Why I built this
In December 2022, I paid $5,000 to sponsor a single email in someone else's newsletter. It was a Christmas party, not even a AI conference, not a fancy summit. Just one creator's list, and an offer that fit.
That one placement brought in roughly $4,000 in immediate tripwire revenue. But the number that actually changed how I think about growth showed up six months later: $89,251 in downstream revenue from that single partnership. Not from an ad. From reaching the right audience, once, through someone who already had their trust.
I've since run 38 sponsorships and collabs the same way, and the pattern holds: a warm introduction from another creator consistently outperforms cold traffic. The hard part was never the strategy. It was finding the right partner, at the right size, in the right niche, without spending a week combing through Instagram DMs.
So instead of keeping that Rolodex to myself, I'm opening it up. Submit your newsletter below, browse who else is looking to collab, and reach out directly. No middleman, no fee, no application to get through.
