// HOW_IT_WORKS

Three steps to compounding growth

→ Deep dive: how our matching algorithm works
01

Connect your newsletter

Link your existing newsletter — Substack, Beehiiv, ConvertKit, or any platform. We read your niche and audience profile.

02

Get matched with complementary newsletters

Our algorithm surfaces newsletters with overlapping but non-competing audiences. Think: indie hackers + solopreneurs, DeFi + crypto traders.

03

Swap subscribers automatically

Both newsletters feature each other to their lists. Subscribers who click through are counted and balanced — fair, transparent, zero cost.

// TARGET_AUDIENCE

Built for builders
who write

If you have under 5K subscribers and you're in a niche community, Subloom is your unfair advantage. No PR budget required.
