So from a gut feeling that sounds right, finance is a pretty complicated domain with a lot of per vendor interactions, and Shopify outsources their payment stuff to Stripe.

Also on a headcount level, Google tells me Shopify has 3,500 employees to Stripe's 9,500. Obviously neither company is compromised entirely of engineers, so this is a ballpark estimate.

GitHub feels like the real case where there might be a larger codebase. It's in the middle for employees (6,500), but it's existed longer than Stripe (though not as much longer as my gut feeling told me, interestingly)
