The screen, in this meeting room in the Bourse district of Paris, looks like the homepage of Google. A search bar, two options: "advanced search", "bulk search". Eric Bourry, "architect" of ChapsVision's solutions, types the name of a fictitious person, imagined to be involved in a shady affair. Unlike the Mountain View firm, the software called ArgonOS does not produce a list of links: it weaves connections live in all directions. Who has this person called, who are their contacts' contacts?
