Arcline is a private investment firm that seeks to build industrial compounders by investing in market-leading, mission-critical industrial platforms. The firm focuses on sectors defined by high-switching costs, regulatory barriers, and long product lifecycles, using strategic M&A and operational rigor rather than short-term financial engineering.

Arcline is a private investment firm with over $30 billion in assets under management. The firm seeks to build market-leading, mission-critical industrial platforms designed to consistently compound earnings over decades through strategic M&A, operational rigor, and disciplined capital allocation.

Since 2018, the firm has formed its portfolio through 160+ acquisitions and built scaled platforms in sectors defined by mission-critical performance, high-switching costs, regulatory barriers and long product lifecycles.

The firm utilizes a 60-person functionalized organizational structure with expert teams across research, business development, underwriting, and value creation. These teams operate as an integrated system in partnership with management teams to drive institutionalized sourcing and systematic research.
