§ 01 — Why this exists for solos

Most solo operators get burned at least once.

It happens the same way every time. A new client appears, the work looks reasonable, the money sounds real, and you're busy. You skip the diligence step because there isn't a process — just a Google search and a gut check.

Then the invoice goes unpaid. Or the company turns out to be dissolved. Or the principal has a string of pending federal litigation you'd have spotted in two minutes if you knew where to look.

Sentinel exists for the gap between "I trust my gut" and "I can afford a $25,000 investigations firm." It's the same primary-record check Kroll runs, structured for someone who has 90 seconds and $49 a month.

§ 02 — Where it earns the subscription

Four moments
it pays for itself.

Use case · 01

Pre-engagement client check

A new client wants to wire a deposit. Run a Quick Vet on their company and the principal before you take it.

Use case · 02

Subcontractor vetting

Bringing in a subcontractor for an enterprise project. Confirm they're who they say they are before they touch your client's data.

Use case · 03

Counterparty NDA review

About to sign an NDA with a stranger. A 90-second vet tells you whether the entity is operational, properly formed, or sanctioned.

Use case · 04

Speaking gig + sponsorship

Asked to speak at a conference, accept a sponsorship, or join an advisory board. Quick Vet the org first.

§ 03 — Where this audience lands
Recommended tier

§ 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.

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_
§ 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.

§ 04 — Common questions for this audience

The questions
we hear most.

I'm a solo. Can I really afford this and is it worth it?+

$49/month is one billable hour. If it catches one bad client — saving you an unpaid invoice, an awkward refund, or a reputational mess — it pays for the whole year. The vet itself takes 90 seconds; the math is straightforward.

Can I just use ChatGPT for this?+

ChatGPT will hallucinate sources and tell you what you want to hear. Sentinel labels every claim VERIFIED, REPORTED, INFERRED, or UNCONFIRMED, cites real records (OFAC, OpenSanctions, SEC EDGAR, court records), and flags common-name false positives. The discipline is the product.

Is this FCRA compliant if I want to vet a candidate I'm hiring?+

No. Sentinel is not a Consumer Reporting Agency and is not for hiring, firing, credit, insurance, or housing decisions. Use it for client vetting, vendor reviews, counterparty checks — not employment screening.
