Reevemark Launches Sentinel, Agentic AI Simulation Designed for High-Stakes Communications

Capability builds working model of stakeholders to better inform decisions, tailor communication strategies and drive optimal outcomes

NEW YORK--(BUSINESS WIRE)--Reevemark today announced the launch of Sentinel, a proprietary, agentic AI simulation capability that enables clients to anticipate more precisely how stakeholder groups will react to their most important communications before they become public.

The moments that define a company's reputation unfold quickly, in public. In a crisis, proxy contest, or transaction, decisions about what to say, to whom, in what order and through which channels have historically been based on experience, under pressure, and with incomplete information about how stakeholders will react. Sentinel was custom designed to close that gap.

Sentinel is much more than a message testing device or substitute for polling and focus groups. It constructs a dynamic, working model of the stakeholders who shape the public response to a matter, including a counterparty, the media, investors, regulators, and the broader public, grounded in the facts of the situation and each actor's incentives, history and likely moves. It simulates how the moment can unfold, capturing the full chain of audience behavior: how each actor perceives a message, how they react, what actions they take and how they affect one another. Clients can pressure test strategies before going live to see where they hold, where they break, and what changes the result.

“Anyone who has been through a crisis, proxy fight or transaction rollout knows what it’s like to commit to a strategy without full information on how your stakeholders, the other side, the press or the market will respond,” said Adam Shapiro, Partner and Head of Digital & AI at Reevemark. “Sentinel gives our clients something our industry has never had: the ability to preview the full strategy and reaction, against a rigorous model of the actors involved, before a word is said in public. Sentinel merges decades of senior expertise with the analytical power of artificial intelligence and allows the communications strategy to be refined before you go public.”

Unlike message-testing tools, which stop at how audiences receive individual statements, Sentinel models the entire strategy: what to say, to whom, through which channel and in what order. And unlike standalone software, Sentinel is delivered by Reevemark under engagement, pairing the simulation's evidence with senior practitioner judgment. Sentinel can be customized for long-term communication programs or for special situations: shareholder activism and proxy contests, litigation and regulatory matters, crisis and reputation events, M&A and corporate transactions, leadership and governance transitions, and sensitive public announcements. Confidentiality is engineered into the capability itself.

Sentinel is available now in early access for select clients and partners and is patent pending. Learn more and request a confidential briefing at www.reevemark.com/sentinel.
