Startup-valuation is a critical area of research within entrepreneurial finance, but research on this topic is less consistent and thorough than overall valuation research. Peer-reviewed studies express a range of divergent views and approaches, and the focus varies widely. To bring clarity to this fragmented field, we conduct a systematic literature review, examining 87 peer-reviewed studies published between 1985 and 2020. We analyze these publications in detail and identify 36 startupvaluation drivers and cluster them into five macro-themes: Entrepreneur Characteristics; Firm Characteristics; Investor Characteristics; Market Conditions; and Deal Conditions. We then describe the valuation-impact of these drivers on startups. The range of drivers identified in the literature gives rise to construction of an integrative meta-model based on the macro-themes, placed into appropriate chronological position in the valuation process Our study also identifies key research-gaps and highlights promising directions for exploring the startup-valuation field.
