Quantifying Founder-Market Fit: A Machine Learning Approach to Startup Success Prediction

Abstract

The high failure rate of early-stage startups poses persistent challenges for venture capitalists and innovation policymakers alike. Although Founder-Market Fit (FMF), defined as the alignment between a founder's background and the domain of their startup, has rarely been systematically quantified, it is widely acknowledged in practice as a key determinant of success. In this paper, we present a novel, data-driven framework to operationalize and predict FMF using machine learning and natural language processing. We construct high-dimensional representations of founder profiles by aggregating structured data from Crunchbase, LinkedIn, and X, and apply transformer-based embeddings to quantify semantic alignment with industry verticals. FMF scores, together with features related to prestige, experience, seniority, and inferred personality traits, are incorporated into supervised models to predict startup success. Our findings show that FMF significantly improves predictive performance over baseline models and remains robust across weighting schemes and learning algorithms. By providing a scalable, interpretable, and auditable approach to founder evaluation, this study advances algorithmic entrepreneurship and offers practical insights for investors, accelerators, and policymakers seeking to improve early-stage startup assessments
