How it works

Intelligent swaps.
Fair by design.

01
Connect your newsletter
Link your Substack. Flocx reads your niche, tone, and subscriber demographics to find the most complementary partners.
02
We match you automatically
Our algorithm pairs you with personal-finance writers whose audiences overlap without cannibalizing — side hustle, passive income, FIRE, frugality.
03
Swap & get paid fairly
Unequal subscriber counts? No problem. The writer sending more gets a Stripe payout, calculated at fair market rates. Zero negotiation.
