When a large company acquires a startup, the natural tendency is to impose its standardized processes. Successful integration requires a balance: knowing which systems to standardize for leverage while allowing the acquired team to maintain its freewheeling, startup-style execution.

Veteran dealmaker Andy Cohen argues against a "win-at-all-costs" mentality in M&A. True success, particularly in tech deals where talent is key, comes from ensuring the acquired team feels the outcome is fair and their future is promising. If one side feels they lost, the integrated entity will fail.

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.

Palo Alto Networks' M&A playbook defies convention. Instead of integrating an acquisition under existing managers, they often replace their own internal team with the acquired leaders. The logic is that the acquired team won in the market with fewer resources, making them better equipped to lead that strategy forward.

The "conquering hero" approach of forcing an acquired company to adopt your processes is the cardinal sin of M&A. Omar Tawakol's experience at Oracle showed that protecting an acquisition's unique workflows and incentives leads to growth, while rapid, forced integration destroys value.

The Clapp acquisition began when Lemlist's CEO sent a random cold email to the founder. Despite competing against larger companies who bid more, Lemlist won the deal by focusing on product synergies and team fit, proving that a strong relationship and shared vision can be more valuable than the highest offer.

Instead of only the buyer investigating the target, successful M&A involves "reverse due diligence," where the target is educated about the buyer's company. This transparency helps the target team understand how they will fit, fostering excitement and alignment for the post-close journey.

A five-step framework—Deep Dive, Battle Test, Communicate, Run Funnel, Commit to Close—is designed for smaller companies to execute M&A with focus and agility. It emphasizes using a firm but flexible framework over a rigid, step-by-step playbook.
