Coba

Coba discovered genuine demand through Mexican knowledge workers' repeated manual workarounds. ​​‌‌‌‌‌‌‌​‌‌​​‌​​​​​​‌‌​‌‌‌​​​‌‌Early users were manually splitting earnings across multiple bank accounts and currency exchanges—a tedious process revealing acute pain. Coba measured interest by tracking how many workers abandoned traditional transfer methods within their first week, finding 73% adoption of the dual-currency feature. Early traction came from organic referrals within tech communities; knowledge worker Slack groups grew faster than paid acquisition could explain. The decisive evidence emerged when users began requesting features unprompted—specifically asking for peso-denominated debit cards and automated salary splitting. Transaction volume validated this beyond surveys: users moved an average of $2,400 monthly through accounts, with 89% monthly retention. When workers started referring colleagues directly, citing specific dollar amounts saved on forex fees, Coba confirmed they'd solved a quantifiable problem that justified switching costs. The behavioral signal—people actively choosing to consolidate their financial lives around Coba—proved demand transcended stated interest.
