I have been using Cashfree.com (another YC grad) for handling API based payouts and collections for our marketplace. Pretty stable. There are a lot of large businesses like Cred, Zomato, Mi etc. that use cashfree for real time API based payouts from virtual or owned bank accounts. The key to this product is success rate of payouts. Every failed payout cost about Rs.200-300 of human effort in support and reconciliation costs. PS: I am also a minor stake holder in this company.
