7Seconds

Samantha Greenberg is the founder and serves as lead portfolio manager. She previously covered internet and media at Goldman Sachs and ran a consumer-internet book at Citadel's Surveyor Capital. The firm is structured as a concentrated, head-PM-led shop where she holds final decision-making authority over the portfolio.

The fund typically maintains roughly 15–25 long positions, paired with a short book focused on structurally challenged business models. This concentration reflects a high-conviction approach that deploys meaningful capital into each idea, avoiding the dilution that comes with tracking error-minimizing portfolios.

The firm invests across technology, media, and telecom, with a particular emphasis on enterprise software, fintech, digital health, and AI/ML infrastructure. Coverage extends to platform companies where product velocity creates widening competitive advantages that public market consensus models often fail to price in a timely manner.

7Seconds operates as a long/short equity fund focused purely on public markets. Although the firm's research intensity mirrors venture-style due diligence—mapping product roadmaps and developer ecosystems—it does not participate in private funding rounds or crossover allocations.

Idea generation relies on bottoms-up fundamental research that emphasizes product-level analysis, developer community engagement, and customer switching-cost evaluation. The firm's process draws on Greenberg's experience covering technology at both a major prime brokerage and one of the world's largest multi-manager platforms.
