PMSI Strategy LLP

Founded in 1989, PMSI Strategy is a London-based boutique consultancy focused on commercial due diligence, market intelligence, strategy consulting and performance improvement. It works with private equity firms, corporate clients and banks across the investment lifecycle, particularly in the UK lower mid-market.

PMSI assesses target markets, market size and growth, competitors, customer dynamics and business-plan assumptions. Its work spans buy-side and sell-side transactions, growth strategy, market entry, bolt-on acquisitions and refinancing support.

The firm is especially focused on four areas: built environment; business services, education and technology; industrials; and pharma and healthcare. Its differentiator is sector-specific commercial analysis delivered through a smaller, partner-led model rather than a broad generalist consulting platform.
