One tactic I've been using to dig up more industries to pursue is looking at PE portfolio companies for inspiration. What I've been doing so far is looking at their websites and using their portfolio companies to reverse engineer my own proprietary outreach (e.g., NAICS codes, industry keywords).

The problem I'm running into is finding a centralized source of LMM PE firms and their portfolio companies. I've just been using Google so far, which doesn't feel efficient. I've also looked into Pitchbook, but subscription seems too pricy for my needs.

Does anyone have a good source for information on smaller PE deals?
