Giving affiliate marketing a (third) chance

Affiliate marketing in B2B is hard. Very much harder than in B2C.

A few years ago we tried with the big guys (CJ, ShareASale), hiring an Affiliate Manager. Without success.

Then we moved to less known platforms that don't charge anything when there is no sale (Australian ClixGalore and Polish Afiliant). We didn't promote the program at all, there was some sales, but very little. No success either.

Now we decided to try again and we integrated with German Reditus. It's a modern affiliate platform (not a network), also without any fixed costs.

We're goingto reach out to our affiliates from the past (if they still exist) and to our customers.

Any ideas how to recruit B2B affiliates?
The "affiliate directories" mentioned in the other thread don't look very promising.
