Grow your Substack by swapping readers with compatible newsletters
Folio Pair automatically matches your newsletter with a complementary Substack and cross-promotes each other's work — so every issue you publish becomes a reader-growth engine.
How it works
Three steps from signup to growth
Connect
Link your Substack in seconds. We pull your niche, subscriber count, and content style to build your profile.
Match
Our algorithm pairs you with a complementary newsletter — similar audience, different angle. No cold outreach needed.
Grow
Every issue you publish automatically includes a recommendation for your match — and vice versa. Compounding growth on autopilot.
