About SparkLoop

SparkLoop is a visual field guide to the growth mechanics behind viral businesses—from referral-driven products like Dropbox to cultural brands like Liquid Death.

We organize memorable companies by the loops that helped them spread, making it easier for founders, marketers, and product teams to compare patterns and shape original experiments.

Every SparkLoop product is delivered digitally for immediate access. The goal is simple: less growth folklore, more clarity about why people share.
