Hoping that now they'll have the best of both worlds!
Thus, a million little acquisitions to make the possible Stripe bundle for small companies stronger, as they become the moat. The opposite of, say, the Adyen play, when you want to lower your own costs, and make money on tiny margins to do processing for really large companies.
You don't need to rely on Stripe to do anything. There are other payment gateways, and you can file things yourself (or hire someone).
Do they make things very easy and accessible for a smaller fee than doing it yourself, yes.
What does Clerky do that Atlas doesn’t to justify the acquisition?
Clerky is an absolutely amazing product and the team there are equally as amazing.
