Calling all Searchers — what’s the hardest part of evaluating a deal?

After spending time as a self-funded searcher, I’ve now started building tools to make the process less painful. But before going too far, I want to go back to first principles — and learn from you. When you're deep in a deal, what’s the part that trips you up the most? The first-pass model and research — trying to size the prize and pressure test assumptions? The growth/operating strategy — figuring out what you’d actually do if you bought it? The investor pitch — getting conviction across the line with your IC or your anchor? Or is it some other piece entirely? I’m not selling anything — just trying to learn what really slows people down, so I can build around actual bottlenecks, not imaginary ones.
