Our question for them
As for every company we follow, three questions, not claims. We have not asked Deque Systems yet. When they answer, it goes here.
- Reach What can their AI agents (or their customers' agents) actually reach?
- Mandate What were they authorised to do?
- Gap Who controls the gap between the two?

Taken from the team's company map (data/companies.json on web-summit.sgit.ai), public facts only. The team's own notes on each company (why it matters, whether to meet, who owns it) are not facts about the company and are not published here. Something wrong? Tell us and we correct it on this page, dated.
The same, as data: companies/deque.json and its graph, graph/companies/deque.json (how to read them: the data, as JSON).
