The architecture of trust.
Traditional referral marketing is often treated as an afterthought—a messy combination of manual payouts, broken links, and fragmented data. We saw founders and growth leads struggling to reconcile the value of word-of-mouth with the complexity of technical implementation.
Our approach is different. We focus on technical precision and aesthetic restraint. By embedding sharing loops directly into the product experience, we make the act of recommending a product as natural as using it.
Today, Cello powers growth for companies like Typeform and Hera, turning referral programs from a cost center into the lowest CAC channel in their marketing mix.
