Welcome to Sente: A Fintech Platform Built for Africa

Sente is a highly-available, ultra-low-latency, multi-country fintech platform for Africa. We move money across heterogeneous rails — USSD, mobile apps, merchant checkouts, VISA/global card schemes, and local schemes like M-PESA — and post every movement to one canonical, provably-correct double-entry ledger.

Our stack

**Core ledger** in C# / .NET 10 — because correctness at scale demands a statically-typed, high-performance runtime.

**Async ingestion & USSD** in Python / FastAPI — because rapid iteration on partner integrations matters.

**Client tier** in TypeScript — Next.js for web, Expo for mobile.

Our principles

Immutable ledger: every balance is derived, never mutated.

Serializable isolation on every money write.

No floats anywhere near money — `int64` minor units only.

PII tokenized in-region before it crosses any border.

We're just getting started. Follow this blog for updates on what we're building.
