Freedx Tech Stack

Cryptocurrency exchange platform with ML-driven trading and cross-chain liquidity

Financial Services San Salvador 51–200 employees Founded 2024 Privately Held

Freedx is a newly launched crypto exchange built on .NET and C# backend services, with a tech stack heavy on ML infrastructure (PyTorch, TensorFlow, scikit-learn) and real-time data systems (Kafka, NATS, TimescaleDB). The pain-point pattern — low-latency response times, liquidity-driven architecture, high-frequency trading — reveals a platform optimized for active traders rather than retail onboarding. Growth is the bottleneck: hiring has decelerated, but leadership focus remains on go-to-market, CAC-to-LTV efficiency, and affiliate scaling.
