In-house, not retainer

Six things the Big 4 charge you per engagement that you stop renting.

Big 4 methodology, in-house

TSA Tracker, Day 1 plan, Synergy Modelling, 100-day playbook, Change Management — institutional integration methodology, run by your team, not rented per engagement.

Board-grade reporting on tap

Steering Committee decks, integration scorecards, synergy realisation reports — generated from live project data, refreshed in minutes, not days.

Functional + cross-functional workstreams

IT, HR, Finance, Operations, Legal, Commercial — each with templated playbooks, RAID logs, RACI, and AI-assisted work plan generation. Cross-functional dependencies tracked, not lost.

Cross-border by default

15-language support across project data, meeting intelligence, and reports. Run a US deal in English while your German subsidiary works in German with the same source of truth.

Common questions

How does this displace Big 4 spend if we still need bodies on the ground?

You will still hire pairs of hands for specific workstreams, but you stop renting the methodology, the templates, the playbooks, and the reporting. That is what the per-engagement retainer covers today. With Atlantic M&A those live in-house and run continuously across all your deals — pay once a year, run every deal on the same backbone.

Can we standardise our M&A playbook across business units and geographies?

Yes. Workspace-level templates and playbooks can be authored once and inherited by every project. Multi-language stakeholder briefings, region-specific compliance variants (GDPR, UK GDPR, CCPA, etc.) and per-business-unit RACI overrides are all first-class.

Does the AI see our deal data?

Atlantic Intelligence runs on AWS Bedrock with model invocations contained within your tenant boundary. No tenant data is used to train shared models. Tenant isolation enforced at the database layer with audit logging on every access.

What about active deals already in flight?

Migration from spreadsheet / Smartsheet / SmartDraw / SharePoint is a guided onboarding step on Pro and above. We import existing TSA logs, integration plans, and synergy models — no big-bang cutover. Live deals stay live during migration.

Procurement, security review, MSA — how long does Enterprise rollout take?

Standard Enterprise rollout including SAML/SSO, security review, MSA + DPA, and CSM kick-off lands in 4–6 weeks. We provide SOC 2 (Type II in progress) report, ISO 27001 alignment letter, GDPR Article 30 records, and DPIA template on request.

Stop renting the integration playbook. Own it.
