Most deal failures in the lower middle market are not operational surprises. They are structural weaknesses that were visible early — dependency concentration, revenue narrative fragility, founder-coupled operations — but were misread as features of the business rather than preconditions for its collapse.
These patterns appear repeatedly — across funds, vintages, and deal types — yet are rarely formalized. Each allocator encounters them independently, absorbs the loss of time and capital, and moves on. The structural pattern itself is never captured.
Mapentir is an effort to reconcile lived deal experience with disciplined failure modeling through structured conversations with active capital allocators — to better understand which early structural signals are genuinely predictive and which are noise.
