How to find affiliate programs ?

my main focus is to find the affiliate in digital product/service which are recurring also. But clickbank and some other big platform are not accepting new affiliates. So how can i find it. I just need ideas that what are selling after that i will do my research manually. Is there any other way or platform where i can find affiliate program?

If you've tried affbank and offervault, then try asking at a forum like STM or Affiliatefix, and if the worst happens, then manually looking for the affprograms..
