Cognito Soft builds the backend, data and AI systems that products depend on: high-throughput transaction processing, event-driven services, data pipelines, and retrieval platforms that answer from your own documents.

We bring twenty years of industry experience across Java, Python, Go, Node.js and Rust, on AWS and GCP. Our engineers have delivered for product companies in the US, UK, Europe and Asia, and we run our own product, Workout360, on the same stack we recommend to clients.
