European alternative asset manager Trimontium has appointed Graham Morrison as General Counsel, strengthening its legal and transaction execution capabilities as the firm expands its flexible capital solutions platform across Europe and North America. The appointment comes as private credit and special situations managers increasingly invest in institutional infrastructure to support complex cross-border transactions in a competitive alternative investments market.

Alternative asset manager Trimontium has expanded its senior leadership team with the appointment of Graham Morrison as General Counsel, reinforcing the firm’s legal, governance and transaction execution capabilities as it continues to scale its investment platform.

The appointment reflects a broader trend across the alternative investment industry, where private credit and flexible capital providers are investing in institutional-grade operational infrastructure alongside fundraising and portfolio growth. For firms operating across multiple jurisdictions, in-house legal expertise has become an increasingly important differentiator as transactions grow more complex and regulatory requirements continue to evolve.

Trimontium, which manages approximately US$1.5 billion in assets under management (AUM), focuses on providing flexible capital solutions across the capital structure. The firm structures bespoke financing for corporates through strategies spanning credit, special situations and other alternative investment opportunities.

Morrison joins Trimontium after spending 15 years at King Street Capital Management, where he served as a Managing Director across the firm’s global legal and investment teams. Before joining King Street, he practised as a corporate finance lawyer at Clifford Chance LLP, advising on complex corporate and cross-border transactions.

His experience spans legal advisory, governance, regulatory compliance and transaction execution across both public and private markets, expertise that is becoming increasingly valuable as alternative asset managers expand internationally and navigate evolving regulatory frameworks.

Supporting Cross-Border Investment Execution

Trimontium said Morrison’s appointment strengthens one of the firm’s defining operational characteristics: embedding transactional legal expertise directly within its investment platform rather than relying exclusively on external legal advisers.

This integrated approach is designed to accelerate deal execution while supporting increasingly sophisticated financing structures across multiple jurisdictions. According to the company, the firm has already completed several bespoke transactions across the United States and Europe, with continued expansion expected as investment opportunities broaden.

Embedding legal professionals alongside investment teams has become more common among larger alternative investment managers, particularly those operating in private credit, distressed investing and special situations. Internal legal capabilities can streamline negotiations, improve execution efficiency and enhance governance throughout the investment lifecycle.

Building Institutional Infrastructure

Founded by former Blackstone executive Vlado Spasov, Trimontium is positioning itself within the rapidly expanding private credit and flexible capital markets. Industry demand has increased as companies seek financing alternatives beyond traditional bank lending, creating opportunities for specialist investment managers capable of structuring customised capital solutions.

The firm’s investment strategy centres on originating and executing financing transactions across different layers of the capital structure, allowing it to support businesses with varying liquidity, refinancing and growth requirements.

Morrison’s appointment also reflects Trimontium’s emphasis on building institutional governance capabilities from its early stages. As regulatory expectations increase across global financial markets, investors are placing greater importance on operational resilience, compliance frameworks and risk management alongside investment performance.

The firm’s senior leadership includes several executives with previous experience at Blackstone. Chief Operating Officer Bally Sangar brings nearly three decades of experience across alternative investments, credit and asset management, while Managing Director Yaroslav Syzonov contributes expertise in capital solutions, corporate finance and special situations investing.

Private Credit Continues Its Growth Trajectory

The appointment comes during a period of sustained expansion in private markets. According to Preqin, global private debt assets under management have exceeded US$1.6 trillion, reflecting continued institutional demand for non-bank lending strategies. Meanwhile, McKinsey & Company has identified private credit as one of the fastest-growing segments within alternative asset management, driven by higher interest rates, tighter bank lending standards and increasing demand for bespoke financing solutions.

Competition among alternative asset managers is therefore extending beyond investment performance alone. Firms are increasingly differentiating themselves through specialist sector expertise, operational infrastructure, transaction capabilities and governance standards.

For institutional investors allocating capital to private markets, these organisational capabilities can influence manager selection alongside investment strategy and historical returns.

As Trimontium continues expanding across Europe and North America, strengthening its legal and governance infrastructure signals its intention to compete with more established alternative asset managers while supporting increasingly complex cross-border investment opportunities.

Market Landscape

Private credit and flexible capital solutions have become key areas of growth within alternative asset management as companies seek financing beyond traditional banking channels.

According to Preqin, global private debt assets under management have surpassed US$1.6 trillion, while McKinsey & Company reports that institutional investors continue increasing allocations to private markets in pursuit of portfolio diversification and enhanced returns.

Alternative asset managers are responding by investing in technology, governance, legal expertise and operational infrastructure to support increasingly sophisticated cross-border investment strategies and regulatory requirements.
