At Captide, we're constructing the autonomous intelligence layer that underpins global capital markets. Our mission is to transform how financial professionals interact with data by leveraging advanced AI to deliver precise, actionable insights from complex financial documents.

Our platform empowers analysts to query the largest database of financial disclosures with unparalleled accuracy, extracting critical information on financials, governance, and transactions in seconds. By automating the extraction and analysis of insights from a wide range of documents, including filings and investor relations documents, we enable teams to focus on strategic decision-making rather than manual data processing.
