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 Modeling, 100-day playbook, Change Management — institutional integration methodology, run by your team.

Board-grade reporting on tap

Steering Committee decks, integration scorecards, synergy realization 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

16-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.

Enterprise security posture

SOC 2 Type II observation underway, ISO 27001 controls implemented, GDPR-compliant by architecture. AWS KMS envelope encryption · Aurora PostgreSQL Row-Level Security · audit logging on every access.

Skip the consulting pyramid

Big 4 firms staff every deal with a pyramid of junior consultants on slide-building, status reporting, and stakeholder coordination. The Agentic Transformation OS automates and augments that work — so you run bigger deals with your in-house team and Atlantic Intelligence, or hire a small bench of senior independents for the heavy lifts. No pyramid required.

Executives pull their own status

Your CFO or deal sponsor asks Claude Desktop, or any MCP client, for the latest Steering Committee pack — built from live project data, scope-controlled and revocable. No login, no chasing the deal team.
