Our Approach
Joe Aberger founded 100-Day Advisors and created MandAPlaybook.com to increase the speed of integrations. Over several decades, he has seen a consistent pattern: integrations that drag on — mired in indecision, misalignment, and repeated restarts — underdeliver and those that move quickly and decisively exceed expectations. The correlation between integration speed and success is not a 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 even lost value.
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. While other consulting firms overwhelm teams with methodology and theory, we eliminate low value-add tasks, and move rapidly to align leaders, educate teams, and achieve synergies.
Our high-velocity approach:
- Locks in strategic alignment early so every decision reinforces the deal thesis
- Builds a fast, disciplined IMO that removes bottlenecks and drives accountability
- Creates clarity for employees so uncertainty never has a chance to take root
- Protects customers and revenue with coordinated, proactive communication
- Harmonizes systems and processes quickly to eliminate friction and unlock scale
- Drives synergy realization with precision —no drift, no delays
The first 100 days after close usually determine a deal's destiny. We convert 100-days of effort into 100-days of progress.
Let's get to work. Don't let time erode your deal's value.
Our Framework
A successful merger is secured through deliberate preparation, flawless initial execution, and sustained momentum. At-100 Day Advisors, we divide the integration lifecycle into three critical phases to accelerate the transition.
Phase 1: Pre-Close Planning (The Blueprint)
One of the biggest mistakes companies make is waiting for the ink to dry before planning the integration. We work behind the scenes during diligence and sign-to-close to jump start integrations.
Through rigorous synergy validation, we fact-check and structure the financial and operational assumptions in your investment thesis. We then establish robust integration governance by spinning up the Integration Management Office (IMO) and defining clear workstreams, charters, and decision-making protocols. Finally, our focus on risk mitigation ensures we identify Day 1 “showstoppers” across IT infrastructure, compliance, regulatory hurdles, and key talent retention before they can impact your timeline.
Phase 2: Day 1 Readiness (The Launch)
Day 1 is a critical cultural and operational milestone. We ensure that when the switch is flipped, your organization experiences zero downtime, your customers feel entirely secure, and your employees feel aligned.
We secure absolute operational readiness by ensuring core systems like payroll, email, and financial reporting work seamlessly from minute one. In parallel, we drive strategic change management and communications, deploying tailored messaging for customers, investors, and internal teams to eliminate anxiety and control the narrative. This is all backed by a comprehensive Command Center Deployment, launching a real-time tracking room to manage immediate issues, resolve roadblocks, and maintain total operational stability.
Phase 3: The First 100 Days (The Acceleration)
The first 100 days define the trajectory of the newly combined entity. We compress the timeline into an aggressive, structured sprint to realize quick wins and lock in long-term value.
Our team accelerates Tech Stack & Process Consolidation by fast-tracking the migration of redundant platforms, applications, and operating models across IT. We simultaneously manage Cultural & Team Integration to align leadership styles, optimize organizational design, and standardize corporate cultures around shared KPIs within HR. Ultimately, we 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 balance sheet.
