Voyant.io is a brand-context platform that turns a company's positioning, messaging, personas, products, pricing, and competitive intelligence into structured "context streams" that any AI tool or agent can read at generation time, so AI-produced copy stays on-message instead of drifting or hallucinating claims. The product is delivered as a large FastAPI-based REST API (783 operations across 79 tags covering context streams, RAG search, messaging frameworks, target graph, telemetry, social signal harvesting, competitive intelligence, and content generation), a hosted MCP server exposing 15 tools to agent clients, and a set of published agent-governance files (`/.well-known/llms.txt`, `/.well-known/context.txt`) that declare training permissions and inference-control rules for the domain itself. Marketed to B2B GTM teams scaling from $5M to $100M ARR. Pre-seed, founded by Andrew M. Brown; the API runs under the internal name "VoiceForge".
