About DEFX

Most AI features fail in production — not because the idea was wrong, but because vibe-coded features weren't built for real traffic. Rate limits hit. APIs go down. Latency spikes. Edge cases the LLM never saw break the whole flow. DEFX is the missing production layer between your working demo and a product that actually ships. We work with founders, AI-first startups, and engineering teams to: → Harden LLM-powered features for production load → Build resilient infrastructure that handles real users → Surface and fix the failure modes that only appear after launch If you're building on Claude, GPT, Gemini, or any AI API — and your demo works but production is unpredictable — that's exactly where DEFX comes in. defx.in
