yep quadpay is already bigger than Sezzles entire business by about 50 percent if I recall the latest numbers. And they are in the US a market 8 times the size of Canada's in terms of potential customers and quadpay isn't a slouch growing at the rates they are. I can't see Sezzle catching the quadpay numbers.
I believe when quadpay was acquired they had targets to reach 9 billion USD TTV by 2023. 673 million q1 for quad, so will expect about 3 million TTV from quad in 2021. If it doubles year on year it will be 12 billion AUD by fy2023. Roughly 9 billion USD so they are on track for that or slightly ahead. 7 percent of 12 billion AUD is 840 million revenue just off Quadpay in FY2023. Then add UK, ANZ, Canada and Europe figures to that.
I expect FY2023 annual report the business should do about 22-24billion TTV. The ANZ region are still doing 60 percent YoY growth vs Afterpays 15% YoY growth in the ANZ, so expect ANZ to contribute a likely 8 billion TTV just off the ANZ region by fy2023. that's asking for 2 billion TTV from UK and rest of world. This sounds about right.
Revenue of say 6.5 percent off 20 billion..... That's 1.3 billion revenue, nearly three times the revenue Afterpay did fy2020 with a market cap of 25 billion!

Hold your shares people. Zips got a long way to run
