Stock market information service
SunSu AI is a stock market information service that answers with evidence, built on an ontology that connects scattered information — filings, trade statistics, freight rates — into relationships among companies, parts and industries. Every number carries its source and as-of date, and we don't pick stocks or recommend buying or selling.
