The short answer
Company due diligence is the structured investigation of a company before a decision — an investment, an acquisition, a contract or a partnership — to confirm what it says about itself and to surface risks: who owns and runs it, whether it is sanctioned or in litigation, how it is financed, and how it is performing.

Company due diligence in practice
Due diligence ranges from a quick screen to months of work with lawyers and accountants. Whatever the depth, it answers the same core questions: is this entity who it claims to be, who is behind it, what could go wrong, and what supports the upside.
Much of the groundwork comes from public records — company registers, regulatory filings, court dockets, sanctions lists and news — before any private data room is opened.
Why company due diligence matters
- Identity: the right legal entity, its identifiers and its status.
- People: officers, directors and beneficial owners, and their other affiliations.
- Risk: sanctions, politically exposed persons, litigation, enforcement, insolvency and adverse media.
- Substance: filed financials, funding history, hiring and traction.
Company due diligence in MarketPrior
MarketPrior automates the public-record layer. You name a company or founder; it resolves the entity, sweeps its sources in parallel — in internal benchmark runs the median was about 25 seconds per company — and returns a fused risk × upside verdict with every finding cited to its record.
It is decision support for the first pass and for ongoing monitoring. It does not replace private-data review, references or management meetings, and it is not investment advice.
