Approach
The firm's approach to technology investing combines patient capital with deep operating engagement. Each investment is held to the same standard as any other commitment — a clear path to value, an aligned partner, and a long-term view.
Rosen Partners does not chase momentum. Instead, the firm focuses on businesses with durable unit economics and a defensible position in their category, where capital and networks can meaningfully accelerate the outcome.
Defense Tech
Defense technology is a significant part of the firm's technology practice. Rosen Partners invests in companies building the systems, platforms, and capabilities that underpin national security — from autonomy and sensors to secure communications and dual-use software. The firm backs founders solving hard, mission-critical problems for government and commercial customers.
These investments are pursued with the same long-cycle discipline applied across the firm's portfolio: alignment with operating partners, conviction in the underlying thesis, and patience through development and procurement timelines.
Infrastructure
Digital infrastructure — data centers, fiber, towers, and the systems that support them — represents a natural extension of the firm's real estate and infrastructure practice. The same underwriting principles apply: a long-duration asset, a durable cash flow, and a defensible competitive position.
