When Keye is the better choice
You hold the target's raw deal files and need data cuts, cohort trends and models built from them, with every number linked to its source file. Keye was built by private equity investors for exactly that; MentionFox does not model a target's financials.
Where MentionFox fits
When you need an outside view of a company before you commit: who runs and owns it, the money it has raised, its lawsuits and legal standing, its layoffs and leadership changes. You give it a name or a website, nothing else, and every claim in the report links to its source. It is one report on one company, with no subscription. It does not read your deal documents, score decks against a thesis or build financial models; for those, use the tool above.
Questions, answered
Is Keye or MentionFox better for due diligence?
It depends on what you have. You hold the target's raw deal files and need data cuts, cohort trends and models built from them, with every number linked to its source file. If you have only a company's name or website and want what the record says about it, with every claim linked to its source, MentionFox is the faster start, and the first check is free.
