Canonical Company Search

Canonical is a company data API and remote MCP server built for the long tail — the companies others miss. Describe what you want in plain English (or pass structured filters) and it retrieves from a curated corpus of millions, verifying each candidate against products/services, target customer, and business model with an LLM evaluator. You get a precise, domain-keyed shortlist: signal, not a noisy page of links.

Two workflows, one graph. Discovery: search for companies matching an ICP, or pull look-alikes from a seed domain. Enrichment: resolve a free-text company name to a canonical domain, then retrieve the full company record — funding (round series from pre-seed through growth, amount raised, post-money valuation, investors, last-raise date), founding year, employee count, HQ city/state/country, founder and executive slates with role, LinkedIn, and prior-employer tags like FAANG or unicorn, plus corporate-family links (parents, ultimate parent, subsidiaries, joint ventures). Founder and leadership coverage is a curated subset, not the whole corpus.

Built for agents: everything is keyed by domain, so an agent runs the whole loop without holding state — look up a name, drill into the profile, hop to a related company, or fan out to look-alikes.
