Thesis

Great Mountain Partners (GMP), founded in 2020 and based in New Haven, Connecticut, is a private markets investment firm with over $14 billion in AUM. GMP provides long-term capital solutions and strategic guidance to institutional investors, focusing on building platform companies in partnership with management teams. Their investment strategy centers on identifying companies with asset-intensive balance sheets within specific sectors that have the potential for secular growth and returns. Primary focus areas include Media & Entertainment (music, film, TV, sports, gaming), Infrastructure, Transportation, Energy (including clean and green energy), Financial Services, and Blue Tech (sustainable business models impacting the ocean economy like shipping, off-shore energy, water utilities, climate data aggregation, defense, and aquaculture). They also explore opportunities in adjacent markets and technologies driven by technology, demographics, politics, or regulation. GMP targets companies for controlling stakes or influential minority investments, prioritizing scalable platforms, differentiated intellectual property rights, and strategies that drive growth through operational value creation. While specific stage preferences are not explicitly detailed, their strategy suggests an interest in growth-stage companies. The firm invests across the United States and also considers global opportunities, particularly in sectors like Blue Tech. GMP employs economic, fundamental, and quantitative analyses, aiming to provide long-term capital solutions throughout the capital structure. They emphasize transparency, client service, and scale. In December 2025, they launched Saranac Holdings LP, a $600 million fund for media investments. The typical check size per investment deal is not publicly disclosed.
