Here are the top 4 QoE lessons straight from my Harvard talk. I was invited back to Harvard Business School to teach MBA students about QoE — the stuff that actually keeps buyers alive in deals. As a Harvard MBA myself, getting selected to train the next generation on due diligence was an honor. But more importantly, I recorded it. These are the 4 most popular videos in the 12-part series — the ones viewers keep coming back to: 1. Why Unreliable Financials Complicate Everything After 16 years in the deal business — including 3 years of part-time search while lying to my boss about why I was always distracted — I've seen what kills deals. Unreliable financials make everything harder. This video explains why, and how my experience means you're getting real advice, not guru slop. redacted 2. When Do You KILL Your Acquisition Deal & How Do You Know The hardest decision in any deal is walking away. Most buyers don't know when to kill a deal until it's too late. I break down the signals. redacted 3. ETA Business Due Diligence: Skip the Expensive Consultants You can't call Wall Street for a billion-dollar analyst report on a $10M HVAC company in Phoenix. So what do you do? I walk through scrappy, practical ways to get real industry intel — from Twitter to industry conferences to cold outreach that actually works. (Hint: "Hey, I'm betting my whole family's life on this" gets answers.) redacted 4. AI Due Diligence Sounds Cool Until You Lose Everything Everyone's excited about AI in diligence. Until it misses something that costs you your net worth, your career, and your family's future. This is the reality check. redacted This isn't theory. My caterer client went from $50K/year to $1M SDE buying an auto shop. That's why I do this work. The full 12-video playlist is there when you're ready. Start with the four that everyone else learned the most from. —Elliott
