Frequently Asked Questions

What makes lower middle market acquisition sourcing different from SMB?

LMM deals ($10M-$100M enterprise value) involve longer sourcing cycles (12-24 months from first contact to LOI), more sophisticated sellers who often have advisors, competition from PE-backed acquirers running formal processes, and the need for deeper pre-diligence before making initial contact. Quick, AI-generated Target Reports are critical for efficiently screening a large funnel.

What are the best practices for building an LMM acquisition pipeline?

Best practices include: (1) defining a narrow thesis by industry, geography, and size to concentrate relationship capital; (2) running Target Reports on every prospect before outreach; (3) building COI networks with M&A attorneys and accountants who advise LMM owners; (4) using a consistent qualification framework to score lead quality; and (5) maintaining a 24-month relationship horizon before expecting a transaction.

How many prospects should be in an LMM acquisition pipeline?

A healthy LMM pipeline should have 50-150 tracked prospects at any given time. From initial identification to closed deal, typical conversion rates are: 100 prospects → 20 qualified conversations → 5 LOIs → 1-2 closed deals. Pre-diligence tools like Argus let acquirers efficiently screen the top of that funnel before investing relationship capital.
