## Company Overview

BusinessAgent (business-agent.cc) is a multi-channel AI API infrastructure provider for development teams. We operate 4 independent channels to official AI models (Claude Opus 4.6, Codex 5.3/5.4, Sonnet 4.6). Any single channel failure triggers automatic failover in under 1 second — your team experiences zero downtime.

We serve teams from 3 to 500+ developers. Our API is fully OpenAI-compatible — teams can switch by changing one endpoint URL with zero code changes.
