You can raise money for your groups or other groups on the Action Network. As described here, the first time you add a recipient to a fundraising or ticketed event page you'll be asked to create and connect a Stripe account. If you want to keep funds raised through different actions separate, you'll need to create an entirely separate Stripe account and group for each fund, or have all money go into the same Stripe account with no way of telling which recipient is which.
You can also search for other groups who have set up their Stripe accounts using the bottom section of the fundraising or ticketed event recipient addition window. If a group does not appear, they have not set up their Stripe account yet and thus are not eligible to receive funds.
Note: With Stripe, you must enter bank details upfront, otherwise you won't be able to raise money on your fundraising or ticketed event pages
