PSYCHOLOGICAL PROFILE
Core driver: Intellectual legacy. Stayed at Stanford 30+ years not for money or prestige — because she believes her work changes how people use power.
What turns her off: Buzzwords ("empower," "disrupt," "unlock potential"). Vague asks. Being treated as speaker-for-hire. Sycophancy.
INFERENCE LAYER
[INFERRED] Her grandparents survived the Holocaust — stated publicly in the context of her research on power and powerlessness. Do not use language like "victim mindset." It will end the meeting. Source: Stanford YouTube lecture, ~2019.
[INFERRED] 30+ years at one institution signals depth over novelty. She will be more interested in your long-term conviction than your growth metrics. Source: Stanford GSB faculty page, LinkedIn.
OPENING LINE
"I've been working through your research on power and perspective-taking with my leadership team — specifically the finding that power reduces the motivation to consider others' viewpoints — and it's mapped almost exactly onto a pattern we're seeing as our senior engineers move into management roles."
THE PROCESS
01
Add an optional identifier — company, school, city — to help the system find the right person when names are common.
02
LinkedIn, news articles, interviews, academic publications, GitHub, YouTube — queried in parallel, 30+ sources scraped in under 30 seconds.
03
Identity, background, psychological profile, inference layer, tactical advice, and a custom opening line — all calibrated to your specific context.
The differentiator is the inference layer — connecting biographical facts to psychological implications. What does 30 years at one institution signal about someone's values? What does a pivot from academia to startups at 45 suggest about risk tolerance? Any journalist can summarize facts. Dossiér tells you what the facts mean for this specific conversation.
THE FOUNDER
Leo Cao
FOUNDER
Dossiér started with a simple observation: the most important variable in any high-stakes conversation is the person sitting across from you — and most people walk in with almost nothing.
A skilled researcher can compile a dossier in 2–3 hours. A great analyst turns that into actionable psychology. Dossiér does both in under 30 seconds, using public OSINT and an AI reasoning layer built for the inference problem — not just the research problem.
Built for founders, sales professionals, and anyone who needs to understand someone quickly before a conversation that matters.
