About SentinelGraph

Public data is plentiful. Investigative context is not.

Sentinel Graph LLC is a Texas company building investigative lead intelligence that helps qualified users connect healthcare public records, understand why a record surfaced, and return to the source before drawing a conclusion.

Founder perspective

Built to make complex connections understandable.

Founder Jason Probert approaches the problem from outside traditional healthcare enforcement. That perspective shaped a simple product test: a reviewer should be able to understand what the data says, what it does not say, and where to verify it without learning an internal data vocabulary first.

01

Show the source

Every useful connection should lead a reviewer back to an attributable public record.

02

Preserve uncertainty

Candidate identity links, shared infrastructure, and unusual activity are questions to verify—not conclusions.

03

Design for humans

The product should explain why a record surfaced and what a reviewer can do next in plain English.
