Kunstler joins from Bain Capital, where he spent 18 years as a partner in the firm's European private equity business, bringing significant institutional investment experience to his new role.

At Arini, Kunstler will sit on the private credit investment committees and lead development of the firm's hybrid capital strategy. According to Hamza Lemssouguer, Arini's founder and chief investment officer, Kunstler's background as a private equity investor will complement the firm's broader investment platform, which combines public and private credit strategies with fundamental, sector-focused research capabilities.

The hybrid capital strategy represents a strategic expansion of Arini's financing toolkit, enabling the firm to structure investments across different points of the capital stack rather than limiting itself to traditional senior lending positions. This approach positions Arini to address evolving market demands, particularly as borrowers and sponsors seek alternatives to conventional financing in the current environment.

Arini currently manages more than $20 billion in assets and has built strategies spanning both public and private credit markets. The firm's expansion of its private capital offering reflects favorable market conditions for managers capable of providing flexible, long-term capital to businesses seeking non-traditional financing solutions. The appointment underscores Arini's commitment to broadening its range of financing solutions and enhancing its competitive positioning in the alternative credit space.
