You can do "payouts" with Stripe Connect. Stripe doesn't have a money transmission license so they can only do a payout when it's tied directly to a charge (like marketplace). You could also take a look at Payoneer.
Yep, went that route (Stripe Marketplace) and then realized later that it had to be tied to some charge. We wanted to payout users at end of the month so it wouldn't work for our case. Now, Payoneer is interesting. I really like Plaid interface to tie into the banks, do you know if it can integrate with it or even possibly have it's own Plaid like widget?
