SOFTWARE × AI
From idea
to working product.
TechAthletes is a technology studio that develops web and mobile software, builds systems with generative AI, and helps teams adopt AI tools in their day-to-day work. We work with you from planning and development to launch and ongoing operations, starting small and validating early.
What we do
AI system development
Features and internal tools powered by LLMs: document summarization and classification, retrieval (RAG), AI agents and content-generation pipelines.
AI tool adoption consulting
Bringing Claude Code, Codex, ChatGPT and similar tools into real work: where they fit, team guidelines, cost control, and support until they stick.
Indie development & side-business advice
Validating ideas, choosing a stack, shipping and setting up payments — shaped so that one person can keep it running.
