The Opportunity

Problem

Rwandan SMEs cannot afford data-intensive martech tools like social media analytics and email automation due to exorbitant mobile data prices.

Solution

FrugalFlow builds customer lists offline, segments via simple rules, and queues SMS/emails for bulk low-data sends. Integrates Rwanda SMS gateways cheaply; emails compress & drip over days. SMEs automate nurture without data overload.

Target Audience

Rwandan small and medium-sized enterprises (SMEs) relying on mobile data for digital marketing tools

Differentiator

Hybrid SMS fallback: switches to SMS if data high, under 100KB/campaign setup.
