Three definitions of a target universe
Firms mean different things by the word, and the ambiguity costs weeks.
“Target universe” sounds like a fixed thing, but three different definitions of it circulate inside most lean LMM firms, and mixing them up costs weeks of avoidable rework.
The screen-first universe
The universe is whatever a database filter returns for a set of industry codes, revenue bands, and geographies. It's fast to produce and, in the lower middle market, frequently wrong — leading sourcing tools estimate private LMM revenue with 60–80% error, and industry-code taxonomies routinely misclassify founder-led companies.
The thesis-native universe
The universe is every company that fits the thesis as actually articulated, including the exclusions and the customer-relationship or compliance-driven definitions a coarse taxonomy can't express. This universe is judged company-by-company against the thesis, not against a category label, and it's the version worth building infrastructure around.
The living universe
The universe is a continuously re-scored feed, not a point-in-time export: it updates as companies change, gets sharper as research and closed-deal feedback accumulate, and surfaces new entrants automatically as they cross into range. A static universe decays within 60 to 90 days; a living one compounds.
The ambiguity costs weeks because a team that thinks it's maintaining a thesis-native, living universe is often actually re-running a screen-first export every quarter and calling it the same thing. Naming which one you mean is the first step toward building the one that actually compounds.
