Comparison to Contemporaries
Compared with peers such as Arthur Rock and early-stage investors from Greylock, Rosen's approach combined operational depth with flexible deal structures. This versatility allowed Sequoia to remain competitive across varying market conditions.
While not the largest firm in assets under management, Sequoia's concentration in breakout tech winners delivered risk-adjusted returns that rivaled the largest global managers over multi-decade periods.
Current Structure and Portfolio Approach
Today, Sequoia continues with a broader global footprint, but many of the core principles trace back to Rosen's insistence on quality, governance, and founder support. The firm's current portfolio spans semiconductors, AI infrastructure, and enterprise software.
