Why Quolle exists

Every fintech in Lagos knows the moment: a user stuck at a USSD prompt, waiting for an OTP that went to spam — or never sent at all, because the email provider assumed the network never drops.

We built Quolle because the tools we imported weren't built for the conditions we ship in. Queues that hold your email through an outage and deliver the moment connectivity returns. A USSD endpoint, because *737# is a front door here, not an edge case. Naira billing through Paystack, because your infrastructure bill shouldn't fail on an FX card decline. Multi-region failover, because one region's bad day shouldn't be your users' locked-out day.

Built by Avianise. Running our own products' email first — we feel every bug before you do.
