Case Study: Not Boring achieves 25% of new subscribers from referrals every month with GrowSurf

How A Business Strategy Newsletter Grows Subscribers By 25% Every Month Using GrowSurf

Not Boring, the weekly business-strategy newsletter run by Packy McCormick and Tommy Gamba, needed a way to turn rising organic shares into sustained subscriber growth without hiring developers. They sought a no-code referral solution to integrate directly with their Substack/Webflow setup and found GrowSurf as the ideal vendor for that challenge.

GrowSurf delivered an easy-to-implement referral platform — using automagic form detection, embeddable elements, welcome emails and a leaderboard — that required only a small JavaScript snippet and no developer work. Within two months of launch, Not Boring saw 25% of all new monthly subscribers come from referrals, with the leaderboard and a few key influencers driving large referral spikes, and physical rewards (stickers, t-shirts) helping sustain engagement.
