Grow Your Substack by Swapping Readers with Writers Like You
We match productivity and solopreneur newsletter writers for one-time curated digest swaps. Your best posts reach their subscribers. Their best posts reach yours.
Free to join. No credit card required. First swap is on us.
How it works
Three steps to your next hundred subscribers
Join & share your Substack
Tell us about your newsletter — topic, subscriber count, and what kind of writers you want to connect with.
Get matched with a complementary writer
We pair you with someone whose audience overlaps with yours but doesn't duplicate it. Think: synergy, not competition.
Swap curated digests
We send a hand-picked digest of your best posts to their subscribers — and theirs to yours. New readers, zero spam.
Why it works
Your readers already want this
Someone who subscribes to one productivity newsletter is highly likely to subscribe to another. That's not a guess — that's how audience overlap works.
Cold ads convert at 0.5-2%. Cross-promotion through StackSwap? 5-15x better. Because you're not interrupting strangers — you're being introduced by a writer they already trust.
