Quick take
Pre-LOI diligence is about early conviction and red-flag detection, not full verification.
Glossary term
Pre-LOI Due Diligence
Pre-LOI due diligence is the focused buyer review that happens before a letter of intent is signed. It is designed to pressure-test the deal thesis, surface obvious red flags, and decide whether the opportunity deserves exclusivity and deeper diligence investment.
Why it matters
A disciplined pre-LOI process prevents teams from overcommitting time and cost to weak opportunities while preserving the early signal that should carry into full diligence if the deal moves forward.
