Left Holding, my book on private equity-owned software companies, contains a diagnostic that helps enterprise software customers evaluate their PE-owned vendors. The problem it answers: customers see their vendor in fragments — procurement sees contracts, executives see the relationship, daily users see the product — and staff turnover on both sides keeps erasing what each side knew. Nobody holds the full picture.

Holding Power is that diagnostic as working software. It scores a vendor on nine signals, each resting on verbatim, source-cited evidence: privately, Muse Glimmer runs locally over the customer's own contracts, emails, and renewal quotes, so raw documents never leave their machine; publicly, Muse Wonder researches the open record, and every quote is verified against its source before it can affect a score. Runs repeat on a cadence, so change over time is auditable.
