It seems Stripe is ideal for a partnering approach - have national established payment processors hook up to Stripes backend (after a vetting/selection process, of course). That way they can expand quickly without having to internalize the many different quirks of payment systems across the world.
If there is a stripe beta in the uk sometime soon, we'd love to take part...
Is there anywhere we can join a waiting list for a uk beta? Perhaps it would be worth keeping a list per country of companies who are interested to judge demand?
We're crying out for you !
