SolydFlow
Offline-first revenue orchestration infrastructure for African mobile apps.
The What & Why
The African digital economy is fragmented across dozens of payment rails (M-Pesa, Paystack, Flutterwave) and suffers from extreme network volatility (2G/3G dominance), resulting in transaction failure rates as high as 40%. SolydFlow solves this by providing a unified Revenue SDK that handles payment routing, subscription management, and offline entitlements. Unlike standard gateways, SolydFlow functions as a resilience layer. Our SDK caches encrypted entitlements locally to allow offline access and uses a smart synchronization engine to reconcile 'Zombie Transactions'—payments that succeed at the bank level but fail to report back to the app due to network drops. We are building the 'Stripe for Africa,' but architected specifically for high-latency, intermittent-connectivity environments.
How We Use Google Cloud & AI
- Data Ingestion & Warehousing (BigQuery)
- Our mobile SDK passively collects anonymized network telemetry (latency, signal strength, carrier type). We ingest this high-volume stream into BigQuery via Cloud Pub/Sub for large-scale analysis.
- Predictive AI (Vertex AI)
- We are leveraging Vertex AI to train models that correlate network conditions with payment gateway success rates. These models will power an 'Adaptive Retry Strategy' in the SDK, predicting the optimal millisecond to initiate a charge.
- Core Infrastructure (Compute Engine & Cloud SQL)
- Our core transactional ledger is built in Go, hosted on Google Compute Engine for performance, and backed by Cloud SQL (PostgreSQL) for ACID compliance and reliability.
