Startup intelligence platform built on public evidence
A startup intelligence platform should help an operator move from a broad market question to inspectable companies, products, demand signals, and evidence. High Signal combines a daily brief with a public company universe and evidence-backed signal archive. It is designed for discovery and follow-up research, not as a private-company database with unverifiable completeness claims.

What High Signal covers
High Signal's company universe is built from official YC, Antler, a16z, and Techstars directories. The underlying corpus contains 12,964 unique companies. The public discovery policy does not index every generated profile: it currently marks 5,178 company pages eligible only when the description, product facets, and similarity evidence clear the published threshold. Pages below that threshold remain available where appropriate but are withheld from search discovery until their evidence improves.
Find companies by what they do
Company profiles retain source affiliation, description, cohort or program evidence when available, and extracted product, use-case, customer, industry, and technology facets. Search uses those fields instead of relying only on a company name. Similar-company links are deterministic and reciprocal, with match reasons exposed so the connection can be inspected rather than accepted as a black-box recommendation.
Connect the directory to live signals
A directory is most useful when it connects static company context to changing evidence. High Signal links its company universe to published signals, entities, sectors, opportunities, and recurring signal types. The Daily Brief compresses the strongest current observations; the deeper pages let a reader inspect the companies and evidence behind them.
What the platform does not claim
High Signal does not claim that every startup has complete funding, revenue, employee, or customer data. It does not turn a short accelerator description into an authoritative company profile. The corpus policy deliberately withholds thin pages from indexing. Source links and update timestamps remain visible so a reader can verify freshness and scope.
A practical research path
Begin with the company universe when you know a company, category, accelerator, location, or product facet. Move to similar companies to map a local competitive set. Then inspect signals and the Daily Brief to see whether current evidence changes the picture. Use the methodology and data pages to understand what High Signal ingests and what qualifies for public discovery.
