex’s scale in numbers
Jack opens with a candid snapshot of Airwallex’s growth and the chaotic capital needs that came with it. He frames the company’s trajectory—explosive transaction volume, sustained >100% growth for years, and rapid ARR expansion—as the backdrop for the story to come.
- •Admitting lack of budgeting/financial discipline during rapid scale
- •0 to $1B transaction volume in ~9 months as a pivotal milestone
- •Sustained >100% growth from 2015–2023 (per Jack)
- •ARR ramp: $500M (Aug) to $700M (Jan/Feb)
- 1:02 – 6:19
Surviving alone at 16: lemon factory, restaurants, and the petrol station grind
Jack recounts immigrating to Australia as a teen, losing family financial support, and having to fund tuition and living expenses himself. He describes punishing work schedules—factory labor in extreme heat, restaurant jobs, and overnight petrol station shifts—building resilience that later shaped his founder mentality.
- •Moved to Australia around age 15; lost financial support at 16
- •Worked summer lemon factory job in 40°C heat; paid ~$14 AUD/hour
- •University years: dishwasher/bartender + petrol station overnight shifts
- •Resilience formed through necessity rather than choice
- 6:19 – 11:09
Early entrepreneurial taste: the student magazine that ‘went viral’
Before Australia, Jack’s first taste of creating value came from building a student magazine designed to make advertising more compelling than flyers. The project scaled surprisingly, bringing in thousands of advertisers and teaching him how distribution and content can unlock revenue.
- •Created 'Urban Exploration' magazine at 13–14 to fund school activities
- •Turned local merchant ads into a high-demand student publication
- •Used compelling student content to drive pickup and attention
- •Claimed ~8,000 advertisers over ~18 months; profits donated back
- 11:09 – 17:36
Full-time coder, multi-million side hustles: chasing security vs meaning
After graduation, Jack worked as a developer/algo trader while building multiple businesses—import/export, phone accessories, real estate, architecture/project management. The side ventures produced significant income, but he found them unfulfilling and increasingly wanted a technology company with scale and impact.
- •Worked in finance/engineering roles while running multiple businesses
- •Import/export (olive oil, wine, textiles) described as ‘find supplier + buyer’
- •Real estate development scaled to large projects; used partners/operators
- •Financial security achieved, but dissatisfaction with ‘money-only’ ventures
- 17:36 – 23:23
The coffee shop problem that revealed SWIFT’s cracks
While building a coffee business, a blocked international payment (triggered by a name match and the SWIFT chain) pushed Jack to study the plumbing of cross-border money movement. He concludes the system is outdated, opaque, and structurally slow—sparking the ambition to build a new global network.
- •A payment got blocked and bounced back after two months via SWIFT
- •Explains intermediary chain and escalating fees/compliance friction
- •SWIFT message constraints (e.g., limited information) create false positives
- •Core thesis: money movement should behave like real-time data transfer
- 23:23 – 30:12
The $1M angel wire—before incorporation: Airwallex is born overnight
Jack shares the improbable origin story of raising the first $1M from Lucy—someone he’d just met—wired directly into his personal account before paperwork and even before registering the company. He quits his job immediately, pulls in co-founders, and begins building with extreme intensity.
- •Lucy offers to invest after a first meeting; negotiates to $1M for 20% at $5M post
- •Funds wired to Jack’s personal account with nothing signed yet
- •Jack resigns the same day; co-founders pushed to resign too
- •Early days: tiny office, sleeping bags, 20-hour build cycles
- 30:12 – 38:00
Fundraising whiplash: Australian ‘no’s’, Matrix term sheet pulled, Hong Kong lifeline
Jack describes early institutional rejection and a painful near-death moment when Matrix Partners signed then pulled a term sheet. With options narrowed, he patches together funding from other investors, learning how fragile early-stage financing can be.
- •Australian VCs often wouldn’t meet; rejections by email
- •Matrix term sheet signed then withdrawn ($2M on $8M pre / $10M post)
- •Had already turned down others; relied on Hong Kong-based Gobi + smaller checks
- •Later irony: some rejectors invest at much higher valuations later
- 38:00 – 43:39
Three failed paths to PMF: netting algorithm, SME invoicing, and the ‘vision’ Series A pitch
Airwallex’s early product attempts repeatedly miss: a peer-to-peer netting concept proves impractical at required scale, and an SME invoicing product fails due to acquisition economics. Despite knowing the current product won’t win, Jack raises a Series A by selling the infrastructure vision and a pivot toward enterprise APIs.
- •Netting/peer-to-peer algorithm couldn’t work without massive volume
- •SME invoicing/pay-by-link product struggled with high acquisition cost
- •Raised Series A largely on vision of an alternative global payments network
- •Attempted enterprise/API pivot; positioned Tencent/Mastercard as future revenue anchors
- 43:39 – 51:51
Tencent approval drama and the 404 demo: closing Series A against the odds
The Series A process becomes a high-stakes corporate maze: Tencent’s IC passes, then the founder questions why Tencent can’t build it internally. Jack waits months for a pivotal meeting, suffers a live demo failure (404), yet still wins the deal, unlocking Sequoia and Mastercard participation.
- •Tencent founder questions startup advantage vs internal build
- •Jack frames it as ‘most important meeting of my life’ after months of waiting
- •Live demo error (404) during pitch; uncertainty if firewall/PSP bug caused it
- •Tencent invests anyway; Sequoia and Mastercard join (with revenue expectations)
- 51:51 – 55:33
Shein and the lifeline customers: 0 to $1B volume in nine months
After repeated near-death cycles, the business finally catches: large enterprise customers—especially Shein—drive massive transaction volume growth. Jack recounts a critical 48-hour scramble to replace a China payout partner to avoid losing the company’s biggest customer at the time.
- •Series A extension (Square Peg) provides runway to keep iterating
- •Onboarded major tuition payments customer and Shein in early 2018
- •Volume ramps from 0 to $1B in ~9 months; fewer but much larger customers
- •48-hour emergency integration to save Shein after partner threatened cutoff
- 55:33 – 1:06:52
Stripe comes calling: the Shanghai meeting and the $1.2B offer turned down
With traction emerging, Stripe initiates acquisition talks, culminating in Patrick Collison flying to Shanghai. Jack outlines the deal structure and the internal debate, ultimately deciding to keep building—driven less by money and more by mission and long-term founder commitment.
- •Stripe outreach via CFO; Patrick spends a full day with Jack and team
- •Shared long-term vision: ‘AWS for financial services’
- •Offer structure: ~$800M on cap table + ~$350M to founders + employee pool (approx.)
- •Decision process: co-founder + leadership vote; majority wanted to keep building
- 1:06:52 – 1:11:29
Post-offer ambition—and the cost: aggressive hiring, multi-product build, and international missteps
After rejecting Stripe, Jack accelerates: hiring surges and the company expands internationally while still lacking local PMF. He admits major operational mistakes—spending heavily, building new product lines with multi-year payback, and learning commercial execution the hard way.
- •Headcount jump (~100s to ~600–700 in a year) without tight budgeting
- •Strategic shift: from money-movement to multi-product ‘global neobank’ (cards, acquiring)
- •International expansion started too early; lacked product and GTM capability
- •Took ~3 years to reach PMF in the UK; large burn and painful lessons
- 1:11:29 – 1:18:40
SoftBank reversal, COVID shock, and the Hedosophia close amid market freefall
A planned SoftBank-led round collapses after the WeWork fallout, forcing a lifeline convertible from existing investors. Then COVID hits, halving revenue exposure in tuition/travel just as a major financing closes—highlighting how external shocks repeatedly tested the company’s survival.
- •SoftBank process advanced, then partner fired and investing paused post-WeWork
- •Raised $70–$100M convertible led by DST/Tencent as emergency runway
- •During Series D close, markets tank; COVID uncertainty dominates diligence
- •Hedosophia (Ian) leads at ~$1.7B valuation with ~$150M round despite volatility
- 1:18:40 – 1:21:39
2021 capital flood, $200M burn, then profitability: sustaining extreme growth rates
Jack describes the fundraising intensity of 2021, the rationale for raising heavily to build a global banking platform, and the later transition to efficiency. Despite high burn and flat rounds, the company reaches profitability while maintaining exceptionally high growth without layoffs.
- •Multiple 2021 rounds; valuation progression (e.g., 1.7 → 2.6 → 4 → 5.5)
- •Raised ~$400M in 2021 to stay well-capitalized; later flat round in 2022
- •Peak burn near ~$200M/year; reached profitability in 2023
- •Claims never below 100% annual growth through 2023; ~90% YoY most recent quarter
- 1:21:39 – 1:35:12
Today’s financing mindset: $300M raise, founder debt for secondaries, and culture/hiring lessons
In the final stretch, Jack explains why he raised at a lower valuation multiple (gross profit focus) and why he’s personally borrowing to buy Airwallex shares. He closes with founder guidance on secondaries, CEO tradeoffs, culture mistakes, and what he’d do differently in hiring and expansion.
- •Raised ~$300M (deal began earlier); valuation framing around gross profit vs revenue
- •Taking ~$70M debt with co-founders to buy secondaries due to conviction
- •Advice: take enough secondaries to remove personal financial stress (late-stage context)
- •Key mistakes: hire recruiter earlier, don’t expand internationally pre-PMF, prioritize culture and curiosity over ‘big-company’ experience
