Due Diligence vs. 120-Day Reality

There is a massive gap between the strategy it takes to buy a business and the reality of running it. For the operators and searchers here who have acquired a company in the last 12 to 18 months, I’m curious to hear some of your "first 120 days" war stories. This community thrives on shared realities. If you are open to sharing, it would be great to hear your insights. 1. What was the biggest surprise you found after getting the keys (the buried Skeletons)? 2. What broke first when you tried to execute your initial 120-day plan? 3. How did you overcome those challenges, or what roadblocks are still preventing you from moving forward? Whether you’ve successfully smoothed things out or are currently in the trenches looking for a lifeline, sharing these realities is incredibly valuable for the folks here who are currently in LOI and need to know what they are walking into. Looking forward to reading your experiences. #ETA #SearchFund #Operations #DueDiligence #PostClose

Coming at this from the operations and AI side rather than the operator seat, so I don't have a personal acquisition war story to share - but I've worked with enough business owners through transitions to recognize the pattern you're describing. The thing that breaks first is almost never what anybody planned for. It's usually something invisible during diligence - a process that only worked because one specific person knew an unwritten rule, or a customer relationship that turned out to be personal to the seller, not institutional to the business. The 120-day plans that hold up are almost always the ones that treated the first 30 days as pure learning mode. Not fixing mode. Not improving mode. Just "become the most informed person in the room about how this thing actually works" mode. The owners who came in swinging - even with good intentions - almost always created problems they then had to spend the next 60 days cleaning up. Curious what the community says here. This thread is worth reading closely for anyone currently in diligence.
