Curious how others are thinking about “investable” vs “operating” businesses

Haven’t been as active on here for a bit, I’ve been heads down building something and looking at a lot of businesses from a different angle. One thing I keep noticing… There’s a big gap between a business that runs well, and one that’s actually investable. A lot of companies look solid on the surface Revenue is there, customers are there, things “work” But when you break them down, there are usually structural gaps Owner dependency, inconsistent acquisition, operational friction, etc. Not obvious day to day, but it shows up fast when you start thinking about scale or acquisition Curious how others here look at this When you’re evaluating a business, what’s one thing that immediately makes you lean in… or pass?
