Agentic simulation built for your highest-stakes moments.
Sentinel builds a working model of the real actors in your situation: the other side, the press, the regulators, the audiences that matter. It simulates how the moment unfolds across many scenarios, so your comms strategy is pressure tested, not guessed.
You can’t run the moment twice. High stakes decisions are made on experience, under pressure, with incomplete information about how your stakeholders will react.
Pressure testing them demands practitioner judgment and a rigorous model of real behavior. Reevemark built Sentinel at exactly that intersection.
Evidence, backed by wisdom.
Predict what they’ll do, not just what they think
Sentinel models the full chain of audience behavior, from perception, to reaction, to action, to how audiences move one another.
Model the whole strategy, not just the message
Most tools stop at message testing. Sentinel builds the full approach: what to say, to whom, through which channel, in what order.
Turn hard-earned experience into proof
Sentinel turns decades of practitioner judgment into model-backed evidence.
Judgment, amplified by simulation.
Model the actors
We build a working model of every actor who shapes the outcome: their incentives, history, and likely moves, grounded in the facts of your matter.
Run the scenarios
Sentinel simulates how the situation may unfold many times over, and how each actor responds to what you say, when, and to whom.
See where it holds or breaks
The strategy meets its failure modes in advance, not in public.
The simulation does the testing. Reevemark partners do the judging.
The dynamic, played out many times over.
Sentinel runs the situation forward again and again, surfacing where the strategy holds and where it breaks, so failure modes show up in advance, not in public.
Moments where a single decision shapes the outcome.

Anticipating an activist’s sequence before you answer it.

Built for matters where discretion is an obligation.
Confidentiality on Sentinel is not a single setting. The level of containment is matched to the sensitivity of each matter and adjusted as it evolves, scaling from public data to the strictest confidential materials.
Set per matter, not a fixed mode.
