## Summary
Most acquisitions fail before the integration even begins. With an 83% synergy failure rate, your Day 1 plan is either active or it is a liability.

## Full Content
Synergy is the most overused and under-delivered word in the boardroom. In 2026, 83% of deals in the UK destroy shareholder value. The primary killer is not the valuation. It is post-merger paralysis.

Integration starts during due diligence. If you wait until the completion party to figure out your systems and culture, you have already lost. You cannot scale on a fractured foundation. You need a Lead Auditor grade integration plan that is tracked like a P&L.

Simplif-i provides the oversight required to force rapid integration. We eliminate the friction between Day 1 and Day 100. Strategy is theory. Execution is ROI. Buy for the future, not the past.
