Summary
The American Investment Council released a comprehensive report in August 2025 examining private equity's impact on small and mid-sized businesses across the United States. The findings underscore the sector's deepening commitment to companies outside the mega-cap buyout space, with over 21,000 business investments recorded in 2025 alone. Notably, 85% of these investments targeted businesses with fewer than 500 employees, reflecting a strategic concentration on genuinely small and mid-market enterprises rather than larger lower-middle-market companies.
The capital deployment figures are substantial. According to the report's underlying data, private equity invested $654.1 billion in small and mid-sized businesses during 2024, representing growth exceeding $100 billion compared to the prior year. This trajectory suggests continued momentum in smaller deal activity despite broader market volatility and the competitive landscape for capital allocation across alternative asset classes.
The report frames private equity's role beyond pure financial engineering. According to American Investment Council leadership, private equity firms function as "steadfast partners" providing not only growth capital but also strategic guidance and operational expertise. This value-add positioning is critical for institutional investors evaluating private equity exposure—the implication is that returns depend on active management and value creation rather than financial leverage alone.
The American Investment Council's collaboration with PitchBook, a respected deal data provider, lends credibility to the quantitative findings. The report includes case studies of specific portfolio companies benefiting from private equity backing, though detailed case-by-case analysis is referenced in the full report rather than summarized in the announcement.
This data point is particularly relevant for family offices, fund-of-funds managers, and institutional allocators evaluating small and mid-market private equity as a distinct asset class. The scale of deployment—over $650 billion annually—and the breadth of portfolio construction (21,000+ companies) suggest robust market depth and diversification opportunities in what has historically been considered a less liquid segment of the private equity market.
