Marketing & growth
Proven Swaps
Matches newsletter, podcast and video creators for cross-promotion swaps, and charges only when a partner actually promotes you.
In plain English
- What category is this?
- Businesses buy to get customers — SEO, ads, content, analytics, social proof. Here the focus is creator economy.
- The idea, briefly
Pair creators by measured audience overlap, verify both accounts' real numbers, hold the swap until both promotions are actually live, and rate each partner on how many of their referred subscribers are still opening after 30 days — then price per completed swap instead of per month.
More ▾- What buyers expect
People comparing tools like CrossPromoly, Creator Swaps, ShareYourFans expect the basics to work without surprise fees or missing pieces. The loud complaints are: Swap results are unmeasurable for small creators: a podcaster who ran a measured series of promo swaps and episode drops writes that after all of it there is still no practical way for an independent creator to attribute new listeners. Trigger: a solo podcaster finishes a swap and cannot tell how many listeners it produced; and authors report that swaps deliver non-converting subscribers: a Reddit author reportedly grew to almost 600 subscribers through BookFunnel newsletter swaps and then questions whether the audience only showed up for the free stuff. Trigger: reader-magnet and giveaway swaps attract freebie-seekers who never buy the creator's real product. (Snippet-only source, not opened; treated as interpreted.).

Should you build this?
Who pays: independent newsletter, podcast and video creators who need new subscribers but are tired of cold-DMing strangers for shoutouts. What the product does: it pairs two creators whose audiences actually overlap, checks both sides' real numbers, holds the swap until both promotions go live, and shows each side how many of the new subscribers are still reading a month later — charging a small fee only on swaps that happen. Beating the incumbents: CrossPromoly ($28/mo), CrossStack and A Co ($29/mo) and Creator Swaps ($9.99/mo) bill every month whether or not a swap happens, and most creators have only a few swap slots a month, so per-swap pricing can be cheaper per real result — but note Shoutcart already charges only on hire and ShareYourFans sells paid placements, so the durable difference has to be the retention score, not the billing shape.
