Susu, digitized — no smartphone required
NanaFi runs your susu group's contributions and payouts over WhatsApp, SMS, and USSD, backed by a tamper-evident ledger — so records never get lost, and every member can check their own balance and payout order without calling the captain.
Works on any phone
USSD needs no smartphone, app, or data bundle — members on basic phones get the same balance checks, contributions, and payouts as anyone on WhatsApp.
Nothing to dispute
Payout order is set by a deterministic, auditable rotation — every member can see exactly who collects this cycle and how many cycles until their own turn.
A record that can't be lost
Every contribution and payout is written to a hash-chained ledger — no more records vanishing when a collector travels, changes phones, or falls sick.
Speaks your language
English, Twi, Hausa, French, Ewe, Ga, or Dagbani — members choose their own language and every message, receipt, and reminder follows.
How it works
Chat naturally
Message NanaFi on WhatsApp, SMS, or dial the USSD code — ask for your balance, contribute, or ask who's collecting this cycle.
Confirm, then it moves
Money actions always need an explicit YES — and a wallet PIN for larger amounts — before anything moves.
Captains oversee, don't gatekeep
Captains get a live dashboard of their groups — members no longer need to call to check anything themselves.
