Look, if you want B2B affiliates, stop chasing influencers with big follower counts. They're useless. The real money is in niche communities where marketers actually transact - growth hacking forums, indie hacker circles, private Slack groups. That's where people are already discussing affiliate setups, not just posting for likes.
I've had way more success going direct: find someone already promoting a complementary product in your space (non-competing, obviously). Reach out with a concrete offer, not some generic "let's partner" nonsense. B2B affiliates care about commission structure and support, not vanity metrics. A solid margin plus real backend help will get you further than begging them to tweet.
Also, don't sleep on affiliate agencies. They manage multiple campaigns and are far easier to onboard than individual creators who flake after one bad month.
Cold email works better than any DM. Find their email, reference their existing audience, and spell out exactly why your product fits. Keep it short, keep it specific. That's how you get actual ROI, not just warm fuzzies.
