Integration Complete at 100-Days

At 100-Day Advisors, we do not just manage integrations. We accelerate them. Our consultants get the majority of the integration work of our clients, regardless of their size, complete by 100 days post-close. That’s our standard.

Why speed matters

Integrations that drag on ... underdeliver.

The correlation between speed and success is no coincidence. Uncertainty is expensive. Every day that employees don't know their fate, customers aren't sure who to call, and systems remain disconnected is a day of delayed or lost value.

The first 100 days after close usually determine a deal's destiny.

Joe Aberger founded 100-Day Advisors and created MandAPlaybook.com to increase the speed of integrations and their odds for success.

Our framework

Three Phases. One Sprint to 100 Days.

We compress the integration timeline into three critical phases.

Phase 01

Pre-Close Planning

Too many acquirers wait until the ink is dry on the deal before starting the planning process. High-speed integrations require pre-close preparation.

Phase 02

Day 1

When the switch is flipped, your organization must be ready to go. Day 1 is a critical cultural and operational milestone.

  • Ensure core systems like payroll, email, and financial reporting work seamlessly.
  • Communicate tailored messages for employees, customers, and investors to eliminate anxiety and control the narrative.
  • Operate Day 1 War Room that manages immediate issues, resolves roadblocks, and maintains total stability.

Phase 03

The First 100 Days

Quick wins are achieved and momentum is maintained so ground is covered at very rapid clip.

  • Manage HR integration to align leadership styles, optimize organizational design, and standardize corporate cultures around shared KPIs.
  • Anchor the entire process in aggressive synergy realization, pursuing immediate cross-selling opportunities and cost-reduction targets to ensure the promised value shows up clearly on the income statement.
  • Accelerate IT integration by fast-tracking the migration of redundant platforms, applications, and operating models.
