Which startup failure case studies reveal scaling and team dynamics?

[Jason_T]

I'm developing a curriculum for an entrepreneurship program and want to include a module analyzing startup failure case studies, moving beyond just the usual post-mortem articles to examine the sequential decision-making and internal dynamics that led to collapse. I'm looking for detailed, well-documented examples where founders have been transparent about operational missteps, not just market fit. For educators or founders who have studied these failures deeply, which case studies offer the most instructive lessons on scaling too fast, team dysfunction, or flawed unit economics, and where did you find the most candid primary sources?
