Contrary to standard M&A practice where integration begins post-close, Brad Jacobs makes immediate, unrestricted access to a target company's employees and operations a non-negotiable term upon signing. This allows his team to begin the integration process weeks or months earlier.

The most critical lesson from integrating 22 acquisitions wasn't about perfecting data migration. Instead, success was determined by spending significant time with acquired teams *before* migrating core systems. This human-centric approach ensures teams feel supported and bought into the new direction, which is more impactful than technical flawlessness.

The success of an AI roll-up hinges on effective technology implementation. Therefore, the primary filter for acquiring a company is not just its financials but whether its leadership and culture are genuinely eager to adopt AI and transform their operations. This cultural fit is non-negotiable.

Successful large-scale acquirers remain nimble, flexing their own processes to suit the acquired company rather than force-fitting it into a rigid corporate structure. This preserves the culture and talent that made the company valuable, preventing value destruction and keeping the new team engaged.

Many M&A teams focus solely on closing the deal, a critical execution task. The best acquirers succeed by designing a parallel process where integration planning and value creation strategies are developed simultaneously with due diligence, ensuring post-close success.

Deals fail post-close when teams confuse systems integration (IT, HR processes) with value creation (hitting business case targets). The integration plan must be explicitly driven by the value creation thesis—like hiring 10 reps to drive cross-sell—not a generic checklist.

Framing M&A like a marriage, rather than a transaction, fosters a long-term perspective. Sourcing is dating to find value alignment, the Letter of Intent is the engagement, and post-close integration is the marriage itself—the phase where the real, hard work of building a successful union begins.

During a merger, prioritize people over process. Technical integration is secondary to building trust between teams. Use simple, cultural activities like joint happy hours and "show-and-tells" about the tech stack to humanize the engineering effort and foster empathetic collaboration early on.

A one-size-fits-all integration can destroy the culture that made an acquisition valuable. When State Street acquired software firm CRD, it intentionally broke from its standard process, allowing CRD to keep its brand identity, facilities, and even email domain to preserve its creative culture and retain key talent.
