Why Roster

Stop guessing on swaps.

See whether another finance creator reaches a meaningfully different audience before you spend a slot on a promo.

Keep your edge private.

Roster is built around hashed subscriber tags and overlap bands, so you can evaluate fit without exposing your full list.

Spend time on live deals, not DMs.

When both sides are interested, Roster makes the intro so you can move straight to terms and execution.

How it works

01

Join with your publication details.

Tell Roster what you write about, who you want to reach, and the kind of promo opportunities you are open to.

02

Privately compare audience overlap.

Upload subscriber-derived tags so Roster can identify finance creators whose readers are adjacent, not duplicated.

03

Get warm intros to matched writers.

If the overlap looks useful and both sides opt in, Roster connects you to take the deal forward.

Built for list-quality-first creators

  • —Built for creators who care about list quality, reputation, and reader trust, not mass-market sponsorship spam.
  • —You do not need to share your raw subscriber list to evaluate a match.
  • —Roster only makes introductions after mutual interest, so you are not opening the door to random outreach.
  • —Early access is a waitlist, not a commitment. Join first, review the workflow, and decide if it fits your publication.
