M&A employee communications

Day one of the deal, one story on both sides.

Acquired teams decide in the first weeks whether they belong. ChangeEngine runs the people side of the deal: leaders briefed before the news, a clear day-one welcome, a 100-day integration path and answers to the questions everyone's asking, in every language and on every channel. From our app, or the AI assistant you already use.

Why integrations stumble

The deal closes. The people side starts from scratch.

Every acquisition brings a new team that doesn't know who you are, what's changing or who to ask. Leaders are stretched, lists don't exist yet, and silence fills with rumors.

Silence

Rumors move faster than updates

A clear plan for what to say, when and to whom, from announcement to day 100.

Two systems

No clean list of who's who

Bring both workforces in from either HRIS and segment by legacy company, site and role.

Two cultures

Two brands, two ways of working

One look, one voice and one hub, so everyone feels like one company sooner.

The first 100 days

Employee Hub AI

One place for everything a new colleague needs

Acquired teams get a hub from day one: who we are, what's changing for them, benefits, contacts and an HR agent that answers in their language. It opens from a text link, so it works before IT accounts are merged.

✓Works before email and IT systems are merged
✓Personal to each person's site, role and legacy company
✓HR Knowledge Agent answers benefits and pay questions
✓Shows only the changes that apply to each person

Under the hood

The modules that carry an integration

M&A comms aren't a separate tool. They're the platform's modules working together, so every message knows who joined, from where, and what changes for them.

Forward deployed engineering

Need something we don't do out of the box? Your engineer builds it.

ChangeEngine provides a forward deployed engineer who builds whatever custom apps your integration needs, and ships them inside your Employee Hub with your branding and your data.

Reach the new team before IT does

Acquired employees often don't have your email yet. Two-way SMS, WhatsApp, QR posters and the hub reach them from day one, while Teams, Slack and email cover everyone already connected.

For IT and security

Why IT says yes in one meeting

There is no new app for employees, no code to maintain and nothing to host. ChangeEngine connects to the systems IT already runs through standard, auditable integrations.

Certified

Certified, not self-attested

SOC 2 and ISO 27001 certified and GDPR compliant, with documentation ready in the Trust Center.

Identity

SSO on day one

SAML or OAuth single sign-on with optional 2FA. Employees reach the hub with Google or Microsoft sign-in.

Data

Your data stays in your region

Encryption in transit and at rest, with data residency in the US, EU or Canada. Content is generated inside your ChangeEngine environment.

AI governance

No shadow AI

The MCP runs inside the assistant you already approved and acts with the signed-in user's permissions. Nothing sends without an approval.

Integrations

Through the front door

Workday, ADP, BambooHR, UKG and 75+ more, plus Active Directory, Teams, Slack and SharePoint, all through standard APIs.

Control

Roles and approvals

Role-based permissions and approval steps, so comms, legal and leadership sign off before anything goes out.

FAQ

Mergers & Acquisitions questions, answered

What does ChangeEngine do in an acquisition?

It runs the employee communication side: briefing leaders, welcoming the acquired team, explaining what changes, answering questions and tracking how the integration is landing by site and legacy company.

Can we keep it confidential before the announcement?

Yes. Drafts, audiences and schedules stay restricted to the people you choose until you approve the send.

How do we reach people who aren't in our systems yet?

Import the acquired workforce from their HRIS or a file, then reach them by SMS, WhatsApp or the hub, before email and IT accounts are merged.

Can we run comms for both brands?

Yes. Keep separate brand kits during the transition, then move everyone to one look and voice when you're ready.

How do we know if the integration is working?

Pulse surveys and Engagement Analytics show reach, questions and sentiment by legacy company, site and role.

Can we run it from an AI assistant?

Yes. The ChangeEngine MCP lets ChatGPT, Claude, Gemini or Copilot draft and schedule integration comms, with your normal roles and approvals in place.
