# Data Subsystems, Inc.

> Data Subsystems (datasub.com) is an applied-AI product studio. We build production AI systems — RAG, AI agents, and AI-content/AEO — and the modern web, commerce, and payments around them. Founded in 2008 by Alex Shortov; a US company headquartered in Clearwater, FL, with US-based management.

Data Subsystems designs, builds, and operates production software for ambitious product teams. We are not a generic web agency: we ship evidence-grounded AI systems to production, build our own products (including the AEO platform aeocontent.ai and its AEO Rank scoring engine), and carry fintech-grade security and reliability into everything we build.

Core areas: applied AI (retrieval-augmented generation, AI agents, conversational support automation), Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO), fintech and payments engineering (ACH, eCheck, payment APIs), modern web and e-commerce, industrial and engineering document intelligence, and multi-cloud data platforms.
