Our Focus: Middle-Market Private Markets Firms

Why THE MIDDLE MARKET?


As private markets evolve, middle-market firms face increasingly complex capital, ownership and growth needs — creating a growing role for long-term strategic partners.

The middle market is home to many of the industry’s most dynamic investment firms. These platforms are often expanding strategies, building teams, and institutionalizing their businesses at the same time.

That stage of development creates a distinctive opportunity in GP stakes investing — one that requires experience, judgment, and a true partnership mindset.

Bisonti focuses on firms at moments when strategic capital can make a meaningful difference: expanding capabilities, deepening teams, broadening distribution, strengthening infrastructure, or preparing for a new phase of growth. We act as a value-added strategic partner as well as a capital resource.

What is GP Stakes investing?

GP stakes investing involves acquiring a minority ownership interest in a private markets investment firm. For investors, it provides exposure to the recurring economics and long-term growth of the firm. For managers, it can provide aligned capital together with a strategic partner who can bring perspective, relationships and capabilities to support growth while preserving control and entrepreneurial independence.

Relationship-driven sourcing.

Bisonti’s investment opportunities are primarily sourced through long-standing relationships across the private markets ecosystem.

Our team’s experience working alongside investment firms provides direct access to managers as they expand their platforms and consider strategic partnerships.

Our long-standing focus on the middle market has created a deep network of relationships, knowledge and resources that compounds over time. This perspective allows us to engage with firms early, apply pattern recognition developed across market cycles, and build partnerships grounded in alignment and shared ambition.

Operating in the middle market allows us to evaluate firms at a level of depth that larger, more diversified platforms often cannot.

The middle market rewards depth. Because many firms are founder-led, culture-driven, and still evolving institutionally, evaluating them requires more than scale metrics. It requires understanding the quality of the investment engine, the strength of LP relationships, team dynamics, succession, governance, and the choices that shape a firm over time.

Each partnership is structured to align incentives, preserve independence, and support sustainable growth.

A highly diversified portfolio.

Our portfolio spans a range of private markets strategies and sectors. Each partnership supports the growth of exceptional investment firms while providing investors with diversified exposure to the underlying economics of private markets.
