§ 01 — What the agent actually does

Not a chatbot.
An analyst with a method.

The moat isn’t the data sources — those are public records anyone can pay for. It’s the discipline the agent applies to them. Four habits that separate Sentinel from a search wrapper.

Multi-lens analysis
Every Standard and Institutional report passes through three perspective lenses: devil's advocate, regulator, counterparty. The agent surfaces what each kind of reader would actually flag — instead of writing one bland report.
Behavioral consistency
Claimed bio versus verified records. Narrative drift across years. Suddenly-deleted public posts. The agent compares what subjects say about themselves with what the public record actually shows — the way a careful human analyst would.
Every claim labeled
VERIFIED, REPORTED, INFERRED, or UNCONFIRMED. Sources cited inline. Contradictions surfaced explicitly. A Sentinel report tells you not just what's true but how confident to be — the discipline most AI tools skip.
Never fabricates
No hallucinated case numbers. No invented citations. When the agent can't confirm something, it says so and lists it as an open lead. Hard rule, enforced in the system prompt and the audit trail.
§ 02 — Output tiers

Depth scales to stakes.
Not the other way around.

A bouncer doesn’t need a 60-page institutional report. A $50M acquisition isn’t safe with a one-pager. Sentinel listens for the decision behind the request and calibrates accordingly.

§ 03 — Source network

Public records first.
Bring premium when it matters.

Most expensive DD platforms are aggregators around the same public records the agent reads directly. Where institutional depth is genuinely needed, connect your own subscriptions — Sentinel orchestrates without ever touching your seats.

The same primary records Kroll, K2, and PitchBook themselves rely on. Sentinel reads them directly, so you don't pay an aggregator markup.

Executive Summary

VERDICT — Proceed with Conditions. Subject entity is operational, properly formed, and revenue-generating. Two material red flags warrant indemnification carve-outs in the SPA before close.

Top Red Flags

[VERIFIED] Pending Delaware Chancery suit (C.A. No. 2025-████) — fiduciary duty claim filed Jan 2026 by minority LP. Material to deal value.[REPORTED] Founding partner referenced in 2023 FT investigation re: undisclosed related-party transaction at prior firm. Not independently confirmed.[REPORTED] Two senior departures in last 6 months — pattern, not single event.

Positive Signals

[VERIFIED] Clean across OFAC, UK HMT, EU consolidated, UN sanctions.[VERIFIED] No PEP exposure on principals (3 individuals screened).[VERIFIED] Audited financials available — Big-4 reviewer, clean opinion FY24.

Confidence

Overall: High (84%) — primary records accessible, ownership chain mapped to UBO. Limiting factor: one offshore vehicle (Cayman) with restricted disclosure.

Recommended Next Steps

1. Counsel review of C.A. No. 2025-████ filings before LOI2. Direct reference call w/ 2 of 3 departing seniors3. Cayman UBO walk-through via local counsel_
§ 06 — Common questions

The objections we
hear most.

How is this different from asking ChatGPT?+

ChatGPT will hallucinate sources and tell you what you want to hear. Sentinel labels every claim VERIFIED, REPORTED, INFERRED, or UNCONFIRMED, cites the actual record, and runs disambiguation on common-name false positives. The discipline is the product.

Is Sentinel FCRA-compliant?+

Sentinel is not a Consumer Reporting Agency and reports are not for hiring, firing, credit, insurance, or housing decisions unless you are operating as a registered CRA in your jurisdiction. The agent is built to refuse those use cases at intake. Use Sentinel for commercial DD, vendor vetting, donor screening, KYC enhancement, and investigative research.

What about GDPR for European subjects?+

Sentinel processes only public-record data with a legitimate-interest lawful basis under Article 6(1)(f). Subject access and erasure requests are honored within 30 days. Data is retained for the regulatory window and then archived.

Where do my queries and reports live?+

On your account, not in a shared training corpus. Reports are encrypted at rest in our database. Anthropic, our LLM provider, does not train on API traffic by default. We can offer enterprise customers further isolation under contract.

Can I use my own PitchBook / FactSet / Moody's seat?+

Yes — on Institutional and Enterprise tiers. Connect your existing subscription via OAuth and Sentinel orchestrates the agent against your data without ever touching your seat or storing your data.

How accurate is it really?+

On the validation set we run internally, sanctions screening matches the primary registries 100% with zero false positives after disambiguation. Litigation coverage is strongest in US federal and UK; weaker in jurisdictions with restricted court access. The agent always flags coverage gaps explicitly — that's part of the report.
