The entrepreneurship literature has traditionally emphasized the human capital of founders and founding teams. Yet as startups move from founding to scaling, their performance increasingly depends on how they engage with labor markets beyond the founding and top management teams. We argue that startup labor markets constitute a distinct and underexplored strategic domain in entrepreneurship research, one that governs how ventures attract, structure, develop, and retain talent under conditions of uncertainty. We organize this agenda around three structural features that distinguish startups from more established firms and generate distinctive labor market frictions: (1) uncertainty about product–market fit, which creates ambiguous roles and learning environments; (2) resource and reputational scarcity, which complicates pricing and signaling to prospective employees; and (3) high failure risk, which elevates career risk and shapes mobility expectations. For each feature, we examine implications for both startups (the demand side) and workers (the supply side), highlighting the strategic tradeoffs embedded in hiring, compensation, job design, and mobility. We identify priority directions for future research across entry and sorting, work and incentives, development and learning, and mobility and market shaping, and we discuss data sources that enable empirical progress. Overall, we aim to reorient strategic entrepreneurship research from a primary focus on entrepreneurial founding toward a labor-mediated view of enterprise scaling, in which talent and labor market strategy are central to competitive advantage.
