We have two products built for marketplaces, including Stripe Connect (https://stripe.com/connect) and Stripe Payouts (https://stripe.com/blog/send-payouts-with-stripe), which differ depending on what type of marketplace you're building. Docs for Connect are here (https://stripe.com/docs/connect) and docs for Payouts are here (https://stripe.com/docs/tutorials/sending-transfers). Feel free to email me at cristina@stripe.com if you're not sure which would be the best fit for you.
