About Sieve

Inclusion only works if the money is safe.

Fraud controls built in Nairobi and Lagos, for how money moves in Africa.

The name

SmartInspection ofEveryValueExchange

A sieve is also the simplest filter. Honest customers pass straight through. Fraud is held back.

Why Sieve exists

Fraud went local. The tools didn’t.

  1. 01

    Africa built the world’s most advanced mobile money. Fraud followed: SIM swaps, mule networks and scams that move in minutes.

  2. 02

    The tools to stop it were built elsewhere, for card networks and big banks: costly and slow to deploy. Few teams can build their own.

  3. 03

    So we built Sieve: fraud controls for how money moves here. Any institution can switch it on in minutes and defend it to its regulator.

What we believe

Three rules we build by.

why?

Payout to an account added two hours ago, from a device first seen today.

01

Explain everything

When anyone asks why, the answer is a sentence, not a score.

Flag any payout to an account added less than 24 hours ago.
